Answer:
1) x=5
2) x=7
3) x=8
4) x=4
5) x=7
6) x=8
Step-by-step explanation:
Since each pair is similar, their sides are in ratio:
1)
(2x+2)/6=18/9
2x+2=2*6
2x=12-2
x=10/2
x=5
2)
(x-2)/4=10/8
x-2=1.25*4
x=5+2
x=7
3)
(3x-6)/12=24/16
3x-6=1.5*12
3x=18+6
x=24/3
x=8
4)
(2x+4)/15=16/20
2x+4=0.8*15
2x=12-4
x=8/2
x=4
5)
(x+2)/15=6/10
x+2=0.6*15
x=9-2
x=7
6)
(-3+x)/6=10/12
-3+x=6*(10/12)
x=5+3
x=8

2 boys 2 girls, 1 boy 3 girls, 4 girls
Step-by-step explanation:
I think this is what u asked I'm not sure thi
b) By capacity, the problem asks the volume. So let's find the volume of that small cylinder
So by plugging into the formula the given data we can tell that the capacity of that cylinder is indeed 808.5cm³
c) Note that now, the point is to find the Volume of that cuboid (rectangular prism), which we can find by doing the following formula:
d) And finally, the density is given by the following ratio:
