Answer:

The difference in the cost of filling your tank between the two grades of gasoline is $2.28.

Step-by-step explanation:

Given : Our car has a 15-gallon gas tank. A lower grade of gasoline costs $2.96 per gallon. The premium grade gasoline costs $3.15 per gallon. There are three gallons left in your gas tank.

To find : What is the difference in the cost of filling your tank between the two grades of gasoline?

Solution :

The gas tank is of 15 gallons

There are three gallons left in the gas tank.

The tank has to be filled with 15 - 3 = 12 gallons

A lower grade of gasoline costs $2.96 per gallon.

So, the cost of filling the tank with the lower grade gasoline is

C_1=12\times 2.96

C_1=\$35.52

A upper grade of gasoline costs $3.15 per gallon.

So, the cost of filling the tank with the lower grade gasoline is

C_2=12\times 3.15

C_2=\$37.8

The difference in the cost of filling your tank between the two grades is

C= $37.80 - $35.52

C= $2.28

Therefore, the difference in the cost of filling your tank between the two grades of gasoline is $2.28.

Answer:

P(Green\ and\ Green) = \frac{25}{144}

Step-by-step explanation:

Given

Green=5

Blue = 7

Required

P(Green\ and\ Green)

This is calculated as:

P(Green\ and\ Green) = P(Green) * P(Green)

Since, it is a probability with replacement, we have:

P(Green\ and\ Green) = \frac{Green}{Total} * \frac{Green}{Total}

So, we have:

P(Green\ and\ Green) = \frac{5}{12} * \frac{5}{12}

P(Green\ and\ Green) = \frac{25}{144}

If the fraction 414/x-10 is equivalent to -23 ​, find the value of x. Show your work. Use reasoning to find x.
NemiM [27]

Answer:

x = -8

Step-by-step explanation:

Solve for x by getting rid of the fraction.

414/(x-10) = -23

414 = -23(x-10)

414 = -23x + 230

184 = -23x

-8 = x
