Answer:

a. $0.07

Step-by-step explanation:

Profit = Charge -Cost

We want to make a profit of 25 and the cost is 10

25 = Charge -10

Add 10 to each side

25+10 = Charge -10+10

35 = Charge

We need to charge 35 per jar.

Each jar contains 500 marbles

The cost per marble is Cost/ number of marbles

cost per marbles = $35 / 500

                             = $.07

Answer:

Option A : $0.07

Step-by-step explanation:

Given :

A school purchases jars of marbles.

Each jar contains 500 pieces of marbles.

Each jar costs $10.

To Find : How much does the school have to charge for each piece of marbles to make a profit of $25 per  jar?

Solution :

Cost of one jar is $10

Now, school wants to make profit of $25 on each jar .

using formula : Profit = Charge - cost

⇒$25 = charge - $10

⇒$35 = charge

Thus school should charge one jar of marbles of $35.

Since each jar contains 500 marbles.

So,to calculate cost of each marble when charge of jar is $35.

Cost of 500 marbles is $35

Cost of 1 marble = 35/500 = $0.07

cost of each marble when charge of jar is $35 is $0.07

Hence , the school have to charge $0.07 for each piece of marble to make a profit of $25 per  jar.

Option A is correct

Answer:

(a) 13

(b) LIFO: $19.60; FIFO: $37.50; Avg: $28.26

Step-by-step explanation:

(a) The starting inventory was 12 sets. Added to that were 4, 6, 6, 10, to make a total of 38 paint sets. 25 were sold, so 13 remained at the end of the year.

(b)

LIFO

Sets purchased at the end of the year are sold first (last-in, first-out). So the sets remaining in inventory are the ones purchased at the beginning of the year. Those 13 sets cost 12@1.50 +1@1.60 = $19.60.

FIFO

Sets purchased first are sold first, so the sets remaining in inventory are the ones purchased last. Those 13 sets cost 10@3.00 +3@2.50 = $37.50.

Avg

The total cost of all inventory purchases was ...

... 12@1.50 +4@1.60 +6@2.20 +6@2.50 +10@3.00

... = 18.00 +6.40 +13.20 +15.00 +30.00 = $82.60

Then the value of the remaining 13 of the 38 items bought is ...

... (13/38)·$82.60 = $28.26.

Answer:

Option b. 30.5

Step-by-step explanation:

Given in the picture is a triangle ABC with sides AB = 22.3 and side BC=24.1

The included angle B = 82 degrees

We have to find the third unknown side AC = b

REcollect the cosine formula for triangles.

[tex]b^{2} =a^{2} +c^{2} -2ac cos B[/tex]

substitute for a and c

We get

[tex]b^2 = 22.3^2+24.1^2-2(22.3)(24.1) cos 82\\=928.587[/tex]

b = square root of 928.587

To write 64x^9 as a square of a monomial, we can write it as (8x^4)^2. To write it as a cube of a monomial, we can write it as (4x^3)^3.

Explanation:

To write 64x^9 as a square of a monomial, we need to find a monomial that, when squared, equals 64x^9. To do this, we need to identify the square root of 64, which is 8, and the square root of x^9, which is x^4. Therefore, 64x^9 can be written as (8x^4)^2.

To write an expression as a cube of a monomial, we need to find a monomial that, when cubed, equals the given expression. In this case, we need to find the cube root of 64, which is 4, and the cube root of x^9, which is x^3. Therefore, 64x^9 can be written as (4x^3)^3.

Answer:

Triangle A prime B prime C prime. is obtained by dilating Triangle ABC. by a scale factor of 1 over 2. and then rotating it about the origin by 180 degrees

Step-by-step explanation:

All the coordinates of A'B'C' are -1/2 times those of ABC. The dilation factor is 1/2, and rotation by 180° is indicated.

A'(-1, -1) = (-1/2) × A(2, 2)

B'(-1, -5) = (-1/2) × B(2, 10)

C'(-4, -6) = (-1/2) × C(8, 12)

Rotation by 180° negates both coordinates. It is equivalent to reflection across the x-axis and reflection across the y-axis, in either order.

Answer:

Step-by-step explanation:

Answer:

The values for both of the missing sides is 8.

Step-by-step explanation:

The hypotenuse of a right triangle = a(square root of 2)

Therefore the other two missing sides equal a.

Therefore, the other two sides equal 8.

now, recalling the pythagorean theorem a little.

the hypotenuse here is 8√2, and then we have the other two sides, BUT, the opposite angle for each is actually the same 45°, if each opposite angle is the same, the length of the side on the other end is also the same.

so we have say side "b" and side "a", but because each has an opposite angle of 45°, that means "b" and "a" are actually twins.

[tex]\bf \textit{using the pythagorean theorem} \\\\ c^2=a^2+b^2\implies (8\sqrt{2})^2=a^2+b^2 \qquad \begin{cases} c=\stackrel{hypotenuse}{8\sqrt{2}}\\ a=adjacent\\ b=opposite\\ \end{cases} \\\\\\ \stackrel{\textit{since we know that \underline{a = b}}}{[8^2(\sqrt{2})^2]=a^2+a^2}\implies 64(2)=2a^2\implies \cfrac{64(2)}{2}=a^2\implies 64=a^2 \\\\\\ \sqrt{64}=a\implies 8=a=b[/tex]

The sequence of translation and dilation of transformation would change two congruent figures into two similar figures that are no longer congruent.

Option B is the correct answer

It is the movement of the shape in the left, right, up, and down directions.

The translated shape will have the same shape and size.

There is a positive value when translated to the right and up.

There is a negative value when translated to the left and down.

We have,

Two congruent figures:

If a translation is applied to the two congruent figures we get the same shape and size.

If we apply a dilation after the translation to the two congruent figures the size of the figures changes.

If translation and dilation are applied to two congruent figures this sequence would change two congruent figures into two similar figures that are no longer congruent.

Answer:

It does. "Proof" below.

Step-by-step explanation:

In order for the given points to lie on the circle, they must both be the same distance from the origin. The Pythagorean theorem is used to make a "distance formula" for computing the distance between two points.

For a point (x, y), its distance (d) to the origin will be ...

... d = √(x² +y²)

For the reference point that we know is on the circle, this distance (the circle's radius) is ...

... d = √(5² +0²) = √25 = 5

For the point in question, the distance to the origin is ...

... d = √((√21)² +2²) = √(21 +4) = √25 = 5

Both points have the same distance to the origin, 5 units, so a circle (of radius 5) centered there will contain both points.

Answer:

Step-by-step explanation:

The table that can be used to determine how long it would take if Elias and Niko polished the silver together is table B

You can create a table to determine the time it would take Elias and Niko together to polish the silver based on their individual rates of completing the task.

Let's denote:

Elias's rate of polishing = 1 job / 40 minutes

Niko's rate of polishing = 1 job / 50 minutes

To find the combined rate when they work together, you can use the formula:

Combined rate = Elias's rate + Niko's rate

Elias's rate = 1 job / 40 minutes

Niko's rate = 1 job / 50 minutes

So, the combined rate when they work together will be:

Combined rate = 1/40 + 1/50

Combined rate = (5/200) + (4/200)

Combined rate = 9/200

Then it goes from 3 to 5, meaning it has an increase of 2 in x, meaning it has to drop down in 12 to be linear, It does. 19-12 is 7.

A parallel line will have the same slope. If there are less-obvious choices to select from, you need to know the slope of the given line. That is computed from ...

Answer:

Step-by-step explanation:

6x – 3(0) = 24?

6x = 24

6x / 6 = 24 / 6

x = 4

x-intercept = (4, 0)

The x-intercept of the line 6x - 3y = 24 is (4, 0).

The x-intercept of a line represents the point where the line intersects the x-axis. To find the x-intercept of the line 6x - 3y = 24, we need to set y = 0 and solve for x.

Substituting y = 0 into the equation, we get 6x - 3(0) = 24. Simplifying this equation gives us 6x = 24, and dividing both sides by 6 gives x = 4.

Therefore, the x-intercept of the line 6x - 3y = 24 is (4, 0).
