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.

What is the area of Vivian’s garage door?
sergey [27]

The area  of Vivian’s garage door is 62.5 square feet

<h3>Area of composite shape.</h3>

The Vivian garage is made up of a trapezoid and a rectangle. The area of the door is expressed as;

Area = Area of rectangle + area of trapezoid

Area = (5 * 8) + 0.5(7 + 8)*3
Area= 40 +22.5
Area = 62.5 square feet

Hence the area  of Vivian’s garage door is 62.5 square feet

A car is traveling at a speed of 55 mph. You want to write an algebraic expression to show how far the car will travel in a cert
WARRIOR [948]

distance = rate * time.

distance is number of miles the car has traveled.

rate = number of miles per hour the car is traveling at.

time = number of hours the car has been driven.

let D = distance.

let T = time.

let R = rate


the general equation is D = R*T

as long as the car will always be driven at 55 miles per hour, you can substitute 55 for R and that becomes your constant.

The equation then becomes D = 55 * T.

example:

you drive 5 hours.

D = 55 * T = 55 * 5 = 275 miles.

If you drive at 55 miles per hour for 5 hours, you will have driven 275 miles.

Hope this helps!
