If why varies with the square of x and Y equals 24 when x equals 10 then the constant of proportionality is ____, and the value of y when x equals 20 is ____. Assume x is greater than or equal to 0. Select two answers
Answer:
Step-by-step explanation:
y varies with the square of x:
y = kx²
y equals 24 when x equals 10
24 = k·10²
constant of proportionality k = 0.24
when x = 20, y = 0.24·20² = 96

You work as an assistant to a carpenter who designed the tabletop below. He tells you that each shape is a right triangle, and each is the same size. You now need to calculate the area of one triangle so that you can begin building the tabletop. What is the area of each triangle in square inches? 28 1/4" and 20"
Answer:
282.5 inches squared
Step-by-step explanation:
A triangle is half the area of a square.
So we will solve the area as if we were finding the area for a square, and then we halve the result.
Length multiply by height to get the area:
28.25 × 20 = 565 inches squared
Now, half the answer to get the area of the triangle:
565/2=282.5 inches squared

( I got -3 and I don't think I got it right. Could somebody also explain how they got it? Thank you!)
Answer:
Conversion a mixed number 2 5/
6
to a improper fraction: 2 5/6 = 2 5/
6
= 2 · 6 + 5/
6
= 12 + 5/
6
= 17/
6
To find new numerator:
a) Multiply the whole number 2 by the denominator 6. Whole number 2 equally 2 * 6/
6
= 12/
6
b) Add the answer from previous step 12 to the numerator 5. New numerator is 12 + 5 = 17
c) Write a previous answer (new numerator 17) over the denominator 6.
Two and five sixths is seventeen sixths
Unary minus: -17/
6
= -17/

Conversion a mixed number 5 1/
4
to a improper fraction: 5 1/4 = 5 1/
4
= 5 · 4 + 1/
4
= 20 + 1/
4
= 21/
4
To find new numerator:
a) Multiply the whole number 5 by the denominator 4. Whole number 5 equally 5 * 4/
4
= 20/
4
b) Add the answer from previous step 20 to the numerator 1. New numerator is 20 + 1 = 21
c) Write a previous answer (new numerator 21) over the denominator 4.
Five and one quarter is twenty-one quarters
Divide: -7/
8
: 21/
4
= -7/
8
· 4/
21
= -7 · 4/
8 · 21
= -28/
168
= 28 · (-1)/
28 · 6
= -1/
6
Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 21/
4
is 4/
21
) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the next intermediate step, the fraction result cannot be further simplified by canceling.
In words - minus seven eighths divided by twenty-one quarters = minus one sixth.
Add: the result of step No. 2 + the result of step No. 4 = -17/
6
+ (-1/
6
) = -17 + (-1)/
6
= -18/
6
= 6 · -3/
6 · 1
= -3
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(6, 6) = 6. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 6 × 6 = 36.
In words - minus seventeen sixths plus minus one sixth = minus three.

A farmer wishes to construct a fence around his rectangular field. The farmer has 150 feet of fence and
wishes to have the length be three more than the width. What is the width of the field. Make sure and
include feet in your answer.
Help
Answer:
The width is 36 feet
Step-by-step explanation:
If the width of the fence is x then its length is x+3.
The perimeter is 150 feet, so we have the equation:
2(x + x + 3) = 150
4x + 6 = 150
x = 144/4 = 36 feet
Luisa and Rachelle are competing for employee of the month. It is the last week, and the employee who processes the most client accounts will win. Luisa processed 15 accounts Monday, 22 accounts Tuesday, and 17 accounts Wednesday. Rachelle processed 24 accounts Monday, 18 accounts Tuesday, and 11 accounts Wednesday. Who has processed the most accounts this week, and by how many
Answer:
Luisa processed the most accounts this week, by 1.
Step-by-step explanation:
Luisa:
15 on Monday, 22 on Tuesday and 17 on Wednesday.
So a total of 15 + 22 + 17 = 54.
Rachelle:
24 on Monday, 18 on Tuesday, 11 on Wednesday.
So a total of 24 + 18 + 11 = 53.
Who has processed the most accounts this week, and by how many?
54 - 53 = 1, so Luisa processed the most accounts this week, by 1.

Answer:
(x - 2)/3
(x - 4)/-5 or (-x + 4)/5
Step-by-step explanation:
this is an inverse function, and to solve an inverse function you would :
swap x and g(x) without bringing the x coefficient with it, just simply swap the variables. Then, solve for g(x), and that's it
the first question's answer is :
g(x) = 3x + 2
x = 3(g(x)) + 2
x - 2 = 3(g(x))
(x - 2)/3 = g(x)
the second one is:
g(x) = 4 - 5x
x = 4 - 5(g(x))
x - 4 = -5(g(x))
(x-4)/-5 = g(x)
g(x) = 3x + 2
y = 3x + 2
x = 3y + 2
3y = x - 2
y = x/3 - 2/3
inverse g(x) = (x - 2) / 3
g(x) = 4 - 5x
y = 4 - 5x
x = 4 - 5y
5y = 4 - x
y = 4/5 - x/5
inverse g(x) = (4 - x) / 5

Step-by-step explanation:
( 52+2) - 3x - 6
54 - 3x - 6 So first we deal with the numbers in brackets and that is 52 + 2 giving us 54.
54 - 6 - 3x Then you simplify the expression that is collecting like terms so then we subtract 6 from 54

9x = 79
divide by 9
9x/9 = 79/9
x = 8 7/9
Answer:
Step-by-step explanation:
1+9x = 80
9x = 80-1

Answer:
Let the chord- part of VC inside smaller circle be a, and same of CU be b.
According to intersecting secants theorem we have:
CI * (CI + a) = CJ * (CJ + b)and
VC *(CI + a) = CU * (CJ + b)From the second equation we get:
CU = VC * (CI + a) / (CJ + b)From the first equation we get:
CI + a = CJ * (CJ + b) / CI,substitute this into the second equation:
CU = VC * CJ * (CJ + b) / CI * 1/ (CJ + b)CU = VC * CJ / CICU * CI = VC * CJProved
