A. because it equal to or smaller than 8.
Answer:
45
Step-by-step explanation:
20:15 the ratio can be turned to a fraction
20/15
simplify
4/3
so now add the numerator and the denominator and get 7
then do 105/7=15
and then you do
4x15=60 (Destroyers)
3x15=45 (Battleships)
45 is your answer
<u><em>Answer:</em></u>
volume of sphere = 288π ft³
<u><em>Explanation:</em></u>
volume of sphere =
where pi is a constant and r is the radius of the sphere
<u>We are given that: </u>
The diameter of the sphere is 12 ft.
<u>This means that</u> the radius = ![\frac{12}{2} = 6 ft](https://tex.z-dn.net/?f=%20%5Cfrac%7B12%7D%7B2%7D%20%3D%206%20ft%20)
<u>Substitute with the radius in the above equation to get the volume as follows:</u>
volume =
ft³

I think I know how to do it
Your equation is:
P₁V₁ = P₂V₂
You Know:
Initial:
P₁ = 84 Pa
V₁ = 336 L
New:
P₂ = ?
V₂ = 216L
Plug this into the equation:
P₁V₁ = P₂V₂
(84 Pa)(336 L) = P₂(216 L) Divide 216 on both sides
![\frac{(84Pa)(336L)}{216L}=\frac{(P_{2})(216L)}{216L}](https://tex.z-dn.net/?f=%5Cfrac%7B%2884Pa%29%28336L%29%7D%7B216L%7D%3D%5Cfrac%7B%28P_%7B2%7D%29%28216L%29%7D%7B216L%7D)
130.6666666 = P₂
(if your doing significant figures, you have 2 sig figs)
130 Pa = P₂
