If Natasha is taking out a three week payday loan for $400. He will be charged with $70 interest for a 3 week loan. the APR (annual percentage rate) is $304.2

Using this formula to determine the annual percentage rate
APR = [(( interest/principal)/number  of days )×365]×100

Principal = $400

Interest = $70

Number of days = 3 weeks = 21 days

Let plug in the formula

APR  = [(( 70 / 400)/ 21) ×365 ] ×100

APR  = 0.008333 x 365 × 100

APR =  304.166

APR = 304 .2 (Approximately)

The product expression (5ab) x (- 2a²b)³ has a value of -40a⁷b⁴, when evaluated

The expressions are given as

(5ab) and (- 2a^2 b)^3

This means that

The product expression is the product of (5ab) and (- 2a²b)³

Rewrite the expression as:

(5ab) x (- 2a²b)³

Open the brackets in the above expression

So, we have

(5ab) x (- 2a²b)³ =  5ab x (-2)³ x (a²)³ * (b)³

Evaluate the exponents

So, we have

(5ab) x (- 2a²b)³ =  5ab x (-8) x a⁶ * b³

Evaluate the products of the variables

This gives

(5ab) x (- 2a²b)³ =  5a⁷b⁴ x (-8)

Evaluate the other products

This gives

(5ab) x (- 2a²b)³ =  -40a⁷b⁴

Hence, the value of the product expression is -40a⁷b⁴

Time take to read a book that has 218 pages is  196.2

According to the question, given that

Time takes to read 5 pages of a book can be represented equation y equal to 4.5  divided by 5 times

where y represents the total time in minutes and x represents the number of pages read

Time take to read a book that has 218 pages.

x = [tex]218*\frac{4.5}{5}[/tex]

  = [tex]\frac{981}{5}[/tex]

  = 196.2

Therefore, we get time 196.2 to read a book that has 218 pages.

Depending on which values you input into the reading time , you can find out:

- How much time per day should you allocate to finish in x days;

Using proportions, it is found that:

a) Jana runs faster, due to the higher velocity.

b) Jana's speed is of 47,520 feet per hour.

c) Jana's speed is of 792 feet per minute.

A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using relations with operations such as multiplication and division.

One example of the application of proportions in this problem is for the relation between velocity, distance and time, as velocity is distance divided by time, that is:

v = d/t.

Hence the velocities in this problem are given as follows:

Due to the higher velocity, Jana runs faster.

Another application of proportions is for conversion of units. Each mile has 5280 feet, hence Jana's speed in feet per hour is given by:

9 x 5280 = 47,520 feet per hour.

Each hour has 60 minutes, hence Jana's speed in feet per minute is given by:

47520/60 = 792 feet per minute.

According to the concept of scales, the scale length of the scale model of the 1940 Ford pickup truck is 10.5 inches.

Scale models are useful resource to describe huge and tiny system at a reasonable scale, whose dimensions are derived from the concept of scale, which relates scale lengths to real lengths in the following manner:

d' = r · d

Where:

If we know that d = 15.75 ft and r = 2 / 3 in / ft, then the scale length of the 1940 Ford pickup truck is:

d' = (2 / 3 in / ft) · (15.75 ft)

Annabelle did not make a mistake. you have to substitute 0 in for x then dived the equation by 2 giving you the answer of 4. She is correct. A rockstar as the answer says. :) hope this helped!

======================================================

Reason:

She wants to find the y value when x = 0. This is why she replaced every copy of x with 0. Step 1 is correct.

Step 2 is also correct because 3 times 0 is 0. She multiplied correctly.

Step 3 is correct because she needs to undo the "2 times" that is applied to y, in order to isolate it. Division is the inverse operation of multiplication.

Step 4 is correct because 8/2 is 4

Every step she did is correct, and so is the final answer.

------------

Here's one way Annabelle could check her work

3x+2y = 8

3*0+2*4 = 8 .... plug in x = 0 and y = 4

0 + 8 = 8

8 = 8

We get the same thing on both sides, which confirms that x = 0 pairs up with y = 4. In other words, (x,y) = (0,4) is a solution to 3x+2y = 8.

The point (0,4) is on the line 3x+2y = 8. This point is the y intercept where the graph crosses the y axis.

What are the conditions for a quadratic equation not to have real roots?
A quadratic function has no actual roots and the parabola it represents does not intersect the x-axis if its discriminant is less than zero.
What is the discriminant of a quadratic equation?
A polynomial's discriminant is a function of its coefficients and is denoted by a capital "D" or the symbol for the delta (Δ). In any quadratic equation where a, b, and c are rational numbers, it demonstrates the nature of the roots. With a quadratic equation, the real roots or the number of x-intercepts are easily demonstrated. This equation is used to determine if the quadratic equation's roots are real or imaginary.
For a quadratic equation as ax² + bx + c = 0, the discriminant is
Δ = b² - 4ac

Given, the quadratic equation is 2x² + (-3)x + (-1 - k) = 0
Comparing this to the standard form of quadratic equation, the value of the discriminant is: Δ = b² - 4ac = (-3)² - 4(2)(-1 -k) = 9 + 8(k + 1) = 17 + 8k
Following the condition established in the literature above, Δ<0
Therefore, 17 + 8k < 0 ⇒ 17 < -8k ⇒ k > (-17/8)
Thus, the set of possible values of k is (-17/8, ∞)

                             [tex]\sf = -1\dfrac{31}{33}[/tex]              

Answer: -64/33 or -1 31/33

Step-by-step explanation:

First, whenever you are dividing mixed fractions we always convert them to an improper fraction, so let’s do that first.

We multiply the whole number to the denominator and then add that number to the numerator.
-5 1/3

This would be (-5*3) + -1(note that since it’s a negative number, we would have to subtract this

= -16, and add the original denominator 3 also, so it’s -16/3

Do the same for 2 3/4

(2*4) + 3 = 11

11/4

(-16/3) / (11/4)

Now to convert this expression into multiplication, we use the reciprocal(flipped version) of the divisor

11/4 would become 4/11

Which makes the expression:

(-16/3) * (4/11)

Now just multiply the denominators with each other and the numerators

-16*4 = -64

3*11 = 33

Your answer would be -64/33 or in mixed fraction form, -1 31/33

Simple interest is the interest calculated on the principal at a given rate for a time period.

The equation used to solve for the rate of interest r is r = (A/P - 1) / t.

It is the interest calculated on the principal at a given rate for a time period.

We have,

A = P + Prt ______(1)

A = amount

P = principal

r = rate

t = time in years

To find the rate of interest we will have to solve (1).

A = P + Prt

A = P (1 + rt)

A/P = 1 + rt

Subtract 1 on both sides.

A/P - 1 = rt

Divide t on both sides.

(A/P - 1) / t = r

r = (A/P - 1) / t

Thus,

The equation used to solve for the rate of interest r is r = (A/P - 1) / t.
