A retailer’s gross margin on a $150 item is $40. Calculate GMC as a percentage.

Answers

The gross margin cost for the case when the considered retailer’s gross margin on a $150 item is $40 is 26.67% approximately.

How to find how much percent 'a' is of 'b'?Suppose a number is 'a'Suppose another number is 'b'

We want to know how much percent of 'b' is 'a'.

Then, it is calculated as:

[tex]\dfrac{a}{b} \times 100[/tex]

(in percentage)

Given that:

The cost of the considered item = $150The gross margin of retailer on that item = $40

Here we assume that the term GMC is referring to gross margin cost.

Let this gross margin cost (GMC) $40 be P% of the original cost of the item $150.

Then, we get:

[tex]p = \dfrac{40}{150} \times 100 \approx 26.67 \text{(in percentage)}[/tex]

Thus, the gross margin cost for the case when the considered retailer’s gross margin on a $150 item is $40 is 26.67% approximately.

WHICH ONE IS CORRECT?

Two cubes have edge lengths of 9 cm and 3 cm, respectively. What is the difference in volume of the two cubes?

1. 243 cm3

2. 756 cm3

3. 27 cm3

4. 702 cm3

Answers

The difference in volume of the two cubes is 702 cm3

Step-by-step explanation :

Given-

Length of edge of one cube = 9 cmLength of edge of second cube = 3 cm

Now, The formula for finding volume of any cube is -

[tex] \underline{ \boxed{ \mathfrak \red{volume \: of \: cube = {edge}^{3} }}}[/tex]

Therefore, substituting values. . .

Volume of one cube = [tex] {(9)}^{3} [/tex]

[tex] \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:\: \: \: \: \: \: \: \: \: \: \:\: \: \: \: \: \: \: \: \: \: \: \: = 9 \times 9 \times 9[/tex]

[tex] \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:\: \: \: \: \: \: \: \: \:\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 729 \: {cm}^{3} [/tex]

Similarly,

Volume of second cube [tex] = {(3)}^{3} [/tex]

[tex] \: \: \: \: \: \: \:\: \: \: \:\: \: \: \: \: \: \: \: \: \:\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:\: \:\: \: \: \: \: \: = 3 \times 3 \times 3[/tex]

[tex] \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:\: \: \: \: \: \: \: \: \: \: \: \:\: \: \: \:\: \: = 27 \: {cm}^{3} [/tex]

Now,

Difference in volume of two cubes = Volume of 1st cube - Volume of 2nd cube

[tex] \: \: \: \: \: \: \: \: \: \:\: \: \: \: \: \: \: \: \: \: \:\: \: \: \: \: \: \: \: \: \: \: \:= (729 - 27) {cm}^{3} [/tex]

[tex] \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 702 \: {cm}^{3} [/tex]

Thus, the difference in volume of the two cubes comes out 702 cm3

Elimination

Substitution

Elimination

Explanations are given below

Step-by-step explanation:

Hello!

1) Substitution

This is because you already have a solution for a variable, y, and you can simply plug in the value of y for the second equation

2) Substitution

The same thing as above, you already have the value of y, and you can simply plug it into the second equation.

3) Elimination

You should use elimination because you can simply eliminate the variable y by adding the two equations, as they have the same coefficient of 3.

4) Elimination

Same as above, simply add the two equations to eliminate x, because they have the same coefficients of 7.

5) Substitution

You have the value for y, so simply plug it into the other equation to solve for x.

6) Elimination

You have -2x in both equations, and subtracting the equations will eliminate the variable x, and you can then solve for y.

If u give answer ill give 100 points NOT FAKE PLS I NEED HELP

Answers

Answer:

86 Degrees

Step-by-step explanation:

First we need to apply the defenition of a Supplementary Angle: A supplrementary angle means an angle whos measure is 180degrees.

As we are given two angles labled supplementary we must know that angleA + angleB = 180degrees.

Now we are given two equations for the measure of each angle.

measure of A = 6x+10

measure of B = 4x+30

We simply plug this into the first equation I've stated above.

6x+10 + 4x+30 = 180

Simplify

10x+40 = 180
10x = 140
x = 14

Now that we have X, we plug this into the measure B equation to get the measure.

4x + 30
(Plug 14)
4(14) + 30

56 + 30

86 Degrees

How to interpret the histogram?

From the histogram (see attachment), we have the following highlights:

The x-axis represents the number of monthsThe y-axis represents the time spent by the employees

Using the above highlights, we can see that:

When x = 30 - 35, the value of y is

Hence, the true statement about the histogram is (a) 5 employees have been in their current position for 30 to 35 months

Answers

Answer: D

Step-by-step explanation:

The domain of a function is the allowed 'x' values that the function can take on and produce a defined 'y' value. We can ignore the numerator since it will never be undefined. The denominator on the other hand has a singularity when it equals zero. The reason for this is because we cannot divide by zero. Therefore, lets set the denominator to zero and find which 'x' value makes the function undefined:

[tex]3x+15=0[/tex]

[tex]3x=-15[/tex]

[tex]x=-5[/tex]

Every single real 'x' value will work besides when x = -5. Therefore the answer is D

Tory and Emilio's motorboats travel at the same speed. Tory pilots her boat 30 km before docking. Emilio continues for another 2 hr, traveling a total of 80 km before docking. How long did it take Tory to navigate the 30 km?

Answers

Answer:

1.2 hours

Step-by-step explanation:

first im going to assume both travel at a constant speed the entire time

both motorboats travel 30 km, so emilio travels another 50 (80-30 = 50) km in 2 hours. speed = distance/time so the speed of the motorboats is 50/2 or 25km/h

divide 30 by 25 to get 1.2hours
