354 as a percentage is 354%
35.4 as a percentage is 35.4%
It sounds like <em>R</em> is the region (in polar coordinates)
<em>R</em> = {(<em>r</em>, <em>θ</em>) : 2 ≤ <em>r</em> ≤ 3 and 0 ≤ <em>θ</em> ≤ <em>π</em>/2}
Then the integral is
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)
Setup the equation from the words as follows:
√
3x/5
=x
Simplify this to:
0=x(5x−3)
Since we are toldx≠0,x=3/5.
