f(x) = -720h + 10080
10080 is the total amount of water in the pool, 720 is the amount of water you lose each hour.
"h" is the number of hours the pool has been draining, and since you know the pool has been draining for 12 hours, you can plug in 12 for "h".
f(x) = -720h + 10080
f(x) = -720(12) + 10080
f(x) = -8640 + 10080
f(x) = 1440
After 12 hours of draining, 1440 is the amount of water left in the pool. (I don't know the units [ex: gallons, etc.])
D. they are corresponding angles and their measures add to 180°
Answer:
x = 23
Step-by-step explanation:
Add 20 to both sides of the equation
x-20=3
−20+20=3+20
Simplify
Solution:
x= 23
From my research, the available data in the problem is as follows:
<span>No. of Heads | Probability
0 1/16
1 4/16
2 6/16
3 4/16
4 1/16
To calculate the average amount spent by a student in an hour:
[(0 * 1/16) + (1 * 4/16) + (2 * 6/16) + (3 * 4/16) + (4 * 1/16)] * 2
= 4
Therefore, the library earns $4 per student each hour</span>
Answer:
5/4 ft
Step-by-step explanation:
Given data
Area= 5/12 square feet
Height= 1/2 ft
Base=????
We know that the area of a triangle is given as
Area= (1/2)B*H
substitute
5/12= 1/2* B* 1/2
5/12= B/4
cross multiply
12B= 20
B= 20/12
B= 5/3
Hence the base is 5/4 ft
