In the given question, there are several important information's that needs to be noticed. based on these information's the correct answer to the question can be easily deduced. It is already known that the contestants rest for the same amount of time every hour. In 6 hours they rest for 27 minutes. The 6 hours has to be converted to minutes first.
Then 6 hours = (6 * 60) minutes
                       = 360 minutes
So we have to first determine the amount of rest each contestants take in 1 hour.
Then
In 360 minutes the couple rests for a total time = 27 minutes
In 60 minutes the couple will rest for = (27/360) * 60
                                                           = 4.5 minutes
So the couple rests for 4.5 minutes in 1 hour
Then
In 8 hours the couple will rest for = (8 * 4.5) minutes
                                                     = 36 minutes.
The couple will rest for 36 minutes in 8 hours.

kogti [31]
Let's define variables:
 x = Rate in $ / hr of the mechanic working 15hr
 y = Rate in $ / hr of the mechanic working 5hr
 We have the following system of equations:
 x + y = 130
 15x + 5y = 1400
 Solving the system we have:
 x = $ 75 / hr
 y = $ 55 / hr
 Answer:
 
the rate charged per hour by mechanics was:
 
x = $ 75 / hr
 
y = $ 55 / hr

The points given in the table above lie on a line. Find the slope of the line.
pantera1 [17]

Answer:

Step-by-step explanation:

When given points, whether that be on a graph or a table, those can be used to find the slope using the equation y2 - y1 / x2 - x1.

y2 - y1 / x2 - x1

(Pick 2 pairs if points. In this case I am using (2, -1) and (-1, 3) from your data table. From here, just plug it in.

-1 - 3 / 2 + 1

-4 / 3

Your slope is -4/3. Hope that helps! Take care.

In triangle abc, if A=120 degrees, a=8 and b=3, then angle B=
CaHeK987 [17]

The angle of B is \angle B=19^{\circ}

Explanation:

It is given that \angle A=120^{\circ} and a=8, b=3

To determine the \angle B, let us use the law of sine formula.

Thus, we have,

\frac{Sin A}{a} =\frac{Sin B}{b}

Substituting the values in the formula, we have,

\frac{Sin 120}{8} =\frac{Sin B}{3}

Multiplying both sides by 3,we get,

\frac{3(0.866)}{8} ={Sin B}

Simplifying and dividing, we get,

0.32475=Sin B

Multiplying both sides by \sin ^{-1}, we get,

\sin ^{-1}(0.32475)=B

Thus, B=18.95^{\circ}=19^{\circ}

Hence, The angle of B is \angle B=19^{\circ}
