Answer:
8 in
Step-by-step explanation:
Area = (diagonal 1 x diagonal 2)/2
60 = (diagonal 1 x 15)/2
60 x 2 = diagonal 1 x 15
120 = diagonal 1 x 15
diaognal 1 = 120/15 = 8
350 mm shared in this ratio
Answer:
12 seconds
Step-by-step explanation:
Given

Determine the time taken to reach the ground
For the paper to reach the ground, y = 0
So, we have:


Collect Like Terms


Divide through by 2.5



<em>Hence:</em>
<em>Time taken is 12 seconds</em>
Volume of a cylinder is given by πr^2h
Volume of the cylindrical water cooler is π x (12/2)^2 x 15 = 3.14 x 36 x 15 = 1,695.6 in^3
Volume of water in the cylindrical cooler is 1,695.6 / 2 = 847.8 in^2
Number of drinking cups that can be filled from the cooler is 847.8/20.14 = 42 cups.
