The rule is times 3.
2*3=6
6*3=18
and so on
Answer:
Word problem: A recipe for making cookies use half cup of sugar for 1 cup of flour to make one pound of cookies. How many cups of sugar you need to make 3 pound of cookies.
As you can see to solve that problem you need to multiply the fraction 1/2, which is the number of cups needed to make 1 pound of cookies, times the number of pounds that you want to make.
So, for this problem you have to multiply 1/2 times 3.
My estimate is that the result is 1.5.
You can verify my estimate by multiplying:
1 3x1 3
3 x ----- = ------ = ------ = 1.5
2. 1x2 2
So, I have shown that my estimate was correct.
You just have to try them all:
Y=x+3 ≈ 6=3+3 ≈ 6=6 √
Y=x+3 ≈ 8=4+3 ≈ 8=7 X
So the first function doesn't work
Y=2x ≈ 6=2(3) ≈ 6=6 √
Y=2x ≈ 8=2(4) ≈ 8=8 √
Second function works
Y=x+4 ≈ 6=3+4 ≈ 6=7 X
Third function does not work
Y=12-x ≈ 6=12-3 ≈ 6=9 X
Fourth function doesn't work
So your answer is Y=2X :)
The answer is 60%
60% of 100 is 60
60% of 200 is 120
Answer:
63m³
Step-by-step explanation:
volume of a cylinder = πr²h
r = 2m, h = 5m
= 22/7 × 2² × 5
= 62.86m³
approx 63m³
