What is the area of the circle? Use 3.14 for

A. 12.6 mm(2)

B. 25.12 mm(2)

C. 50.24 mm(2)

D. 502.4 mm(2)

Answer:  E)1/4y=2x

Step-by-step explanation:

The constant of proportionality represents the ratio between the dependent and independent variables in a proportional relationship. If the constant of proportionality is 1/4, it means that the dependent variable is one-fourth the value of the independent variable.

So, we need to determine which equations have a constant of proportionality of 1/4:

A) y = 4x

The constant of proportionality in this equation is 4, not 1/4.

B) y = 0.25x

The constant of proportionality in this equation is 1/4.

C) 4y = x

The constant of proportionality in this equation is 1/4, since we can rewrite it as y = 1/4x.

D) 32y = 8x

We can simplify this equation by dividing both sides by 8:

4y = x

The constant of proportionality in this equation is 1/4.

E) 1/4y = 2x

We can rewrite this equation as:

y = 8x

The constant of proportionality in this equation is 8, not 1/4.

Therefore, the equations for which the constant of proportionality is 1/4 are B), C), and D).

Answer:

  B, C, D

Step-by-step explanation:

You want to identify the equations that have a constant of proportionality of 1/4.

A proportional relationship can be written in the form ...

  y = kx

where k is the constant of proportionality.

You want to identify those relations that are equivalent to this with k=1/4.

A) y = 4x . . . . . k = 4 ≠ 1/4

B) y = 0.25x . . . . . k = 0.25 = 1/4

C) 4y = x   ⇒   y = 1/4x . . . . . k = 1/4

D) 32y = 8x   ⇒   y = 8/32x = 1/4x . . . . . k = 1/4

E) 1/4y = 2x   ⇒   y = 2/(1/4)x = 8x . . . . . k ≠ 1/4

The relations with a constant of proportionality of 1/4 are B, C , D.

Answer:

A: x

B: 24

C: -15x

D: -14x

Step-by-step explanation:

This is a system of equations problem. The easiest way to find the answers to each of the given blanks is to seek a way to allow for terms within each equation to cancel out when added or subtracted from each other. We can see that within the Y column, they share the least common multiple of 10. In order for the top equation to yield a value of 10y, we must multiply the entirety of it by 2. By doing this we will get x + 10y = 24. Hence, A = x and B = 24. In order to yield a value of | 10y | in the lower equation, we must multiply the entirety of it by -5 (the negative is due to the fact that the value must be -10 in order to cancel out with 10y in the first equation upon adding them together). Once multiplied, we should get -15x - 10y = 200. The subtraction symbol between -15x and 10y can be seen as attached to 10y. These equations combined after multiplication will leave one to be solved for x --> -14x = 224. Therefore, C = -15x and D = -14x.

Answer:

y=⅖x

Step-by-step explanation:

for x=40:

⅖x = ⅖×40 = 16 = y

for x=20:

⅖x = ⅖×20 = 8 = y

for x=10:

⅖x = ⅖×10 = 4 = y

Hence, proved.

Answer: 126 in ^2

Step-by-step explanation:

The surface area of a rectangular prism is given by the formula:

Surface Area = 2lw + 2lh + 2wh

where l, w, and h are the length, width, and height of the rectangular prism, respectively.

Substituting the given values, we get:

Surface Area = 2(3)(5) + 2(3)(6) + 2(5)(6)

Surface Area = 30 + 36 + 60

Surface Area = 126 square inches

Therefore, the surface area of the rectangular prism is 126 in^2.

Answer:

She made $710,000.

Step-by-step explanation:

First, let's multiply how many books she sells per day to the price for each of them. 500x30= 15000, 50x60=3000, 300x80=24000, 400x70=28000, and lastly, 800x800=64000. Next, add up all the numbers to get your total of $710,000!

Step-by-step explanation:

The final coordinates of the triangle after these transformations are (-4, -4), (-4, -1), and (-1, -4).

The triangle was dilated by a scale factor of 1/3, which means that the lengths of each side were divided by 3. The triangle was then reflected over the x-axis, which means that the y-coordinates of each vertex were multiplied by -1. Finally, the triangle was translated left 3 units and up 2 units, which means that 3 was subtracted from each x-coordinate and 2 was added to each y-coordinate. This resulted in the final coordinates of (-4, -4), (-4, -1), and (-1, -4).

Answer: 336.4

Step-by-step explanation: yes

Answer:

See below.

Step-by-step explanation:

For this problem, we are asked to find equivalent expressions.

We should use the Distributive Property.

The Distributive Property is a property that allows us to multiply the number outside of the parentheses into the numbers inside the parentheses. Think of the Distributive Property in the form of x (y + z); We multiply x with y and z.

Since we know what the Distributive Property is, we can begin finding equivalent expressions.

Let's start by distribution:

[tex]3x+3(x+y)\\3x + 3x + 3y\\6x + 3y[/tex]

A is a correct option.

Let's check B and C.

Distribute:

[tex]3(x+x+y)\\3x+3x+3y\\6x+3y[/tex]

B is a correct option.

Distributing isn't needed for expression C.

[tex]3xy\neq 6x + 3y[/tex]

C is an incorrect option.

A and B are the correct options.

Answer: 192.3

Step-by-step explanation:

First, what I would do is add all the whole numbers only.

9 + 100 + 50 + 32 = 191

Next, you would add the decimals like this:

.5 + .1 + .4 + .3 = 1.3

191 + 1.3 = 192.3

Answer:

1/120 or 120

Step-by-step explanation:

Actual monument is 1200 inches tall so that means if we want to find the scale of the model then we do 10/1200 so that = 1/120 or if we are finding the scale factor from the model to the actual then it is 120.
