Each day she eats 1/2 cups of rice. But we want to know how long it will take to each 2 cups worth. so lets make an equation.
.5x = 2
Divide both sides by .5
x = 4
So it will take 4 days to eat 2 cups of rice cereal.
Answer:
The longer leg is opposite the 60, so to get the shorter leg you have to divide by \sqrt{3}
18 / \sqrt{3} = 6 \sqrt{3}
Answer:
I think it's D. The independent variable is the length of the race. The dependent variable is the time.
Step-by-step explanation:
Here I'm quoting user kaylaj051903 "because an independent variable is something that is constant and does not change throughout the problem. The dependent variable depends on the independent variable. The race is a 5K race. That will not change. What will change is how long it takes Stephanie to run the 5K race."
It would be a RECTANGLE proportional to the base of the pyramid.
Answer: 1st train = 364 mph, 2nd train = 356.2
Step-by-step explanation:
Train 1: x + 7.8
Train 2: x
Train 1 + Train 2 = Sum
x + 7.8 + x = 720.2
7.8 + 2x = 720.2
2x = 712.4
x = 356.2
Train 1: x + 7.8
= 356.2 + 7.8
= 364
