Agent Hunt transferred classified files from the CIA mainframe onto his flash drive. The drive had some files on it before the t

ransfer, and the transfer happened at a rate of 4.4 megabytes per second. After 32 seconds, there were 384 megabytes on the drive. The drive had a maximum capacity of 1000 megabytes. How long from the time that Agent Hunt started the transfer did it take the drive to be completely full? The drive was 243.2MB full when the transfer started.

The hard drive was 24.32% full when the transfer began. 
4.4 x 32 = 140.8
384 - 140.8 = 243.2
243.2 divided by 1000 = 0.2432 
Move the decimal 2 places to the right to create a percentage and you now have your answer of 24.32%

You randomly survey students about year-round school. The results are shown in the graph.
ale4655 [162]

Answer:

27% and 37%

Step-by-step explanation:

Percentage of students who oppose the year-round school = 68%

Percentage of students who support the year-round school = 32%

Margin of error = ± 5%

We have to set up the absolute valued equation to find the range(least and greatest) percentages of students who could be in favor of year-round school.

Since, the percentage of students who support the year-round school is 32% and the margin of error is 5%, this means, the difference between 32% and the least and greatest possible percentages is 5%. It can be either +5% or -5%

This thing can be expressed as absolute valued equation as:

| x - 32 | = 5

Here x represents the least and greatest percentages.

Expanding the equation, we can write:

x - 32 = -5                or                x - 32 = 5

x = -5 + 32                or               x = 5 + 32

x = 27%                                       x= 37%

This means the least percentage of students who be in favor is 27% and the greatest percentage of students is 37%.

Help me pls very much appreciated luvs &lt;33
Ludmilka [50]

Answer:

18

Step-by-step explanation:

Since this is a multiple choice question, I will employ the guess and check method - meaning I will check each answer one by one.

Variable x = dimes = $0.10

Variable y = quarters = $0.25

Set up a system of equations:

x + y = 38

x(0.10) + y(0.25) = 6.80

Plug in each choice into the second equation. You can find the number of quarters that correspond to each number of dimes by using the first equation.

20 dimes:

20 + y = 38

y = 18

20(0.10) + 18(0.25) = 6.80

2 + 4.5 = 6.80

6.5 does not equal 6.80

Because dimes (x) are worth less than quarters (y), this result tells us the answer will be less than 20 dimes as with 20 or more we have less than $6.80. Another example just to show this is true:

38 dimes:

38 + y = 38

y = 0

38(0.10) + 0(0.25) = 6.80

3.8 + 0 = 6.80

3.8 does not equal 6.80.

Since x is worth less than y, we need more of y rather than x. Adding more x will only mean we will get a lower price. Adding more y will mean we get a higher price which is what we need. So only solve for x that is less than 20.

6

6 + y = 38

y = 22

6(0.10) + 32(0.25) = 6.80

0.60 + 8 = 8.60

8.60 does not equal 6.80.

This result is higher than what we wanted (6.80) which means we need more x. Now we only have to solve for x numbers that are greater than 6 and less than 20.

18

18 + y = 38

y = 20

18(0.10) + 20(0.25) = 6.80

1.8 + 5 = 6.8

6.8 does equal 6.8.

Correct!

7.38 is 7.5 % of what ?
nasty-shy [4]
<span>the answer of the question 7.5 % means 7.5/100, so, to find the result we solve the following equation: (7.5 / 100 )X=7.38, this implies X= 738 / 7.5= 98.4, so finally, 7.38 is 7.5% of 98.4. Proof: let’s find the 7.5% of 98.4. That is to compute 98.4 *7.5/100 = 7.38. Hope this helps. Let me know if you need additional help!</span>
