The slope of parallel line is -6/5

What is slope?

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx

where, m is the slope

given:

Equation: 18x + 15y = 90.

Now, writing the given equation in slope intercept form

15y= 90- 18x

y= 90/15 - 18/15 x

y= 6 - 6/5x

So, the slope of given line is -6/5

Now, the slope of parallel and given is same.

Thus, the slope of parallel line is -6/5

At a farm market, watermelons are selling 5 for $20. Each watermelon weighs about 8 pounds. What does the unit rate tell you? Responses The number of pounds each watermelon weighs. The number of pounds each watermelon weighs. The number of pounds all of the watermelons weigh. The number of pounds all of the watermelons weigh. The cost of all the watermelons. The cost of all the watermelons. The cost of one watermelon. The cost of one watermelon.

Answers

The unit rate of the watermelons would tell us the cost of 1 of the watermelon. The last option is correct.

How to solve for the cost

The question tells us that the melons are sold for 5 for $20.

Hence the price of 1 would be at: 20/5

= 4 dollars per watermelon.

The weight of one of the melons is 8 pounds and the unit rate for 1 is 4 dollars. The unit rate is the price per one of the fruits or the cost of the fruit.

In 4 games, Larry averaged 23 PPG (points per game). How many points does he need to score in the last game to have an average of 25 PPG? Explain how to use the mean and data given to find the answer.

Answers

The points does he need to score in the last game to have an average of 25 PPG is 33 points

Larry will need 33 points in his 5th game to average 25 PPG.

Given that

Larry averaged 23 PPG (points per game) in 4 games.

To find

How many points are required to have an average of 25 PPG?

So, according to the question

We have,

Larry's average in 4 games = 23 PPG.

        ∵ [tex]average = \frac{sum\;of\;terms}{number\;of\;terms}[/tex]

        ∴ Total points gained by Larry in 4 games

                         = (average points in 4 games) × 4

                         =  23 × 4

                         =  92 points.

Let's assume Larry scored x points in the 5th match to have an average of 25 PPG.

So, we can say that

        Larry's average in 5 games = [tex]\frac{total\;points\; in\; 5\;games}{5}[/tex]

                                                 25 = [tex]\frac{92+x}{5}[/tex]

                                           25 × 5 = 92 + x

                                                125 = 92 + x

                                                    x = 125 - 92

                                                    x = 33.

Answers

Using the monthly payment formula, it is found that the best plan is given by:

The monthly credit card payment would be $238.37, which is lower than the monthly payment on the bank loan.

What is the monthly payment formula?

It is given by:

[tex]A = P\frac{\frac{r}{12}\left(1 + \frac{r}{12}\right)^n}{\left(1 + \frac{r}{12}\right)^n - 1}[/tex]

In which:

P is the initial amount.r is the interest rate.n is the number of payments.

For the simple interest payment method, the parameters are given as follows:

r = 0.06, n = 3 x 12 = 36, P = 11000, r/12 = 0.06/12 = 0.005.

Hence:

[tex]A = P\frac{\frac{r}{12}\left(1 + \frac{r}{12}\right)^n}{\left(1 + \frac{r}{12}\right)^n - 1}[/tex]

[tex]A = 11000(0.005)\frac{(1.005)^{36}}{(1.005)^{36} - 1}[/tex]

A = 334.64.

For the credit card payment method, the parameters are given as follows:

r = 0.16, n = 6 x 12 = 72, P = 11000, r/12 = 0.16/12 = 0.0133.

Hence:

[tex]A = P\frac{\frac{r}{12}\left(1 + \frac{r}{12}\right)^n}{\left(1 + \frac{r}{12}\right)^n - 1}[/tex]

[tex]A = 11000(0.0133)\frac{(1.0133)^{72}}{(1.0133)^{72} - 1}[/tex]

A = 238.37.

The monthly credit card payment would be $238.37, which is lower than the monthly payment on the bank loan.

You want to enlarge a 4 x 5 inch photo to fit into a 1 inch wide frame
that has an outer perimeter of 53 inches.

a. Write and simplify an equation for the outer perimeter of the
picture frame.

b. Determine the factor by which you must enlarge the picture to have it completely fill the inside of the picture frame

Answers

The 4•x by 5•x inner dimensions of the 53 inches outer perimeter picture frame, the 1 inch wide frame and the 4 × 5 inch picture to be enlarged, gives;

a. The outer perimeter equation is presented as follows;

18•x + 8 = 53 inches

b. The scale factor required for the enlargement of the picture is 2.5

Which method can be used to write the equation and find the scale factor?

The dimensions of the photo = 4 × 5 inch

Width of the frame = 1 inch

Outer perimeter of the frame = 53 inches

The width of the inside of the picture frame = 4•x

The height of the inside of the picture frame = 5•x

a. The equation for the outer perimeter of the picture frame is therefore;

2 × (4•x + 1 + 1) + 2 × (5•x + 1 + 1) = 53

Which gives;

2 × (4•x + 2) + 2 × (5•x + 2) = 53

8•x + 4 + 10•x + 4 = 53

A simplified equation for the outer perimeter of the picture frame is therefore;

18•x + 8 = 53

b. Solving the above equation, we have;

18•x + 8 = 53

18•x = 53 - 8 = 45

18•x = 45

Therefore;

x = 45 ÷ 18 = 2.5

x = 2.5

The width and height of the picture frame are therefore;

Width = 4•x = 4 × 2.5 = 10

Height = 5•x = 5 × 2.5 = 12.5

Which gives;

Width = 10 inches

Height = 12.5 inches

The enlargement factor, sf, is given by the ratio of a side of the picture frame to a side of the picture as follows;

sf = 12.5/5 = 2.5

The factor by which to enlarge the picture frame is 2.5

The equation representing the minimum and maximum scores |x-87| = 1.8

Given that the average score on a lab report is 87 points. All students score within 1.8 points of the average.

Let 'x' be the score of student. The maximum and minimum score of a student lies within 1.8 points of the average.

Then, maximum score of a student, x = 87+1.8

and minimum score of a student, x = 87-1.8

D=63-h(10 - c) Given: D = distance in miles, h = number of hours, c = speed of the river's current in mph What is a correct formula for the boat's distance from its destination after 3 hours​

Answers

The distance of the boat from its destination depends on

Speed of the boatSpeed of the river currentDirection of the river current.

So with these factors, the distance of the boat from its distance can be calculated.

The distance of the boat from the destination currently is 63 miles

Speed of the boat is 10 miles / hr

Let c be the speed of the river current and

h be the number of hours to reach a particular destination

So, the formula to find the distance of the boat from destination is given by

D = 63 - h(10 - c)

We need to find the formula for boat's distance from its destination after 3 hours

Thus h = 3 hrs

Let us substitute h in above equation, Then

D = 63 - 3(10 - c)

D = 63 - 30 - 3c

D = 33 - 3c

which is the formula for the boat's distance from its destination after 3 hours.
