There are 1200 students at a school.

const2013 [10]

Answer:

The number of boys that have school dinners is 381.

Step-by-step explanation:

First, we need to find how many students have school dinners:

$SD = 1200*0.62 = 744$

The percent of girls that have school dinners:

$\%SD_{g} = 100\% - 45\% = 55\%$

Now, we need to find the number of boys (b) and girls (g) at a school:

$g = 1200*0.55 = 660$

$b=1200 - 660 = 540$

Hence. the percent of boys that have school dinners is given by:

$SD = g*\%SD_{g} + b*\%SD_{b}$

$\%SD_{b} = \frac{SD - g*\%SD_{g}}{b} = \frac{744 - 660*0.55}{540} = 0.706$

$\%SD_{b} = 70.6\%$

Finally, the number of boys that have school dinners is:

$B = 540*0.706 = 381$

Therefore, the number of boys that have school dinners is 381.

What is the surface area of the box 12in 4in 3in

Slav-nsk [51]

Find the area of the base:
(4)(3) = 12sqft
Find the area of the sides:
(4)(12) = 48sqft
There are 2 bases and 4 sides, therefore:
12(2) + 48(4) = 24 + 192 = 216sqft
