Answer:
The rate of change of water in the pool is 400 gallons / hour
Step-by-step explanation:
We are given
At 6:00 AM:
there were 400 gallons of water in the pool
so,
At 11:00 AM:
there were 2400 gallons of water in the pool
so,
now, we can find time between
t=11-6=5 hours
now, we can use formula
rate of change of water in pool is
=( change in water quantity)/( total time)
so, we get
now, we can plug values
So,
The rate of change of water in the pool is 400 gallons / hour
Answer:
∠GHE = 55°
Step-by-step explanation:
ABCD is a quadrilateral (4 sided figure). We know that the sum of the interior angles (4 angles) of a quadrilateral in 360°.
Thus, A + B + C + D = 360
<em>we know b = c = 90 and a = 125, thus we can find D.</em>
<em>125 + 90 + 90 + D = 360</em>
305 + D = 360
D = 360 - 305 = 55°
<u>Note:</u> since Quadrilateral ABCD is congruent to Quadrilateral EFGH, then the measure of D is equal to measure of H (Angle GHE). Thus
∠GHE = 55°
2nd answer choice is correct
I think it’s 7.14 or atleast that’s what I got
