There are 1200 students at a school and 390 of them are boys if each classroom holds 30 students how many classrooms are needed

vodomira [7]

Answer:

40 classrooms

Step-by-step explanation:

Divide 1200 by 30.

1200÷30=40

If 390 students are boys just subtract 390 from 1200.

1200-390= 810

There must be 810 girls if there are 390 boys

I need help on this please

Leya [2.2K]

The expression we have is:

$2xy\cdot xy^2$

And we are given some values for x and y:

$\begin{gathered} x=2 \\ y=4 \end{gathered}$

The first step will be to substitute the given values into the expression:

$2(2)(4)\cdot(2)(4)^2$

The next step is to solve 4^2 which is equal to 16:

$2(2)(4)\cdot(2)(16)$

And then we solve the multiplications, 2(2)(4) is equal to 16 and (2)(16) is equal to 32:

$16\cdot32$

Solving this final multiplication we get the result:

$512$

Answer: 512

Assuming you mean 30 miles per hour, then the answer should be 160 miles apart.
