Bar over decimal means repeating
Answer:
Only one student, Melinda used it right.
Step-by-step explanation:
Associative property lets us place our brackets the way we want and the result would be unchanged.
Here: (13 + 15 + 20) + (20 + 47 + 18).
So, we can place the brackets in any form, like (13 + 15) + (20 + 20) + (47 + 18).
There are many ways to do it. Melinda's was is yet another example.
Note that Associative property does not hold for subtraction.

Hi there
Total cost of job=
Retail price of goods+labor cost+OH
First find the labor cost
Labor cost=worker A+worker B+worker C
Worker A=13×1.5=19.5
Worker b=9.5×(1+3÷4)=16.63
Worker C=5×(2+3÷4)=13.75
Total labor cost
=19.5+16.63+13.75=49.88
Overhead cost49.88×0.75=37.41
Total cost of job is
74.5+49.88+37.41=161.79
So it's option d
Hope it helps
Answer:
Mr. Ross will need 3 3/4 gallons of paint to paint the entire wall.
Step-by-step explanation:
First, multiply 142.5 by 1/5, which equals 28.5. Now you know how many square feet he painted with 3/4 of the gallon. Divide 28.5 by 3/4, or multiply 28.5 by 4/3. This equals 38, so each gallon will paint 38 square feet. Divide 142.5 by 38, and you will get 3.75. Not sure if you need to change it to a fraction or not, but if you do, it's 3 3/4.
