Given :

Admission price , A = $15 .

Price of each ride , p = $3 .

Number of rides , r = 3 .

To Find :

Total money spend if he goes on 5 rides and for r number of rides .

Solution :

Let , total amount paid is P .

First we find the general equation :

Total \ amount = Admission\ Fee - r\times ( Fee\ per\ ride )

P=15+3r

Now , for r = 5 , total price is :

P=15+3\times 5\\\\P=15+15=\$30

Hence , this is the required solution .

Given angle ABC shown on the coordinate plane below.
Crank

The attached image shows the image of A"B"C" after the transformation

<h3>What is the transformation of the triangle about?</h3>

The transformation rule states:

A"B"C" = Ro90° (T(-4,3)(ABC))

This implies that one need to rotate the triangle in a 90⁰ clockwise direction, and then one need to translate the triangle.

Using the image shown, the coordinates of ABC are;

A = (-1, 2)

B = (1, 4)

C = (3, -1)

The 90⁰ rule clockwise rotation  will be:

(x,y) -- (y,-x)

So, when translated, it will be:

A' = (2, 1)

B' = (4, -1)

C' = (-1, -3)

Then the translation of the triangle using T(-4,3):

(x, y) -  (x - 4, y + 3)

So, there is:

A'' = (-2, 4)

B'' = (0, 2)

C'' = (-5, 0)

How the equation y=7.5x + 50 shows the slope and the y-intercept
iris [78.8K]

Answer:

slope:7.5, y-intercept:50

Step-by-step explanation:

The basic equation for slope is y=kx+b

In this equation, k stands for slope and b stands for y-intercept.

So in y=7.5x+50, k is 7.5 and b is 50 which equal to slope is 7.5 and y-intercept is 50

A mail carrier can deliver mail to 36 houses in 30 minutes. Mark wants to determine how many houses the carrier can deliver mail
sergey [27]

Answer:

Mark’s method is correct, because even though it is impossible to deliver mail to 1.2 houses in a minute, 1.2 represents the unit rate of houses per minute.

Step-by-step explanation:

Let's rule out the options given one by one.

Option 1: Mark’s method is wrong, because it is impossible to deliver mail to 1.2 houses in a minute. The carrier can only deliver to a whole number of houses.

This is not true, because 1.2 is a rate, it just means that the carrier can finish 1 house in a minute, and also have time to get started delivering to the second house. The total number of houses has to be a whole number, but the rate doesn't.

Option 2: Mark’s method is wrong, because it is impossible to deliver mail for 7.5 minutes. The carrier can only deliver mail for a whole number of minutes.

This option is also incorrect. Delivering mail for 7.5 minutes just means 7 minutes and 30 seconds, which is definitely possible.

Option 3: Mark’s method is correct, because even though it is impossible to deliver mail to 1.2 houses in a minute, 1.2 represents the unit rate of houses per minute.

This option is correct. 1.2 is the rate of which the carrier delivers mail.

Option 4: Mark’s method is correct, because it is possible to deliver mail for 7.5 minutes; 7.5 represents the unit rate of 7.5 minutes per house.

This option is also incorrect. Although it is possible to deliver mail for 7.5 minutes, it is not the unit rate, it is the total amount of time it would take.

Please simplify n-2/n^2-4
Doss [256]

Answer:

\frac{1}{ {n}   +   {2}}

Step-by-step explanation:

\frac{n - 2}{ {n}^{2}  - 4}  \\  \\  =  \frac{n - 2}{ {n}^{2}  -  {2}^{2} } \\  \\  = \frac{n - 2}{ ({n}   +   {2})({n}  -  {2})} \\  \\  =  \frac{1}{ {n}   +   {2}} \\
