Answer:
B
Step-by-step explanation:
Let's eliminate the incorrect answers. C and D are incorrect, since anything to the power of 0 is equal to 1. A is incorrect, because -1 * -1 = 1 since the negatives cancel out. B is correct, because -1*-1*-1*-1*-1 has an odd number of negatives, and thus you are left with -1 instead of 1. Therefore, the answer is B.
-38(-3) = 114
-72/(-12) = 6
-9 x 23 = -207
-150/5 = -30
564 / -4 = -141
<h3><u>Solution:</u></h3>
Given that, we have to find each product or quotient
<em><u>-38(-3)</u></em>
It is a product, so we have to find product value

<em><u>-72 / (-12)</u></em>
It is division, so we have to find the quotient

<em><u>-9 x 23</u></em>
It is a product, so we have to find product value

<em><u>- 150 / 5</u></em>
It is division, so we have to find quotient

<em><u>564 / -4</u></em>
It is division, so we have to find the quotient

Answer:
Elbert will Make $968 in 40 hours of work with the raise.
Step-by-step explanation:
Given:
Elbert makes $22 an hour.
He got 10% raise
Money raised on 10% =
Now total money for per hour after raise = 
Now to find the total money earned after 40 hours with raise we need to multiply total money for per hour after raise with number of hours.
Total money earned = 
Hence, Elbert will Make $968 in 40 hours of work with the raise.
Given that the ball was rolling with an initial velocity of 4.80 m/s, when it encountered the ramp.
Given that the accerelation with which it rolled over the ramp was

and that the ranp is 0.750 m long.
The final velocity of an object with an initial velocity, u, with an accerelation, a, moving through a distance, s is given by

Thus, the <span>final velocity of the ball when it reaches the top of the ramp is given by
