Remember, the exact value cannot involve any rounding or estimates. Now, let's solve this problem. First, we have to translate it into an expression:
√72 - √8 + √128 separate the terms into square roots
√36·2 - √4·2 + √64·2 square root the terms that you can
6√2 - 2√2 + 8√2 they have like radical terms, so combine the terms
6 - 2 + 8 = 12 the coefficients are 12 when combined
12√2 this is the EXACT VALUE of the expression
Hope this helps!
First find how they got 10 inches out of 25 centimeters.
25/10 = 2.5
This means that they divided 25 by 2.5 to get 10, and this pattern will continue throughout the whole table.
105 × 2.5 = 42
There are about 42 inches in 105 centimeters.
Another way to do this is there are 0.39 inches in 1 centimeter.
105 × 0.39 = 40.95
This rounds to 41.
This answer is probably better.
Answer:
Maureen earned $123.19 doing odd jobs
Step-by-step explanation:
The compound interest formula is given by:

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per unit year and t is the time in years for which the money is invested or borrowed.
In this question:
Compounded quarterly means that 
10 years, so 
9% interest, so 
There is $300.00 in the account, which means that 
How much did Maureen earn doing odd jobs?
This is P.
