Answer:
0.008
Step-by-step explanation:
To know the steps pls look at the pic above
40 boys and 68 girls
let's start with variables and an equation.
boys: x
girls: 2x - 12
and we know that boys and girls make up the class. so let's add the two expressions.
x + 2x - 12 = 108
3x - 12 = 108
+ 12 + 12
3x = 120
x = 40 boys
BUT x is only the number of BOYS in the class. so we have to find girls now. let's plug in our value of x into the girls' equation.
2x - 12 = # of girls
2(40) -12 = # of girls
80 - 12 = # of girls
68 girls
let's check our answer!
68 + 40 does in fact add to 108, therefore our answer is correct.
Do each prism seperately
(8x10x5)+(4x4x5)
(400)+(80)
480in^3
The answer would be 2 > 0.
37 and 1 / 4 = 37 * 6 = 74 * 3 = 222
