Answer 1

Answer:

95%

Step-by-step explanation:

So, we can see on the chart that 78 out of 82 people from ages 18 to 22 use Face.book. So we're trying to find what percentage 78 is of 82:

The first step is to write 78 as a fraction of 82, which is:

78/82

In order to find the simplest form of 78/82 we cancel out the greatest common divisor of 78 and 82, which is 2 :

78/82 = 37/41  

Now we just need to convert this fraction to a percentage :

 37/41 = 95% (rounded)

So we have the final answer :

78 is 95% of 82

Which means that:

Approximately 95% of people from ages 18 to 22 use Face.book

hope this helps:)

Answer:

okay I'm not 100% sure but I have a good idea (it's okay if u remove me it's just an educated guess)

89%

Step-by-step explanation:

if there were 100 students that would mean 1 student represented 1% of the results. so if there were 50 students 1 student would represent 2% of the results. so if two students were removed then that would mean the result would improve by a total of 4% which would get you 89%

Answer:

1: Tip, $2.23

2: Tax, $0.74

3: Total, $17.87

4: Split, $5.95

Step-by-step explanation:

To find the tip, you must multiply the tip percentage by the bill, (which has not been taxed yet). The tip is 15%, which is equivalent to 0.15. The tip multiplied by the bill (0.15×14.90) equals $2.23.

To find the tax, you do the same as you did with the tip. The tax is 5%, which equals 0.05. The tax multiplied by the bill, (0.05×14.90) equals $0.74. The total cost is the bill, tip, and tax added together, (14.90+2.23+0.74) equals $17.87. To find out how much each person will pay equally, you must divide the total bill by the amount of people, (17.87÷3) which equals $5.95.

Isolate y for 6+3y=0: y = -2

For x= 3 + y: x = 1

Answer:

x = 15, Angles are both 130!

Step-by-step explanation:

Since this is an example of Alternate Exterior Angles, you could set these equal to eachother!

9x-5 = 7x + 25

-7x         -7x

Subtract 7x from both sides.

2x - 5 = 25

       +5   +5

Add 5 to both sides.

2x = 30

Divide by two to get x by itself .

x  = 15, now you can plug this in for X and get the angle

9(15) - 5 = 130

Answer:

Since this is an example of Alternate Exterior Angles, you could set these equal to each other! its 125

Step-by-step explanation:

9x-5 = 7x + 25

-7x -7x

Subtract 7x from both sides.

2x - 5 = 25

+5 +5

Add 5 to both sides.

2x = 30

Divide by two to get x by itself .

x = 15, now you can plug this in for X and get the angle

9(15) - 10 = 125
