Answer:
769.6902 (or 769.3) cubic feet of water
Step-by-step explanation:
πr^2
r = 7
5 x π(7)^2 = 769.6902 (or 769.3 using 3.14)
There are 12 months in a year and each year it decreases 6% so therefore each month it decreases .5%.
If you were asking the the amount it depreciates each month then you take .5% or .005 of 12000 which is 60 dollars a month.
What do you mean this sentence?
the time a pump takes to drain the pool varies inversely with the power in watts of the pump,
The meaning would be : if we have a power in watts greater the time to drag the pool will be less because the relation between power and time is inverse.
40 watts--------------5 hours)
100 watts------------ x
because the relation between power and time is inverse, we multiply directly.
40 watts(5 hours)=100 watts x
x=(200 watts hours) / 100 watts=2 hours.
Answer: the time would be 2 hours. (the new pump is faster)
Answer:
16/1 I think
Step-by-step explanation:
This is a 45-45-90 triangle or a right triangle created by the sides.
Because of this being a right triangle and 45 degrees being given already for one angle you would add 90 and 45 which will give you 135. You would subtract 135 from 180 because all the angles of a triangle add up to 180°. 180-135=45. X=45°
