You install 404 feet of fencing along the perimeter of a rectangular yard.
Gemiola [76]

Answer:

The length of the yard is 102

Step-by-step explanation:

If the width of the yard is 100 feet, and it's a rectangular, that means the other side of the rectangle is also equal to 100 feet. So so far we have 200 feet of the yard covered. Then we do 404-200=204. So the combined length of both the sides is 204. Since they both equal the same length, we can then do 204/2 to get 102. So one side length is 102 and the L, W, L, W of the rectangle is 102, 100, 102, 100. In other words, the rectangle is 102 by 100.

A politician's support grew from 42% by 3 percentage points to 45%. What percent (relative) change is this? Round your answer to
gregori [183]

Answer:

7.1%

Step-by-step explanation:

The formula for percentage relative change =

[Final value - Initial value/Initial value] × 100

From the above question

Initial value = 42 %

Final value = 45%

= 45 - 42/ 42 × 100

= 3/42 × 100

= 7.1428571429 %

Therefore, approximately to the nearest tenth, the percentage relative change = 7.1%
