Answer:

Step-by-step explanation:
Note the number 5 is repeated 4 times, hence we can say that the expression 5⋅5⋅5⋅5 is equivalent to 5 raised to the power of 4 or 
edit : correct spelling
Lets use the formula
to solve this, where,
- R is the rate
- W is the number of workers/things
- T is time
- J is number of jobs/things
<em><u>"If it takes 10 seconds for 10 printers to print out 10 pages of paper"</u></em> - here -
W is 10 printers, T is 10 seconds, and J is 10 pages. We can write:

<u><em>"how many seconds will it take 50 printers to print out 50 pages of paper"</em></u><em> - here we use
(previously found) to figure out T.</em>
<em>
</em>
So it will take 10 seconds for 50 printers to print 50 pages.
ANSWER: 10 seconds
The general equation of a line is y = mx + b
m is given as 1/2, so we have:

Plugging in the given values of x and y, we get:
-2 = 0 + b
Therefore b = -2, and the answer is:
Answer: C
Step-by-step explanation:
13-3=10
750 - 405 = 345
345 divided by 750 x 100
