Answer:
63 ft^2
Step-by-step explanation:
We know that the area for the rectangle is 72 feet squared.
We also know that the area for the triangle is 9 feet squared.
To find out the area of the whole thing you subtract 72-9 whcih gives you 63.
A=3,500×(1+0.011÷12)^(12×4)
A=3,657.36
Interest earned
=3657.36-3500=157.36
Capacity of the pool = 30 x 20 x 5 = 3000 ft³
Amount of water already filled = 30 x 20 x 4 = 2400 ft²
Amount of water needed to full the pool = 3000 - 2400 = 600 ft²
---------------------------------------------------------------------------------------
Answer: 600 ft² of water is needed to fill up the pool.

Answer:
<h3> C. y + 7 = -7(x - 3)</h3>
Step-by-step explanation:
The equation of a line is:
y - y₀ = m(x - x₀)
where <em>m</em> is the slope and <em>(x₀, y₀)</em> is the point which the line passes through
The product of slopes of two perpendicular lines is -1
so if given lines slope is ¹/₇ them:
¹/₇·m = -1
m = -7
(3, -7) ⇒ x₀ = 3, y₀ = -7
Therefore:
y - (-7) = -7(x - 3)
<u> </u><u>y + 7 = -7(x - 3) </u>
Answer:
x = -22
Step-by-step explanation:
6(x+15) = -42
x+15 = -7
x = -22
