Answer:
39.5% (3 sf)
Step-by-step explanation:
Area of 1 window: 4×5 = 20 ft²
2 windows: 3×20 = 60ft²
Area of the wall: 8×19 = 152 ft³
Percentage of window area:
60/152 × 100 = 39.47368421%
= 39.5% (3 sf)

Step-by-step explanation:
Answer:
y=-1/2x+2
Step-by-step explanation:
First, the slope of perpendicular line have negative reciprocal coefficients. In this case the coefficient is 2, The reciprocal of 2 is 1/2 and the negative of 1/2 is -1/2. So x will have a coefficient of -1/2.
Second, find the equation with a slope of -1/2 that passes through (-2,3). There are a few ways to do this. I like to plug the given x value into the expression -1/2x, so -1/2(-2) which equals positive 1 and for the line to pass through the point (-2,3) you need to add 2. So: y=-1/2x+2
