Hi there!

5.

Use the property:

\frac{x^a}{x^b} = x^{a - b}
Now, solve by variable.

\frac{x^2}{x} = x^{2 - 1} = x\\\\\frac{y^5}{y^4} = y^{5 - 4} = y

Rewrite:
= x * y * z^3 = \boxed{\text{ D. } xyz^3}}

6.

Solve the inside of the parenthesis, and each term separately.

Use the property:
x^0 = 1

(7 + 3^2)^0 = 1 \\\\(8^0 + 3)^2 = (1 + 3)^2 = 4^2 = 16\\\\1 + 16 = \boxed{ \text{ C. } 17}

7.

Solve like above:
(4 + 2^2)^0 = 1\\\\(7^0 + 4)^{-3} = (1 + 4)^{-3} = 5^{-3}

The negative exponent indicates taking the reciprocal. Using the property:
x^{-a} = \frac{1}{x^a}

Therefore:
5^{-3} = \frac{1}{5^3} = \boxed{ \text{ D. }\frac{1}{125}}

I think the answer is A because the data is skewed to the right 
The median (middle) isn't 10, it's 8 
The interquartile range (IQR) is 7 not 6 because you have to subtract the first and third quartile 13 - 6 = 7 not 6

Hope this helps! ;)

He truck is rented at $40 per day plus they charge per mile of use the truck travel 15 miles in one day and the total charge was
Allushta [10]

Answer:

115 = 15 x + 40

the charge is $5 dollars per mile

Step-by-step explanation:

He truck is rented at $40 per day plus they charge per mile of use the truck travel 15 miles in one day and the total charge was 115

LEt x  be  the charge in dollars per hour

Initial charge is 40 and 15 miles travelled  in one day

total charge = 15x + 40

Given : total charge is 115

So the equation becomes

115 = 15 x + 40

Now we solve for x

Subtract 40 from both sides

75= 15 x

Divide both sides by 15

x= 5

so , the charge is $5 dollars per mile
