Answer:
21d +25 ≤ 115
Step-by-step explanation:
Jim's cost will be ...
... 21.00·d + 0.10·250 = 21d +25
He wants his cost not to exceed his budget, so ...
... 21d +25 ≤ 115
_____
The solution is ...
... 21d ≤ 90 . . . . subtract 25
... d ≤ 90/21 ≈ 4.3
so Jim can rent the car a maximum of 4 days.
There are 3 types of cost for this problem: the cost for the area covered by the tiles, cost for hourly labor and the sales tax.
Cost of Area = (10.5 ft)(8 ft)($4.75) = $399
Cost of Hourly Labor = ($22/h)(7.5 h) = $165
Sum = $399 + $165 = $564
Cost of tax = $564(0.08) = $45.12
Total Cost = $564 + $45.12 = <em>$609.12</em>
So, the amount of the bill is incorrect.
Answer:
Percent error = 6.25%
Step-by-step explanation:
Percentage error can be defined as a measure of the extent to which an experimental value differs from the theoretical value.
Mathematically, it is given by this expression;
<u>Given the following data;</u>
Experimental value = 4.5cm
Theoretical value = 4.8cm
<em>Substituting into the equation, we have;</em>
Percent error = 6.25%
I think that you that you take 17.5 and divide by 7. Then, take that answer and half it. This fulfills the area formula for a triangle, 1/2 base times height
