Answer:

Crew B's data shows a proportional relationship.

Step-by-step explanation:

This is because the constant of proportionality in each example given ($315 and 3 hours, $525 and 5 hours, $735 and 7 hours), is the same number with all of the values, which is 105. You can find this by dividing the dependant variable by the independent variable (In this case the money earned is dependant and the number of hours worked is independent).

En una cancha se va a pintar la circunferencia central que tiene un diámetro de 5 m .¿cual es la longitud de la circunferencia?
Alona [7]

Answer:

The length of the circumference is 5\pi\ m  or 15.70\ m

Step-by-step explanation:

<u><em>The question in English is</em></u>

On a court, the central circumference will be painted, which has a diameter of 5 m. What is the length of the circumference?

we know that

The circumference of a circle is given by the formula

C=\pi D

we have

D=5\ m

substitute

C=\pi (5)\\C=5\pi\ m

This is the exact value

assume

\pi=3.24

C=5(3.14)=15.70\ m

Mr. Malone is contemplating which chauffeured car service to take to the airport. The first costs $28 upfront and $2 per mile. T
Ksju [112]

Answer:

The distance is 8 miles.

Step-by-step explanation:

First, we need to write an equation for each of chauffeured car services.

The first one = 28 + 2x = ?

The second one = 13 + 5x = ?

Next, we need to figure out what x is. Usually I just plug in random numbers, but I'm sure there's a better way to do it.

I first plugged in 2 as x.

28 + 4 = 32

13 + 10 = 23

That didn't work, so I then plugged in 5.

28 + 10 = 38

13 + 25 = 38

So 5 would be the correct answer for what is the distance.

Which of the following equations describes the graph shown?
Darya [45]
By looking at the slant at which the line is going, you can tell if the line is negative or positive. This line is negative, so that removes two of the choices. By looking at where the line intersects the y-axis determines if its negative or positive. So the answer is D

Hello from MrBillDoesMath!

Answer:

y = x/15


Discussion:

Given:

2x/5y = 6  =>          (multiply both sides by 5y)

(2x/5y) 5y = 6 * (5y) =>

2x = 30y =>            (divide both sides by 30)

(2/30)x = y =>

y = x/15


( or you could also multiply both sides of the original equation by "y" and then divide both sides by 6)

Thank you,

MrB
