Answer:

$25

Step-by-step explanation:

Derive an equation to represent the cost of using each ride.

Sal's Car Rides:

Using 2 pairs of values from the table, (0, 40) and (20, 80), find the slope, m (fee per mile).

[tex] m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{80 - 40}{20 - 0} = \frac{40}{20} = 2 [/tex]

The y-intercept, b, is the one-time fee for fuel. This is the value of the cost ($) when number of miles traveled is 0.

Thus, b = 40.

Substitute m = 2, and b = 40 into [tex] y = mx + b [/tex].

Equation for the total cost for Sal's Car Rides would be:

[tex] y = 2x + 40 [/tex].

Find the total cost to be charged if a customer requires the a car service for 80 miles if he chooses Sal's Car Rides.

Simply substitute x = 80 in [tex] y = 2x + 40 [/tex].

[tex] y = 2(80) + 40 = 200 [/tex]

The customer would pay $200.

Ray's Limo:

The equation that represents the total cost (y) to be charged for number of miles (x), given that $2.50 is charged per mile plus a one-time fee of $25 for fuel, would be:

[tex] y = 2.5x + 25 [/tex].

If a customer uses Ray's Limo services for 80 miles, the cost charged would be:

Substitute x = 80 in [tex] y = 2.5x + 25 [/tex].

Thus:

[tex] y = 2.5(80) + 25 = 225 [/tex].

The fee the customer would pay = $225 for using Ray's Limo services.

Therefore, if the customer takes Sal's Car Rides instead of Ray's Limo, he would save, $225 - $200 = $25.

The customer would save $25.

Answer:

12.5

Step-by-step explanation:

3 scoops = 1 cup

6 scoops = 2 cups

9 scoops = 3 cups

12 scoops = 4 cups

Answer:

The total number of sandwiches sold that day was 90.

Step-by-step explanation:

Given that the 36 cheese sandwiches sold represent 40% of the total sandwiches sold on that day, to obtain the total number of sandwiches sold the following calculation must be made:

40 = 36

100 = X

((100 x 36) / 40) = X

3600/40 = X

90 = X

Therefore, the total number of sandwiches sold that day was 90.

Step-by-step explanation:

Answer:

A = 4 11/16 or 4.6875

Step-by-step explanation:

3 3/4 = 3W

divide both sides by 3

15/4 divided by 3 = W

15/4 x 1/3 = W

5/4 = W

A = L x W

3 3/4 x 1 1/4 = 15/4 x 5/4 = 75/16 = 4 11/16

Answer:

32%

Step-by-step explanation:

136/200 broke. We want to know how many eggs out of 100 broke, so we need to set up an equivalent proportion.

136/200=x/100

Cross multiply.

13600=200x

Divide both sides by 200.

68=x

Since 68 percent broke, that means the other 32 percent survived.

Hopefully it’s correct

Answer:

1. You would divide 30 by 3 which would be 10 bags of leaves per hour.

2. You would divide 34 by 17 which would be 2 quizzes per week.

3. You would have 7 people because it says Mrs. Sapanaro and the other 6. So you divide 245 by 7 which is 35$ per person.

❆ Answer:

1. 10 bags per hour

2. 2 quizzes

3. 35 dollars per person

❆ Step-by-step explanation:

1 - divide. 30 ÷ 3 = 10

2 - divide. 34 ÷ 17 = 2

3 - divide. 245 ÷ 7 = 35

Answer:

26 5/12

Step-by-step explanation:

n − 2/3 = 25 3/4                            Add 2/3 to both sides

n - 2/3 + 2/3 = 25 3/4 + 2/3         Combine

n = 25 3/4 + 2/3

Work with the fractions

3/4 + 2/3                                      The lowest common denominator is 12

(3*3)/(3*4) = 9 / 12

(2*4)/(3*4) = 8/ 12

9/12 + 8/12 = 17/12 = 1 5/12

Now you need to add 1 to 25

1 + 25 = 26

And add the fraction 5/12

The answer is 26 5/12

Answer:

Step-by-step explanation:

Answer:

By applying law of conservation of mass.

Explanation:

Every balanced chemical equation follows law of conservation of mass.

This law states that mass can neither be created nor can be destroyed but it can only be transformed from one form to another form.

This law also states that the total number of individual atoms on the reactant side must be equal to the total number of individual atoms on the product side.

For the given reaction, the balanced chemical equation follows:

4Na1+Pb(SO4)__Pb14+2Na2SO4

On reactant side:

Number of sodium atoms = 4

Number of iodine atoms = 4

Number of lead atoms = 1

Number of sulfur atoms = 2

Number of oxygen atoms = 8

On product side:

Number of sodium atoms = 4

Number of iodine atoms = 4

Number of lead atoms = 1

Number of sulfur atoms = 2

Number of oxygen atoms = 8

Hence, the balanced chemical equation is written above.

Answer:

Options (3), (4) and (6)

Step-by-step explanation:

Coordinates of the vertices of the given rectangle are,

A(1, 5), B(3, 2), C(-3, -2) and D(-5, 1)

When rectangle ABCD is dilated by a scale factor of 2 about the origin,

Rule to be followed for the dilation,

(x, y) → (2x, 2y)

Therefore, image of the rectangle ABCD will be,

A(1, 5) → A'(2, 10)

B(3, 2) → B'(6, 4)

C(-3, -2) → C'(-6, -4)

D(-5, 1) → D'(-10, 2)

- Hence point B' is located at (6, 4).

- Rectangle ABCD and A'B'C'D' are similar as all the angles of image will be same as the pre-image after rigid transformation (dilation).

- Let the equation of the line B'C' is,

 y = mx + b

 Slope (m) = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

                  =  [tex]\frac{4-2}{6-3}[/tex]

                  = [tex]\frac{2}{3}[/tex]

 Since B'C' will pass through origin, y-intercept will be zero.

 Therefore, equation of B'C' will be,

  y = [tex]\frac{2}{3}x[/tex]

 Options (3), (4) and (6) are the correct options.
