25% as a fraction is 1/4 or 25/100 so as a decimal its 1/4 of 1 which is .25
Answer:
x2 + 7x + x2 + 7x + 9 = 3
I can't answer this question if we don't know by what scale the cylinder's radius was reduced. Luckily, I found the same problem that says the radius was reduced to 2/5. So, we find the ratio of both volumes.
V₁ = πr₁²h₁
V₂ = πr₂²h₂
where r₂ = 2/5*r₁ and h₂ = 4h₁
V₂/V₁ = π(2/5*r₁ )²(4h₁)/πr₁²h₁= 8/5 or 1.6
<em>Thus, the volume has increased more by 60%.</em>
ANSWER:
24 minutes
40% of 1 hour is equivalent to 24 minutes.
STEP-BY-STEP EXPLANATION:
1 hour = 60 minutes
If:
100% = 60 minutes
Then:
100% ÷ 2.5 = 60 minutes ÷ 2.5
40% = 24 minutes
THEREFORE:
40% of 1 hour is equivalent to 24 minutes.
