Answer:
w=7.
Step-by-step explanation:
Divide 7 on both sides of the equation.
0.72 repeating is the sum of a geometric series with first term 0.72 and common factor 1/100. The sum is given by:
(first term) 0.72 0.72 72
--------------------------- = --------------- = ------------ = ------------
1 - common factor 1 - 1/100 99/100 99
This 72/99 can be reduced to 8/11.
0.72 repeating can be rewritten as the fraction 8/11.
B it is similar but not congurent
Answer:
$644
Step-by-step explanation:
Let X (40hrs)be the number of hours Avery works per week, and i (15%)be the raise and that her wage rate is $14/hr:
Total earnings per week is therefore:
Avery's earning per week is calculated as:
Hence, Avery's weekly earning is $644
For this one it’s 3/4. (Positive since it’s going up and you can’t simplify it anymore).
