The perimeter of a tennis court is 210 feet if the tennis court is 27 feet wide what is the length

1 answer:

6 0

You would need to multiply 27 by 2, to get the both sides or the tennis court, then you would subtract what you got from 210 in order to get the side lengths, divide that by 2 so u can get what each side is = 2

27 * 2 = 54
210 - 54 = 156
156/ 2 = 78

the side lengths of the court are 78 feet each

Find the value of X and Y

juin [17]

Well according to my calculations the image isn't exactly correct, but:

n(unknownangle) = 180 - 125 = 55

360 = 120 + 55 + 90 + x

x = 95

180 - 95 = 85
------------------
x = 95

y = 85

A print company will print business cards for $.10 each plus a setup charge of $12. Another print company offers business cards

bonufazy [111]

Let the number of cards equal x.

Set up an equation for both companies, set equal to each other and solve for x.

0.10x + 12 = 0.12x + 10

Subtractb0.10x from both sides:

12 = 0.02x + 10

Subtract 10 from both sides:

2 = 0.02x

Divide both sides by 0.02:

X = 2/0.02

X = 100

100 cards would be the same price for both companies.

10 have volunteered to help with the preparations for a party. How many ways can Susan assign someone to buy beverages, someone

Lesechka [4]

Answer:

The answer is 720 ways.

Step-by-step explanation:

Total friends who volunteered = 10

Total number of jobs that have to be done = 3

Here order matters, so it is a permutation question.

We can use the formula nPr.

= $\frac{10!}{7!}$

= 720 ways.

The second way to solve this is:

Susan can choose the first person to do a job in 10 ways

Then the second job can be done in 9 ways and the third in 8 ways.

Total becomes = $10\times9\times8=720$ ways

12-12 is 0, so -.30(12-12)^2 = 0

c(0) = 40
