Kaylee surveyed 920 of the students in her school about their favorite color. 95% said

their favorite color was blue. How many students' favorite color was blue?

Answers

Answer:

x = 874

Step-by-step explanation

Set up your equation like this: Part/whole = percent/100

Assign the variable x to the unknown part of the equation and add in the known numbers:

So in this situation it would be: x/920 = 95/100

Solve for x:

100 times X = 920 times 95. (cross multiply)

That leaves you with 100x = 87,400

Divide both sides by 100:

x = 874

A dozen donuts cost $2.99. To the nearest cent, what is the cost of 1 donut?

Answers

Answer:

that person is correct, each donut is only .25 cents because every 4 donuts are $1, multiply 4 by 3 and you get 12, 12=dozen. Since the total price is $3 it makes sense that each donut in .25 cents and every 4 donuts $1

HOPE THIS HELPS AND HOPE THIS MAKES SENSE!!!!!!!

If a dozen donuts cost $2.99 then the cost of one donut is approximately $0.25.

What is Division?

A division is a process of splitting a specific amount into equal parts.

Given that a dozen donuts cost $2.99.

We have to find the cost of 1 donut

As there are 12 donuts in a dozen, so to find the cost of one donut.

1 dozen donuts = 12 donuts.

One dozen donuts equal to twelve donuts.

To find the cost of 1 donut we need to divide the cost of a dozen by 12, because we are splitting the cost two point nine nine among twelve donuts.

$2.99 ÷ 12

Two point nine nine is divided with twelve we get zero point two five.

= $0.25

Therefore, the cost of one donut is approximately $0.25 to the nearest cent.

What is the perimeter of JKL?

Answers

Answer:

The perimeter of JKL is 60 units.

Step-by-step explanation:

The two tangents of a circle formed by a vertex outside the circle will always be the same distance, this means that JA = JB = 13, LA = LC = 7, and KB = KC = 10. JL = JA + LA = 20, KL = LC + KC = 17, and JK = JB + KB = 23. So the perimeter of triangle JKL is 20 + 17 + 23 = 60 units.
