Answer:
0.3 or 3/10
Step-by-step explanation:
If 
= 6, then p must be 0.5 (since 3/[1/2] is also 3x2).
If 
= 15, then q must be 0.2 (since 3/[1/5] is also 3x5).
p - q would be 0.5 - 0.2, which means the final answer is 0.3 (3/10).
Answer:
<u>2,592,100 m³</u>
Step-by-step explanation:
<u>Volume of Square Pyramid</u>
- V = 1/3a²h
- V = 1/3(230)²(147)
- V = 49 x 52900
- V = <u>2,592,100 m³</u>
Answer:
4 mph
Step-by-step explanation:
The speed downstream is (28 mi)/(2 h) = 14 mph.
The speed upstream is (18 mi)/(3 h) = 6 mph.
The speed of the current is half the difference of these:
(14 mph -6 mph)/2 = 4 mph
_____
The current adds to the downstream speed and subtracts from the upstream speed, so the difference of those speeds is twice the current's speed.
