A copy center offers its customers two different pricing plans for black and white photocopies of 8.5 in. by 11 in. pages. Customers can either pay $0.08 per page or pay $7.50 for a discount card that lowers the cost to $0.05 per page. Write and solve an equation to find the number of photocopies for which the cost of each plan is the same.
.08c = .05c + 7.50; c = 250
.05c = .08c + 7.50; c = 22.5
.08c = .05c – 7.50; c = 250
7.50 = .08c + .05c; c = 58
Answer:
.08c=.05c-7.50; c=250

angle 2 = 140 b. _____________.
angle 5 and angle 2 are supplementary angles c.________.
Angle 5 and angle 2 are same-side interior angles d._________.
a is a parallel to b e._______
The provided statements are either given information, interpretations from the given diagram or applying rules of geometry such as the definitions of supplementary angles and the Same-Side Interior Angles Theorem.
Explanation:The missing reasons in this geometric proof are as follows:
a. Given: The fact that angle 5 = 40 is simply provided, it's the given information in the question.
b. Given: Similarly, the measurement of angle 2 being 140 is given information.
c. Definition of supplementary angles: Angle 5 and angle 2 are supplementary because the sum of their measure equals 180 (40+140).
d. Interpretation of the diagram: Without a diagram, it's difficult to be precise, but if angle 5 and angle 2 are indicated as same-side interior angles, then this inference comes from interpreting the diagram.
e. Same-Side Interior Angles Theorem: Lastly, if the same-side interior angles are supplementary, then the lines are parallel. This is a rule encapsulated by the same-side interior angles theorem.

What is the relationship between the sine and cosine of complementary angles in a right triangle? Please give an example to support your answer.
Final answer:
The sine and cosine of complementary angles in a right triangle are equal to each other but reversed, because the opposite side for one angle is the adjacent side for the other, relative to the hypotenuse.
Explanation:
The relationship between the sine and cosine of complementary angles in a right triangle is that they are equal to each other but reversed. If one angle is x and its complementary angle is 90° - x (because complementary angles add up to 90°), then the sine of x is equal to the cosine of its complementary angle, and vice versa.
This is because, in a right triangle, the side that is the opposite side for one angle becomes the adjacent side for the complementary angle, relative to the hypotenuse which remains the same for both angles.
For example, in a right triangle with one acute angle of 30°, its complementary angle is 60°. The sine of 30° is 1/2, and the cosine of 60° is also 1/2. Similarly, the cosine of 30° is [tex]\sqrt{3/2[/tex], and the sine of 60° is [tex]\sqrt{3/2[/tex] shows a complementary relationship.

WXY is an isosceles triangle with line WX congruent to line WY. if WX is 3 more than four times x, XY is 7 less than five times x, and WY is 66 less than seven times x, find x and the measure of each side.
Answer:
x=10
Step-by-step explanation:
part 1:
4x+3=5x-7
(subtract 4x from 5x to get 1x and add 7 to 3 to get 10)
1x=10
x=10
part 2:
WX=4(10)+3=43
XY=5(10)-7=43
WY=7(10)-66=4
An isosceles triangle, have two congruent sides.
The value of x is 23The measure of each side is 95, 95 and 108From the question, we have the following highlights
[tex]\mathbf{WX = WY}[/tex]
[tex]\mathbf{WX = 3 + 4x}[/tex]
[tex]\mathbf{XY = 5x - 7}[/tex]
[tex]\mathbf{WY = 7x - 66}[/tex]
(a) Find x
We have:
[tex]\mathbf{WX = WY}[/tex]
Substitute values for WX and WY
[tex]\mathbf{3 + 4x = 7x - 66}[/tex]
Collect like terms
[tex]\mathbf{7x - 4x = 3 + 66}[/tex]
[tex]\mathbf{3x = 69}[/tex]
Divide both sides by 3
[tex]\mathbf{x = 23}[/tex]
Hence, the value of x is 23
(b) The measure of each side
Substitute 23 for x in:
[tex]\mathbf{WX = 3 + 4x}[/tex]
[tex]\mathbf{XY = 5x - 7}[/tex]
[tex]\mathbf{WY = 7x - 66}[/tex]
[tex]\mathbf{W = 3 + 4 \times 23}[/tex]
[tex]\mathbf{W = 95}[/tex]
[tex]\mathbf{XY = 5x - 7}[/tex]
[tex]\mathbf{XY = 5 \times 23 - 7}[/tex]
[tex]\mathbf{XY = 108}[/tex]
[tex]\mathbf{WY = 7x - 66}[/tex]
[tex]\mathbf{WY = 7 \times 23 - 66}[/tex]
[tex]\mathbf{WY = 95}[/tex]
Hence, the measure of each side is 95, 95 and 108

In a salsa recipe, the number of tomatoes added is proportional to the amount of salt added. This graph shows the relationship.
What is the unit rate for the number of tomatoes to the tsp of salt?
Answer:
The unit rate for the number of tomatoes to the tsp of salt is 3.
Step-by-step explanation:
Consider the provided graph.
The equation of the line is [tex]y=3x[/tex]
A unit rate is a rate with 1 in the denominator.
Here, the meaning of unit rate is how much tomatoes to the tsp of salt.
As we know the slope intercept form is:
[tex]y = mx + b[/tex]
Where, m is the slope of the line or rate and b is y intercept.
By the comparison we can say that the slope of the line is 3. Here, the denominator is 1.
This shows that 3 tomatoes are added for each teaspoon of salt.
Hence, the unit rate is 3.
A giraffe can run 32 miles per hour. What is this speed in feet per second? Round your answer to the nearest tent.
Speed is the rate of change of distance over time.
The speed in feet per seconds is 46.9
The speed of the giraffe is given as:
[tex]\mathbf{Speed = 32 miles/hour}[/tex]
Start by converting miles to feet
To do this, we multiply 32 by 5280.
So, we have:
[tex]\mathbf{Speed = 32 \times 5280feet/hour}[/tex]
[tex]\mathbf{Speed = 168960feet/hour}[/tex]
Next, convert hour to seconds
To do this, we divide by 36000.
So, we have:
[tex]\mathbf{Speed = \frac{168960}{3600} feet/seconds}[/tex]
[tex]\mathbf{Speed = 46.9 feet/seconds}[/tex]
Hence, the speed in feet per seconds is 46.9

Sally has 42 coins, all dimes and nickels, that have a total value of $3.00. How many nickels does she have?
Sally has 24 nickels.
Explanation:To determine the number of nickels Sally has, we can set up a system of equations using the given information. Let's assume Sally has x nickels and (42 - x) dimes. The value of the nickels is 5x cents, and the value of the dimes is 10(42 - x) cents. We can set up the equation: 5x + 10(42 - x) = 300 (since the total value is $3.00).
Simplifying the equation, we get: 5x + 420 - 10x = 300. Combining like terms, we have: -5x + 420 = 300. Subtracting 420 from both sides gives us: -5x = -120. Dividing both sides by -5, we find x = 24.
Therefore, Sally has 24 nickels.

Two expressions with equal sign is equation. C=a-4b-11/-4 is the solution for c when given equation is A=11+4b-4c. Option A is correct.
What is equation?Two expressions with equal sign is called as equation.
Given equation,
a= 11 + 4b - 4c
We need to separate c from equation,
-4c = a - 11 - 4b
Divide both sides by -4
c=(a-11-4b)/-4
Therefore option A is correct for equation A=11+4b-4c.

Write the next three terms and write a rule to describe the number pattern. 0.57, 0.66, 0.75, 0.84, . . .
The next three terms in the number pattern 0.57, 0.66, 0.75, 0.84 are 0.93, 1.02, and 1.11. The rule for the pattern is that each term increases by 0.09 from the previous term.
Explanation:The given sequence is: 0.57, 0.66, 0.75, 0.84, ... The step or difference between each consecutive term is 0.09. Therefore, the next three numbers in the sequence would be: 0.84 + 0.09 = 0.93, 0.93 + 0.09 = 1.02, 1.02 + 0.09 = 1.11. So the answer is 0.93, 1.02, 1.11.
The generalized rule for this series is that each term increases by 0.09 from the previous term. In mathematical terms, if we denote the nth term as Tn, then Tn+1 = Tn + 0.09. This rule tells us that the number pattern involves adding 0.09 for each subsequent term in the sequence.
