Answer:

15 lbs of onions.

Step-by-step explanation:

23 lbs divided by $46 = 0.5 lbs per $1

0.5 lbs times $30

15 lbs

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

Work Shown:

(23 pounds)/(46 dollars) = (x pounds)/(30 dollars)

23/46 = x/30

1/2 = x/30

1*30 = 2*x

30 = 2x

2x = 30

x = 30/2

x = 15

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

Another approach:

Divide the cost over the number of pounds to find the unit price

46/23 = 2

The onions cost $2 per pound.

If x is the number of pounds, and we pay $30, then

2x = 30

x = 30/2

x = 15

Meaning 15 pounds of onions cost $30.

Answer:

x = 8

[tex]\overline{AC}[/tex] = 30

[tex]\overline{CD}[/tex] = 10

Step-by-step explanation:

Triangle [tex]\triangle ABC[/tex] and triangle [tex]\triangle DEC[/tex] are similar because they have 2 congruent angles. We can find the scale factor between them by comparing the length of [tex]\overline{BC}[/tex] and  [tex]\overline{EC}[/tex] in a fraction, resulting in us finding the scale is 3:1 from [tex]\triangle ABC[/tex] to [tex]\triangle DEC[/tex].

Now we can solve for x using a proportion.

[tex]\frac{3}{1} = \frac{x+22}{x+2}[/tex] | Cross multiply

3x+6 = x+22 | Subtract x from both sides

2x+6 = 22 | Subtract 6 from both sides

2x = 16 | Divide both sides by 2

x = 8

Now we can solve for [tex]\overline{AC}[/tex] and [tex]\overline{CD}[/tex] by substitution.

[tex]\overline{AC}[/tex] = x + 22 = 8 + 22 = 30

[tex]\overline{CD}[/tex] = x + 2 = 8 + 2 = 10

These are your answers

If the width and length of the rectangle are 3 cm and 7 cm. Then the perimeter of the rectangle is 10 cm.

It is a polygon with four sides. The total interior angle is 360 degrees. A rectangle's opposite sides are parallel and equal, and each angle is 90 degrees. Its diagonals are all the same length and intersect in the center.

Let L be the length of the rectangle and W be the width of the rectangle.

Then we have

4W + 3L = 33 ...1

 2W + L = 13 ...2

Then by the equations 1 and 2, we have

W = 3 and L = 7

Then the perimeter of the rectangle will be

Perimeter = W + L

Perimeter = 3 + 7

Perimeter = 10 cm

Answer:

153.86 in²

Step-by-step explanation:

The area of a circle is:

A = π r²

Radius is just half of the diameter so r = 7.

Substitute 3.14 for π.

Restate the equation:

A = 3.14 x 7² = 3.14 x 49

A = 153.86

If the radius of the semi-circle is 38 m. Then the area of the training field will be 11,908.459 square meters.

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

A training field is formed by joining a rectangle and two semicircles, as shown below. The rectangle is 97 m long and 76 m wide.

Then the radius of the semi-circle will be

2r = 76

 r = 38 m

Then the area of the training field will be

Area = area of rectangle + 2 x area of semi-circle

Area = 97 x 76 + 2 x (1/2) x π x 38²

Area = 7372 + 4536.459

Area = 11908.459 square m

Answer:

60

Step-by-step explanation:

The evaluated expression of 3x² + 4y⁰(x - 1) when x = 4 and y = 5 is  60.

What is Substitution?

Substitution simply means to put in place another. Therefore, let's substitute the value of x and y in the mathematical expression.

3x² + 4y⁰(x - 1)

Therefore,

y⁰ = 1

3x² + 4y⁰(x - 1)

3x² + 4y⁰(x - 1)

3x² + 4(x - 1)

3x² + 4x - 4

Therefore, when x = 4 and y = 5

3(4)² + 4(4) - 4

48 + 16 - 4 = 60

Step-by-step explanation:

Notice that the graph of the parabola opens downward. This tells us that the leading coefficient of the function must be negative. Hence, we can rule out answers A and D.

Also, notice that our vertex is [tex](h,k)\rightarrow(-1,2)[/tex], which when we plug into vertex form, we get [tex]y=a(x-h)^2+k\rightarrow y=a(x-(-1))^2+2\rightarrow y=a(x+1)^2+2[/tex].

Answer:

396 = 341q-333

Step-by-step explanation:

396 is (396 =)

the quantity q times 341 (341q)

333 subtracted from (-333)

Answer:

341q - 333 = 396

Step-by-step explanation:

multiply q and 341, you get 341q

a number that is subtracted from another number is the same as saying 2 is subtracted from 5 gives you 3, which can be laid out as 5 - 2 = 3

therefore your equation will be 341q - 333 = 396

extra information :

341q = 396 + 333

341q = 729

q = 729/341

q = 2.137829912

Therefore the percentage difference in profit realized will be 66.67 % .

Profit, is net income earned after subtracting all dollar costs from total revenue.

In effect, it shows the amount of money a firm has left over after deducting the explicit costs of running the business.

Suppose all the charges for making the shoes is x (other than the labour charge)

Labor charge in Asia is y

And as given in the question Labor Charge in United States is 5y

The final cost off the shoes is $65

Profit in asia = (65-x-y)

Profit in United States = (65-x-5y)

Let's use trial and error method to understand this

suppose the making cost is x = $10  and the labor charge in asia is $5 per shoes so

Profit in Asia = 65-10-5 = $50

Profit in United Stated = 65- 10-25 = $30

the percentage difference in profit realized

= (50-30) * 100 /30

= 2000/30 = 200/3 = 66.67%

Therefore the percentage difference in profit realized will be 66.67 % .
