Car Rentals rents cars and trucks for $25 and $30 a

day, respectively. Last Tuesday, they rented all but

7 rental vehicles and reported $195 in lost rent.

How many trucks were not rented last Tuesday?

Write the system of equations and solve for how

many trucks.

Answers

Answer 1

Answer:let x be the number of cars, and 7-x be the number of trucks.

25x + 30(7-x) = 195

25x + 210-30x = 195

5x = 15

x = 3

So, 3 cars were not rented. If 7 total vehicles were not rented, 7 - 3 cars = 4 Trucks

4 Trucks were not rented.

A study gathers data on the outside temperature during the winter, in degrees Fahrenheit, and the amount of natural gas a household consumes, in cubic feet per day. Call the temperature x and gas consumption y. The house is heated with gas, so x helps explain y. The least-squares regression line is yhat = 1344 – 19x. 1. On a day when the temperature is 20F, the regression line predicts that gas used will be about

Answers

Answer:

The answer is "964 cubic-feet".

Step-by-step explanation:

Given regression equation:

[tex]\to Y = 1344 - 19X\\\\\to X= 20 \ F[/tex]

Putting the value of x into the above equation:

[tex]\to Y = 1344-19\times20\\\\[/tex]

Flve tickets to a carnlval cost $45. How much would seven
tickets cost?

Answers

Answer:

$63

Step-by-step explanation:

In order to solve this problem, we need to find the unit price, which is the price per 1 ticket in this case. To find this, we need to divide $45 by 5 because each ticket is the same amount: $45 / 5 = $9. So each ticket is $9.

Now, we need to find how much 7 tickets would cost. To do this, multiply the $9 / ticket by 7 tickets: $9 * 7 = $63.

This, 7 tickets would cost $63.

Hope this helps! God Bless u!!!

Answer:

You know that the legs are equal because it's isosceles, so AB = AC. This means:

Kierston needs to paint a wall of the youth center. She knows that 1 can of paint covers an area of 2.2 square meters. Kierston measures the wall using a meter stick as shown below. How many cans of paint must kierston buy to paint the wall of the youth center?

Answers

Answer:

See Explanation

Step-by-step explanation:

Given

[tex]1\ can = 2.2m^2[/tex]

Required

Determine the number of cans for the wall

The dimension of the wall is not given. So, I will use the following assumed values:

[tex]Length=20m[/tex]

[tex]Width = 44m[/tex]

First, calculate the area of the wall

[tex]Area = Length * Width[/tex]

[tex]Area = 20m * 44m[/tex]

[tex]Area = 880m^2[/tex]

If [tex]1\ can = 2.2m^2[/tex]

Then [tex]x = 880m^2[/tex]

Cross Multiply:

[tex]x * 2.2m^2 = 1 * 880m^2[/tex]

[tex]x * 2.2m^2 = 880m^2[/tex]

[tex]x * 2.2 = 880[/tex]

Make x the subject

[tex]x = \frac{880}{2.2}[/tex]

[tex]x = 400[/tex]

400 cans using the assume dimensions.

So, all you need to to is, get the original values and follow the same steps

Find a simplified expression for the area of the shaded region below

Answers

Answer:

Area of the shaded region = (8x + 6)

Step-by-step explanation:

Area of the shaded region = Area of the large rectangle - Area of the smaller rectangle

Area of the large rectangle = Length × width

                                             = (x + 3)(x + 2)

                                             = x(x + 2) + 3(x + 2)

                                             = x² + 2x + 3x + 6

                                             = x² + 5x + 6

Area of the smaller rectangle = x(x - 3)

                                                 = (x² - 3x)

Area of the shaded region = (x² + 5x + 6) - (x² - 3x)

                                            = x² + 5x + 6 - x² + 3x

                                            = (8x + 6)

What single percentage change is equivalent to a 11% increase followed by a 13% increase?

Answers

Answer:

The equivalent percentage change is [tex]25.43[/tex] %

Step-by-step explanation:

Let there be a number 100

It is first increased 11 % , so the new number would be [tex]100 + 11[/tex]% of 100

i.e [tex]100 + 11 = 111[/tex]

Now, this number 111 is further increased by 13 % so the new number is [tex]111 + 13[/tex]% of 111

125.43

So , the total increase or equivalent increase is

[tex]\frac{125.43-100}{100} *100\\= 25.43[/tex]%
