Answer:
125/216 or (5/6)³
Step-by-step explanation:
height of water column=5/6 ×12=10 cm
radius of water level=10/12×6=5 cm
volume of water=π ×5²×10=250 π cm³
volume of cone=π×6²×12=432 π cm³
reqd. ratio=250 π/432 π=125/216=(5/6)³
I hope that the attachment helps you..
Step-by-step explanation:
Here we will, Provide index power 5 on both the sides, so that we can cancel out the 5th power root in the L.H.S
so we get as,
==> x+7 = (-2)^5
==> x+7 = -32
==> x = -32-7
==> x = -39
hence, x = -39
Option A.) is correct.
Answer:
81 cubic feet of wood
Step-by-step explanation:
Divide it into 5 sections, each 3 feet long because it is 15 feet long.
(1*3*3) + (2*3*3) + (3*3*3) + (2*3*3) + (1*3*3) =
9 + 18 + 27 + 18 + 9 = 81
The usefulness is that this data allows you to understand how well students perform with their instruction, based on a standardized test. The limitation is that the scores don't account for different situations that may affect the results you receive.
