Incomplete question. I Assumed the number of people is 6. In other words, In how many ways can 6 people be lined up to get on a bus if a particular person always boards the bus first or last?

Answer:

<u>6</u>

Step-by-step explanation:

Note, this question involves the use of the permutation formula; which helps <u>determine the arrangement or rearrangement of a set of objects in an ordered way.</u> Since we are told a particular person (ie 1 person) from among the group always boards first or last, it forms our r.

P(n,r)= \frac{n!}{(n-r)!} where n = number of people; r = the difference taken at a time.

P(n,r) = \frac{6!}{(6-1)!} = \frac{720}{120} = 6

Write a real world problem that you would represent with the equation 4x+5=37.
AURORKA [14]
Bob was 5 feet off the ground. He travels 4 feet every single second. How long will it take for him to reach 37 feet?

4x + 5 = 37

4x + 5 (-5) = 37 (-5)

4x = 32

4x/4 = 32/4

x = 8

It will take Bob ~8 seconds to reach 37 feet*

A triangle has sides with lengths of 48 meters, 51 meters, and 31 meters. Is it a right triangle?
Genrish500 [490]

Answer:

Step-by-step explanation:

Formula = a^2 + b^2 = c^2

Putting values

= (31)^2 + (48)^2 = (51)^2

= 961 + 2304 = 2601

= 3265 = 2601

Both sides are not equal so it is not a right triangle
