Answer:
<em>$ 33.6 to fill this tank, provided a community cost of $2.8 per gallon</em>
Step-by-step explanation:
1. Let us first find the volume of the gas the tank, by the general multiplication of Base * height ⇒ 11 inches * 1.25 feet * 1.75 feet. For the simplicity, we should convert feet ⇒ inches, as such: 1.25 feet = 1.25 * 12 inches = 15 inches, 1.75 feet = 1.75 * 12 inches = 21 inches. Now we have a common unit, let us find the volume ⇒ 11 in. * 15 in. * 21 in. = 3465 inches^3.
2. Let us say that the the average price of gas in my community is $2.8 per gallon. We would first have to convert inches ⇒ gallons provided 1 gallon = 231 inches: 3465/231 = 15 gallons.
4. Now simply multiply this price of 2.8 dollars per gallon by the number of gallons to receive the cost if the tank was full: 2.8 * 15 = <em>$ 42 if this tank was full provided a community cost of $ 2.8 per gallon</em>
5. Now this tank is 20% full, so we must calculate the cost to fill the other 80% up. That would be 80/100 * 42 = 4/5 * 42 = 168/5 = <em>$ 33.6 to fill this tank, provided a community cost of $2.8 per gallon</em>
The value of the algebraic expressions when x = 5 are:
a) x² = <em>25</em>
<em>b) </em>(x + 3)² = <em>64</em>
We are given that x = 5.
<em>Required:</em>
Find the value of a.) x² and b.) (x + 3)²
To find the value of each algebraic expression when x = 5, substitute the value of x.
<em>Thus:</em>
a.) x²
x² = (5)²
x² = <em>25</em>
<em />
b.) (x + 3)²
(x + 3)² = (5 + 3)²
(x + 3)² = (8)²
(x + 3)² = <em>64</em>
Therefore, the value of the algebraic expressions when x = 5 are:
a) x² = <em>25</em>
<em>b) </em>(x + 3)² = <em>64</em>

Subtract the new amount from the original amount:
64 - 85 = -21
Now divide that by the original amount:
-21 / 85 = -0.247
Multiply that by 100 for the percentage:
-0.247 x 100 = -24.7%
Rounded to the nearest percent is -25%
