The Circumference Of A Circle Is 23 Pi M What Is The Area In Square Meters Express Your Answer In Terms

Answers

Answer 1

Answer:132.25π  m²

Step-by-step explanation:The circumference of a circle is 23π

On the other hand, The circumference of a circle = 2×π×r ; where r is the radius. Then by equating the last two expressions we get: 23π = 2πr then r = 23/2 then the area = π × r² = (23/2)²×π = (132.25)×π

jenny has $55 in her checking account, he bought 7 equally priced dvds and paid with a check. her new account balance is -$22. how much was each dvd?

Answers

Answer:

Jenny spent $11 on each dvd she bought.

Step-by-step explanation:

First and foremost, add 55 and 22 since her account balance is now at -$22 since that shows she spent even more.

55+22= 77

Next step divide 7 into 77 since that's how many dvds jenny bought.

77÷7= 11

The answer is $11. Jenny spent $11 on each dvd she bought.

Hope this helps

Find an ordered pair (x,y) that is a solution to the equation.
5x+y=6

Answers

Answer:

(0,6) and (1.2 , 0)

Step-by-step explanation:

5x + y = 6

if we take x=0

5(0) + y = 6

y = 6            ; so, one of the solution is (0,6)

if we take y=0

5x + (0) = 6

5x = 6

x = 6/5 = 1.2     ; so, the other solution is (1.2 , 0)

But basically, you can find other solutions of the equation if you do this:

5x + y = 6

5x = (6 - y)

x = (6 - y) / 5    ; so if you use whatever number of y, you will find the rigth solution for x.

and you can do the opposite too:

5x + y = 6

y = 6 -5x       ; with this, you can use whatever number of x, and find the right y.

I hope this helps you!!!

Chespirito is 22.8 miles from the Finish Line, but runs 3.9 miles per hour. How many hours will it take Chespirito to catch up with Quico? It will take Chespirito hours to catch up with Quico.

Answers

Answer:

4 hrs

Step-by-step explanation:

22.8-17.6=5.2

so they are 5.2 miles apart.

Let they meet after t hrs.

distance coverd by Quico in t hrs=2.6t

distance covere by Chespirito in t hrs =3.9t

3.9t-2.6 t=5.2

or 1.3 t=5.2

t=5.2/1.3 =4
