Answer: NO
Step-by-step explanation: No, he is not correct. Because if you are expected to do 10 hrs that's 100% and if you go over by 1 hour, that hour would be equivalent to 10% because 100 divided by 10=10. So when Marcus says he spent 110% MORE time doing his homework, that is incorrect because 110%=11 EXTRA hours doing his work. The correct answer would be 10% extra since he only went over 1 hour.
Answer:
64 m³
Step-by-step explanation:
For similar figures
linear ratio = a : b , then
area ratio = a² : b² and
volume ratio = a³ : b³
Given
area ratio = 64 : 144 , then
linear ratio = : = 8 : 12 = 2 : 3
Then
volume ratio = 2³ : 3³ = 8 : 27
let volume of smaller cylinder be x, then
= ( cross- multiply )
27x = 8 × 216 = 1728 ( divide both sides by 27 )
x = 64
Volume of the smaller cylinder = 64 m³
Answer:
Let the number be x. Here x acts as any no u think of..right??
step 1: 2x
step 2: 2x+6
step 3: (2x+6)/2
step 4: (2x+6)/2 - x = (x+3) - x = 3 (cancelling 2 in (2x+6)/2,we get x+3 ..dnt get confused :D )
That's y d ans s always 3. :) :)
