Answer:
B. (x - 3²)(y-6)
Step-by-step explanation:
Find the expression with a value of 30;
when x = -1 and y = 3:
A. (x - 3²).y-6
(-1 - 9).3-6 = -10 x 3 -6 = -30 - 6 = -36
B. (x - 3²)(y-6)
( -1 -3²)(3 - 6) = (-1 -9)(-3) = 30
C. x - 3² . (y-6) = -1 - 9.(3-6)
= -1-9.-3
= -1 - 9 x -3
= -1 + 27
= 26
D. x - 3².y-6 = -1 - 9. 3 - 6
= -1 - 27 - 6
= -34

A rectangular prism is 2 inches by 4 inches by 6 inches.
Kimaya says, “It takes more 2/5-inch cubes to fill the prism than 1/5-inch cubes.”
Do you agree with Kimaya? Explain or show your reasoning.
Answers
No, I do not agree with Kimaya. The volume of the rectangular prism is 2 inches x 4 inches x 6 inches = 48 cubic inches. To fill the rectangular prism with 2/5-inch cubes, you would need 48 cubic inches / (2/5) cubic inches per cube = 120 cubes. To fill the rectangular prism with 1/5-inch cubes, you would need 48 cubic inches / (1/5) cubic inches per cube = 240 cubes.
So, it takes less 2/5-inch cubes to fill the prism than 1/5-inch cubes.
Another way to think of it is that the larger the cubes, the less number of cubes you need to fill the same volume, as the cubes are larger in size.
Simple Explanation: 2/5 in. cubes are more than 1/5 in. cubes, so 1/5 in. cubes would take 2x more to fill than 2/5 in.
Complex Explanation: 2 in. x 4 in. x 6 in. is 48 cubic in. and to fill 48 cubic in. using 2/5 in. per cube, it would be 120. as for 1/5 in., to fill 48 cubic in. with that would be 240. Easier way to think of it is that 2/5 in. cubes are already 120 and 1/5 would be doubling that so all you gotta do is multipy 120 x 2 since filling it with 1/5 would be 2x the amount than 2/5.

The answer is 8 so its a direct proportion
I think...
The constant of Proportionality is 8.
What is constant of Proportionality?If the ratio of one variable to the other is constant, then there is a proportional relationship between the two variables. If x and y are in a proportional relationship, then the ratio of y to x is the constant of proportionality. We can also express it as x is to y at times.
Given:
Total Baseball Caps= 30
Total amount of Cap= $240
let the number of caps sold be c.
Then, the equation is
30 c= 240
and, c= 240/30
c= 8
Hence, the constant of Proportionality is 8.

The price of the box of 10 markers is $7. The price of the box of 24 markers is $14. All prices without tax, and the price of the boxes is the same.
Write an equation which tell the price Y for the number of markers X.
Answers
Answer:
Step-by-step explanation:
let x represent the number of markers.
Let y represent the cost for x boxes of markers.
If we plot y on the vertical axis and x on the horizontal axis, a straight line would be formed. The slope of the straight line would be
Slope, m = (14 - 7)/(24 - 10)
m = 7/14 = 0.5
The equation of the straight line can be represented in the slope-intercept form, y = mx + c
Where
c = intercept
m = slope
To determine the intercept, we would substitute x = 24, y = 14 and m = 0.5 into y = mx + c. It becomes
14 = 0.5 × 24 + c = 12 + c
c = 14 - 12
c = 2
The equation would be
y = 0.5x + 2
if all functions are relations, are all relations functions? Explain your answer
Answers
Answer:
No, because some relations are not functions. Relations are equations that begin with x=, and let's say x=5.
This is not a function because if you graph this line, it is vertical, and functions can't share the same x coordinate point (input) with other y coordinate points (output). There must be one output for every input, meaning that this relation is not a function.

Answer:
320cm³
Step-by-step explanation:
to find the area of the rectangular prism we can use the formula V= LWH
6×8×5=240 cm³
to find the area of the triangular prism we use the formula V=1/2LWH
4×8×5×1/2=80cm³
240+80=320
Answer:
320cm³
Step-by-step explanation:
First, find the area of the triangle.
a=hb/2 (area = height * base / 2)
area = 4*8/2=16
Then, find the area of the rectangle.
a=wl (area = width * length)
area = 6*8=48
Then, you add the two totals and multiply the width (5cm).
16+48=64
64*5=320

First, find the unit rate of both companies.
To find company A's unit rate find what is the numerator and denominator. This is 65/13. We want a unit rate where 1 is in the denominator, so we divide the top and bottom by 13:
65 cents / 13
--------------------
13 dollars / 13
Divide both by 13 and you get 5 cents per dollar.
Now find company B's unit rate. Find the numerator and denominator, 11/40.50. Now this time we want 1 where the denominator is again. So we divide the top and bottom by 40.5.
11 cents ÷ 40.5
----------------------------------
40.5 dollars ÷ 40.5
Divide by 40.5 and you get 0.271605 cents per dollar. Round to the hundreths and get 0.27 cents per dollar
Now time to find how much company A charges more than company B. subtract 0.27 by 0.05 and you have your answer! x = 0.22 cents
