daily math practice monday 5

1. 5.29 + 6.73 =
2. $\begin{array}{r}6.29\\+9.68end{array}$
3. what is the median of this data?

4, 6, 7, 9, 10, 12, 14, 15, 15

1. how many quarts are in a gallon?
2. brandon is half as old as his brother ryan. ryan is one - eighth the age of his father. if their father is 32 years old, how old are ryan and brandon?

Explanation:

Step1: Add 5.29 and 6.73

$5.29 + 6.73=12.02$

Step2: Add 6.29 and 9.68

$6.29+9.68 = 15.97$

Step3: Find median of data set

The data set $4,6,7,9,10,12,14,15,15$ has 9 numbers. The middle - numbered value is the 5th one. So the median is 10.

Step4: Recall volume conversion

There are 4 quarts in a gallon.

Step5: Calculate Ryan's and Brandon's age

If the father is 32 years old, and Ryan is one - eighth the age of his father, then Ryan's age is $\frac{32}{8}=4$ years old. Since Brandon is half as old as Ryan, Brandon's age is $\frac{4}{2}=2$ years old.

Answer:

1. $12.02$
2. $15.97$
3. $10$
4. $4$
5. Ryan is 4 years old, Brandon is 2 years old.
