a. No, the lines have unequal slopes.
b. Yes, the lines are both vertical.
c. Yes, the lines have equal slopes.
d. No, one line has slope, while the other has no slope.

Answers

Answer 1
Slope PQ
m = (y2 - y1)/(x2 - x1)
y2 = 8
x2 = - 1
m = (8 - 5)/(-1 - 0)
m = 3/-1 = -3

Slope RS
m = (y2 - y1)/(x2 - x1)
y2 = 3
x2 = 3
m = (3 - - 1)/(3 - 5)
m = 4/-2 = -2

Conclusion
The slopes are not either 0 or undefined. They are not vertical or horizontal. They are not related by m1*m2 = -1 so they do not relate by right angles. They are not the same.

This is the future value quadrupled in t years at an annual interest rate of 6.5% compounded daily.  We need to find t.

An electronics superstore normally sells a new smartphone for $200, but it is currently offering a 50% discount off the price. The same phone is available online for $200; the website is offering 25% off the phone, plus another 25% discount off all purchases. Where should you buy the phone to get the better deal? Why?

Answers

You should buy the phone with the 50% discount.

If you buy this phone, the cost will be $100.  If you buy it through the website, you would first take 25% off:

200-(0.25*200) = 150

Then you take another 25% off:
150 - (0.25*150) = 112.50.

It is cheaper to take the 50% discount.

You should buy the phone at the electronic superstore at a 50% discount to get a better deal compared to the website.

What is the percentage?

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 3% is two-hundredth, which means 3%=3/100=0.03.

Given that the cost of a smartphone =  $200

Discount offer = 50% off

So the amount to be paid = $200 - 0.50 × $200 = $100

Now by purchasing through the website cost of a smartphone = $200

Discount 25% so it will be $200 -0.25 × $200 = $150.

Other 25% off will be $150 - 0.25×$150 = $112.5 hence, it will good to buy the phone at the electronics superstore.

Final answer:

The number that when multiplied by itself 3 times equals 125 is 5.

Jordan places two boards end to end to make one shelf. The first one is 47/100 meter long. The second board is 5/10 meter long. What is the total length, in meters, of the two boards

Answers

The total length of the two boards will be given by:
Total=(length of board A)+(length of board B)
=47/100+5/10
making the fractions have the same denominator we multiply the numerator and denominator of the second fraction by 10, this will giv us the expression of:
47/100+50/100
=97/100 m

Final answer:

To calculate the total length of the boards, the first board at 47/100 meters (0.47 meters) is added to the second board at 5/10 meters (0.5 meters), resulting in a total length of 0.97 meters.

Explanation:

To find the total length of the two boards placed end to end, we simply add the lengths of the individual boards. The first board is 47/100 meters long, and the second board is 5/10 meters long.

The second board's length can be simplified as 5/10 is equivalent to 1/2, which is 0.5 in decimal form. Adding the lengths together, we get:

Length of board 1: 47/100 meters (or 0.47 meters)
Length of board 2: 5/10 meters (or 0.5 meters)

Total length = 0.47 meters + 0.5 meters
Total length = 0.97 meters

Therefore, the total length of the two boards when placed end to end is 0.97 meters.

Work out the area of rectangle APQR.

Answers

The rectangle diagonally into 2 right triangles: one with base 5 and height 13, another with base 12 and height 5. Doubling their areas (5*13+12*5) gives 180!

The area of a rectangle with a base of 5 cm and a height of 13 cm is indeed 180 square centimeters..

Here's a simpler explanation:

Imagine slicing the rectangle diagonally into two right triangles. One triangle has base 5 cm and height 13 cm. The other triangle has base 12 cm and height 5 cm (using Pythagoras to find the missing side).

Now, the area of the rectangle equals the sum of the areas of these two triangles. Adding their areas (5 * 13 + 12 * 5) gives us 65 + 60, totaling 180 square centimeters.

Therefore, the true area of the rectangle is 180 square centimeters, not 65 or any multiple of the individual base and height alone. This hidden relationship between the diagonal and sides creates the surprising answer.

This can be done with a dilation followed by a rotation.

When you plot the points and compare the coordinates, you can see that the coordinates of E, the image of A, are cut in half, the x- and y-values are swapped, and the y-value is negated.  A dilation will cut it in half, and a rotation will swap the coordinates and negate them.

Quadrilateral ABCD can be mapped onto quadrilateral EFGH by applying a factor scale of sqrt{2/3}, then by translating each vertex using the coordinates of quadrilateral EFGH. By performing these geometric transformations, you will find that the two quadrilaterals are similar.

This is a problem of mathematical transformation in the field of geometry. Quadrilateral ABCD can be mapped onto quadrilateral EFGH using a scale factor followed by a translation.

First, let's find the scale factor. The distance from A(-9,5) to B(-7,3) is sqrt{(7+9)2 + (3-5)2} = sqrt{4+4} = 2sqrt{2}.

The distance from E(-2.5,-4.5) to F(-1.5,-3.5) is sqrt{(2.5+1.5)2+(4.5+3.5)2} = sqrt{4+8} = 2sqrt{3}.

Hence, the scale factor is 2sqrt{2}/2sqrt{3} = sqrt{2}/sqrt{3} = sqrt{2/3}.

Next, to perform the translation, shift over all the vertices of quadrilateral ABCD by adding to their x-coordinates the difference between the x-coordinate of vertex E and the x-coordinate of vertex A (which, after scaled, is -9*sqrt{2/3}), as well as similarly adding to their y-coordinates the difference between the y-coordinate of vertex E and the y-coordinate of vertex A (which, after being scaled, is 5*sqrt{2/3}).

After carrying out the scaling and translation, quadrilateral ABCD will be exactly mapped onto quadrilateral EFGH, demonstrating that the two figures are similar.

Answers

They do not occur more frequently than any other value in the distribution, the values 220, 260, 250, and 270 are not modes.

How to finding the value that appears the most frequently will help us determine the mode of a distribution.?

Distributed mode is the most common value. From the given frequency distribution we can see that both the values ​​220 and 230 occur with the highest frequencies of 6 and 7 respectively. Therefore, both 220 and 230 are modes of this distribution.

that the values ​​260, 250, and 270 are not modes, as they all have frequencies of 0 or 1. Also, the No Mode value is not a valid value in the distribution, indicating that there is no single mode value.

The values 220, 230, 240, 250, 260, and 270 all appear six times in this distribution, seven times each for values 230, seven times for values 240, one for value 250, zero for values 260, and one for value 270.

As a result, the value with the highest frequency—230—is the mode. Therefore, 230 is the mode for this distribution.

Due to the fact that they do not occur more frequently than any other value in the distribution, the values 220, 260, 250, and 270 are not modes.

Latrell is comparing two job opportunities one job will pay $12 an hour and he will work 40 hour a week. The other one pays an annual salary of $22,00 and he will work 45 hours a week. which job pays more?

Answers

To compare these two jobs, you need to have a common point. In this problem, you have to solve for the annual salary of the first job and compare it with the annual salary of the second job which is already given.

$12 per hour x 40 hours per week x 48 weeks in a year = $23,040

First job’s annual salary is $23,040

Second job’s annual salary is $22,000

Therefore, the job which pays $12 an hour pays more.

Latrell will earn more at the job that pays $12 per hour for a 40-hour workweek, which totals $24,960 per year, compared to the annual salary of $22,000 for a 45-hour workweek.

To determine which job pays more between an hourly wage job and an annual salary job, we need to calculate the total annual income for each option.

For the hourly wage job at $12 per hour for 40 hours a week:

$12/hour times 40 hours/week = $480/week$480/week times 52 weeks/year = $24,960/year

For the annual salary job of $22,000 for 45 hours a week, the total annual income is:

$22,000/year (no further calculation is needed)

Comparing the two annual incomes:

Hourly wage job = $24,960/yearAnnual salary job = $22,000/year

Therefore, the job that pays $12 per hour for 40 hours a week offers a higher annual income than the job with an annual salary of $22,000 for 45 hours a week.
