Answer: 2 1/4 hours
Step-by-step explanation:
If Rafael practices 3/4 of an hour each day for three days he will have had 3/4 of an hour practice after day 1, 1 1/2 hours of practice after day 2 and then 2 1/4 hours of practice after day 3.
3 x 3/4 = 9/4
9/4= 2 1/4
Hi there! The answer is 80 green apples.
In a bag of apples, the ratio of red apples to green apples is 3:4, so we must first realise that there is a total of 7 parts.
3 of these parts constist if red apples. In other terms 3 / 7 equals 60. Now divide by 3 to find 1 / 7. Hence, 1 / 7 equals 60 / 3 = 20 apples.
4 of the total 7 parts consist of green apples, so we must multiply the preceding outcome by 4 to find our answer. 4 / 7 equals 20 × 4 = 80 apples.
Therefore, there are 80 green apples in the bag.

<u>Average Value</u>
The mean or average of a sample is a number that represents the whole set by the center value of them. The formula to compute the average is
Where xi is the value of the element i and n is the number of elements in the set
We need to find an estimate of how many grapefruits Lily purchased knowing the heaviest and the lightest weight of the set. We can find the average value by using the two extreme values:
If each grapefruit weighed 1.5 pounds, then we can estimate the 22.17 pounds of them will contain
Multiples of 6 between 50 and 100 are 54, 60, 66, 72, 78, 84, 90, and 96.
