The number of boys varies directly as the number of girls and inversely as the number of teachers. When there are 24 boys and 16

girls, there are 2 teachers. How many girls are there when there are 72 boys and 1 teacher?

SO from what I did was...

Since 24 x 3 = 72 , I did the same to 16. 

16 x 3 = 48 

But because instead of their being 3 teachers there is 1... What I did is just was to divide 48 / 2 which gave me the answer of 24... 

So what I think the answer is... 

There are 72 boys, 24 girls, and 1 teacher... 

Unless I am just dumb and it would be 48 girls, but I think I did it right. 

I hope I was able to help out.

Answer:

They are both proportional.

Tank A = .00375 minutes/gallon

Tank B = 2/600 or ~0.003 minutes/gallon

Step-by-step explanation:

They are both proportional because as time increases, the amount of gallons increases.

Tank A unit rate

Tank B unit rate

Rate = rise / run

Choose points on the graph that has definite points.

Tank A = (1.5 mins - 0.75 mins) / 200 gallons

Tank A = .00375 minutes/gallon

Tank B = (2 mins - 0 mins) / 600 gallons

Tank B = 2/600 or .003 minutes/gallon

I dd the assignment and I didn't get the right answer, the correct answer was 3/4
gtnhenbr [62]

Answer:

Step-by-step explanation:

The 2 figures are similar so corresponding sides are in the same ratio.

The factor is the value that you have to multiply a side in the first rectangle to get the corresponding side in the second rectangle.

12 ----> 9  

So:

12 * f = 9     where f is the factor

f = 9/12 = 3/4.
