Answer:

48 yards

Step-by-step explanation:

we know that

The circumference of a circle is equal to

C=2\pi r

we have

r=7.6\ yd\\\pi=3.14

substitute

C=2(3.14)(7.6)=48\ yd

Answer: 48 yards

Step-by-step explanation:

The circumference of a circle can be calculated with the following formula:

C=2\pi r

Where "C" is the circumference of the circle and "r" is the radius of the circle.

In this case you know that the radius of the circular track is the following:

r=7.6\ yd

Knowing tha radius, you can substitute it into the formula (According to the information given in the exercise, you need to use \pi =3.14)

C=2(3.14)(7.6\ yd)

Finally, you need to evaluate.

Therefore, you get that the whole yards of fencing that they need to purchase to enclose the track is:

C\approx48\ yd

You need to rent a video camera for your school project. Murphy's Camera charges a $30 rental fee plus $35 per day. Allied Renta
andreev551 [17]

A. If a camera is rented for 1 or 2 days, it would be logical to rent it from Murphy's.

B. If a camera is needed for more than 3 days, it would make sense to rent it from Allied rental.

C. Yes, if a camera is rented for 3 days both rentals charge the same money.

C. If you were need a camera for 3 days, you would have to pay $135 for both stores.

<u>Step-by-step explanation:</u>

Step 1; Murphy's camera costs $30 to rent and an additional $35 for each day of rental. So the equations are

y = $30 + (x × $35), where y is total cost and x is the number of days rented.

So for x = 1, y = $30 + (1 × $35) = $30 + $35 = $65

So for x = 2, y = $30 + (2 × $35) = $30 + $70 = $100

So for x = 3, y = $30 + (3 × $35) = $30 + $105 = $135

So for x = 4, y = $30 + (4 × $35) = $30 + $140 = $170

So for x = 5, y = $30 + (5 × $35) = $30 + $175 = $ 205.

Step 2; Allied rental costs $45 to rent and a $30 for each day of rental. So the equations are as follows

y = $45 + (x × $30), where y is total cost and x is the days rented

So for x = 1, $45 + (1 × $30) = $45 + $30 = $75

So for x = 2, $45 + (2 × $30) = $45 + $60 = $105

So for x = 3, $45 + (3 × $30) = $45 + $90 = $135

So for x = 4, $45 + (4 × $30) = $45 + $120 = $165

So for x = 5, $45 + (5 × $30) = $45 + $150 = $195

Step 3; Comparing both prices over 5 days. Murphy's is cheaper for until 2 days. On day 3 both the rentals cost the same but after day 4, allied rentals is the better option.
