Answer:
22.5 miles per hour (rounded answer)
Step-by-step explanation:
This is a fraction equal to
18 miles ÷ 0.8 hours
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 0.8
18 miles ÷ 0.8
0.8 hours ÷ 0.8
=
22.5 miles
1 hour
=
22.5 miles
hour
= 22.5 miles per hour
Answer:
there is no miles per hour because she wasn't riding for an hour

Step-by-step explanation:
The expression "f-9" can be interpreted in different ways depending on the context. 1. If "f" represents a variable or function, and you are asked to evaluate "f-9", it means you need to subtract 9 from the value of "f". For example, if f = 15, then f-9 would be 15-9 = 6. 2. If "f" is a specific function or formula, and you are asked to simplify "f-9", it means you need to simplify the expression "f-9" as much as possible. Without further information about the specific function or formula, it is difficult to provide a specific answer. However, you can follow general rules of simplifying expressions, such as combining like terms or applying mathematical operations. 3. If "f" is a placeholder for a specific numerical value, and you are asked to evaluate "f-9", you need to substitute the value of "f" into the expression and then subtract 9. For example, if f = 7, then f-9 would be 7-9 = -2. In summary, the meaning of "f-9" depends on the context and how "f" is defined. It could represent subtraction of 9 from a variable or function, simplification of an expression involving "f" and 9, or evaluation of an expression where "f" represents a specific numerical value.
Answer:
To calculate how much time you spend on each activity, you need to fill in the circle with everything you do in a day, using 24-hour format1. For example, if you sleep for 8 hours, work for 4 hours, and study for 3 hours, you can write these numbers in the circle. Then, you can add up the hours for each activity and write them in the table below.
Here is an example of how to fill in the circle and the table:

ACTIVITIES BREAKDOWN - Hours per week
1. Class Time: 0
2. Study Time, reviewing, projects, papers: 3 x 7 = 21
3. Commuting: 0
4. Dressing and eating: 1 x 7 = 7
5. Hours of employment: 4 x 5 = 20
6. Responsibilities at home: 1 x 7 = 7
7. Athletics requirements: 0
8. Telephone and computer: 2 x 7 = 14
9. Television: 1 x 7 = 7
10. Sleeping: 8 x 7 = 56
11.
12.
13. Wasted hours:
Total: (21 + 7 + 20 + 7 + 14 + 7 +56) =132
Total number of hours per week =168
Subtract your Total (132)
Total free hours per week = (168 -132) =36
