Answer:
NOTE: THIS IS AN EXAMPLE
Step-by-step explanation:
Let the Yellow Marbles be “X” and Red Marbles be “Y”
Total is 65, so X+Y = 65
Since we know that Yellow Marbles are 5 more than 4 times red marbles, let us convert that in terms of X and Y as well.
i.e, X = 4Y+5
Now replace X with (4Y+5) in the first equation we wrote above.
(4Y+5)+Y = 65
i.e, 5Y+5 = 65
5Y = (65–5),
5Y = 60
Therefore Y = 60/5 = 12
we know total is 65
So X= 65-Y
X=65–12 = 53
Therefore, the number of Yellow Marbles are 53 and the Red ones are 12.
Jill counts 150 peach trees on 1/2 of the land she owns. She determines that there are 5 trees for every 1,000 square feet of land. About how many acres of land does Jill own? 1 acre= 43,560 square feet.
Jill owns approximately 60,000 acres of land.
Let's first find out how many trees Jill has per acre based on the information given.
Jill has 150 peach trees on 1/2 of her land, which means she has 300 peach trees on her entire land. If there are 5 trees for every 1,000 square feet of land, we can calculate the total square feet of land that Jill owns:
[tex]\[ \text{Total trees} = \text{Trees per acre} \times \text{Total acres} \]\[ 300 = \frac{5}{1000} \times \text{Total acres} \][/tex]
Solving for the total acres:
[tex]\[ \text{Total acres} = \frac{300}{\frac{5}{1000}} \]\[ \text{Total acres} = \frac{300 \times 1000}{5} \]\[ \text{Total acres} = \frac{300000}{5} \]\[ \text{Total acres} = 60000 \][/tex]
Now, we can convert the total acres from square feet to acres using the conversion factor given:
[tex]\[ \text{Total acres in square feet} = 60000 \times 43560 \]\[ \text{Total acres} = \frac{60000 \times 43560}{43560} \]\[ \text{Total acres} = 60000 \][/tex]
So, Jill owns approximately 60,000 acres of land.
Jill owns approximately 1.38 acres of land.
To find out how many acres of land Jill owns, we first need to determine the total number of peach trees on all her land.
Since she counts 150 peach trees on half of her land, we can assume there are 300 peach trees in total (since half of her land has 150 trees and the other half will also have 150 trees).
Now, if there are 5 trees for every 1,000 square feet of land, we can set up a proportion to find out how many square feet of land these 300 trees occupy:
[tex]\( \frac{5 \text{ trees}}{1000 \text{ square feet}} = \frac{300 \text{ trees}}{x \text{ square feet}} \)[/tex]
Cross-multiplying, we get:
[tex]\( 5x = 300,000 \)[/tex]
Dividing both sides by 5:
[tex]\( x = 60,000 \)[/tex]
So, Jill's 300 peach trees occupy 60,000 square feet of land.
To convert this to acres, we use the conversion factor provided: [tex]1 acre = 43,560 square feet.[/tex]
[tex]\( \text{Number of acres} = \frac{60000}{43560} \)[/tex]
[tex]\( \text{Number of acres} = 1.38 \)[/tex]
Complete correct question:
Jill counts 150 peach trees on 1/2 of the land she owns. She determines that there are 5 trees for every 1,000 square feet of land. About how many acres of land does Jill own? [tex]1 acre= 43,560 square feet.[/tex]
One angle of an isosceles triangle measures 118°. Which other angles could be in that
isosceles triangle? Choose all that apply.
Answer:
that is the solution to the question
Final Answer:
31 degree.
Explanation:
The sum of the interior angles of any triangle in a Euclidean plane is always 180°.
Given one angle of the isosceles triangle measures 118°, we can find the possible measures of the other two angles using the following steps:
Step 1: Calculate the sum of the two remaining angles.
Since the total sum of the angles in a triangle is 180° and we already have one angle measuring 118°, we can subtract the known angle from 180° to find the sum of the remaining two angles:
180° - 118° = 62°
Step 2: Divide the sum between the two equal angles.
Because the triangle is isosceles, the remaining two angles are equal in measure. We found their sum (62°), so to determine each individual angle's measurement, we divide that sum by 2:
62° ÷ 2 = 31°
Thus, both of the remaining angles in the isosceles triangle must measure 31° each.
In conclusion, an isosceles triangle with one angle measuring 118° will have the other two angles both measuring 31°.

The workers union at a certain university is quite strong. About 96% of all workers employed by the university belong to the workers union. Recently the workers went on strike, and now a local TV station plans to interviews a sample of 10 workers, chosen at random, to get their opinions on the strike.
A) Estimate the number of workers in the sample who are union members by giving the mean of the relevant distribution (that is, the expectation of the relevant random variable).Do not round your response.
B) Quantify the uncertainty of your estimate by giving the standard deviation of the distribution. Round your response to at least three decimal places.
Answer:
[tex]X \sim Binom(n=10, p=0.96)[/tex]
The probability mass function for the Binomial distribution is given as:
[tex]P(X)=(nCx)(p)^x (1-p)^{n-x}[/tex]
Where (nCx) means combinatory and it's given by this formula:
[tex]nCx=\frac{n!}{(n-x)! x!}[/tex]
Part a
For this case the expected value is given by:
[tex] E(X) = np = 10 *0.96 = 9.6[/tex]
Part b
For this case the standard deviation is given by:
[tex] \sigma = \sqrt{np(1-p)}= \sqrt{10 *0.96*(1-0.96)}= 0.620[/tex]
Step-by-step explanation:
Previous concepts
The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".
Solution to the problem
Let X the random variable of interest "number of workers in the sample who are union members", on this case we now that:
[tex]X \sim Binom(n=10, p=0.96)[/tex]
The probability mass function for the Binomial distribution is given as:
[tex]P(X)=(nCx)(p)^x (1-p)^{n-x}[/tex]
Where (nCx) means combinatory and it's given by this formula:
[tex]nCx=\frac{n!}{(n-x)! x!}[/tex]
Part a
For this case the expected value is given by:
[tex] E(X) = np = 10 *0.96 = 9.6[/tex]
Part b
For this case the standard deviation is given by:
[tex] \sigma = \sqrt{np(1-p)}= \sqrt{10 *0.96*(1-0.96)}= 0.620[/tex]
A. The mean number of union members in a sample of 10 workers is 9.6. B. The standard deviation is approximately 0.620.
A) Mean (Expectation) Calculation
The number of union members in the sample can be modeled using a binomial distribution since each worker either is or isn't a union member.
For a binomial distribution, the expectation (mean) is given by:
Mean (μ) = n * p
where n is the number of trials (in this case, the number of workers in the sample), and p is the probability of success in a single trial (the probability that a worker is a union member).
Here, n = 10 and p = 0.96, so:
Mean (μ) = 10 * 0.96 = 9.6
B) Standard Deviation Calculation
For the same binomial distribution, the standard deviation (σ) is given by:
σ = √(n * p * (1 - p))
Substituting the given values:
σ = √(10 * 0.96 * (1 - 0.96))
= √(10 * 0.96 * 0.04)
= √0.384
= 0.620
Thus, the standard deviation of the distribution is approximately 0.620
Determine any data values that are missing from the table, assuming that the data represent a linear function.
Answer:

Stan's lawn mower had ⅛ of a gallon of gasoline in the tank. Stand started mowing and used all of the gasoline. He put 6/10 of a gallon of gasoline in the tank. After he mowed, ¼ of a gallon was left in the tank. What was the total amount of gasoline Stan used? *
Answer:Stan used 19/40 of a gallon of gasoline.
Step-by-step explanation:
At first, Stan's lawn mower had 1/8 of a gallon of gasoline in the tank. When it got finished, he put 6/10 of a gallon of gasoline in the tank. It means that the number of gallons of gasoline that he has already put in the tank is
1/8 + 6/10 = 29/40 of a gallon.
After he mowed, 1/4 of a gallon was left in the tank. Therefore, the total amount of gasoline Stan used is
29/40 - 1/4 = 19/40 of a gallon
Final answer:
Stan used a total of 0.475 gallons of gasoline for mowing, calculated by adding the initial and added amounts of gasoline and then subtracting what was left after mowing.
Explanation:
To calculate the total amount of gasoline Stan used, we will first need to know the total gasoline added to the mower and then subtract the amount left after mowing.
Firstly, Stan started with ⅛ of a gallon (which is the same as 0.125 gallons) and added ⅔ of a gallon (0.6 gallons) to the tank. To find out how much gas was in the tank after refilling, we add these two amounts together:
0.125 + 0.6 = 0.725 gallons (total gas in the tank after refilling).
Once Stan finished mowing, he had ¼ of a gallon left in the tank. We need to subtract this amount from the total gas in the tank after refilling to find out the amount of gas used:
0.725 - 0.25 = 0.475 gallons (total gas used by Stan while mowing).
Therefore, Stan used a total of 0.475 gallons of gasoline for mowing.

Using the side of a building as one side and fencing for the other three sides, a rectangular garden will be constructed. Given that there are 60 feet of fencing available, determine the dimensions that would create the garden of maximum area and identify the maximum area. Enter only the maximum area. Do not include units in your answer.
Answer:
The dimensions that would create the garden of maximum area are 30 feet and 15 feet
The maximum area is 450 feet²
Step-by-step explanation:
The garden is fencing for three sides only, That means the length of the fencing is equal to the sum of the length of the three sides
Assume that garden is y feet long and x feet wide and the fencing will cover on side of y feet and two sides of x feet
∵ The sum of the length of the 3 sides = y + x + x
∴ The sum of the length of the 3 sides = y + 2x
- The length of the fencing is equal to the sum of the sides
∵ The fencing is 60 feet
- Equate y + 2x by 60
∴ y + 2x = 60
- Find y in terms of x by subtracting 2x from both sides
∴ y = 60 - 2x
To find the dimensions which make the maximum area, find the area of the garden, then substitute y by x, and differentiate it with respect to x, then equate the differentiation by 0 to find the value of x, and substitute this value in the equation of y to find y and in the equation of the area to find the maximum area
∵ The formula of the area of a rectangle is A = l × w
∵ l = y and w = x
∴ A = x y
- Substitute the value of y above in A
∵ A = x(60 - 2x)
- Multiply bracket by x
∴ A = 60x - 2x²
Now differentiate x with respect to x
∵ A' = 60(1) - 2(2)x
∴ A' = 60 - 4x
- Equate A' by 0 to find x
∴ 0 = 60 - 4x
- Add 4x to both sides
∴ 4x = 60
- Divide both sides by 4
∴ x = 15
- Substitute the value of x in the equation of y to find it
∵ y = 60 - 2(15)
∴ y = 30
The dimensions that would create the garden of maximum area are 30 feet and 15 feet
To find the maximum area substitute x by 15 in the equation of the area
∵ A = 60(15) - 2(15)²
∴ A = 900 - 450
∴ A = 450
The maximum area is 450 feet²
A maximum area for the rectangular garden is achieved when the rectangle is a square, having side lengths of 15 and 30 feet. This yields an area of 450 square feet.
Explanation:The question is a classic problem of optimization in Mathematics, where we want to maximize the area of the garden given a constraint, which in this case, is the total length of fence available. We consider the garden to have sides of lengths x and y, where y is the side against the building, and we don't need fencing there. Because we're working with a total of 60 feet of fencing, the length of the other three sides of the rectangle (two sides of length x, one side of length y) give us the equation 2x + y = 60.
We want to maximize the area of the rectangle, which is given by A = x*y. We can substitute y from the above equation into this to give A = x*(60-2x) = 60x - 2x^2. This is a quadratic function and it attains its maximum when x = -b/2a. Here, a = -2, b = -60, so x is 15 feet. The maximum area occurs when x and y are equal, which is when the rectangle is a square.
So, the corresponding value of y = 60 - 2*15 = 30 feet. Therefore, we have a maximum area of 15*30 = 450 square feet.

An architect wants to draw a rectangle with a diagonal of 15 centimeters. The length of the rectangle is to be 6 centimeters more than twice the width. What dimensions should she make the rectangle
Answer:
She should make a rectangle with dimensions 14.4 cm by 4.2 cm.
Step-by-step explanation:
The diagonal of a rectangle is represented by [tex]\sqrt{length^2+width^2}[/tex].Area of rectangle is = length×widthPerimeter of a rectangle = 2(length+width).Assume x be the width of the rectangle.
The length of the rectangle is to be 6 cm more than twice the width.
The length of the rectangle is= (2x+6) cm
Then the diagonal of the rectangle is [tex]\sqrt{length^2+width^2}[/tex]
[tex]=\sqrt{(2x+6)^2+x^2}[/tex]
[tex]=\sqrt{4x^2+24x+36+x^2}[/tex]
[tex]=\sqrt{5x^2+24x+36}[/tex] cm
According to the problem,
[tex]\sqrt{5x^2+24x+36}=15[/tex]
Squaring both sides
[tex]\Rightarrow{5x^2+24x+36}=15^2[/tex]
[tex]\Rightarrow{5x^2+24x+36}=225[/tex]
[tex]\Rightarrow{5x^2+24x+36-225=0[/tex]
[tex]\Rightarrow{5x^2+24x-189=0[/tex]
⇒5x²+45x-21x-189=0
⇒5x(x+9)-21(x+9)=0
⇒(x+9)(5x-21)=0
⇒x+9=0 or, 5x-21=0
[tex]\Rightarrow x=-9, \frac{21}5[/tex]
⇒x= -9, 4.2
Since the width of a rectangle can not negative.
So, x=4.2 cm
The width of rectangle is = 4.2 cm
The length of the rectangle is =(2×4.2+6)
=14.4 cm
She should make a rectangle with dimensions 14.4 cm by 4.2 cm.
To find the dimensions of a rectangle with a given diagonal length and a relationship between its length and width, we can set up a system of equations and use the Pythagorean theorem.
Explanation:To solve this problem, we can set up a system of equations using the given information. Let's assume the width of the rectangle is x. The length of the rectangle is then 2x + 6. We can use the Pythagorean theorem to set up an equation using the diagonal and the sides of the rectangle. The Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
Using the Pythagorean theorem, we have:
x^2 + (2x + 6)^2 = 15^2
Simplifying and solving this equation will give us the value of x, which is the width of the rectangle. We can then calculate the length of the rectangle by substituting the value of x into the expression 2x + 6.
Let's solve the equation:
x^2 + (2x + 6)^2 = 15^2
Expanding the equation and simplifying:
x^2 + 4x^2 + 24x + 36 = 225
Combining like terms:
5x^2 + 24x + 36 = 225
Moving 225 to the other side of the equation:
5x^2 + 24x + 36 - 225 = 0
Simplifying further:
5x^2 + 24x - 189 = 0
Now we can solve this quadratic equation for x. We can factor it or use the quadratic formula.
By factoring, we find that x = -9 or x = 7.8. Since we are dealing with dimensions, we can ignore the negative value and take x = 7.8 centimeters as the width of the rectangle.
The length would then be 2(7.8) + 6 = 22.6 centimeters. So, the dimensions of the rectangle should be a width of 7.8 centimeters and a length of 22.6 centimeters.

B) Both statements could be correct. RST could be the result of two translations of ABC. TSR could be the result of a rotation and a translation of ABC.
C) Both statements could be correct. RST could be the result of two translations of ABC. TSR could be the result of a reflection and a translation of ABC.
D) Kelley’s statement is correct. TSR is the same orientation, shape, and size as ABC.
Answer:
C) Both statements could be correct. RST could be the result of two translations of ABC. TSR could be the result of a reflection and a translation of ABC.
Step-by-step explanation:
When naming congruent shapes, the orders of the congruent vertex letters need to be the same.
Since these are isosceles triangles, the base angles are the same:
m∠R = m∠T = m∠A = m∠C
Therefore the congruency statement can be written two different ways.
ΔABC ≅ ΔRST
ΔABC ≅ ΔTSR
Both statements could be correct.
Choosing between B) and C):
To move ΔABC to where ΔRST or ΔTSR is, you could either:
i) Translate 6 units to the left, and translate 3 units down
ii) Reflect across the y-axis, and translate 3 units down
It can be the result of two translations or a reflection and a translation.
In the result, the base side RT is on the bottom of the shape, like side AC. If you rotated the shape, the base side would not be on the bottom. Therefore B) is incorrect.

What is the volume of a cylinder, in cubic m, with a height of 9m and a base diameter of 12m? Round to the nearest tenths place.
The requried volume of the cylinder is approximately 1017.9 cubic meters.
What is the volume of a cylinder?The volume of a cylinder can be calculated using the formula:
Volume = π * (diameter/2)² * height
where π (pi) is a mathematical constant approximately equal to 3.14159, diameter is the base diameter of the cylinder, and height is the height of the cylinder.
In this case, the height is 9m and the base diameter is 12m. We need to first calculate the radius, which is half of the diameter:
Radius = diameter/2 = 12m/2 = 6m
Now we can substitute the values into the formula and calculate the volume:
Volume = π * (6m)² * 9m
Volume ≈ 1017.88 cubic meters
Rounding to the nearest tenth place, the volume of the cylinder is approximately 1017.9 cubic meters.

Final answer:
The volume of a cylinder with a height of 9m and a base diameter of 12m is approximately 9160.9 cubic meters when rounded to the nearest tenth.
Explanation:
The student is asking for the volume of a cylinder with a given height and base diameter, which is a common problem in mathematics related to geometry and measurements. To find the volume, we use the formula for the volume of a cylinder V = πr²h, where V is the volume, r is the radius of the base, and h is the height of the cylinder. Given that the diameter is 12 meters, the radius (r) is half of that, which is 6 meters. We then substitute these values into the formula:
V = π(6m)²(9m)
V = 3.1416 × 36m² × 9m
V = 3.1416 × 324m² × 9m
V = π × 2916m³
V = 9160.88m³
After calculating, we round the volume to the nearest tenths place, obtaining V ≈ 9160.9m³.

A customer at a store paid $64 for 3 large candles and 4 small candles. At the same store, a second customer paid $4 more than the first customer for 1 large candle and 8 small candles. The price of each large candle is the same, and the price of each small candle is the same. Which system of equations can be used to find the price in dollars of each large candle, x, and each small candle, y?
system of equations can be used to find the price in dollars of each large candle, x, and each small candle, y is [tex]x+8y=68[/tex] and [tex]3x+4y=64[/tex] .
Step-by-step explanation:
Here we have , A customer at a store paid $64 for 3 large candles and 4 small candles. At the same store, a second customer paid $4 more than the first customer for 1 large candle and 8 small candles. The price of each large candle is the same, and the price of each small candle is the same. We need to find Which system of equations can be used to find the price in dollars of each large candle, x, and each small candle, y . Let's find out:
Let the price in dollars of each large candle, x, and each small candle, y .So
A customer at a store paid $64 for 3 large candles and 4 small candles
Equation is :
⇒ [tex]3x+4y=64[/tex] .....(1)
At the same store, a second customer paid $4 more than the first customer for 1 large candle and 8 small candles.
Equation is :
⇒ [tex]x+8y=68[/tex] .......(2)
3(2)-(1) i.e.
⇒ [tex]3(x+8y)-(3x+4y)=68(3)-64[/tex]
⇒ [tex]20y=140[/tex]
⇒ [tex]y=7[/tex]
So , [tex]x+8y=68[/tex]
⇒ [tex]x+8(7)=68[/tex]
⇒ [tex]x=12[/tex]
Therefore , system of equations can be used to find the price in dollars of each large candle, x, and each small candle, y is [tex]x+8y=68[/tex] and [tex]3x+4y=64[/tex] .
The system of equations that can be used to find the price in dollars of each large candle, x, and each small candle, y are;
3x + 4y = 64
x + 8y = 68
$64 was paid for 3 large candles and 4 small candles. If large candle cost x and small candle cost y, then;
3x + 4y = 64
Now, a second customer paid $4 more than the first customer for 1 large candle and 8 small candles.
Thus;
x + 8y = 64 + 4
x + 8y = 68
Thus, the system of equations that can be used to find the price in dollars of each large candle, x, and each small candle, y is;
3x + 4y = 64
x + 8y = 68

A family has two cars during one particular week the first car consume 25 gallons of gas and the second consumed 15 gallons of gas the two cars Drove a combined total of 1075 miles and the sum of the fuel efficiencies was 55 miles per gallon what were the fuel efficiencies of each of the cars that week?
Answer: the efficiency of the first car is 25 miles per gallon.
the efficiency of the second car is 30 miles per gallon.
Step-by-step explanation:
Let x represent the efficiency of the first car.
Let y represent the efficiency of the second car.
Distance = car efficiency × number of gallons.
The first car consume 25 gallons of gas and the second consumed 15 gallons of gas. The two cars Drove a combined total of 1075 miles. It means that
25x + 15y = 1075- - - - - - - - - - -1
The sum of the fuel efficiencies was 55 miles per gallon. It means that
x + y = 55
Substituting x = 55 - y into equation 1, it becomes
25(55 - y) + 15y = 1075
1375 - 25y + 15y = 1075
- 25y + 15y = 1075 - 1375
- 10y = - 300
y = - 300/-10
y = 30
x = 55 - y = 55 - 30
x = 25
