Answer:
Step-by-step explanation: The formula to find the surface area of a rectangular prism is A = 2wl + 2lh + 2hw, where w is the width, the l is the length, and the h is the height.
Answer:
This function represents a direct variation because it passes through the origin and has a constant rate of change of $5 per hour.
Step-by-step explanation:
Given
Time ------ 0 ----- 2 ------- 4 ----- 6 -----8.
Cost ------- 0 ----- 10 ----- 20 ----30 ----40
Required
Explain why or why not it is a direct variation?
First, we calculate the slope of the table.

Where:


So:




Next, we determine the equation using




<em>The above shows a direct variation with 5 as its constant of proportionality of variation.</em>
You have to get change 1/2 into a fraction with a common denominator. 1/2 turns into 4/8. Now you have to do 4/8 - 1/8 which is now 3/8
