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.

ZanzabumX [31]

Answer:5 + /- sqrt35

Step-by-step explanation:

Rearranging, we get x^2 -10x -10=0

Applying the quadratic formula,

(10 +/- sqrt(10^2 -4*-10))/2

(10+/- 2sqrt35) /2 = 5 + /- sqrt35 as the two roots.

12 x - 13 - x - 9 = 10x = ?
SIZIF [17.4K]

Problems:                                                              Answers:

12 x - 13 - x - 9 = 10x                                              x = 22

-15k - 1 + 12 + 2k                                                    k = 11/13

10a - 7b + 11 + 8a - b - 12                                       b = (9 a)/4 - 1/8

7a^2 + 10a - 3a - 2a^2                                           a = -7/5

-c + 5d + 7c - 11d + d - 3c                                      d = (3 c)/5

x^2 - 3xy - 5xy - 7y^2 + 4x^2 + 8y^2                    y = 4 x - sqrt(11) x

Plz solve all:<br><br> 4x+3−9x=<br><br> 5+3.2n−6−4.8n=<br><br> 2y−5(y−3)<br><br> −1/2(8b+3)+3b=
pashok25 [27]

Answer:

4x+3−9x= 3-5x

5+3.2n−6−4.8n= -1.6n-1

2y−5(y−3)= -3y-15

−1/2(8b+3)+3b= -1b-1.5

Step-by-step explanation:

Add the numbers with the variables.

4x-9x= -5x

Then add the rest of the equation to it.

3-5x

Again, add the numbers with the variables and simplify the others.

3.2n- 4.8n= -1.6n

5-6= -1

That leads to....

-1.6n-1

Distribute the 5 into the parenthesis.

2y-5y- 15

Now, subtract the variables.

-3y-15

Distribute into the parenthesis.

-4b+(-1.5)+ 3b

Add the variables together.

-1b-1.5

Jobisdone [24]
When you graph an equation, it should be dependent variable against the independent variable. For this problem, the independent variable is the time, so this is along the x-axis. The dependent variable is d, so this is along the y-axis. Since the slope is Δy/Δx, then it is also equivalent to Δd/Δt. Therefore, the answer is B.
