Answer:
Part 1) The measure of angle x is 24°
Part 2) The measure of angle y is 66°
Step-by-step explanation:
step 1
Find the measure of angle m∠IKL
we know that
m∠JKI+m∠IKL=180° ----> supplementary angles (form a linear pair)
we have
m∠JKI=48°
substitute
48°+m∠IKL=180°
m∠IKL=180°-48°=132°
step 2
Find the measure of angle x
we know that
The triangle IKL is an isosceles triangle
so
m∠KIL=m∠KLI=x
Remember that
The sum of the interior angles of a triangle must be equal to 180 degrees
m∠IKL+2x=180°
132°+2x=180°
2x=180°-132°
x=24°
step 3
In the right triangle JIL
Angles x and y are complementary
so
x+y=90°
24°+y=90°
y=90°-24°
y=66°
Find X. Round to the nearest tenth if necessary.
Answer:
x = 9
Step-by-step explanation:
When 2 chords intersect inside a circle then the product of the measures of the parts of one chord is equal to the product of the measures of the parts of the other chord, that is
2 × x = 3 × 6, that is
2x = 18 ( divide both sides by 2 )
x = 9
What is the volume of the prism below 4 height length 18 9width
The volume of the prism is [tex]\(V = 648 \, \text{cubic units}\).[/tex]
The formula for the volume (V) of a rectangular prism is given by [tex]\(V = lwh\),[/tex] where (l) is the length, (w) is the width, and (h) is the height. In this case, the provided dimensions are length (l = 18), width (w = 9), and height (h = 4). Substituting these values into the formula: [tex]\[ V = 18 \times 9 \times 4 = 648 \, \text{cubic units}. \][/tex] Therefore, the volume of the prism is [tex]\(648 \, \text{cubic units}\).[/tex]
Understanding the concept of volume in three-dimensional geometry is vital. The formula [tex]\(V = lwh\)[/tex] reflects the relationship between the length, width, and height of a rectangular prism. Multiplying these dimensions provides the total space enclosed by the prism in cubic units. In this instance, with a length of 18 units, a width of 9 units, and a height of 4 units, the volume calculation yields [tex]\(648 \, \text{cubic units}\),[/tex] representing the spatial capacity of the given prism.
Calculating the volume of prisms is a fundamental skill in geometry and has practical applications in various fields, including architecture and engineering. This calculation allows us to quantify the amount of space a three-dimensional object occupies, providing essential information for design and analysis. In this case, the resulting volume, [tex]\(648 \, \text{cubic units}\),[/tex] represents the capacity of the rectangular prism specified by the given dimensions.
What are the zeros of Ax) = x2 - 12x + 36?
O A. x= -6 and x = 6
O B. x=-6 only
O c. x = 6 only
O D. x=-4 and x = 9
SUBMIT
Answer:
The correct option is C
Step-by-step explanation:
x2 - 12x + 36
The coefficient of 1st term will be multiplied by the constant:
1*36 = 36
Now find two numbers whose product is 36 and whose addition is 12.
6*6 = 36
6+6 =12
Now break the middle term:
x^2-6x-6x+36 = 0
Now group the terms:
(x^2-6x) - (6x-36) = 0
Now take common of each group:
x(x-6)-6(x-6) = 0
(x-6) (x-6) =0
(x-6)=0 , (x-6) =0
x-6=0 , x-6=0
x=0+6 , x=0+6
x=6 , x=6
Thus the correct option is C. x=6 only....
A brand new motorcycle gets 70 miles per gallon of gas. If the motorcycle drives 520 miles before running out of gas, how much gas started in the tank? Write you answer as a mixed number.
Answer:
[tex]x=7 \frac{3}{7}[/tex] gallons
Step-by-step explanation:
So we are given:
70 miles -> 1 gallon is used.
520 miles -> x gallons is used.
Set up a proportional to solve.
I lined up everything already above:
[tex]\frac{70}{520}=\frac{1}{x}[/tex]
Cross multiply:
[tex]70(x)=520(1)[/tex]
[tex]70x=520[/tex]
Divide both sides by 70:
[tex]x=\frac{520}{70}[/tex]
Reduce the fraction (divide top and bottom by 10):
[tex]x=\frac{52}{7}[/tex]
How many 7's are in 52? 7 because 7(7)=49
How much is left over after seven 7's go into 52? 52-49=3
So the answer as a mixed fraction is:
[tex]x=7 \frac{3}{7}[/tex]
To find out how much gas was in the motorcycle's tank, divide the total distance driven by the fuel efficiency. In this case, 520 miles / 70 miles per gallon equals 7 2/5 gallons of gas.
To determine how much gas started in the tank of the motorcycle that gets 70 miles per gallon and drove 520 miles before running out of gas, we use the formula:
Calculate the number of gallons used by dividing the total distance driven by the mileage per gallon. This gives us the formula: Gallons Used = Total Miles Driven / Mileage (Miles per Gallon).Divide the total miles driven, which is 520 miles, by the mileage per gallon, which is 70 miles per gallon.The result is 520 miles / 70 miles per gallon = 7.4285714286 gallons.To express this as a mixed number, we take the integer part, which is 7 gallons, and then write the decimal part as a fraction. The decimal part is approximately 0.4286, which can be rounded to 4\/10 or simplified to 2/5. So the mixed number is 7 2/5 gallons.derivative of f(x)=5.2x+2.3
Answer:
5.2
Step-by-step explanation:
Since you have a linear function, asking for derivative is equivalent to asking for the slope.
The slope of y=5.2x+2.3 is 5.2 so the derivative is 5.2 .
However, if you really want to use the definition of derivative, you may.
That is, [tex]\lim_{h \rightarrow 0} \frac{f(x+h)-f(x)}{h}[/tex].
We know [tex]f(x)=5.2x+2.3[/tex] so [tex]f(x+h)=5.2(x+h)+2.3[/tex]. All I did was replace any x in the 5.2x+2.3 with (x+h) to obtain f(x+h).
Let's plug it into our definition:
[tex]\lim_{h \rightarrow 0} \frac{f(x+h)-f(x)}{h}[/tex]
[tex]\lim_{h \rightarrow 0} \frac{[5.2(x+h)+2.3]-[5.2x+2.3]}{h}[/tex]
Now we need to do some distributing. I see I need this distributive property both for the 5.2(x+h) and the -[5.2x+2.3].
[tex]\lim_{h \rightarrow 0} \frac{5.2x+5.2h+2.3-5.2x-2.3}{h}[/tex]
There are some like terms to combine in the numerator. The cool thing is they are opposites and when you add opposites you get 0.
[tex]\lim_{h \rightarrow 0} \frac{5.2h}{h}[/tex]
There is a common factor in the numerator and denominator. h/h=1.
[tex]\lim_{h \rightarrow 0}5.2[/tex]
5.2
[tex]f(x)=5.2x+2.3\\f'(x)=5.2[/tex]
If rs 500 amounts to Rs 725 at 9% simple interest in sometime ,what will Rs 600amount to at 11% in same time?
To solve the student's question, we calculated the time period from the initial amount and interest rate, then used that to determine the amount that Rs 600 would become at an 11% interest rate over the same period, which is Rs 930.
Explanation:The essence of the question revolves around the concept of calculating the future amount of money based on the principal, the rate of interest, and the time for which the money is lent or invested. In the given scenario, we have a principal of Rs 500 which, at a 9% simple interest rate, amounts to Rs 725 over a certain period.
To find the equivalent amount for Rs 600 at an 11% interest rate over the same period, we need to first understand the amount of interest accrued in the first situation and use its proportion to calculate the second.
The formula for simple interest is Interest = Principal × rate × time.
First, let's calculate the interest earned on the initial Rs 500:
Amount = Principal + InterestRs 725 = Rs 500 + InterestInterest = Rs 725 - Rs 500Interest = Rs 225Now, we can calculate the time period using the simple interest formula:
Interest = Principal × rate × timeRs 225 = Rs 500 × 0.09 × timeTime = Rs 225 / (Rs 500 × 0.09)Time = 5 yearsKnowing the time period, we can find the amount that Rs 600 would amount to at an 11% interest rate over the same period:
Interest = Rs 600 × 0.11 × 5 yearsInterest = Rs 330Amount = Principal + InterestAmount = Rs 600 + Rs 330Amount = Rs 930So, Rs 600 will amount to Rs 930 at an 11% simple interest rate over the same time period of 5 years.
A recipe for muffins calls for 1/2 quart of buttermilk, 1/3 quart of skim milk, and 1/16 quart of oil. How many total quarts of liquid ingredients does the recipe call for?
To find the total quarts of liquid ingredients for the muffin recipe, add together 1/2 quart of buttermilk, 1/3 quart of skim milk, and 1/16 quart of oil, resulting in 43/48 quarts in total after converting to a common denominator and summing up.
The question asks how many total quarts of liquid ingredients are called for in a muffin recipe, which includes 1/2 quart of buttermilk, 1/3 quart of skim milk, and 1/16 quart of oil. To find the total, you need to add these measurements together.
Adding the fractions:
1/2 quart of buttermilk1/3 quart of skim milk1/16 quart of oilFirst, find a common denominator, which would be 48 in this case. Converting each fraction:
24/48 (for 1/2 quart)16/48 (for 1/3 quart)3/48 (for 1/16 quart)Adding these fractions together gives us 43/48 quarts as the total amount of liquid ingredients needed for the recipe.
Which equations and/or functions represent the graphed line? Select three options.
f(x)=1/5x-4
f(x)=1/2x+2
f(x)=1/2x+1
y-3=1/2(x-2)
y-1=1/2(x+2)
Answer:
f(x) = 1/2x + 2
y - 3 = 1/2(x - 2)
y - 1 = 0.5(x + 2)
Step-by-step explanation:
The equations that represent the graphed line are f(x) = 1/2x + 2, f(x) = 1/2x + 1, and y - 1 = 1/2(x + 2).
Explanation:The equation of a line in slope-intercept form is given by y = mx + b, where m is the slope of the line and b is the y-intercept. In the given options, the equations that represent the graphed line are:
f(x) = 1/2x + 2f(x) = 1/2x + 1y - 1 = 1/2(x + 2)These equations have the same slope and y-intercept as the graphed line.
What is the slope-intercept form of the equation of the line graphed in the figure?
A. y = 5⁄3x + 1
B. y = –5⁄3x – 1
C. y = –3⁄5x + 1
D. y = 3⁄5x + 1
Answer:
D
Step-by-step explanation:
It crosses the y-axis at y=1 so the y-intercept is b=1.
The slope is count straight up from (-5,-2) to you are on the same horizontal level as (5,4). The rise is 6
Once you get the same horizontal level as (5,4), you will count straight over to you get to (5,4). The run is 10.
Slope=rise/run=6/10=3/5.
Or you could find slope by using the slope formula. I like to line up two pairs of points and subtract then put 2nd difference over first difference. Like so,
(5,4)
-(-5,-2)
----------
10 6
So the slope is 6/10 or 3/5 after reducing.
Slope-intercept form of a line is y=mx+b
Plug in m=3/5 and b=1
y=3/5 x +1
So the answer is D.

Answer: The list price of the car was $ 23655.91.
Step-by-step explanation: Given that Emily bought a new car for $22000 and she paid 93% of the list price.
We are to find the list price of the car.
Let $ x denote the list price of the car.
Then, according to the given information, we have
[tex]93\%\times x=22000\\\\\\\Rightarrow \dfrac{93}{100}\times x=22000\\\\\Rightarrow 93x=22000\times100\\\\\Rightarrow 93x=2200000\\\\\Rightarrow x=\dfrac{2200000}{93}\\\\\Rightarrow x=23655.91.[/tex]
Thus, the list price of the car was $ 23655.91.

u want to leave a 15% tip on a $33 meal. What is the total cost for the night?
Answer: The total cost would be 37.95
Step-by-step explanation:
The total cost for the night, including a 15% tip on a $33 meal, is $37.95.
Explanation:To calculate the total cost for the night, we need to add the meal cost and the tip. For a $33 meal, a 15% tip would be calculated using the formula tip = meal cost x tip percentage/ 100. In this case, tip = $33 x 15/100= $4.95. Therefore, the total cost for the night (meal cost + tip) would be $33 + $4.95 = $37.95.

Ben and Arnoldo are sharing snacks. They have peanut treats and coconut treats. Ben ate 2 of the peanut treats and 4 of the coconut treats for a total of 160 calories. Arnoldo ate 3 of the peanut treats and 2 of the coconut treats for a total of 140 calories. They wrote the system below to represent the number of calories there are in the two types of treats.
Answer:
The number of calories in a peanut treat is 30.
The number of calories in a coconut treat is 25.
Step-by-step explanation:
So we have Ben ate 2 peanut treats (let p represent the calories in each peanut treat) and 4 coconut treats (let c represent the calories in each coconut treat). The sum of those calories is 160.
This is the equation for Ben:
2p+4c=160
I'm going to use the same representation here. p for the number of calories in each peanut treat and c for the number of calories in each coconut treat.
Arnold ate 3 p's and 2 c's for a sum of 140 calories:
Alrnoldo's equation is:
3p+2c=140
So we have the system:
2p+4c=160
3p+2c=140
I'm going to divide the first equation by 2 because each term is divisible by 2:
p+2c=80
3p+2c=140
This system is setup for elimination because the equations are in the same form and the second column have the same variable expression, 2c. So we are going to subtract to eliminate the variable c, that is 2c-2c=0.
p+2c=80
3p+2c=140
---------------------Subtract!
-2p+0=-60
-2p =-60
Divide both sides by -2:
p =30
So if p=30 and p+2c=80 , then 30+2c=80.
So let's solve:
30+2c=80 for c
Subtract 30 on both sides:
2c=50
Divide both sides by 2:
c=25
The number of calories in a peanut treat is 30.
The number of calories in a coconut treat is 25.

Write an equation for a circle with a diameter that has endpoints at (-10, 1) and (-8, 5). Round to the nearest tenth if necessary.
Answer:
The equation is (x+9)^2 + (y-3)^2 = 5
Step-by-step explanation:
The standard form for the equation of a circle is:
(x−h)^2+(y−k)^2=r2
The center of the circle is the midpoint of the diameter.
So the midpoint of the diameter at (-10, 1) and (-8, 5) can be determined as:
(-10 +(-8))/2 , (1+5)/2
= -10-8/2, 1+5/2
= -18/2 , 6/2
= -9 , 3
Thus(-9,3) is the center of the circle.
Now we will use the distance formula to find the radius of the circle.
r^2=(-10-(-9))^2 + (1-3)^2
r^2=(-10+9)^2 +(-2)^2
r^2=(-1)^2 + (-2)^2
r^2=1 + 4
r^2= 5
Take square root at both sides.
√r^2= √5
r=√5
Now put the values in the 1st equation.
(x−h)^2+(y−k)^2=r2
where h = -9, k =3 and r = √5
(x-(-9))^2 + (y-3)^2= (√5)^2
(x+9)^2 + (y-3)^2 = 5
Thus the equation is (x+9)^2 + (y-3)^2 = 5 ....

Step-by-step explanation:
no it is not because if 3 maps on 2, then it cannot map on -2 at the same time
A relation is considered a function if each input has only one output. The given set contains the input '3' with two different outputs '2' and '-2', therefore, it is not a function.
Explanation:In mathematics, a relationship is considered a function if for every input there is only one output. In other words, no two pairs should have the same first element yet different second elements.
If we look at the set of ordered pairs provided, we have {(3, 2), (3, -2), (1, -4), (-1, 2)}. We can see that the input '3' corresponds to both '2' and '-2'. Since there are two outputs for the same input, we can determine that this relation is not a function.
