-9/2 is equal to -4.5 so you plot a point on -4.5
Answer 2
Answer:

A circular lampshade with a diameter of 14 inches has a length of wire that goes around exactly one time. How many inches of wire are needed to go around the lampshade exactly one time?

Answers

the questions is how long the circumference of the lampshade is, and that is given by:
c = diameter*pi
c = 14*3.14
c = 43.96
so, there are needed 43.96 inches of wire to go around the lampshade one time

A telephone company charges a fixed monthly rate plus a rate per megabyte of data used. The company charges $155 for 100 megabytes and $245 for 200 megabytes. An equation can be written to show the relationship between the total megabytes of data used (x) and the total monthly charges (y). Which of the following best describes the steps to draw the graph? Draw a graph that joins the points (155, 100) and (245, 200) and has a slope = 0.9 Draw a graph that joins the points (155, 100) and (245, 200) and has a slope = 1.1 Draw a graph that joins the points (100, 155) and (200, 245) and has a slope = 1.1 Draw a graph which joins the points (100, 155) and (200, 245) and has a slope = 0.9

Answers

Answer:

Draw a graph that joins the points (100, 155) and (200, 245) and has a slope = 0.9

Step-by-step explanation:

x variable represents total megabytes of data used

y variable represents total monthly charges

The company charges $155 (y) for 100 megabytes (x) means that the point (100, 155) belongs to the equation.

The company charges $245 (y) for 200 megabytes (x) means that the point (200, 245) belongs to the equation.

With these two points, the slope is computed as follows:

(245 - 155)/(200 - 100) = 0.9

-5/5/6 + 3/2/3 what is the sum and the steps?

Answers

you gotta do BEDMAS

B - well, there aren't any brackets in this equation
E - no exponents either
D - division...YES

-5/5/6 is going to be one half
3/2/3 is going to be the other
and of course, at the end, we're going to add the answers up together

because -5/5/6 are all in one big division equation, you have to calculate that first

similarly, because 3/2/3 is one big divison equation, you have to calculate that first too

and since there's no M (from BEDMAS), we move on to addition, where we take the answers of -5/5/6 and 3/2/3 and we add them

-5/5 = -1
-1/6 = -1/6 OR -0.166666666666666666...

3/2 = 3/2
(3/2) / 3 = 1/2 OR 0.5

now we do the A part; addition
(-1/6) / 1/2 = -1/3 OR .33333333333333333333333333....
