OK, so to solve this, we can use proportions.
You would set up 3/8 gallons over 1/4 an hour to x over 1 hour. But to make this easier let's do decimals.
0.375 x
--------- = --------
0.25 1
Now just cross multiply.0.375=0.25xAnd divide to get rid of the x1.5=x
So, it would leak 1.5 gallons of water in one hour! I hope you were able to understand this. Please ask any questions. ;)
Answer:
.15 or 15%
Step-by-step explanation:
There are a total of 4 + 10 + 7 + 5 = 26 marbles in the bucket.
There are a total of 4 red marbles.
The chance of you getting a red marble is 4/26, or 2/13.
2 divided by 13 is .15, and .15 times 100 = 15%.
Answer: third option.
Step-by-step explanation:
You need to use the formula for calculate the distance between two points:
Given the points (0,9) (-8,-4), you can subsitutute each coordinate into the formula to calculate the distance between them.
Then, you get that the distance between these points is:
This matches with the third option.
Answer:
the first one is 7.59 and your second answer is -11.4
