Answer:There are 18 students per teacher, and 10 per tutor. there are 8 tutors for 80 students

Step-by-step explanation:

First you need to divide 90 by five to find out how many students per teacher.

For the second question, you should do the same thing. 30 divided by 3.

Last, you should divide 80 by the number from the second question (Ten) to get 8.

50 apples cost $25. How much would 75 apples cost?​
iren [92.7K]

Answer:

$37.50

Step-by-step explanation:

If 50 apples cost $25 to find the cost of 1 apple, we divide the total cost by the total number of items. In this case, we do 25/50.

One apple costs 0.50. If we need 75 apples then we simply multiply 0.50 by 75 which gets us 37.50.

Which strategy best explains how to solve this problem? Apples cost $1.25 per pound. Oranges cost $1.49 per pound. Krystal wants
ValentinkaMS [17]
The best strategy is to use the tables in this example. The tables will give an exact cost for an exact number of apples or oranges. You can then use these pieces of information to determine which number of apples and oranges will get you closest to $10.

The diagram strategy is not accurate based on the information.

The double bar graph is also not going to work because the two pieces of information are related, so you would not create a separate bar for the price and the number of apples.

On a map, 1 inch equals 25 miles.Two cities are 3 inches apart on the map.What is the actual distance between the cities?
SVEN [57.7K]

Answer:

75 miles

Step-by-step explanation:

We are given the scale on the map, which is that 1 inch is 25 miles in real life. We can write that as a ratio of 1 inch: 25 miles. Now say we have two inches, then we have 50 miles because we add on another 25 miles, then we do that again and we get to 75 miles.

Another way to think about it (more complicated):

you can represent ratios as a fraction

so we do 1/25=3/x

To find x, we can do (25*3)/1 which equals 75, if you don't know what I did there then you don't know, sorry!

you can also do it in a different way

same scenario though

you represent it as a fraction

and do 1/25=3/x. We see that the ratio from 1 to 3 is multiplied by 3 so that means the ratio from 25 to x is also going to be multiplied by 3, and 25 multiplied by 3 is 75.

Please let me know if you have any questions.

Michael has a set of 24 math problems to do for homework. Michael completed 1/4 of his homework in 3/4 of an hour. If he continu
gtnhenbr [62]

Given:

Total number of problems = 24

Michael completed \dfrac{1}{4} of his homework in \dfrac{3}{4} of an hour.

To find:

What fraction of his homework would he complete in one hour.

Solution:

We have,

Part of work done in \dfrac{3}{4} of an hour =\dfrac{1}{4}

Part of work done in an hour =\dfrac{4}{3}\times \dfrac{1}{4}

                                                =\dfrac{1}{3}

Therefore, he complete \dfrac{1}{3} of his homework in 1 hour. Hence, all options are incorrect.
