Total number of parts:
2+3=5.

Each part is:
20 cookies/ 5 parts= 4 cookies/part.

Number of chocolate cookies is:
4 cookies/part* 2 parts= 8 cookies.

Number of sugar cookies is:
4 cookies/part* 3 parts= 12 cookies.

There are 8 chocolate cookies and 12 sugar cookies~

Answer:

10 miles

Step-by-step explanation:

Let m represent the number of miles Kayla runs. We want to find m such that ...

0.50m = 5.00

Divide by the coefficient of m:

m = 5.00/0.50 = 10

Kayla has to run 10 miles to get the same donation from both parents.

The area of a bulletin board is 55 ft2. The length is nine feet less than four times the width. Find the length and the width, i

galben [10]

Answer:

The length and width are 11ft and 5ft respectively

Step-by-step explanation:

let the

length = L

Width = W

Area = LW = 55

The length is nine feet less than four times the width

L = 4W - 9

W (4W - 9) = 55

4W^2 - 9W -55 = 0

4W^2 - 20W + 11W - 55 = 0

4W(W - 5) + 11(W - 5) = 0

(W - 5)(4W + 11) = 0

W - 5 = 0 , 4W + 11=0

W = 5 or - 11/4

since the width cannot be negative, W = 5

LW = 55

L = 55/5

L = 11

The length and width are 11ft and 5ft respectively.

Suzanne is making a circular table out of a square piece of wood. The radius of the circle that she is cutting is 3 feet. How

Viefleur [7K]

Answer:

The waste Suzanne is going to have is around 7.726.

8 if looking for nearest square foot.

Step-by-step explanation:

Area for a square - x*x (length times length)

Area for a circle - r^2*pi

Find the area of the circle first, which plug in r as 3.

3^2*pi

9pi

≈28.27433

Notice for a circle inside a square, the length of the square is the diameter of the circle.

By knowing 2r=diameter, we know the length of the square is 6

substitute x as 6.

6*6=36

Find the waste= Area of square - Area of circle

36-28.27433

≈7.726

The image I attached should give you a clue on how the problem is being done and help you to understand what the 3 feet means.
