D is the answer.
LA of cube is 4(2r.2r) = 16 r^2
LA of cylinder is 2πr x 2r = 4πr^2
16 r^2 - 4πr^2 = 4r^2(4-π)
4x-1=-2(x+1)
Distribute
4x-1=-2x-2
Move variable to left and change signs
4x+2x=-2+1
Combine like terms
6x=-1
Divide both sides by 6
X=-1/6
90 sides give us 90 angles
sum of all inside angels is (n-2) * 180 deg. where n is number of angels
so one inside angle is
(90-2)*180 deg / 90 = 88* 2 deg = 176 deg.
measure of exterior angle is 360 - 176 = 184 deg.
Answer:
1:17
Step-by-step explanation:
Find out how long it it between 5.30pm and 9am. This is 8 hours 30 minutes or 510 minutes.
Now, arrange them in the ratio of Lunch Break to Total office time
30:510. This can be simplified to 1:17
Please check if the question is worded correctly, just in case. Because ratio questions are usually based on a part and the remaining parts of the same thing, and not part to whole.
Anyway. The answer given if for the question you have typed.
Hope this helps.
