True value received an invoice dated may 08, 2020. the invoice had a $5,800 balance that included $800 freight true value pays the invoice on may 22.  then true value pay amount is $4900

Invoice dated 08/may/2020. Amounting to $5,800 which includes $800 freight.

Terms:

3/10 ; 2/30 ; n/60

The term 3/10 means that True value can avail of 3% discount if it pays within 10 days from date of issuance. The 10th day would be 18/may/2020

The term 2/30 means that True value can avail of 2% discount if it pays from the 11th day up to the 30th day from the date of issuance.

may 22 is beyond the 10th day but within the 30 days discount period. True Value can avail of the 2% discount.

5,800 - 800 = 5,000  The freight can't be subjected to discount thus it is deducted from the total invoice amount.

5,000 * 2% = 100

5,000 - 100 = 4900 amount True Value has to pay.

If the balance were growing according to the exponential function, the balance owed on your credit card after 9 months is equal to $1,502.02.

In Mathematics, an exponential function simply refers to a mathematical function whose values are generated by a constant that is raised to the power of an argument.

From the information provided, an exponential function that models or represents the rate at which the balance owed on your credit card triples is given by:

f(x) = 500(1 + 0.13)^x

Where:

After 9 months, the balance owed on your credit card would be calculated by substituting the value of x with 9 as follows:

Balance owed,  f(x) = 500(1 + 0.13)^9

Balance owed, f(x) = 500(1.13)^9

Balance owed, f(x) = 500 × 3.0040419380

Balance owed, f(x) = $1,502.02.

Using Venn diagram, if a student is chosen randomly, (a) the probability that he or she is not in any of the language classes is 0.5, (b) the probability that he or she is taking exactly one language class is 0.32, and (c) if 2 students are chosen randomly, the probability that at least 1 is taking a language class is 0.753.

Venn diagram is a diagram used to present the relationship between sets in a logical form. (See attached image)

Let A = students in the Spanish class = 28

B = students in the French class = 26

C = students in the German class = 16

Hence, the probability of each class is:

P(A) = 28/100 = 0.28

P(B) = 26/100 = 0.26

P(C) = 16/100 = 0.16

P(A ∩ B) = 12/100 = 0.12

P(B ∩ C) = 6/100 = 0.06

P(A ∩ C) = 4/100 = 0.04

P(A ∩ B ∩ C) = 2/100 = 0.02

(a) P(not A, B, C) = 1 - P(A ∪ B ∪ C)

P(not A, B, C) = 1 - [P(A) + P(B) + P(C) - P(A ∩ B) - P(B ∩ C) - P(A ∩ C) + P(A ∩ B ∩ C)]

P(not A, B, C) = 1 - (0.28 + 0.26 + 0.16 - 0.12 - 0.06 - 0.04 + 0.02)

P(not A, B, C) = 1 - 0.5

P(not A, B, C) = 0.5

(b) P(A, B, C only) = P(A only) + P(B only) + P(c only)

P(A, B, C only) = [P(A) - P(A ∩ B) - P(A ∩ C) + P(A ∩ B ∩ C)] + [P(B) - P(A ∩ B) - P(B ∩ C) + P(A ∩ B ∩ C)] + [P(C) - P(B ∩ C) - P(A ∩ C) + P(A ∩ B ∩ C)]

P(A, B, C only) = (0.28 - 0.12 - 0.04 + 0.02) + (0.26 - 0.12 - 0.06 + 0.02) + (0.16 - 0.06 - 0.04 + 0.02)

P(A, B, C only) = 0.14 + 0.10 + 0.08

P(A, B, C only) = 0.32

(c) P = 1 - (50/100 x 49/99)

P = 1 - (49/198)

P = 149/198

P = 0.753

To complete the problem, here are the questions:

(a) If a student is chosen randomly, what is the probability that he or she is not in any of the language classes?

(b) If a student is chosen randomly, what is the probability that he or she is taking exactly one language class?

(c) If 2 students are chosen randomly, what is the probability that at least 1 is taking a language class?

Step-by-step explanation:

The distance of art store from Ella's house is  2/3 miles or 0.67 miles.

It is a question of time, speed and distance.

It is given in the question that Ella walks to the art store at 2mph, but returns home at 4 mph.

Also, the total time taken by Ella to cover the journey is 1/2 an hour.

We have to find the distance of art store from Ella's house.

Let the distance from Ella's house to art store be d miles.

We know that,

Speed = distance/time

Time = distance/speed

Hence, we can write,

time = d/2  (walking to the art store from from)

Also,

time = d/4  (walking to home from the art store)

Hence,

d/2 + d/4 = 1/2

3d/4 = 1/2

d = 2/3 miles or 0.67 miles.

Answer:

y=1.34x-3.22

Step-by-step explanation:

y=mx+b

find m/ gradient:

[tex]m = \frac{-3.94 - 2.4}{-4.75 - 0}[/tex]

∴[tex]m=1.34[/tex]

find b/ y-intercept:

sub (2.4,0)

0= 1.34 (2.4) +b

b=0-3.216

b= -3.216

∴ b=-3.22(2.d.p)

linear equation:

∴1.34x-3.22

The matchings are:

3x - y = -5 ⇒ table C.

x - 3y = 12 ⇒ table A.

3x - y = -2 ⇒ table D.

2x - 3y = 9 ⇒ table B.

The first equation we have is:

3x - y = -5

Evaluating in x = 0, we have:

3*0 - y = - 5

y = 5

So we have the point (0, 5).

Evaluating in x = -2 we get:

3*-2 - y = -5

6 + y = 5

y = 5 - 6 = -1

So we have the point (-2, -1)

The only table with that point is table C, so we conclude that it is the correct option.

2) The second equation is:

x - 3y = 12

Evaluating in x = 0 we get:

0 - 3y = 12

y = 12/-3 = -4

So we have the point (0, -4)

if x = 3 we have:

3 - 3*y = 12

-3*y = 12 - 3 = 9

y = 9/-3 = -3

So we have the point (3, -3)

The only table with these two points is table A, so that is the correct one.

3) The next equation is:

3x - y = -2

The tables left are B and D.

Now, let's evalaute this equation in x = 3.

3*3 - y = -2

9 - y = -2

9 + 2 = y

11 = y

So we have the point (3, 11)

Notice that on table B,the value associated to x = 3 is y = -1, so we discard table B, and we conclude that this equation relates to table D.

Trivially, the last equation:

2x - 3y = 9

Matches table B.

Mang Efren's present age is 30 years.

Let's assume the present age of Mang Efren's son is x years.

Mang Efren is presently 5 times as old as his son.

So, Mang Efren's present age = 5x years

Four years ago,

Mang Efren's son's age = x - 4 years.

Mang Efren's age = 5x - 4 years

According to the question, four years ago, the product of their ages was 52.

From this information, we will create an equation.

(x - 4)(5x - 4) = 52

5x² - 4x - 20x + 16 = 52

5x² - 24x + 16 - 52 = 0

5x² - 24x - 36 = 0

Solving the quadratic equation to obtain the value of x,

5x² - 30x + 6x - 36 = 0

5x(x -6) + 6(x - 6) = 0

(5x - 6)(x - 6) = 0

x = 6

So, Mang Efren's present age is 5 × 6 = 30 years.

In the picture there is a prism with measures. The surface area of prism is 156.

Given that,

In the picture there is a prism with measures.

We have to find the surface area of prism.

The surface area of prism=(2×base area)+(Base perimeter×height)

The base is trapezoid

So, the area of trapezoid is (a+b)/2×h

=(6+12)/2×4

=18/2×4

=9×4

=36

Here base area we got is 36.

Now, we find the perimeter of trapezoid is a+b+c+d

=6+12+5+5

=18+10

=28

Here, base perimeter we got is 28.

Now surface area of prism is

=(2×36)+(28×3)

=72+84

=156

Therefore, the surface area of prism is 156.

Based on the fact that the two numbers multiply to 2,400 and add up to -16, the numbers are undefined.

Assume that one of the numbers is x and the other number is y, the system of equations to represent this is given that the two numbers add up to -16 and multiplying to 2,400:
x + y = -16

xy = 2,400

Expressing y in terms of x :

xy = 2,400

y = 2,400 / x

Solving for x gives:

x + y = -16

x + (2,400 / x) = -16

x = 0

Clay and Jason are 600 feet far apart.

When an object goes above the surface, the altitude is measured as +ve and when an object goes below the surface, the altitude is measured as -ve.

Since Clay is flying a helicopter at an altitude of 400 feet in the air,

The Value of altitude of Clay = +400

Since, Jason is diving 200 feet below the surface,

The Value of altitude of Jason = -200

The the distance between Clay and Jason = (The Value of altitude of Clay) - (The Value of altitude of Jason)

= +400 - (-200)

For the quadratic equation:

The two solutions are:

x = 4

x = -3

I'm only solving the first question, as it is how the guidelines say.

Here we have the quadratic equation:

x^2 + 7x = 8x + 12

First, we can rewrite this equation as:

x^2 + 7x - 8x - 12 = 0

x^2 - x - 12 = 0.

Using Quadratic formula we can see that the solutions (or zeros of the quadratic) are:

x = (1 ± √(  (-1)^2 - 4*1*-12))/(2*1)

x = (1 ± 7)/2
