The yearbook club had a meeting. The meeting had 15 people, which is three-fifths of the club. How many people are in the club?

Answers

Answer 1

Answer: 25.
For me, I just did 15 divided by 3, which equals to 5. So.. You do 5 x 5 to find out how many people there are in the club in total.

Answer 2

Answer:

Final answer:

The question is about finding the total number of people in the yearbook club given that 15 people represent three-fifths of the total. By using a proportion, we find that the yearbook club has 25 people.

Explanation:

This is a proportional relationship problem in mathematics. You are given that 15 people represent three-fifths (or 3/5) of the total number of people in the yearbook club. To find the total number of people in the club, you set up the proportion: 15 is to 3 and X is to 5.

Then, cross multiply and solve the equation for X. 3*X = 15*5, therefore X = 75/3 = 25. So, there are 25 people in the yearbook club.

x=-4y
x+5y=2

Answers

Y=2, put -4y in for do to the second equation, and then it's technically 5-4 so then you have 1y=2 then you move the 1 to the other side by dividing 2 by 1.

x = -4y x + 5y = 2
-4y +5y = 2

*add -4y and 5y*
y = 2

x = -4(2)

*Multiply -4 and 2*
x = -8

What is the slope of a line perpendicular to 24x-9y=63

Answers

In order to find the slop it is probably best to put the equation in y=mx+b form. This means to get y by itself on one side.
24x-9y=63 will then become -9y=63-24x in which y has been isolated.
Then you should divided by -9 to get the final form: y=24x/9 -63/9.
Now you can get the slope of the perpendicular line by taking the slope of the original equation and finding its reciprocal which is -9/24x. This is your answer.

There are 30 homes in Neighborhood A. Each year, the number of homes increases by 20%. Just down the road, Neighborhood B has 45 homes. Each year, 3 new homes are built in Neighborhood B.Part A: Write functions to represent the number of homes in Neighborhood A and Neighborhood B throughout the years. (4 points)
Part B: How many homes does Neighborhood A have after 5 years? How many does Neighborhood B have after the same number of years? (2 points)
Part C: After approximately how many years is the number of homes in Neighborhood A and Neighborhood B the same? Justify your answer mathematically. (4 points)

Answers

Neighborhood A: 30 homes and increases by 20% per year
Neighborhood B: 45 homes and increases by 3 per year.

N.A = 30 (1.20)^t
N.B = 45 + 3(t)

t = 5

N.A = 30(1.20)^5 = 30(2.48832) = 74.65 or 75
N.B = 45 + 3(5) = 45 + 15 = 60

V=A*h*1/3 - equation to count volume of the pyramid
A=93.5 sq ft
h=6 ft
V=93.5*6*1/3=93.5*2=187 cubic ft

The volume of a pyramid with a hexagon base is: 1/3 * area of the base * height.

So: 1/3 * 93.5 * 6 = 187.
