Answer:
19/20 of a mile.
Step-by-step explanation:
![\frac{3}{10} + \frac{1}{4} + \frac{2}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B10%7D%20%2B%20%5Cfrac%7B1%7D%7B4%7D%20%2B%20%5Cfrac%7B2%7D%7B5%7D)
The common denominator is 20 so we times the first one by 2 the second one by 5 and the last one by 4. (Both numerator and denominator.)
You will end up with this ![\frac{6}{20} + \frac{5}{20} + \frac{8}{20} = \frac{19}{20}](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B20%7D%20%2B%20%5Cfrac%7B5%7D%7B20%7D%20%2B%20%5Cfrac%7B8%7D%7B20%7D%20%3D%20%5Cfrac%7B19%7D%7B20%7D)
Answer:
75% off
Step-by-step explanation:
I would personally say use a calculator, but whatever your instructor says.
First, do $600 off. You could also do 75% off first, but you choose. If you subtract $600 from $868, you get $268.
Next, do 75% off. If you take 100% - 75%, you get 25%, or 1/4. Multiply $868 by 1/4 and you get $217, which is the better deal.
So, to conclude, $217 is less than $268, and therefore 75% off is the better deal.
Answer:
60 times
Step-by-step explanation:
Since each roll has a 50% chance of rolling an even number
50% of 120 is 60
The width is w=15 ft.
The area is A=1050 sq ft.
The length of the garden is,
![\begin{gathered} L=\frac{A}{w} \\ =\frac{1050ft^2}{15ft} \\ =70ft \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20L%3D%5Cfrac%7BA%7D%7Bw%7D%20%5C%5C%20%3D%5Cfrac%7B1050ft%5E2%7D%7B15ft%7D%20%5C%5C%20%3D70ft%20%5Cend%7Bgathered%7D)
Thus, the length of the garden is 70 ft.
Y=x-5
inverse means swapping x and y
x=y-5
y=x+5
Therefore inverse function is y=x+5
