Answer:

28.5% Internet users in 2003 were in the United States.

Step-by-step explanation:

We are given the following in the question:

Number of people using the internet =

$5.8078 \times 10^8$

Number of people in United States =

$1.6575 \times 10^8$

Percent of Internet users in 2003 were in the United States =

$=\dfrac{\text{Number of users in United States}}{\text{Number of internet user in world}}\times 100\%\\\\=\dfrac{ 1.6575 \times 10^8}{5.8078 \times 10^8}\times 100\%\\\\=28.5\%$

Thus, 28.5% Internet users in 2003 were in the United States.

Can someone plz help me with this and i need the drawing to show work

Burka [1]

Answer:

20.833 feet

Step-by-step explanation:

The light reflects off the mirror at the same angle that it hits it at. So the triangle formed by the beam and mirror is similar to the triangle formed by Kevin and the mirror.

Therefore, we can write and solve a proportion.

h / 10 = 6.25 / 3

h = 20.833

The beam is 20.833 feet tall.
