Answer:
A) R = 1900 -24t
B) 1684 billion barrels
C) 79.17 years
Step-by-step explanation:
<h3>A)</h3>
Reserves start at 1900 billion barrels and decrease by 24 billion barrels each year. The value for t=0 is 1900; the value for t=1 is 24 less.
R = 1900 -24t
__
<h3>B)</h3>
For t=9, the reserves will be ...
R = 1900 -24(9) = 1900 -216 = 1684 . . . . billion barrels
__
<h3>C)</h3>
The reserve will be 0 when ...
0 = 1900 -24t
24t = 1900 . . . . . add 24t
t ≈ 79.17 . . . . divide by 24
Reserves will be gone in about 79.17 years.
Answer:
Step-by-step explanation:
Let the capacity of the bin is x gallons.
1/2 gallon is 2/3 of x
<u>Convert this into equation and solve for x:</u>
- 1/2 = 2/3x
- x = 1/2 : 2/3
- x = 1/2 * 3/2
- x = 3/4
3/4 gallons of water will fill the bin
