Carla and four of her friends went to the movie theater and found that there were only five seats left in the theater. How many different ways can Carla and her friends sit in these five seats?



A. 24
B. 120
C. 256
D. 396

Answers

Answer:

24

Step-by-step explanation:

Answer:B

Step-by-step explanation:

The number of different ways Carla and her friends can sit in the five seats can be calculated using the concept of permutations. Since there are 5 seats available and 5 people, each person can occupy one seat.

The number of ways to arrange the 5 people in the 5 seats can be calculated as 5 factorial (5!). The factorial of a number is the product of all positive integers less than or equal to that number.

5! = 5 * 4 * 3 * 2 * 1 = 120

Therefore, the correct answer is B. 120.

A very exclusive college except approximately 2 students out of 5 applicants. If there were 250 total applicants, how many students were not accepted?

Answers

Answer:

150 students were not accepted.

Step-by-step explanation:

The ratio right now is 2 to 5 you would need to find an equal ratio with 250 as the second number. 5 is a factor of 250 because if you do 5 x 50 you get 250. So you would multiply 2 by 50 as well which is 100. The ratio is 100 to 250 with 100 being the students being accepted and 250 being the total number of people that applied. Though the question is asking for those that did not pass. If 100 people passed then everyone else out of 250 didn't and 250 - 100 is 150.

The answer is C, 25% increase. To find the increase, subtract starting value (780) from the final value (975). It equals out to be 195. Divide 195 by the starting value which turns out to be 0.25. Then, multiply 0.25 by 100 which equals out to be 25.

What is the median of these numbers :
90, 95, 92, 93, 91, 97

Answers

Answer:92.5

Step-by-step explanation:

The middle numbers are 92 and 93 and then you add 92+93=185 and 185/2=92.5

The median is 92.5

Work :

1) Place the numbers in order
90, 91, 92, 93, 95, 97

2) There are two medians (92 & 93)

3) Add both numbers then divide by 2, because it’s two numbers and you need 1 median

92+93 = 185/2 = 92.5

What is the scale factor of the dilation?

Is the dilation an enlargement or a reduction?

Answers

Answers:

Scale Factor = 3/4

This is a reduction

======================================================

Explanation:

Let's focus on the point R(4,4). That's the preimage point for the image of R ' (3,3).

Let k be the scale factor. We multiply this value of k by the x,y coordinates of point R to jump to R '

we have x = 4 jump to 4k which is the x coordinate of point R'

So we set 4k equal to 3 and solve for k to get k = 3/4. The scale factor is 3/4 or 0.75

We have a reduction since the image triangle T'R'S' is smaller compared to the preimage triangle TRS. We can see that we have a reduction by looking at the scale factor. If 0 < k < 1, then we have a reduction. If k > 1, then we have an enlargement instead. So we go with the first option since 0 < 3/4 < 1 or you could say 0 < 0.75 < 1.

Answer:

A reduction (think shrinking) is a dilation that creates a smaller image, and an enlargement is a dilation that creates a larger image

What is the value of x?

Answers

Answer:

28!

Step-by-step explanation:

soooooo its a 90 degree angle

2x+1+33=90

2x+34=90

    -34  

2x=56

x=28

Answer:

x = 28°

Step-by-step explanation:

As you see that the angle is an right angle where right angles = 90°

So,

(2x + 1) + 33 = 90°

Subtract 33 on both sides:

2x + 1 = 57

Subtract 1 on both sides:

2x = 56

Divide 2 on both sides:

x = 28°

the sides of a rectangle are in the ratio 2:5. if the longer side of the rectangle is 25.5 in., what are it's width, perimeter, and area ?

Answers

Answer: The width of the rectangle is 10.2 inches, the perimeter is 71.4 inches,  the area is 260.1 inches.

Step-by-step explanation:

25.5/5=5.1

The width is 10.2 inches

25.5*2+10.2*2=71.4

The perimeter is 71.4 inches

20.5*10.2=260.1

The area is 260.1

Width=10.2 in. Perimeter=71.4 in. Area=and 260.1 in.
