Answer:
The equation representing pounds of apples will has left
.
Will has left with 7 pounds of apples.
Step-by-step explanation:
Given:
Total pounds of apple = 20 pounds.
Pounds of apple used for apple sauce = 4 pounds
Pounds of apple used for apple butter = 6 pounds
Pounds of apple used for making juice = 3 pounds
We need to write the equation to represent pounds of apples will has left.
Solution:
Let us assume pounds of apples will has left be 'x'.
So we can say that;
pounds of apples will has left can be calculated by subtracting Pounds of apple used for apple sauce and Pounds of apple used for apple butter and Pounds of apple used for making juice from Total pounds of apple.
framing in equation form we get;
![x=20-4-6-3](https://tex.z-dn.net/?f=x%3D20-4-6-3)
Hence The equation representing pounds of apples will has left
.
On Solving the above equation we get;
![x=7\ pounds](https://tex.z-dn.net/?f=x%3D7%5C%20pounds)
Hence Will has left with 7 pounds of apples.
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,
![n=24\times 365](https://tex.z-dn.net/?f=n%3D24%5Ctimes%20365)
In scientific notation,
![8760=8.760\times 10^3](https://tex.z-dn.net/?f=8760%3D8.760%5Ctimes%2010%5E3)
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,
![n=\frac{31556952}{3600}](https://tex.z-dn.net/?f=n%3D%5Cfrac%7B31556952%7D%7B3600%7D)
![n=8765.82](https://tex.z-dn.net/?f=n%3D8765.82)
In scientific notation,
![8765.82=8.76582\times 10^3](https://tex.z-dn.net/?f=8765.82%3D8.76582%5Ctimes%2010%5E3)
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.
