Kevin has a rectangular
Nikitich [7]

Answer:

20 feet long

Step-by-step explanation:

To solve this you need to use the Pythagorean theorum, a^2+b^2=c^2, where c is the length of rope needed and A and B are the side lengths. Think of it like a right triangle.

So, the equation is

12^2+16^2=c^2

Which is then

144+256=c^2

c^2=400

And the possible values of c are 20 and -20.

From here we know the answer cannot be -20 because you cannot have a negatively long length of rope, so the answer must be 20 feet.

devlian [24]

Answer:

  1. 32
  2. 400

Step-by-step explanation:

Lets start by defining the numbers in the equation.

This  equation is in slope-intercept form meaning that it is y=mx+b or y = b+mx they are both the same

In slope-intercept form,

  • m = slope or rate
  • and b = y-intercept

Th equation is y=400+32x so now we know

  • b=400
  • and m=32

For the first question the change per minute is the rate so it is <u>32.</u>

For the second question the starting amount is the same as the y-intercept so it is <u>400.</u>
