The constant of proportionality is 0.25

Using the unitary approach, you can solve problems by first figuring out the value of a single unit, then multiplying that value by the number of units you need.

According to the given information

Applying Unitary Method

Pages have a direct relationship with time.

N ∝ t

N = k × t

k is constant of proportionality

Time taken to read 15 pages = 60 minutes

Time taken to read 1 page = [tex]\frac{15}{60}[/tex]

                                            = 1/4

1/4 is constant of proportionality

Answer:

they will probably contact them orrr charge late  fees

The first thing a lender might do if a borrower is late with a payment is to send a reminder.

This reminder will usually be a phone call, email, or letter. The reminder will typically state the amount that is due, the due date, and any late fees that may be charged.

If the borrower does not make the payment after receiving the reminder, the lender may then contact the borrower directly. This contact may be made by a phone call, email, or letter. The lender may also try to work with the borrower to come up with a payment plan.

If the borrower still does not make the payment, the lender may then report the borrower to the credit bureaus. This will have a negative impact on the borrower's credit score. The lender may also start legal proceedings to collect the debt.

The specific steps that a lender will take if a borrower is late with a payment will vary depending on the lender's policies and the borrower's situation. However, sending a reminder is usually the first step.

Here are some additional things that a lender might do if a borrower is late with a payment:

Charge late fees.

Terminate the loan.

Sue the borrower.

Foreclose on the borrower's property.

It is important to note that the lender's actions will also depend on the terms of the loan agreement. The loan agreement will typically specify what happens if a borrower is late with a payment.

If you are a borrower who is late with a payment, it is important to contact your lender as soon as possible. You should try to work out a payment plan with the lender. If you do not make the payment, the lender may take legal action against you.

Answer:

Step-by-step explanation:

[tex]\boxed{\begin{minipage}{7cm}\underline{Area of a triangle}\\\\$A=\dfrac{x_1(y_2 - y_3) + x_2(y_3 - y_1) + x_3(y_1 - y_2)}{2}$\\\\where:\\ \phantom{ww}$\bullet$ $(x_1,y_1), (x_2,y_2)$ and $(x_3,y_3)$ are \\ \phantom{ww}\;\;\; vertices of the triangle. \\\end{minipage}}[/tex]

From inspection of the given diagram, the vertices of the triangle are:

Substitute the vertices into the formula to solve for area:

[tex]\implies A=\dfrac{4(5 - 9) + 8(9 - 6) + 5(6 - 5)}{2}[/tex]

[tex]\implies A=\dfrac{4(-4) + 8(3) + 5(1)}{2}[/tex]

The last sentence of the proof is Because f+e=c, [tex]a^{2} + b^{2} = c^{2}[/tex]. Hence, option b is the correct answer to this question.

We have that △ABC and △CBD are right-angled triangles.

We have to prove [tex]a^{2} + b^{2} = c^{2}[/tex].

We are given the proof too.

Because △ABC and △CBD both have a right angle, and the same angle B is in both triangles, the triangles must be similar by AA.

Likewise, △ABC and △ACD both have a right angle, and the same angle A is in both triangles, so they also must be similar by AA.

The proportions and are true because they are ratios of corresponding parts of similar triangles. The two proportions can be rewritten as

[tex]a^{2}[/tex] = cf and [tex]b^{2}[/tex] = ce.

Adding [tex]b^{2}[/tex] to both sides of the first equation, [tex]a^{2}[/tex] = cf, which results in the equation [tex]a^{2} + b^{2} = cf +b^{2}[/tex].

Because [tex]b^{2}[/tex] and ce are equal, ce can be substituted into the right side of the equation for [tex]b^{2}[/tex], resulting in the equation [tex]a^{2}+b^{2}[/tex] = cf + ce.

Applying the converse of the distributive property results in the equation  [tex]a^{2}+b^{2}[/tex]= c(f + e).

Now Because f+e=c, [tex]a^{2} + b^{2} = c^{2}[/tex] .

Hence, the last sentence of this proof is Because f+e=c, [tex]a^{2} + b^{2} = c^{2}[/tex].

c. Because [tex]a^{2} + b^{2} = c^{2}[/tex], f + e = c.

d. Because [tex]a^{2} + b^{2} = c^{2}[/tex], f + e = 1.

Because △ABC and △CBD both have a right angle, and the same angle B is in both triangles, the triangles must be similar by AA. Likewise, △ABC and △ACD both have a right angle, and the same angle A is in both triangles, so they also must be similar by AA. The proportions and are true because they are ratios of corresponding parts of similar triangles. The two proportions can be rewritten as a2 = cf and b2 = ce. Adding b2 to both sides of first equation, a2 = cf, results in the equation a2 + b2 = cf + b2. Because b2 and ce are equal, ce can be substituted into the right side of the equation for b2, resulting in the equation a2 + b2 = cf + ce. Applying the converse of the distributive property results in the equation a2 + b2 = c(f + e).

Step-by-step explanation:

$15 = 1.25x + 2.50y

x number of games, y = number of rides

Graphing this will show a line with coordinates (x, y) on it who 'fit' in this equation to make it = 15

I graphed points where both x and y are whole numbers.

These are answers to the equation that make it = 15.

Graph the line 2x = y   (2 times the number of games is the number of rides)

Where the lines intersect is where number of rides is twice taht of games, and the price is 15.

Visually, we can determine that they intersect at (2.4, 4.8)

To verify that this is correct, plug them into the first function to see if this gives you 15.

It does equal 15.

While these are not whole numbers, they do make the equations true, but in the real world we would not have numbers like this.

Parallel slope intercept form is a form of linear equation that describes a line parallel to a given line with slope m.

It is written as y = mx + b, where m is the slope of the line and b is the y-intercept of the line. This form is useful for finding equations of lines that are parallel to a given line.

y = mx + b

y = mx + b is an equation in the form of a straight line, where m is the slope of the line and b is the y-intercept of the line. This form can be used to determine the equation of a line that is parallel to a given line. The equation can be re-arranged to solve for x, if needed.

Step-by-step explanation:

To find the percentage of the blimp that is filled with gas, we need to divide the volume of the gas that is in the blimp by the total volume of the blimp and then multiply the result by 100%.

The blimp is filled with 28,700 cubic feet of gas, and it has a total volume of 35,000 cubic feet when fully expanded, so the percentage of the blimp that is filled with gas is 28,700 / 35,000 = 0.82.

To express this as a percentage, we need to multiply the result by 100%, so the blimp is 82% full.
