Step-by-step explanation:

The line passes through the origin and point (30,3)

so, slope of the graph( miles per minute)= 3/30 = 1/10 miles per minute

Or, slope of the graph miles per hour

$= \frac{3}{ \frac{30}{60} } = \frac{3 \times 60}{30} = 6$

option B

A local car wash is open 8 hours each day. It uses 1/3 of a container of wax for each car. The car wash waxes an average of 8 1/

sweet-ann [11.9K]

Answer:

22.67 containers.

Step-by-step explanation:

The number of cars washed is the average by the total hours worked:

$C_{total}=\bar xt,\bar x=8.5,t=8\\\\C_{total}=8.5\times 8=68$

Given that each car uses 1/3 tin of wax, the total containers is calculated as:

$Containers=\bar x_c n,n=68,\bar x_c=\frac{1}{3}\\\\=\frac{1}{3}\times 68\\\\=22.67$

Hence, the car wash uses 22.67 containers of wax per day.

I don’t understand this one can someone help me?

Talja [164]

Answer:

Step-by-step explanation:

First, simplify sqrt(18/30) into sqrt(3/5). This equals (sqrt(3))/(sqrt(5)) or (sqrt(15))/5. Now, multiply it by 8 to get $\boxed{8\sqrt{15}\over5}$ or D.

Check the picture below.

well, its radius didn't change, anyhow, you know what to check out.
