A group of 12 people want to go to a concert. They can travel in a small car that takes one driver and one passenger and two car
trapecia [35]

Answer: There are 60 ways that they can travel to the concert.

Step-by-step explanation:

Since we have given that

Number of people want to go to a concert = 12

Number of cars = 3

Number of drivers in the group = 5

So, using the "Fundamental theorem of counting":

We get that

5\times 4\times 3\\\\=60

Hence, there are 60 ways that they can travel to the concert.

Find angle E if angle E and angle F are supplementary, angle E= 2x + 5 and angle F= 5x - 38
Bingel [31]

Answer:

About 65.86 degrees

Step-by-step explanation:

A supplementary angle means that the angles add to 180 degrees.

Angle E + Angle F = 180 degrees.

You can then plug in the given equations for E and F.

2x + 5   +   5x - 38   = 180

Combine like terms:

2x + 5x = 7x

5 - 38 = -33

New equation: 7x-33=180

Remove the -33 from the left side of the equation by adding 33 to each side

7x-33+33 = 180+33   --->   7x = 213

Divide by 7 on each side

7x/7 = 213/7  --->   x = about 30.43

You can then plug this into your equation for E and solve

2(30.43) + 5 = 65.86 Degrees

What is the equation of the time that passes through the poin3,2 ani<br> has an undefined slope?
sesenic [268]

Answer:

x=3

Step-by-step explanation:

An undefined slope means it is a vertical line, and every possible point at that line is at x = 3. y does not depend on x, and x cannot be anything other than 3, so the equation is just x=3
