The Table Below Shows The Number Of Color Pages A Printer Prints Out Over A Period Of Time

Answers

Answer 1

Answer:

The constant of proportionality is 3/2

B is correct.

Step-by-step explanation:

We are given a table of Time (x) and Number of pages (y)

In x minutes printer prints y number of pages.

As we know the it would be direct proportion because if time increase number of printing page increase.

Thus, y=kx

x is time ( independent variable)

y is number of pages (dependent variable)

k is constant of proportionality.

From table we will take the value of x and y and to solve for k

x=2, y=3

3=2k

[tex]k=\dfrac{3}{2}[/tex]

Hence, The constant of proportionality is 3/2

Answer 2

Answer:

Option B) [tex]\frac{3}{2}[/tex]      

Step-by-step explanation:

We are given the following information in the question:

A table showing the number of pages printed(y) in time(x).

x:       2       6       8       18

y:       3        9      12       27

We have to find the constant of variation.

Constant of variation

It is the number that relates two variables that are directly proportional or inversely proportional to one another.y = kx, k is the constant of proportionality.

Constant of variation =

[tex]\displaystyle\frac{y_2-y_2}{x_2-x_1}\\\\(x_1.y_1), (x_2,y_2)\text{ are the points belonging to the given table.}[/tex]

Putting the values, we get:

[tex]\text{Constant of variaion} = \displaystyle\frac{9-3}{6-2} = \frac{12-9}{8-6} = \frac{27-12}{18-8} = \frac{3}{2}[/tex]

Hence, the constant of variation is [tex]\frac{3}{2}[/tex]

A toll collector on a highway receives ​$4 for cars and ​$9 for buses. At the end of a 2​-hour ​period, she collected ​$188. How many cars and buses passed through the toll booth during that​ period? List all possible solutions.

Answers

One answer is 2 cars and 20 buses

Final answer:

The toll collector collected $188 in a 2-hour period. There are three possible solutions: 44 cars and 12 buses, 35 cars and 18 buses, or 26 cars and 24 buses.

Explanation:

Let's assume the number of cars passing through the toll booth is 'x' and the number of buses is 'y'.

We can form the following equations based on the given information:

4x + 9y = 188  (total amount collected)

2x + 2y = 2  (total number of hours)

Now we can solve these equations simultaneously to find the values of 'x' and 'y'.

Using substitution or elimination method, we can find that 'x = 44' and 'y = 12', or 'x = 35' and 'y = 18', or 'x = 26' and 'y = 24'.

Therefore, there are three possible solutions:

C
c. do any lines have an undefined slope?
Yes, line A has zero shape

No, a line with undefined slope is vertical and none
of the lines are vertical

No, a line with undefined slope is horizontal and none of the lines are horizontal

Answers

Final answer:

A positive slope is represented by an upward tilt, Line A has the steepest slope, and none of the lines have an undefined slope.

Explanation:

In this case, line A represents a positive slope because it is a straight line that has an upward tilt or is increasing as we move from left to right. Line B represents a negative slope because it is a straight line that has a downward tilt or is decreasing as we move from left to right. Line C represents zero slope because it is a horizontal line without any tilt or change in y-values as we move along the x-axis.

To determine which line has the steepest slope, we need to look at the lines' tilt more closely. Line A has a steep positive slope as it increases quickly, while Line B has a less steep negative slope as it decreases slowly. Line C has a slope of zero, so it does not have any steepness. Therefore, Line A has the steepest slope.

None of the lines have an undefined slope. An undefined slope occurs when a line is vertical. Since none of the lines are vertical, they all have defined slopes.

For f(x) = 7x +2, Find F(x) When X=0 And When X=1. Can Someone Please Help Me!!!

Answers

Hey there!

First, we'll solve for x = 0.

The first step is to replace x with 0 anytime it appears in the equation.

f(0) = 7(0) + 2

Multiply 7 by 0 next because multiplication comes before addition in PEMDAS.

f(0) = 0 + 2

Then, add 2 to 0 since it is the last step.

f(0) = 2   The value of f(x) when x = 0 is 2.

Now we can solve for x = 1.

The first step is to replace x with 1 anytime it appears in the equation.

f(1) = 7(1) + 2

Multiply 7 by 1 next because multiplication comes before addition in PEMDAS.

f(1) = 7 + 2

Then, add 2 to 7 because it is the last step.

f(1) = 9   The value of f(x) when x = 1 is 9.

some one help me with problems 1,2,3 plz.thank you !

1.  Straight lines are 180 degrees.  That means 180-126=x.  So, x=54.  

You can then use x to find y.  180-54=y.  y=126.  OR  You can use vertical angles to find y.  Vertical angles are the same degree.  So if y is vertical to the angle with 126 degrees, then y=126.

Either way, you will get x=54 and y=126.

2.  You would solve problem 2 the same way as problem 1.  I encourage you to try to do it yourself, but here's how you would do it.

180-103=y, so y=77.  You can either use vertical angles or x=180-77 to find x.  You will end up with x=103.

So y=77 and x=103.

3.  Here you would use vertical angles.  Remember, vertical angles have the same degree!  So 2x+29=5x+20.  Then all you have to do is solve it.

You would end up with x=3.

A street sign company is making street signs in the shape of equilateral triangles. The side length of each sign is 22 inches. What is the exact altitude length so that the company will be able to know what size box to ship them in?

Answers

Answer: 11 sqrt3


Well, since this is an equilateral triangle, you know that all of the sides have the same length: 22 inches. If you want to find the altitude (height), you would have to use the Pythagorean theorem: a^2 + b^2 = c^2

This means that the sum of the two legs squared is equal to the hypotenuse of the triangle squared.

We already know that the hypotenuse is 22 inches, so we can plug that in as c.

We also know that to make the triangle a right triangle, we will need to halve the bottom side, getting 11 inches, which we can plug in as b.

Lastly, we need to know a, so that is our variable to solve (the height). Here is the equation:

a^2 + (11^2) = (22^2)

This is equal to:

a^2 + 121 = 484

Now subtract 121 from both sides to get a^2 on its own:

a^2 = 363

Lastly, take the square root of both sides to solve for a:

a = 11 sqrt3


Final answer:

The altitude of an equilateral triangle with a side length of 22 inches is 11√3 inches.

Explanation:

The altitude of an equilateral triangle can be found using the formula  altitude = (side length * √3) / 2.

In this case, the side length of the street sign is 22 inches. Plugging this value into the formula, we get:

altitude = (22 * √3) / 2.

Simplifying, we have:

altitude = 11√3 inches.

Therefore, the exact altitude length is 11√3 inches.

Now arrange

d/c = 7.5/9

d/c = 75/90

d/c = 5/6

The value of d/c is 5/6

In order to find this, we need to simply replace the values of the triangles that match up. The d portion would match up with 7.5 and the c portion would match up with the 9. So, we can put them into the equation and simplify.

d/c = 7.5/9

d/c = 5/6

carlos estimates that he will need to earn at least $700 to take his girlfriend to the prom. carlos works two jobs as show in the table jobs main st. Deli $8 per hour and babysitting $6 per hour. A. write an inequality to represent this situation B. Graph the inequality. C. will he make enough money if he works 50 hours at each job?

Answers

for the deli job he will make 400 and for the other job he makes 300. so he has just enough

Answer:

The required inequality is: [tex]8x+6y\geq 700[/tex]

The required graph is shown in figure 1.

Yes, he make enough money.

Step-by-step explanation:

Consider the provided information.

Part (A)

Carlos estimates that he will need to earn at least $700 to take his girlfriend to the prom.

Let the number of hours worked in Deli is x and the number of hours worked for babysitting is y.

Deli $8 per hour and babysitting $6 per hour. Carlos need to earn at least 700.

For at least use the inequity ≥

The required inequality is: [tex]8x+6y\geq 700[/tex]

Part (B)

Rewrite the inequity as an equation to find the the x and y intercept.

[tex]8x+6y=700[/tex]

Substitute x=0 in the above

[tex]8(0)+6y=700[/tex]

[tex]y=\frac{700}{6}[/tex]

[tex]y= 116.67[/tex]

Substitute y=0 in the above

[tex]8x+6(0)=700[/tex]

[tex]x =\frac{700}{8}[/tex]

[tex]x= 87.5[/tex]

Use the point (0,116.67) and (87.5,0) to draw the graph.

Since the sign of inequality is greater than equal to, so shade the graph above the line. Use solid line as the sign of inequality is ≥.

Thus, the required graph is shown in figure 1.

Part (C)

We need to find he make enough money if he works 50 hours at each job.

Substitute x=50 and y=50 in the inequality.

[tex]8(50)+6(50)\geq 700[/tex]

[tex]400+300\geq 700[/tex]

[tex]700\geq 700[/tex]

Which is true.

Hence, he make enough money.

B. 54.0861
C. 5.4861
D. 0.54861

Answers

the answer might be B. I'm happy to help you out
Final answer:

The equivalent number to the given equation is 54.861, calculated by using the order of operations and understanding of place value.

Explanation:

To solve this problem, you need to understand the concept of place value and order of operations in mathematics. Given the equation 5*10 + 4*1 + 8*1/10 + 6*1/100 + 1*1/1,000, we can begin solving using the order of operations, which is often remembered as PEMDAS - Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

Here, we multiply before adding. The solution would look like this:

5*10 = 504*1 = 48*1/10 = 0.86*1/100 = 0.061*1/1,000 = 0.001

Adding these results together, you get 50 + 4 + 0.8 + 0.06 + 0.001 = 54.861

So the equivalent number is 54.861, which corresponds to answer choice A.

One week anil earned $4 per hour. The next week he earned $4.50 per hour. What was the percent increased in his hourly rate?

Answers

12.5
is the correct answer

The percent increase in Anil's hourly wage from $4 to $4.50, find the difference ($0.50), divide it by the original wage ($4), and multiply by 100, resulting in a 12.5% increase.

The student is asking how to calculate the percent increase in Anil's hourly wage from one week to the next. He was earning $4 per hour and then began to earn $4.50 per hour. The percentage increase is found by dividing the change in the quantity (the increase in pay) by the original quantity (the original pay) and then multiplying by 100 to get a percent.

To calculate the percentage increase:

Find the difference in pay: $4.50 - $4 = $0.50.

Divide this difference by the original pay: $0.50 / $4 = 0.125.

Multiply by 100 to get the percentage: 0.125 × 100 = 12.5%.

Therefore, the percent increase in Anil's hourly rate is 12.5%.

Answers

Since it is perp. to y = 5x +4, the slope would be the negative reciprocal of 5, which is -1/5. In order to find the y-in. you have to plug in the values you already know into y=mx+b.

-2 = -1/5(3) + b

b=-7/5

y = -1/5x -7/5

Final answer:

The equation of the line perpendicular to y = 5x + 4 and passes through the point (3, -2) is y = -1/5x - 7/5.

Explanation:

The standard form equation of a line is y = mx + b, where m is the slope and b is the y-intercept. The question provides a line equation y = 5x + 4 and informs that the desired line is perpendicular to it. Two lines are perpendicular if the product of their slopes is -1. Hence, the slope of the perpendicular line will be the negative reciprocal of 5 which is -1/5.

Then to find the y-intercept, we use the point that the line passes through which is (3, -2). Insert these values into the equation:y = mx + b, so -2 = -1/5(3) + b, solve to find b = -7/5.

Therefore, the equation of the line in standard form is y = -1/5x - 7/5.
