Answer:
7000 cubic yards
Step-by-step explanation:
Given :The volume of water in a reservoir decreases 21,000 cubic yards over a 3-month period.
To Find:What is the average change in volume per month?
Solution:
Since we are given that The volumes of water decreases by amount in 3 months = 21000 cubic yards
So, the volume decreased per month =
=
Thus the volume decreased per month is 7000 cubic yards .
Hence the average change in volume per month is 7000 cubic yards

Answer:
15°
Step-by-step explanation:
Since P is on the median of ΔABC, it is equidistant from points B and C as well as from C and Q. Thus, points B, C, and Q all lie on a circle centered at P. (See the attached diagram.)
The base angles (B and C) of triangle ABC are (180° -30°)/2 = 75°. This means arc QC of the circle centered at P has measure 150°. The diameter of circle P that includes point Q is defined to intersect circle P at R.
Central angle RPC is the difference between arcs QR and QC, so is 180° -150° = 30°. Inscribed angle RQC has half that measure, so is 15°. Angle PQC has the same measure as angle RQC, so is 15°.
Angle PQC is 15°.
