I did most of it for you-
Volume of the cone is 13.1
Volume of the cylinder is 18.9
Now, you just subtract two of the flat circular surfaces, because the two shapes are attached, therefore those parts are not surface area. And there is your answer.
Answer:
30
Step-by-step explanation:
2/3 = x/18
2*18 = 3x
36 = 3x
x=12
so there are 12 boys
12+18=30
Plug in 0 into x of the equation y=2x+3, solve it, then take that answer and use that as your y then plug in the answer for y and solve for x. (i realized i am very bad at explaining this over this. Sorry I tried)
Thousand=2,000
ten thousand=7,000
hundred thousand=100,072,055(i think :/ )
million(not sure) 10million?
Answer:
Yes
Step-by-step explanation:
Multiply one eqution so that they are same.
For example:
2x+17y+48=0
x+8y-6=0 --> multiply 2 times, so 2x+16y-12=0
and now you can use it as if they are coefficients for both variables
