The Number of text messages sent in a month is 1.68 × 
Step-by-step explanation:
Step 1 :
Total number of teenagers in United States = 21 million
Average text messages sent per month = 800
We need to find the number of text messages sent each month
Step 2 :
The number of text messages in a month can be computed by taking the product of the total number of teenagers and average messages sent per month
Therefore
Number of text messages that is sent in a month = 21 million × 800
= 21 × 
× 800
= 168 × = 1.68 ×
Step 3 :
Answer :
The Number of text messages that is sent in a month is 1.68 ×
Answer:
C
Step-by-step explanation:
Notice that there is a little triangle formed by the lines on the right side of the diagram.
Let's find the angle measures of the triangle. One of them has a supplementary angle of 96 degrees, which means that the actual interior angle is 180 - 96 = 84 degrees.
Another angle has a supplementary angle of 137, which means that the actual interior angle of the triangle is 180 - 137 = 43 degrees.
Finally, we have the expression 2x - 23, which is an exterior angle. By definition, this exterior angle is equal to the sum of the interior angles of the triangle that do not include its supplementary angle. In other words:
2x - 23 = 84 + 43
Now we just solve for x:
2x - 23 = 84 + 43 = 127
2x = 127 + 23 = 150
x = 150/2 = 75 degrees
The answer is 75 degrees, or C.

Answer:
If line EF was dilated by a scale of 1/2 from the origin to get line E'F', then if line E'F' is dilated by a scale of 2 from the origin, EF is obtained. Also, the length of EF is double than the length of E'F'.
Dilation by a scale of 2 from the origin transforms point (x,y) into (2*x, 2*y)
E'(1,0) -> E(2,0)
F'(1, 3) ->F(2, 6)
length of E'F': 3
length of EF: 6
