The diameter of a tire is 2.5 ft. Use this measurement to answer parts a and b. Show all work to receive full credit.

A. Find the circumference of the tire.
B. About how many times will the tire have to rotate to travel 1 mile? (1 mile = 5,280 ft)

Answers

Answer:

Answer Below

Step-by-step explanation:

The diameter of a tire is 2.5 ft. a. Find the circumference of the tire. b. About how many times will the tire have to rotate to travel 1 mile?

a) The circumference of a circle is the perimeter of the circle. The circumference of the circle is the distance around a circle, that is the arc length of the circle. The circumference of a circle is given by:

Circumference = 2π × radius; but diameter = 2 × radius. Hence:

Circumference = π * diameter.

Given that diameter of the tire = 2.5 ft:

Circumference of the tire = π * diameter = 2.5 * π = 7.85 ft

b) since the circumference of the tire is 7.85 ft, it means that 1 revolution of the tire covers a distance of 7.85 ft.

1 mile = 5280 ft

The number of rotation required to cover 1 mile (5280 ft) is:

number of rotation = 5280 ft/7.85 ft per rotation = 672 rotations.

The point (5, -1) is reflected over the
x-axis. What are the new coordinates?
A. (-5, 1)
B. (-5, -1)
C. (5, 1)
D. (-1,5)

Answers

Answer:

c

Step-by-step explanation:

when reflected across the x-axis the x becomes  negative and vise versa

when reflected across the y axis the y becomes negative and vise versa  

The new coordinates will be  [tex](5,1)[/tex] .

What are coordinates ?

Coordinates determine the position of the points or other geometric elements on graph.

We have,

Point [tex](5, -1)[/tex].

Reflected over x-axis,

So,

If a point [tex]( x,y)[/tex] under a reflection on the x-axis will be [tex](x,-y)[/tex] .

So,

according to the above mentioned statement,

Point [tex](5, -1)[/tex] reflected on the x-axis

We get ,

Reflected point [tex](5,1)[/tex] .

So, the new coordinates are  [tex](5,1)[/tex] .

Hence, we can say that the new coordinates will be  [tex](5,1)[/tex] .

Megan wants to give each guest at her birthday party three mini-
cans of Play-Doh. The cans are sold in bags of nine for $2.86. If there
are thirty-six guests at her party, how much will it cost to give three
mini-cans of Play-Doh to each guest?

Answers

36 x 3 = 108 so you need 108 cans of mini play dough. 108 divided by 9 is 12 so you need 12 bags. 12 x 2.86 is 34.32. It will cost $34.32 to buy 108 cans of mini play dough and give 3 to each of your 36 guests

Number of guests to be invited in the birthday party = 36

Megan wants to given 3 cans of Pay-Doh to each guest.

Therefore, number of cans to be given = 3 × 36 = 108

Since, cans are sold in the pack of 9, number of packs required = [tex]\frac{108}{9}[/tex]

                                                                                                           = 12

Since, cost of each pack of cans = $2.86

Therefore, total cost of 12 packs = 12 × 2.86

                                                       = 34.32

Jayden used a Groupon at the local pizza shop. Instead of paying $15, for the pizza, he paid $12.

Haley and Arianna agree that the percent of decrease is 20% but their explanations differ. Haley says to find the 20%, you have to determine what percent of 15 is 12. Arianna thinks you have to determine what percent of 15 is 3. Who is correct? Explain your thinking.

Answers

Answer:

She is correct because they need to find how much is the discounted price, which is 3. So to see what percentage it is, they need to see how much 3 is worth in comparison to 15. If we spilt 15 into 5 parts to make every part worth 20%, the answer would be 3. Thus Arianna is correct.

William gets a student loan to pay for his college tuition. He borrowed $2,500 for 10 years at an interest rate of
8%. How much will William pay in interest on this loan?

Answers

Answer:

2897.31

Step-by-step explanation:

I'm going to assume two things

The interest rate is compoudning annually

There is only one payment (at the end of the 10 years)

To find the amount of interest paid on this loan we first need to calculate the future value (or accumulated value)

FV=PV(1+i)^n

Plug in our numbers

2500(1+.08)^10

Run this through a calcuatlor and get 5,397.31

This is the future value and the question is asking for the interest paid which is just the FV-PV

Which means we have

5,397.31-2500

our answer is 2897.31

HELP You are on the Pirates of the Caribbean attraction in the Magic Kingdom at Disney World. Your boat rides through a pirate battle, in which cannons on a ship and in a fort are firing at each other. While you are aware that the splashes in the water do not represent actual cannonballs, you begin to wonder about such battles in the days of the pirates. Sup-pose the fort and the ship are separated by 75.0 m. You see that the cannons in the fort are aimed so that their cannon-balls would be fired horizontally from a height of 7.00 m above the water. (a) You wonder at what speed they must be fired in order to hit the ship before falling in the water. (b) Then, you think about the sludge that must build up inside the barrel of a cannon. This sludge should slow down the cannonballs. A question occurs in your mind: if the can-nonballs can be fired at only 50.0% of the speed found ear-lier, is it possible to fire them upward at some angle to the horizontal so that they would reach the ship?
