Answer:
The percent error of Heather's calculation is <u>8%</u>.
Step-by-step explanation:
Given:
Heather measures the temperature of her coffee to be 133.4 degrees fahrenheit. It is actually 145 degrees fahrenheit.
Now, to find the percent error of Heather's calculation.
The temperature of coffee Heather measures = 133.4° F.
Coffee's actual temperature = 145° F.
So, to get the measurement in error we subtract the temperature of coffee Heather measures from coffee's actual temperature:
![145-133.4=11.6\°.](https://tex.z-dn.net/?f=145-133.4%3D11.6%5C%C2%B0.)
Now, to get the percent error:
![\frac{11.6}{145}\times 100](https://tex.z-dn.net/?f=%5Cfrac%7B11.6%7D%7B145%7D%5Ctimes%20100)
![=\frac{1160}{145}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1160%7D%7B145%7D)
![=8\%.](https://tex.z-dn.net/?f=%3D8%5C%25.)
Therefore, the percent error of Heather's calculation is 8%.
<h3>
Answer: 13,011.11 dollars</h3>
note: remember to take the comma out or ignore it. I put it in there to help make the number more readable
===========================================
Explanation:
Let x be the value of the sale in dollars.
x-1900 represents the leftover amount that is over 1900
eg: if x = 2200, then x-1900 = 2200-1900 = 300 is the the leftover amount
taking 9% of (x-1900) leads to the expression 0.09(x-1900) and this expression must be 1000 since this is the extra amount of money the salesman needs (he already has $1000 in base pay)
-------------
Solve for x
0.09(x-1900) = 1000
x-1900 = 1000/0.09
x-1900 = 11,111.11111 approximately
x = 11,111.11111 + 1900
x = 13011.1111
x = 13,011.11 rounding to the nearest cent
The answer would be 16.
8+8=16
G(x)=|x+3|-5
down five units means add -5 to then end of the equation
