Find out how much one bag costs
divide $8.16 by 6 to get $1.36
multiply $1.36 by 8 to give you $10.88
S= 2 (LW) +2 (LH) +2(WH)
then we can plug in the values we know! :)
S= 2(2*3) +2(2*4) +2(3*4)
Then we can do some simplifying
S= 2(6) +2(8) +2(12)
Then some more multiplying...
S=12 +16 +24
Then lastly, addition
S= 52 cm^2
sorry this one but im sure someone can help you
Hello!
To solve this you have to find the ratio between the two cylinders
Cylinder 1 height is 30
Cylinder 2 height is 20
this is a 30:20 ratio
This can be reduced to a 3:2 ratio
Now you look for one that are also equal to 3:2
3 * 7 = 21
2 * 7 = 14
The answers are 3:2 and 21:14
Hope this helps!
