Answer: The slope of the ant hill is 18/20 or 0.9.

For the slope, we need to put the vertical change over the horizontal change. In this case, the vertical change of the ant hill is 18.

Now for the horizontal change, the entire base is 40. However, we only need half of that because we need the distance from the outside to the middle where the height is. Half of 40 is 20.

Therefore, the slope is up 18 over 20. Or 18/20 = 0.9.

Answer: 18 over 20 or 0.9

Step-by-step explanation: You know that 18 is the height and 40 is the base, so put 18 over 40. Since you only need to know the base from the end to the middle, you need half which is 20. Thus, the answer is 18 over 40.

skelet666 [1.2K]

Answer:

The probability of exactly 2 breakdowns next month = 0.08422

Step-by-step explanation:

To calculate the probability of exactly 2 breakdowns next month, we use Poisson distribution formula.

P(X = x) = (e^-λ)(λˣ)/x!

Mean = λ = 5 breakdowns per month

x = 2 breakdowns per month

P(X = 2) = (e⁻⁵)(5²)/2!

P(X = 2) = 0.08422

The combined area of a square and a rectangle is 225 square yards. the length of the rectangle is 8 times the width of the recta
snow_lady [41]

Answer:

The rectangle:  <u>L = 40 yards.   W = 5 yards</u>

The square: The length and width are both <u>5 yards</u>.

Step-by-step explanation:

<u>Let L and W be the length and width of the rectangle. </u>

<u>Let l and w be the length and width of the square.</u>

Area for each is:

Rectangle:  L*W

Square:       l*w

We are told that <u>L*W + l*w = 225 yards^2</u>

We are also told that

<u>L = 8W </u>

and that

<u>l = W</u>

Since the sides of a square are all equal, w is also W:  <u>w=W</u>

Summarizing and substituting:

L*W + l*w = 225 yards^2

(8W)*W + W*W = 225 yards^2

8W^2 + W^2 = 225 yards^2

9W^2  = 225 yards^2

W^2 = 25

W = 5 feet

---------------------

Therefore, since L = 8W <u>,</u> <u>L = 40 yards.   W = 5 yards</u> for the rectangle.

The square:  l=W, so <u>l = 5 yards, and thus w=5 yards</u>

--------------------------

Check:

Do a rectangle of 40' x 5' plus a square of 5' x 5' have a total combined area of 225 yards^2?

40yd x 5yd + 5yd x 5yd = 225 yards^2?

200 yd^2 + 25 yd^2 = 225 yards^2?

YES

A bag contains A markers, 3/8 of which are red. How many other color markers are in the bag?
vagabundo [1.1K]
8 is the total number of markers in the bag. There are 3 out of 8 that are red. 8-3=5 so there are 5 out of 8 markers that are not red and that are other colors - or 5/8 are other colors.
