A i hope it helps each trial must have all outcomes classified into two categories
xy = 30
x - y = 1
x + y = 11
First, we need to consider factors of 30:
1, 2, 3, 5, 6, 10, 15, 30
Which two of these, subtracted, would equal 1?
5 and 6
6 x 5 = 30
6 - 5 = 1
6 + 5 = 11
Answer:
A=(1/2)BxH
10x6=60m
<span>formula for the volume of a cylinder
V = πr2h
Divide both sides by πr2 to isolate h.
V / πr2 = πr2h / πr2
You find the height, h, is equal to .
V / πr2 = h
H = V / πr2</span>
