HELP ASAP! The number of entertainment websites in 1995 wass 54. By 2004 there were 793 entertainment website..

AleksandrR [38]

<h3>Answer: Choice A. 82 websites per year</h3>

=============================================================

How I got that answer:

We have gone from 54 websites to 793 websites. This is a change of 793-54 = 739 new websites. This is over a timespan of 2004-1995 = 9 years.

Since we have 739 new websites over the course of 9 years, this means the rate of change is 739/9 = 82.1111... where the '1's go on forever. Rounding to the nearest whole number gets us roughly 82 websites a year.

----------

You could use the slope formula to get the job done. This is because the slope represents the rise over run

slope = rise/run

The rise is how much the number of websites have gone up or down. The run is the amount of time that has passed by. So slope = rise/run = 739/9 = 82.111...

In a more written out way, the steps would be

slope = rise/run

slope = (y2-y1)/(x2-x1)

slope = (793 - 54)/(2004 - 1995)

slope = 739/9

slope = 82.111....

Find the volume of the cone. Round your answer to the nearest tenth.

oee [108]

Answer:

15205.3

Step-by-step explanation: H=30 R²=484 3.14=π →= rounded up to tenth V = Volume

formula (no numbers): H x R² x π ÷  $\frac{1}{3}$  (or 3) = V

how i got the answer : 30 x 484 x 3.14 ÷ 3 = 15205.31 → 15205.3

We have been given that a colleague has been tutoring six students in 11th grade to prepare for the ACT. Student scores were as follows: 20, 18, 16, 15, 23, 20. We are asked to find the mean of the ACT scores.

We will use mean formula to solve our given problem.

$\text{Mean}=\frac{\text{Sum of terms}}{\text{Number of terms}}$
