Over what range of pages will Edie pay less by using the first printer ? A. Less than 100 pages B. More than 100 pages C. Less than 50 pages D. More than 50 pages E. More than 100 pages but less than 200 pages

Answers

Answer:

A) less than 100 pages

Step-by-step explanation:

p = # pages

Printer 1:

y = .25p + 5

Printer 2:

y = .20p + 10

.25p + 5 < .20p + 10

.05p + 5 < 10

.05p < 5

p < 5/.05

p < 100

A billiard ball is struck by a cue. It travels 120 cm before ricocheting off a rail and traveling another 100 cm into a corner pocket. The angle between the path as the
ball approaches the rail and the path after it strikes the rail is 40 degrees. How far is
the corner pocket from where the cue initially struck the ball? Round your answer to the nearest centimeter.

Answers

The angle between incident and reflection is 45 degrees not 90 degrees, so we need to use the cosine rule:
 
a^2 = 100^2 + 120^2 - 2*100*120*cos(45°)   where a is the distance  between pocket and initial strike.
 
so a = sqrt(100^2 + 120^2 - 2*100*120*cos(45°))
 
a = 86 cm (to the nearest cm).

What is X equal to if 1X+30=6X+20?

Answers

Answer:

x=2

Step-by-step explanation:

1*x+30=6x+20

Multiply 1*x=x

x+30=6x+20

Subtract 30 from both sides:

x+30-30=6x+20-30

Simplify:

x=6x-10

Subtract 6x from both sides

x-6x=6x-10-6x

Simplify:

-5x=-10

Divide both sides by -5

-5x/5=-10/-5

Which is one reason why this expression is equal to 0?
[tex]8.29 \times \frac{ - 5.62 + 5.62}{5.62} [/tex]
​

Answers

Answer:

0

Step-by-step explanation:

The given expression is :

[tex]8.29 \times \frac{ - 5.62 + 5.62}{5.62}[/tex]

We can solve the expression as follows :

[tex]\frac{ - 5.62 + 5.62}{5.62}=\dfrac{0}{5.62}[/tex] (As -5.62+5.62 equals to 0)

Any number multipled to 0 gives 0.

Hence, the value of the given expression is equal to 0.

Answers

Answer:

[tex]y - 15 = 5(x-3)[/tex]

Step-by-step explanation:

Equation of a line:

The equation of a line, in point slope form, is given by:

[tex]y - y_0 = m(x - x_0)[/tex]

In which the point is [tex](x_0,y_0)[/tex] and m is the slope.

3/15

This means that [tex]x_0 = 3, y_0 = 15[/tex]

So

[tex]y - 15 = m(x - 3)[/tex]

Finding the slope:

Suppose we have two points. The slope is given by the change in the output divided by the change in the input.

3/15

5/25

Change in the output: 25 - 15 = 10

Change in the input: 5 - 3 = 2

So

[tex]m = \frac{10}{2} = 5[/tex]

The equation is:

[tex]y - 15 = 5(x-3)[/tex]
