3x + 4x + 5x = 12x
=\ \textgreater \  12x = 90
x = 90/12 = 15/2
3x = 3*(15/2) = 45/2 = 22.5 cm
4x = 4*(15/2) = 30 cm
5x = 5*(15/2) = 75/2 = 37.5 cm

a store received 500 containers of milk to be sold by Febuary 1. Each container the store sold $0.83 and sold for $1.67. The sto

$409.80.

The amount of net profit the store makes on each container is given by 1.67-0.83 (the amount it is sold for subtracted by the amount it costs the store), which is $0.84 per container.  They sell 470 containers, so the net profit at this point is 470(0.84) = $394.80.

However, since the distributor is giving the store a $0.50 refund on all every container under 500 that the store sells, the store gets additional money back:

500-470 = 30 containers not sold
30(0.50) = 15

So the total profit is $394.80 + 15 = $409.80.

The ratio of girls to boys in Mr. Smith's homeroom is 3:4. The ratio in Mr. Smith's homeroom to students in the whole 7th grade
Leno4ka [110]

3:4 = G:B

1:5 = Mr. Smith's class: 7th Grade

2:7= 7th: Middle school

12 girls = 3 units

1 unit = 12/3= 4

Boys = 4x4= 16

<em>Whole class = 28 students</em>

Class : Grade = 1:5     <em> 7 = number of units in  Mr. Smith's class</em>

28 = 1 unit

5 units= 28x5= 140 <em>There are 140 kids in the grade</em>

140 = 2 units

1 unit = 140/2= 70

70x7=490

<u><em>There are 490 students in the whole grade</em></u>
