There are 96 female staff in an office. If the ratio of male staff to female staff is 3:4, find the number of male staff​.
Alex

Answer:60 male staff

Step-by-step explanation:

Ok, there are 96 female staff. The ratio of male to female is 3:4. We’re going to use a proportion which looks like this. 3/4 = x/96. X is a variable that takes the place of the male staff since we don’t know what it is. Now, the question is what do we do to get from 4 to 96. So 96/4 = 24, so 4 x 20 = 96. To keep this ratio equivalent whatever you do to the top you have to do to the bottom so 4 x 20 = 96 and 3 x 20 = 60. So there are 60 male staff.

ickets to the high school reunion cost $35 with a meal and $25 without a meal. The reunion committee sells 70 tickets for $2,250
Crank

Answer:

50 tickets with a meal and 20 tickets without a meal

Step-by-step explanation:

Create two equations. Group the information based on labels. All the amounts that have $ in it go with one equation and the number of tickets will be in the second equation.

I will let x represent with a meal and y will represent without a meal

35x + 25y = 2250

x + y = 70

I will solve using substitution, so I will solve for y in the second equation. To do this, I will subtract x from both sides.

x - x + y = 70 - x

y = 70 - x

Now I will substitute in for y in the first equation and solve for x.

35x + 25(70 - x) = 2250

35x + 1750 - 25x = 2250

10x + 1750 = 2250

10x + 1750 - 1750 = 2250 - 1750

10x = 500

10x/10 = 500/10

x = 50

Now I will solve for y. I will use the original second equation and substitute 50 in for x.

x + y = 70

50 + y = 70

50 - 50 + y = 70 -50

y = 20

50 tickets with a meal and 20 tickets without a meal

Find the average rate of change of a function that contains the points (-2,3) and (2,5). -2, -1/2, 1/2, 2
UkoKoshka [18]

Answer:

The answer is "\frac{1}{2}".

Step-by-step explanation:

Given points:

(-2,3)\\\\(2,5)\\\\

average rate=?

x_1=-2\\\\y_1=3\\\\x_2=2\\\\y_2=5

average\ rate=\frac{y_2-y_1}{x_2-x_1}

                     =\frac{5-3}{2-(-2)}\\\\=\frac{5-3}{2+2}\\\\=\frac{2}{4}\\\\=\frac{1}{2}
