x * 2/5 = 3/20

2/5 = 0.4

3/20 = 0.15

0.15 / 0.4 = 0.375

0.375 = x

x = 3/8

Answer:

Not true.

Step-by-step explanation:

Whole numbers are integers that are 0 or greater than 0.  Since 0 is a whole number and x > 0 does not include 0, the statement is not true. Only the sign ≥ includes 0.

The boys kept adding sand, and ten minutes later the volume of the sand cone had increased by 30%. What is the exact volume of t
RideAnS [48]

Answer:

a) 84π b) 109.2π

Step-by-step explanation:

The formula to find this is v=πr^2h/3

r=d/2. so the radius (r) is 6 because you have to divide the diameter (12) by 2. and the height is 7. so, 6^2=36 and 36x7=252.

252/3=84

and because the question is asking for the EXACT value, you need to just put the pi symbol next to it. Final answer for a is 84π

B) you need to find 30% of 84, which is 25.2 and add it to 84, and you will get 109.2! Final answer is 109.2π.
