pychu [463]

Answer: There are 90 different schedules are possible for Molly Kay.

Step-by-step explanation:

Since we have given that

Three time scheduled at 8:00, 10:00, 11:00.

Number of courses offer at 8:00 = 5

Number of courses offer at 10:00 = 9

Number of courses offer at 11:00 = 2

So, the number of different schedules are possible for Molly Kay is given by

^{5}C_1\times ^9C_1\times ^2C_1\\\\=5\times 9\times 2\\\\=45\times 2\\\\=90

Hence, there are 90 different schedules are possible for Molly Kay.

Softa [21]

Answer:

22 per dog when she is walking 8

she would make 176 for walking all 8 of them

Step-by-step explanation:

For each additional dog she walks she is giving a discount. If you subtract each one you will see she is giving a 2.75 discount.

40-37.25 = 2.75

37.25-34.50 = 2.75

34.50-31.75 = 2.75

Since you know she gives a discount of 2.75 per dog you can take that times the number of dogs (8).

8 x 2.75 = 22 per dog

Then take that amount and multiply it by the number of dogs she is walking.

8 x 22 = 176 for all 8 dogs

Find the approximate side length of a square game board with an area of 171 in?
Makovka662 [10]

<em>Greetings from Brasil...</em>

According to the statement of the question, we conclude that the area of a square is requested, whose value is 171 in²

The area of a square is given by the expression:

A = S²

<em>where S is the side of the square - just what we want to know</em>

So:

A = S²

171 = S²

√171 = S

<h3>S ≈ 13.08in</h3>
