Answer:
Step-by-step explanation:
The total number of marbles is 24 + 36 + 60 = 120
Red: 24/120 = 1/5
Blue: 36/120 = 6/20 = 3/10
Yellow: 60 / 120 = 1/2
Answer:
It would be B.
Step-by-step explanation:
4.5 hours = 270 minutes
Answer:
1248 cm^2
Step-by-step explanation:
Volume = Length · Width · Height
Volume = 24 · 6 · 5
Volume = 720 cm^2
Volume = Length · Width · Height
Volume = 8 · 6 · 11
Volume = 528 cm^2
528 + 720 = 1248
Answer: Choice D
It has two factors and the factor (5+y) has two terms
=========================================================
Explanation:
(5+y)*8 is in the form P*Q where
P = 5+y
Q = 8
So we have two factors multiplied together. A factor is simply a number that helps multiply to a larger one. Another example: 14 has the factors 7 and 2 because 7*2 = 14
The factor 5+y has two terms which are 5 and y. The terms are separated by a plus sign. If you had something like 5-y, then you can write it as 5+(-y) and you'd still have two terms.
Answer:
8 gallons of gasoline costs $30.63.
Step-by-step explanation:
Set up a proportion to solve for x, or the cost of 8 gallons of gasoline. The $47.86 goes on top of the first ratio, and 12.5 goes on top of the second. This is because the $47.86 is the cost of the 12.5 gallons of gasoline. Next, put x on the bottom of the first ratio and 8 on the bottom of the second ratio. This is because the amount of money you are trying to find, x, is the cost of the 8 gallons of gasoline. The proportion should look like this: 
To solve the proportion, use cross multiplication. To do that, multiply 8 by 47.86 to get 382.88. Then, divide 382.88 by 12.5. The answer is 30.6304, so round to the nearest cent to get a total of $30.63.
I hope this helps! ☺
