In a recent year there were about 400,000,000 mobile internet users. That same year, there were about 1.2 x 10^9 desktop interne

Naddika [18.5K]

Answer:

The number of desktop internet users are 3 times more than the number of mobile internet users.

Step-by-step explanation:

We are given the following in the question:

Number of mobile internet users = 400,000,000

$400,000,000 = 4\times 10^{8}$

Number of desktop internet user =

$1.2 \times 10^9$

Comparison of values:

$=\dfrac{\text{Number of desktop internet user}}{\text{Number of mobile interet user}}\\\\=\dfrac{1.2\times 10^9}{4\times 10^8}\\\\=0.3\times 10\\=3$

Thus, the number of desktop internet users are 3 times more than the number of mobile internet users.

A classmate tells you, “Finding the coordinates of a midpoint is easy. You just find the averages.” Is there any truth to it? Ex

Sladkaya [172]

Yes...there is truth to what ur classmate is saying.

first of all, to find the average of something, u add up all the numbers in ur data, and divide by how many numbers there are.

the midpoint formula : ((x1 + x2)/2 , (y1 + y2)/2)

so lets say ur points are (2,4) and (4,6)

so ur going to add ur x terms (2 + 4)....then divide by 2 (because there are 2 numbers)...so ur basically taking the average of ur two x terms.
you do the same with the y terms.

midpoint is : ((2 + 4)/2 , (4 + 6)/2) = (6/2 , 10,2) = (3,5)

3. Find the equations of the lines that form the sides to the polygon shown below. What type of polygon is it? Explain your reas

borishaifa [10]

Answer: The question is not complete. the figure is attached below.

The polygon is a rectangle.

Step-by-step explanation:

Line 1 goes through (-2, 3)

hence the slope of line 1 = -3/2

Line 2 goes through (0, 3) (2, 0)

hence the slope of line 2 = -3/2

Line 3 goes through (0, 1) (-3, 1)

hence the slope of line 3 = 2/3

Line 4 goes through (3, 0) (0, -2)

Hence the slope of line 4 = 2/3

therefore -3/2 * 2/3 = -1

Line1 + Line3 Line1 + Line4 Line2 + Line3 Line2+Line4

because, the distance between Line1 and Line2 is not equal to that Line3 and Line4.

The polygon is a rectangle polygon.
