Answer:
1. True, 2. False, 3. I am blind.
Step-by-step explanation:
For the 3rd one I cannot confirm becaue I am blind.
Surface area of a ball:
S=4πr^2=4*π*5^2=100π
Volume of a circle:
V=4/3*π*r^3=4/3*π*125=(500/3)*π=165π
The approximate surface-area-to-volume ratio would be 1:1,5
Answer:
x=y
Step-by-step explanation:
let x be the number of tennis balls and y the number of rackets.
-We divide the number of balls by the number of rackets to find out their ratio of proportionality:

-Hence, for each one ball there is one racket, so;

-This relationship is linear in nature, a direct variation, and can be graphed as attached below:
Answer:
Step-by-step explanation:
Solution given:
y=70x+
Comparing above equation with y=mx+c
we get
m=70
So
<u>Slope</u><u>=</u><u>7</u><u>0</u>
