Answer:
7h=63 so a because she charges $7 per hour and earned a total of $63
0.50
imagine it like a dollar.
1/4 of a dollar is 0.25
meaning 2/4 is 0.50
Answer:
Mode = 19.
Median = 23.
Step-by-step explanation:
Arrange in ascending order:
8 9 12 15 17 18 19 19 20 22 24 25 26 27 28 31 34 36 40 43
The modal amount is the one which occurs most , which is 19.
The median is the middle value of the 20 amounts.
As there is an even number of amounts the median is the mean of the 2 middle numbers:
Median = (22 + 24) / 2
= 23.
Let the two ages be j and m, respectively. Then j+m>32.
Solving for Mary's age, we get m > 32 - j. Because j = m + 2, m > 32 - (m+2).
Continue solving for m: Adding m to both sides of this inequality results in
2m > 32 - 2. Then 2m > 30, and m > 15. Mary's age is greater than 15.
