Can fractions still be considered natural, whole, integers, rational, irrational, or real numbers?

Answers

Answer 1
Fractions are numbers which can be represented in the form p/q, where p and q are WHOLE NUMBERS and q is not zero Rational numbers are numbers which can be represented in the form p/q where p and q are INTEGERS and q is not zero So your saying " all rational numbers are all numbers that can be represented as a fraction." is wrong....... all fractions are rational numbers but NOT ALL rational numbers are fractions..

Amounts of trade discounts are not fixed? True or False ...?

Answers

True. A trade discount is the amount by which a manufacturer reduces the retail price of a product when it sells to a reseller, rather than to the end customer. The trade discount is determined by quantity and market and is set at a rate by the manufacturer. 

Trade discounts are not fixed; they are true to vary based on several factors including order volume, buyer-seller relationships, and industry norms. They are a dynamic component of economic transactions within the complex trade environment and are influenced by market interactions and broader economic principles.

The statement "Amounts of trade discounts are not fixed" is true. Trade discounts can vary greatly and are typically influenced by a variety of factors including the volume of the goods ordered, the relationship between the buyer and seller, and the industry standards.

For instance, when businesses deliver larger lots, volume discounts may be offered, which reflect the lower costs of providing goods in bulk rather than differences in willingness to pay. This variation in trade discounts ensures that each transaction is adjusted to meet the precise needs of both the buyer and seller, depending on the specific circumstances of the trade.

Moreover, the trade environment is complex and the interactions between buyers and sellers determine the gains from trade in an economy. These interactions depend on market structure, negotiation possibilities, and the mode of sale, such as retail or auction.

Consequently, trade discounts are part of a dynamic economic system where various elements such as free trade agreements, industry adjustments, transaction costs, and the unmeasured benefits of competition and product variety all play a role in shaping the final outcome.

Choose the method of pay that would result in the most earnings for one month on sales of $73,620. a. Straight commission of 6% on all sales. b. Monthly salary of $3,000 plus 2% commission on all sales. c. Graduated commission of 4% on the first $50,000 in sales and 9% on anything over that. d. Graduated commission of 5% on the first $35,000 in sales and 7% on anything over that.

Answers

a. 0.06(73,620) = 4417.20 pay on straight commission of 6%
b. 3000 + 0.02(73,620) = 3000 + 1472.40 = 4472.40 (salary + 2% com)
c. 0.04(50,000) + 0.09(73620 - 50,000) = 2000 + 2125.80 = 4125.80
d. 0.05(35,000) + 0.07(73620 - 35,000) = 1750 + 2703.40 = 4453.40

most earnings would be : B. monthly salary + 2% commission

The method of pay that results in the most earnings is the second method of pay

In order to determine which method of pay would result in the most earnings ,  the value of each method would be determined

Value of the first option

6% commission on all sales = 6% x  $73,620.

0.06 x  $73,620. = $4,417.20

Value of the second option

Monthly salary of $3,000 plus 2% commission on all sales =  $3,000 + (2% x  $73,620)

$3,000 + (0.02% x  $73,620)

= $3000 + $1472.40

= $4472.40

Value of the third option

Graduated commission of 4% on the first $50,000 in sales and 9% on anything over that.

= (4% x $50,000) + (9% x $23,620)

generate the first five terms in the sequence using the explicit formula. yn=-5n-5

Answers

For this you need to note that "n" represents position of sequence.
y1 is y on position 1 and so on. Sequence goes: y1,y2,y3,y4... and so on

So all you have to do is to implement values 1,2,3,4,5 for n and get 5 members of sequence. (start from 0 if your n starts from 0)

y0 = -5
y1 = -5-5 = -10
y2 = -15
y3 = -20
y4 = -25
y5 = -5*5 - 5 = -30

The first five terms in the sequence generated by the explicit formula [tex]y_n[/tex] = -5n - 5 are: -10, -15, -20, -25, -30.

To generate the first five terms in the sequence using the explicit formula [tex]y_n[/tex]  = -5n - 5,

we substitute the values of n from 1 to 5 into the formula.

For n = 1:

[tex]y_1[/tex]= -5(1) - 5 = -10

For n = 2:

[tex]y_2[/tex] = -5(2) - 5 = -15

For n = 3:

[tex]y_3[/tex] = -5(3) - 5 = -20

For n = 4:

which is bigger 40% of 210 or 1/4 of 320

Answers

Final answer:

To find out which is bigger, we calculate 40% of 210 and 1/4 of 320. 40% of 210 is greater than 1/4 of 320.

Explanation:

To find out which is bigger, 40% of 210 or 1/4 of 320, we need to calculate both values.

First, 40% of 210 can be calculated by multiplying 210 by 0.4. This gives us 84.

Next, 1/4 of 320 can be calculated by dividing 320 by 4. This gives us 80.

Therefore, 40% of 210 is greater than 1/4 of 320.

An object with a mass of 6.3 kg has a mass of 7.1newtons applied to it, what is the resulting acceleration of the object

Answers

Since, a = F (net) / m (net)
Therefore a = 7.1 / 6.3 = 1.13 m/sec^2

The resulting acceleration of the object is approximately [tex]\( 1.127 \, \text{m/s}^2 \).[/tex]

To find the resulting acceleration of an object when a force is applied to it, you can use Newton's second law of motion, which states:

F = ma

Given that the force F = 7.1 Newtons and the mass m = 6.3 kg, we can rearrange the formula to solve for acceleration:

[tex]\[ a = \frac{F}{m} \]Substitute the given values:\[ a = \frac{7.1 \, \text{N}}{6.3 \, \text{kg}} \]Now, divide to find the acceleration:\[ a = \frac{7.1}{6.3} \, \text{m/s}^2 \]\[ a = 1.127 \, \text{m/s}^2 \][/tex]

So, the resulting acceleration of the object is approximately [tex]\( 1.127 \, \text{m/s}^2 \).[/tex]

The cost of 5 dresses and 2 belts is $48. The cost of 3 dresses and 2 belts is $32. Find the cost of a dress and a belt. Let x denote the cost of a dress and y denote the cost of a belt.

Answers

For this Question use the substitution method.

5x+2y = $48 ------First Equation.
3x+2y = $32 ------ Second Equation

x= 48-2y/ 5 ( 48-2y divided by 5)

Put the value of x in the second equation.

3(48-2y/5)+2y = $32
 (144-6y/5) + 2y = $32
Take L.C.M 
144-6y+10y/5 = $32
144+4y = 32*5
144+4y = 160
4y = 160-144
4y = 16
y = 4
Now put the value of y in any equation.
5x+2(4) = $48
5x+8 = $48
5x = 48-8
5x = 40
x = 8
-------------------------
A Dress costs $8 and a belt costs $ 4.
Final answer:

By setting up a system of linear equations and solving for x and y, we find that the cost of a dress is $8 and the cost of a belt is $4.

Explanation:

To find the cost of a dress and a belt, we can set up a system of linear equations using the information given. Let x denote the cost of a dress and y denote the cost of a belt. We then have two equations:

5x + 2y = $48  (1)3x + 2y = $32  (2)

Subtract equation (2) from equation (1) to eliminate y:

5x + 2y - (3x + 2y) = $48 - $32

2x = $16

Now we can solve for x:

x = $16 / 2

x = $8

Now that we know the cost of a dress (x), we can substitute this value into equation (2) to find the cost of a belt (y):

3(8) + 2y = $32

24 + 2y = $32

2y = $32 - $24

2y = $8

y = $8 / 2

y = $4

Therefore, the cost of a dress is $8 and the cost of a belt is $4.

Answers

Final answer:

To find the product of (-2x^2)^3 and -3x, first calculate the cube of -2x^2 (-8x^6), then multiply it by -3x to obtain 24x^7.

Explanation:

The student has asked to find the product of two expressions, (-2x^2)^3 and -3x. To solve this, we first calculate the cube of -2x^2, which is -8x^6, then we multiply this result by -3x to find the final product.

So, let's perform these two steps:

Cube of -2x^2: (-2x^2)^3 = (-2)^3 × (x^2)^3 = -8 × x^6 = -8x^6

Multiplication by -3x: -8x^6 × -3x = 24x^7

Therefore, the product is 24x^7.

Final answer:

To solve a quadratic equation using the quadratic formula, put the equation in ax² + bx + c = 0 form, identify a, b, and c, plug them into the formula x = (-b ± √(b² - 4ac)) / (2a), calculate the discriminant, and find the two possible values for x.

Explanation:

To solve a quadratic equation by using the quadratic formula, you should follow these steps:

First, make sure that the equation is in the standard quadratic form, which is ax² + bx + c = 0.Identify the coefficients a, b, and c from the equation.Plug these values into the quadratic formula, which is x = (-b ± √(b² - 4ac)) / (2a).Calculate the discriminant D, which is the part under the square root: b² - 4ac.The discriminant tells you the nature of the roots:
If D is positive, there are two real and distinct solutions.If D is zero, there is one real solution.If D is negative, there are two complex solutions.Finally, calculate the two possible values for x using the plus and minus signs in the formula and simplify as needed.

For example, if we have the equation t² + 10t - 200 = 0, by identifying a=1, b=10, and c=-200, and plugging them into the quadratic formula, we can solve for t.

Write a function Rule that represents the situation: A workers earnings e are a function of the number of hours n worked at a rate of $8.75 per hour

Answers

Final answer:

The function rule representing a worker's earnings e as a function of hours n worked at a rate of $8.75 per hour is e(n) = 8.75 × n. This formula is used to calculate the worker's pay based on their hours worked.

Explanation:

To represent a worker's earnings e as a function of the number of hours n worked at a rate of $8.75 per hour, you would write the function rule as:

e(n) = 8.75 × n

Here, n represents the number of hours worked and e(n) represents the earnings for those hours.

For example, if a worker puts in 8 hours of work, their earnings would be calculated as:

e(8) = 8.75 × 8

      = $70

This means the worker would earn $70 for an 8-hour workday.
