X=-14
do you want an explanation <span />
Answer:
Step-by-step explanation:
If Kyle can get 5/8 of a shed built in x amount of time, he can get 62.5% done; if Jack can get 1/5 of the shed built in the same time, he can 20% of it done. As a ratio:
Kyle gets the whole thing done, 100% of the way, leaving Jack lagging behind at a somewhat lower percentage of the work being done.
and cross multiply to solve for the percentage of the shed built by Jack by the time Kyle gets it completed:
62.5x = 2000 so
x = 32%
Hello wonderful person!!
Okay, so first of all, welcome to brainy
Second, you have to determine whether they are equal to each other and are the same. For example, if i say 2/4 is equal to 4/8, it's considered proportional.
Hope you understand this, and have a GREAT day!! :)
Answer:9 to 4 is 7 hrs divide 7 into 28.84 you get 4.12 so answer is $4.12 an hour
Step-by-step explanation:
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.
