A) Draw a number line from 0 to 2. Then draw and label the points 2 and 0.2. B) use the number line to explain why 2 is 10 times the value of 0.2
Answers
Answer:
See attachment
Step-by-step explanation:
A) We draw the number line as shown in the attachment with intervals of 0.2 from 0 to 2.
B) Observe that, from 0 to 0.2 you move one units to get to 0.2.
From 0 to 2, on the number line with intervals of 0.2, you move 10 units from 0.
This means that:
[tex]2 = 0.2 + 0.2 + 0.2 + 0.2 + 0.2 + 0.2 + 0.2 + 0.2 + 0.2 + 0.2[/tex]
This gives us:
[tex]2 = 0.2(1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1)[/tex]
Then finally we have:
[tex]2 = 0.2(10)[/tex]
By the commutative property of multiplication:
[tex]2 = 10 \times 0.2[/tex]

Find the area of a regular octagon with a side length of 10 cm. Round to the nearest tenth.
Answers
The question keeps telling me to STOP! Never mind.
The octagon is 8 isosceles triangles. Each has common side r and base 10. The central angle is 360/8 = 45°. By the Law of cosines,
10² = r² + r² - 2 r² cos 45° = 2r²(1 - √2/2) = r²(2-√2)
r² = 100/(2-√2)
The area of a triangle with sides a,b and included angle C is (1/2)ab sin C. Our 8 octagon isosceles triangles each have sides r and r and included angle 45° so our total area, 8 triangles, is
A = 8(1/2) r² sin 45° = (400/(2-√2)) (√2/2) × (2+√2)/(2+√2) = 200(1+√2)
A ≈482.84271
Answer: 482.8 sq cm
Final answer:
To find the area of a regular octagon with a side length of 10 cm, use the formula: Area = 2 * (1 + √2) * side length². Substitute the given side length and round the answer to the nearest tenth.
Explanation:
To find the area of a regular octagon with a side length of 10 cm, we can use the formula:
Area = 2 * (1 + √2) * side length²
Substituting the given side length into the formula:
Area = 2 * (1 + √2) * (10)²
Area = 2 * (1 + √2) * 100
Area ≈ 414.2 cm² (rounded to the nearest tenth)
After further computation, the area approximates 414.2 cm², rounded to the nearest tenth. This formula captures the geometric intricacies of a regular octagon, demonstrating a concise method to calculate its area based on the given side length. This formula encapsulates the unique characteristics of a regular octagon, providing a streamlined approach to computing its area and showcasing the elegant relationship between side length and the polygon's spatial coverage.

A survey finds customers are charged incorrectly for 4 out of every 10 items. suppose a customer purchases 11 items. find the probability that the customer is charged incorrectly on at least 3 items. the probability that the customer is charged incorrectly on at least 3 items is nothing
Answers
Answer:
The probability that the customer is charged incorrectly on at least 3 items is 88.11%
Step-by-step explanation:
For each item, there are only two possible outcomes. Either they are charged correctly, or they are not. The probability of an item being charged incorrectly is independent of other items. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
A survey finds customers are charged incorrectly for 4 out of every 10 items.
This means that [tex]p = \frac{4}{10} = 0.4[/tex]
Suppose a customer purchases 11 items.
This means that [tex]n = 11[/tex]
Find the probability that the customer is charged incorrectly on at least 3 items.
Either he is charged incorrectly on less than 3 items, or at least 3. The sum of the probabilities of these events is decimal 1. So
[tex]P(X < 3) + P(X \geq 3) = 1[/tex]
We want [tex]P(X \geq 3)[/tex]. So
[tex]P(X \geq 3) = 1 - P(X < 3)[/tex]
In which
[tex]P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2)[/tex]
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{11,0}.(0.4)^{0}.(0.6)^{11} = 0.0036[/tex]
[tex]P(X = 1) = C_{11,1}.(0.4)^{1}.(0.6)^{10} = 0.0266[/tex]
[tex]P(X = 2) = C_{11,2}.(0.4)^{2}.(0.6)^{9} = 0.0887[/tex]
[tex]P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2) = 0.0036 + 0.0266 + 0.0887 = 0.1189[/tex]
[tex]P(X \geq 3) = 1 - P(X < 3) = 1 - 0.1189 = 0.8811[/tex]
88.11% probability that the customer is charged incorrectly on at least 3 items
Final answer:
To determine the probability that a customer is charged incorrectly on at least three items out of 11, we use the binomial probability formula, summing up probabilities from 3 to 11 incorrect charges.
Explanation:
Probability of Being Charged Incorrectly on At Least 3 Items
To solve the problem of finding the probability that a customer is charged incorrectly on at least three items when they purchase 11 items, we use the binomial probability formula. Given that the probability of being charged incorrectly for one item is 0.4 (4 out of 10), we denote this as p=0.4. The probability of being charged correctly is q=1-p=0.6. The total number of items, n, is 11.
The binomial probability P(X ≥ k) for at least k successes out of n trials is calculated by summing up the probabilities of having k, k+1,..., n successes.
To find P(X ≥ 3) we calculate:
P(X=3) where X represents the number of items charged incorrectlyContinue similarly to find P(X=4), P(X=5), ..., P(X=11)Sum these probabilities to get P(X ≥ 3)This calculation involves using the binomial formula which is:
P(X=k) = C(n,k) × p^k × q^(n-k)
Where C(n,k) is the combination of n items taken k at a time.
Once each individual probability is calculated, add them up to find the total probability of being charged incorrectly on at least 3 items. Remember, it is not possible to have a probability greater than 1, as this would imply certainty beyond the maximum possible (100%).

Suppose you order an ice cream cone that holds 157 cubic centimeters of your favorite flavor. You calculate the height of your cone is 12cm. Find the diameter of your ice cream cone. (Use π≈3.14, and round to the nearest hundredth.)
Answers
Answer: Diameter = 7.06 cm
Step-by-step explanation:
The formula for determining the volume of a cone is expressed as
Volume = 1/3πr²h
Where
h represents the height of the cone
r represents the radius of the cone
π is a constant whose value is 3.14
From the information given
Volume = 157 cubic centimeters
Height = 12cm
Therefore,
157 = 1/3 × 3.14 × r² × 12
157 =12.56r²
r² = 157/12.56
r² = 12.5
Taking square root of both sides of the equation, it becomes
r = √12.5
r = 3.53 cm
Diameter = 2 × radius = 2 × 3.53
Diameter = 7.06 cm
>What would the new point be if you rotated the point (4,9) 180°about the origin?
Answers
Answer:(-4,-9)
Step-by-step explanation:
Final answer:
After rotating the point (4,9) 180° about the origin, the new coordinates would be (-4, -9).
Explanation:
To determine the new coordinates of a point after a 180° rotation about the origin, you can apply the rules of rotation in a coordinate plane.
For a 180° rotation, each coordinate (x, y) becomes (-x, -y).
Therefore, if we rotate the point (4,9) 180° about the origin, we change the sign of both coordinates.
The new point after rotation would be (-4, -9).

URGENT PLZZZ!!!! for the given situation identify the independent and dependent variables and then find a reasonable domain and range of values. Listed below will be four statements that relate to the given situation. She’s the statement that would have to be false given the situation and it’s parameters.
chain owns a scooter that can travel 65 miles per gallon of gasoline. her tank holds 2.5 gallons. She’s planning on taking a shopping trip around her city.
here are the statements
1) The range is 0 miles to 162.5 miles
2) The dependent variable is how many hours she will spend shopping in the stores
3) The independent variable is how much gasoline she’ll use
4) The domain is 2.5 gallons to 0 gallons
Answers
Answer:
2
Step-by-step explanation:
the dependent variable is the amount of time she spends driving around.
Final answer:
In the scenario, the independent variable is the amount of gasoline used, and the dependent variable is the distance traveled. The domain is 0 to 2.5 gallons and the range is 0 to 162.5 miles, hence statement 2 is false regarding the dependent variable.
Explanation:
For the given situation, the independent variable is the amount of gasoline she'll use. This is because it is the variable that can be changed freely and does not depend on the other variables in the situation. In contrast, the dependent variable is the distance that can be traveled with the scooter, as it depends on the amount of gasoline used.
The domain for this situation would be the amount of gasoline available for use, which is between 0 gallons (an empty tank) and 2.5 gallons (a full tank). The range would be the distance the scooter can travel on that gasoline, from 0 miles (no gasoline) to 162.5 miles (2.5 gallons at 65 miles per gallon).
Therefore, statement 2 "The dependent variable is how many hours she will spend shopping in the stores" would have to be false given the situation and its parameters, because the dependent variable is actually the distance that can be traveled, not the time spent shopping.

Answers
Answer: [tex]r=3[/tex]
Simplify both sides of the equation
[tex]r+12/5=27/5[/tex]
Subtract 12/5 from both sides
[tex]r+12/5-12/5=27/5-12/5[/tex]
[tex]r=3[/tex]
The solution to the equation 2 2/5 + r = 5 2/5 is r = 3, which is found by subtracting 2 2/5 (converted to 12/5) from 5 2/5 (converted to 27/5).
Explanation:The solution to the equation 2 2/5 + r = 5 2/5 is found by isolating the variable r.
First, convert the mixed numbers to improper fractions.
We have 12/5 (equivalent to 2 2/5) and 27/5 (equivalent to 5 2/5).
Now, subtract 12/5 from both sides of the equation to get r on one side:
27/5 - 12/5 = rAfter subtraction, we find that:
r = 15/5r = 3Thus, the solution to the equation is r = 3.
Diane made a design using only squares she shaded the inner square and outer region find the total area that is shaded explain how you found your answer

The total shaded area is four times the area of the inner shaded square. If the side length of the inner square is [tex]\(a\) units, the total shaded area is \(4a^2\)[/tex]square units. This is derived by adding the area of the inner square to the outer shaded region's area.
To find the total area shaded, we need to calculate the combined area of the inner shaded square and the outer shaded region.
Let's denote the side length of the inner square as a units and the side length of the outer square as b units. Since the design consists only of squares, the outer square will have sides twice as long as the inner square, so [tex]\(b = 2a\).[/tex]
The area of the inner shaded square is [tex]\(a^2\)[/tex] square units, and the area of the outer shaded region is the difference between the area of the outer square and the area of the inner square, which is[tex]\(b^2 - a^2\).[/tex]
Substituting [tex]\(b = 2a\), we get the area of the outer shaded region as \((2a)^2 - a^2 = 4a^2 - a^2 = 3a^2\)[/tex] square units.
Therefore, the total shaded area is the sum of the area of the inner square and the area of the outer shaded region: [tex]\(a^2 + 3a^2 = 4a^2\).[/tex]

A swimming pool is to be drained. The pool is shaped like a rectangular prism with length 30 feet, wide 18 ft, and depth 4ft. Suppose water is pumped out of the pool at a rate of 216ft3 per hour. If the pool starts completely full, how many hours does it take to empty the pool?
Answers
Answer: it will take 9 hours to empty the pool.
Step-by-step explanation:
The pool is shaped like a rectangular prism with length 30 feet, wide 18 ft, and depth 4ft. It means that when the pool is full, its volume is
30 × 18 × 4 = 2160 ft³
If water is pumped out of the pool at a rate of 216ft3 per hour, then the rate at which the water in the pool is decreasing is in arithmetic progression. The formula for determining the nth term of an arithmetic sequence is expressed as
Tn = a + d(n - 1)
Where
a represents the first term of the sequence(initial amount of water in the pool when completely full).
d represents the common difference(rate at which it is being pumped out)
n represents the number of terms(hours) in the sequence.
From the information given,
a = 2160 degrees
d = - 216 ft3
Tn = 0(the final volume would be zero)
We want to determine the number of terms(hours) for which Tn would be zero. Therefore,
0 = 2160 - 216 (n - 1)
2160 = 216(n - 1) = 216n + 216
216n = 2160 - 216
216n = 1944
n = 1944/216
n = 9
Step-by-step explanation:
Answer: it will take 9 hours to empty the pool. Step-by-step explanation: The pool is shaped like a rectangular prism with length 30 feet, wide 18 ft, and depth 4ft. It means that when the pool is full, its volume is 30 x 18 x 4 = 2160 ft3 If water is pumped out of the pool at a rate of 216ft3 per hour, then the rate at which the water in the pool is decreasing is in arithmetic progression.

We want to determine the number of terms(hours) for which Tn would be zero. Therefore,
O = 2160 - 216 (n - 1) 2160 = 216(n - 1) = 216n + 216 216n = 2160 - 216 216n = 1944 %3D n = 1944/216 n = 9

the circumference of a circle c with a radius of r units is approximately given by the linear equation C=6.3r. Find two solutions of this function. Explain the solutions.
Answers
Final answer:
The circumference of a circle with a given radius can be calculated using the linear equation C = 6.3r. Two examples of solutions to this equation are C = 12.6 units when r = 2, and C = 31.5 units when r = 5.
Explanation:
The circumference of a circle with a radius of r units is given by the linear equation C = 6.3r. To find two solutions of this function, we can substitute different values for r into the equation.
For example, if we let r = 2, then the circumference C is calculated as C = 6.3 * 2 = 12.6 units.
Another solution is when r = 5. In this case, the circumference C is C = 6.3 * 5 = 31.5 units.

Joaquin's family is planning to drive from Sandpoint to Grangeville. They have a map on which 1 inch = 62 miles. Joaquin measures the distance on
the map to be almost 4 inches.
If Joaquin's mother drives an average of 50 miles per hour, about how long will their trip take without any stops?
Answers
Answer: If you round it, should be about 5 hours.
The actual distance from Sandpoint to Grangeville would be 248 miles. If Joaquin's mother drives an average of 50 miles per hour, the trip will take almost 5 hours without any stops.
Explanation:To solve this problem, we need to calculate the actual distance and then the time it will take. As it is mentioned that 1 inch on the map represents 62 miles in reality, if Joaquin measures the distance on the map to be 4 inches, then the actual distance will be 4 inches * 62 miles per inch = 248 miles. Then, if Joaquin's mother drives at a speed of 50 miles per hour, the time it will take to travel that distance can be calculated by dividing the total distance by the speed. So, 248 miles / 50 mph = 4.96 hours. It means that their trip will take almost 5 hours without any stops.

Here,
Total letters = 10
Total a and n = 2 and 3
The probability is given as = 2 / 10 + 3 / 10
= 5/10 = 1/2 = 0.5
Thus, the required probability of the selected letter was either an a or an n is 0.5.

Charles owns a hardware store. He put hammers and nails on sale last weekend. His first customer bought 3 hammers and 16 nails for $22.96. His last customer bought 2 hammers and 20 nails for $16.80. What was the sale price for hammers and nails?
Answers
Answer: the sale price of one hammer is $6.8
the sale price of one nail is $0.16
Step-by-step explanation:
Let x represent the sale price of one hammer.
Let y represent the sale price of one nail.
His first customer bought 3 hammers and 16 nails for $22.96. It means that
3x + 16y = 22.96- - - - - - - - -1
His last customer bought 2 hammers and 20 nails for $16.80. It means that
2x + 20y = 16.8- - - - - - - - - 2
Multiplying equation 1 by 2 and equation 2 by 3, it becomes
6x + 32y = 45.92
6x + 60y = 50.4
Subtracting, it becomes
- 28y = - 4.48
y = - 4.48/- 28
y = 0.16
Substituting y = 0.16 into equation 2, it becomes
2x + 20 × 0.16 = 16.8
2x + 3.2 = 16.8
2x = 16.8 - 3.2
2x = 13.6
x = 13.6/2
x = 6.8
What is the equation of the line with the same slope as the equation x-4y=3 and the y-intercept(0,-8)?
Answers
Answer:
y = 1/4x -8
Step-by-step explanation:
First find the slope of the line
x-4y =3
Subtract x from each side
x-4y -x = -x+3
-4y = -x+3
Divide each side by -4
-4y/-4 = -x/-4 +3/-4
y = 1/4 x -3/4
This is in the form y= mx+b where the slope is m and the y intercept is b
The slope is 1/4
We want the same slope
y = 1/4x +b
we know the y intercept is -8
y = 1/4x -8
