If 450 is 1/4 of the amount that Henry has, you can find Henry’s amount by multiplying 450 • 4 which gives you an answer of 1800
Or, if you’re looking for a more complicated way, which I doubt, you can set up the problem as:
1/4x=450 and solve by dividing 450 by 1/4
First of all, in Mathematics, OF usually represents multiplication. And % means over 100. Anyway, the question basically means 75/100 multiplied by the lifespan. According to the question, the lifespan is 18 years. So that will be;
75/100 x 18
1350/100
13.5
So your answer is 13.5 years. Hope i helped. Have a nice day.

Answer:
196π cm^3 ≈ 615.8 cm^3
Step-by-step explanation:
Put the numbers in the volume formula and do the arithmetic.
V = 1/3πr^2·h
V = 1/3π(7 cm)^2(12 cm) = 196π cm^3 ≈ 615.8 cm^3
X - the unknown number
4*x <108
x<108:4
x <22
it depends if x € N, Z or R
for R: x €(-infinite, 22)
for Z: x € {....-4,-3,-2,-1,0,1,...,21}
for N:x €{0,1,2,3,...,20,21}
