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.

Step-by-step explanation:
Answer: 22 square feet
Step-by-step explanation:
Using Heon's formula, the are can be found with:
Where s is half the perimeter
a, b and c are sides
Perimeter = a + b +c
24 = 9 + 10 + c
c = 24 - 9 - 10
c = 5 feet
s = 24 / 2 = 12
Area
= 22 ft²
