The most common size of a sedan tank is 18.5 gallons. So if it is 75% full, it contains 13.875 gallons of gas. If it recorded a mileage of 15,121 miles, mileage per gallon, therefore, is 1090 rounded off to the nearest whole number.

Given: Gas full tank of a sedan – 18.5 gallons

<span>            75% full = 13.875 gallons</span>

<span>            Mileage using 13.875 gallons of fuel = 15,121 miles</span>

The mileage per gallon computation using the ratio equation:

Ratio is 15121:13.875 or

<span>            X/1= 15121/13.875</span>

<span>            13.875x = 15121</span>

<span>            X = 15121/13.875</span>

<span>            X =1089.80 or 1090 miles per gallon (rounded off)</span>

Jonah is going to the store to buy candles for his igloo. Small candles cost $3.50 and large candles cost $5.00. He needs to buy
Semmy [17]

Answer:

x+y\geq 20

3.50x+5.00y\leq 80

Step-by-step explanation:

Let x represent number of small candles and y represent number of large candles.

We have been given that Jonah needs to buy at least 20 candles. This means number of small and large candles should be greater than or equal to 20. We can represent this information in an inequality as:

x+y\geq 20...(1)

We are also told that small candles cost $3.50, so cost of x small candles would be 3.50x.

Since large candles cost $5.00, so cost of y large candles would be 5.00y.

We are told that Jonah cannot spend more than $80, this means cost of x small candles and y large candles should be less than or equal to $80. We can represent this information in an inequality as:

3.50x+5.00y\geq 80

Therefore, our required system of inequalities would be:

x+y\geq 20

3.50x+5.00y\leq 80

The length of a rectangle is 8 inches longer than half of its width.The area of the rectangle is 18 square inches.How many inche
SOVA2 [1]

Answer:

The correct answer is 2 inches.

Step-by-step explanation:

Let l inches and w inches be the length and width of a rectangle respectively.

According to the given problem, l - 8 = \frac{w}{2}.

Area of the rectangle is given to be, according to the question, 18 square inches.

Thus l × w = 18

⇒ l × (2l - 16) = 18

⇒ 2 l^{2} - 16l - 18 = 0

⇒  l^{2} - 8l - 9 = 0

⇒ ( l - 9) ( l + 1) = 0

The possible values of l are 9 and -1. As the length cannot be equal to -1, thus the value of the length is 9 inches.

Width of the rectangle is 2 inches.
