MachineA: y=120x
MachineA could pack in 12 min
y=120(12)
y=1440
MachineB could pack in 12 min
y=150(12)
y=1800
MachineB pack than MachineA
1800-1440
=360 candies
Answer: 45 miles
Step-by-step explanation:
1 inch = 15 miles. Because there are 3 inches we will need to multiply by 3. 3 x 15= 45
I was too just a couple of weeks ago. So direct variation is the constant way to variables change together. EX:
x y
1 2
2 4
3 6
Direct variation must be in the format b=ka where k is a constant. So the direct variation here could be y=2x. Understand?
Well, a way to do this problem would be to find the set of numbers that all of rational square roots. A list of perfect squares would be 1^2=1, 2^2=4, 3^2=9, 4^2=16, 5^2=25, 6^2=36, 7^2=49, 8^2=64, 9^2=81, 10^2=100.
