Answer:
880 high-quality version
Step-by-step explanation:
I think the below is your full question:
<em>A Web music store offers two versions of a popular song. The size of the standard version is 2.1megabytes (MB). The size of the high-quality version is 4.5 MB. Yesterday, there were 1290 downloads of the song, for a total download size of 4821 MB. How many downloads of the high-quality version were there?</em>
Here is my answer:
Let x is the number of high-quality version
So the number of standard version= 1290 - x
We also know: total download size of 4821 MB. which means:
4.5x + 2.1(1290-x) = 4821
<=> 4.5x+2709-2.1x=4821
<=> 2.4x=2112
<=> x=880
So there were 880 high-quality version
The total amount of water that Kiesha drinks in 12 days is 20 quarts
The average amount of water she drinks per day is 1 2/3 quarts
The number of days that Keshia drinks at least the average amount of water is 6 days
If she drinks 1 quart of day 13, the average reduces.
<h3>What is the average ?</h3>
The total amount of water drank in the 12 days can be determined by adding the quarts for each day together. When they are added together, the number is 20 quarts.
Average = total amount drank / number of days 1 2/3 quarts
New average = 20 + 1 / 13 = 21 / 13 = 1 7/13 quarts
The average reduces because the quart drank on the 13th day is less than the amount of water drank on the other days.
