They intersect at one point, perpendicular lines form right angles (90 degree angles)

7/20 in decimal form

zhannawk [14.2K]

Well, we would have to divide 7 into 20 in order to find the decimal, so 7 divided by 20 = 0.35, so 7/20 as a decimal is 0.35, and if you move the decimal two places to the left, it is also 35%.
I hope I helped! =D

The fencing William chooses costs $29.53 per foot, including installation. What will the fencing cost? Show your work.

TiliK225 [7]

Answer:

$C = 29.53x$

Step-by-step explanation:

Given

$Unit\ cost = \$29.53$

Required

The cost of fencing (C)

The cost is calculated as:

$C = Unit\ Cost * Perimeter\ of fencing$

Let:

$x \to Perimeter\ of fencing$

So, we have:

$C = Unit\ Cost * x$

$C = 29.53 * x$

$C = 29.53x$

The question cannot be solved further since the dimension of the fence is not given

If you know the dimension, calculate the fence perimeter and substitute the value for x
