Answer:
4.5 hours
Step-by-step explanation:
let t be the time elapsed
Therefore, we can set up a system of equations and solve accordingly
2t + 16.5 = 4t + 7.5
2t = 9
t = 4.5 hours more till they paint the same amount in square feet
3/4 x 7 =5 and 1/4 cup
1/4 x 7 = 1 and 3/4 cup
1/4 + 3/4 =1 cup
so 7 cups in total hope this helped:)! brainliest please:)?
Answer:
10 feet
Step-by-step explanation:
pythagorean theorem
If you roll two dice, there are 6•6 possible outcomes (36 outcomes). That’s your denominator.
To roll a 9, you’d need
Die 1: 3, Die 2: 6
Die 1: 4, Die 2: 5
Die 1: 5, Die 2: 4
Die 1: 6, Die 2: 3
There are 4 ways to roll a nine, so that’s your numerator.
4/36 or 1/9 is your probability.
Answer:
x=24
Step-by-step explanation:
