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:
You could multiply 21*21=441 if its a square

Answer:
See below:
Step-by-step explanation:
So first, Paul has a number that he got before he multiplied it, we can call that 
, and for his answer after doubling it. we'll call it 
.
So with this information, we know that 
so we can use that to make an equation.
We can solve it by first dividing on both sides and getting our answer.
Cheers! We get our final answer of 6.55.
