Answer:
Water level in the reservoir is falling at the rate of 0.398 ft per minute.
Step-by-step explanation:
From the figure attached,
Water level in the reservoir has been given as 10 feet and radius of the reservoir is 4 feet.
Let the level of water in the reservoir after time t is h where radius of the water level becomes r.
ΔABE and ΔCDE are similar.
Therefore, their corresponding sides will be in the same ratio.
--------(1)
Now volume of the water V =
From equation (1),
V =
V =
Since feet³ per minute and h = 5 feet
feet per minute
Therefore, water level in the reservoir is falling at the rate of 0.398 feet per minute.
Answer:
y=40.5
Step-by-step explanation:
you need to get y out of a fraction, to do so multiply by the denominator on both sides
3(2/3y) = 3(27)
then divide to solve for y
2y = 81
y=40.5
Divide 3 on both sides
x=3.33
Answer:
This is called a <u><em>parallelogram</em></u>
<u><em>Now, Area:</em></u>
Area = base * Height
Area = 4 * 3
Area = 12 cm²
