Answer:
138 miles
Step-by-step explanation:
You would have to find the difference between $18.95 and $155.57. When you find the total which is $136.62, you would need to divide it by $0.99. That is what will give you the number of miles that Teeth drove.
4 1/2-3 5/8=0.875 or 875/1000 or 35/40 or 7/8
Answer:
564 pencils
Step-by-step explanation:
1 box = 12 pencils

300 + 264 = 564 pencils
Answer:
I) There are
hours in 1 year.
II) The exact number of hours in one year is
hours.
Step-by-step explanation:
Given : 1 hour=3600 seconds
1 year = 31556952 seconds.
To find :
I) Use scientific notation to estimate the number of hours in one year.
1 day = 24 hours
1 year = 365 days
So, number of hours in one year is given by,

In scientific notation,

So, there are
hours in 1 year.
II) 1 year = 31556952 seconds.
1 hour = 3600 seconds
In one year the number of hour is given by,


In scientific notation,

So, the exact number of hours in one year is
hours.
III) In two or more complete sentences, compare your answers to parts I and II. In your comparison, discuss similarities and differences.
- The exact numbers of hours using 365 days is 8760 which is written as
in scientific notation but using the given data we get
hours.
- Comparing these answers the first one has only 3 significant figures and the second answer has six significant figures.
- If we round these we get
hours which has two significant numbers.
Answer:
6 laps
Step-by-step explanation:
According to the scenario, calculation of the data are as follows:
Each lap = 0.25 miles
Regan's plan to run= 1.5 miles
So, we can calculate number of laps by using following formula,
Number of laps = Total miles to run ÷ each lap miles
By putting the value, we get
Number of laps = 1.5 miles ÷ 0.25 miles
= 6 laps
So, she should run 6 laps.
