Answer:

The answer to your question is: rate charged by

Mechanic 1 = $95

Mechanic 2 = $ 115

Step-by-step explanation:

Data

mechanic 1 = 10 hours  = x

mechanic 2 = 15 hours = y

total charged = $2675

rate charged per hour = ?

sum of the two rates = $210

Write equations

                             x + y = 210                       (I)

                          10x + 15y = 2675                (II)

Solve the equations by elimination

Multiply I by -10

                           -10x - 10y = -2100

                            10x + 15y = 2675                Add the equations

                              0   + 5y = 575                  Find y

                                        y = 575/5          

                                       y = $ 115   Mechanic 2

Find x

                       x + 115 = 210

                       x = 210 - 115

                      x = $95              Mechanic 1

In the attachment count the shaded, and the total amount make it to a fraction, and then simplify to make it to a percentage
Alisiya [41]

Answer:

30/75  2/5

Step-by-step explanation:

there are 30 shaded squares, and a total of 75 squares. Therefore the fraction is 30/75.   This can be simplified to 2/5 if both sides are divided by fifteen.

To make a percentage, simply divide 2 by 5 which equals 0.4 = 40%

The midpoint of K is M(-3, -1). One endpoint is J(-12, -11). What are the coordinates of endpoint K?
Over [174]

Answer: 2 times sqrt(181) (approximately 26.9)

Step-by-step explanation:

First, we can plot these points on a graph. Then, we’ll use the Distance Formula to calculate the distance between the two points, which is sqrt(181).


Since the problem tells us that one of our coordinates is the midpoint of K, we know that the length of the segment we just calculated is 1/2 of K. We can multiply our answer to get that K is 2 times sqrt(181).

Julli [10]

This question is incomplete, the complete question is;

Lets consider a hypothetical airline, Mudlark Airlines. On one of its flight, previous records show that about 15% of people who had tickets for the flight did not take the flight. There are 120 seats on the plane.

Suppose that Mudlark decides to sell 140 tickets for this flight. Assuming that all 140 tickets are sold and that the outcome for each ticketholder is independent, how many ticketholders should the airline expect to show up

Answer: the airline should expect 119 ticketholders to show up

Step-by-step explanation:

Given that;

the plane contains 120 seats

Their records shows that 15% (0.15) percent of people who previously buy their flight tickets don't show up.

they sold 140 tickets,

Number of ticketholder expected to show up  = ?

Probability of showing up for flight will be;

⇒ 1 - 0.15 = 0.85

Now Expected number of ticketholders to shup will be;

⇒ 140 × 0.85

= 119

Therefore the airline should expect 119 ticketholders to show up
