Answer:
22 miles per hour
Step-by-step explanation:
Against the current, the boat's rate of travel is ...
(120 mi)/(6 h) = 20 mi/h
With the current, the boat's rate of travel is ...
(120 mi)/(5 h) = 24 mi/h
___
The sum of boat speed (b) and current speed (c) is 24 mph. The difference is 20 mph. This lets us write the equations ...
b + c = 24
b - c = 20
Adding these two equations together, we get ...
2b + 0c = 44
b = 22 . . . . . . . . divide by 2
The rate of the boat in still water is 22 miles per hour.
Answer:
c. 4187 cubic units
Step-by-step explanation:
V = 4/3 π r³
= 4/3(3.14)(10)³
= 4186.6666666
45 45 90 right triangle BCA
ratio of leg : leg : hypo = y : y: y√2
in this case hypo = 3√2 so leg = y = 3
answer
y = 3

Answer:
A. 2.82 m
Step-by-step explanation:
<u>The missing side we are trying to find is the hypotenuse, this is because it is the longest side of a right triangle.</u>
<em><u>The Pythagorean Theorem is used:</u></em>
<em><u /></em>
<em><u>Plug in the given numbers (2), accordingly:</u></em>
<em><u /></em>
<em><u>Take the square root of both sides:</u></em>
<em><u /></em>
2.82 ≈ c
