Answer:
4/35
Step-by-step explanation:
Probability of 1 student having no hw is 4/7, then 3/6, then 2/5
4/7 x 3/6 x 2/5 reduces to 4/35
We know the combined area is 100π, and the combined area includes the white section as well as the orange section.
now, if we take the area of the white circle, and "subtract" it from the combined area, we're in effect, making a whole in the larger circle, and what's leftover is just the orange part, because the white would have been subtracted out,
Given:
Perimeter of rectangular swimming pool = 84 meters
Width of pool = 3/4 of the length
Let's find the length and width of the pool.
Since the swinning pool has the shape of a rectangle and we have the perimeter, to find the length and width, apply the perimeter of a rectangle formula:

Where:
L is the length
W is the width.
Given:
W = ¾L
Substitute 84 for perimeter and ¾L for W.
Hence, we have:

Let's evealuate the equation and solve for L.
We have:

Divide both sides by 3.5:

To solve for the width W, substitute 24 for L in (W=¾L)

Therefore, the length of the swimming pool is 24 meters, while the width is 18 meters.
ANSWER:
Length = 24 meters
Width = 18 meters
The area of a trapezoid is A = (a+b/2)(h).
So just plug in your numbers.
