Math assignment = 3/8 hours
History assignment = 1/4 hours
We can not compare this as both fractions do not have alike denominators.
We can fix this problem easily by turning 3/8 and 1/4 into alike denominator fractions.
We can turn 1/4 into 2/8 as it is equivalent fractions.
1 x 2 = 2
4 x 2 = 8
(Whatever you do to the denominator, you have to do the same to the numerator)
Once we get this, we can see that Shen spent 2/8 hours on his homework while he spent 3/8 hours on his math assignment.
3/8 - 2/8 = 1/8
1/8 = 0.125
Shen spent 1/8 of an hour (or 0.125 of an hour) more on his math assignment than his history assignment.
Answer:
D
Step-by-step explanation:
the median is the middle value of a data set in ascending order
If there is not an exact middle then it is the average of the values on either side of the middle
Arrange data in ascending order
15, 17, 19, 21, 23, 25, 26, 28, 28, 30
the middle is between 23 and 25 , hence
median = 
= 
= 24
Answer:
m=rise over run
so it would be 
Step-by-step explanation:
Answer:
(12/1.35)^2 ~= 79.012346
(roughly equal to ~=)
Step-by-step explanation:
divide both sides by 1.35
12/1.35 = √x
square both sides to get rid of √
(12/1.35)^2 ~= 79.012346
Answer:
The answer is 36 adults and 88 children.
Step-by-step explanation:
The two equations are:
x+y=124 and 5x+3y=444
Using substitution method:
5x+3(124+x)=444
5x+372-3x=444
2x=72
x=36
5(36)+3y=444
180+3y=444
3y=264
y=88
