First, add all of the working hours.
1
+ 2
+ 1
Since the denominators are different, make them all the same.
1
+ 2
+ 1
Add everything together.
4
+ 1
= 5
Then, simplify.
5
or 5.5
Multiply the time by the salary.
<span>5.5*10.5=
Doug earned $57.75</span>
15+10
i believe this is right
we are given
Number pages=8
Time taken =12 minutes
so, ratio = ( number pages)/(time taken)
so, we get
now, we can simplify it
we can factor numerator and denominator
now, we can cancel common terms
So, simplest form is
..............Answer
The answer is B because it is 7 zeros behind the decimal and when you swoop 8 times left, you get 0.0000000398.
