Answer: 7.5
Form your proportion. Let x be the width of QRST.
Length of ABCD Length of QRST
----------------------- = -------------------------
Width of ABCD Width of QRST
8/5 = 12/x
Solve for x by cross-multiplying.
(8)(x) = (12)(5)
8x = 60
x = 7.5
Answer:
Blue

I used a graphing calculator called Desmos.
Answer:
b
Step-by-step explanation:
because we can not some times change the places in addition so b is the correct answer
It’s 21.99
Use c=2pi*radius
Diameter divided by 2 = radius
Answer:
The diver will hit the water at 1.5 seconds
Step-by-step explanation:
Given

Required (Missing from the question)
When will the diver hit the water?
To do this, we simply solve for t
When the diver hits the water, the height is 0 (at that point)
So, substitute 0 for h in 

Divide both sides by -16




Split
or 
Solve for t
or 
But time (t) can not be negative.
So:

Hence, the diver will hit the water at 1.5 seconds
