Answer:

Scaling is used to resize the dimension of a structure to fit the different platforms, like from structure to paper.

Step-by-step explanation:

To resize down-scale the dimension of a room, if the scale is 1/4 inches per foot, then the size of a 6x4 feet (width and length) room would be;

1/4 x 6 = 1.5 inches

1/4 x 4 = 1 inches

that is, 1.5 x 1 inch on paper when scaled down.

to figure out this equation, all you need to do is combine like terms!

x = 1x

4x = 4x

6x = 6x

1x + 4x + 6x = 11x

Hope this helped! :D

Answer:

11x is the answer

Answer:

[tex]Boxes= 198[/tex]

Step-by-step explanation:

This question has uncleared details towards the end. However, one can deduce that we need to calculate the amount of box the available space can contain.

We have the following given parameters.

Shipping Container

[tex]Dimension: 2ft\ by\ 3ft\ by\ 33ft[/tex]

The box

[tex]Dimension: 1ft\ by\ 1ft\ by\ 1ft[/tex]

First, we calculate the volume of the shipping container.

[tex]V_A = 2ft * 3ft * 33ft[/tex]

[tex]V_A = 198ft^3[/tex]

Next, we calculate the volume of the box.

[tex]V_B = 1ft * 1ft * 1ft[/tex]

[tex]V_B = 1ft^3[/tex]

The number of box is then calculated as:

[tex]Boxes= \frac{V_A}{V_B}[/tex]

[tex]Boxes= \frac{198ft^3}{1ft^3}[/tex]

[tex]Boxes= \frac{198}{1}[/tex]

[tex]Boxes= 198[/tex]

Hence:

198 boxes will occupy the empty space

Answer:

The value of c that will result in a perfect square trinomial is (3)^2 or 9

The perfect square trinomial is: [tex](w+3)^2=139[/tex]

Step-by-step explanation:

We need to determine the value  of c that will result in a perfect square trinomial.

[tex]w^2+6w+ c =130+c[/tex]

Perfect square trinomial are of form: [tex]a^2+2ab+b^2=(a+b)^2[/tex]

Now, the equation given is:

[tex]w^2+6w+ c =130+c[/tex]

Looking at the term 6w, we can write it as 2(w)(3)

We are given: a = w, 2ab = 2(w)(3) so, b will be: (3)^2

So, we will be adding (3)^2 on both sides

[tex]w^2+6w+ c=130+c\\w^2+2(w)(3)+ (3)^2 =130+(3)^2\\The\:left\:side\:becomes: a^2+2ab+b^2\\We\:can\:write\:it\:as: (a+b)^2\\We\:have\:a=w\: and\: b=3\\(w+3)^2=130+9\\(w+3)^2=139[/tex]

So, The value of c that will result in a perfect square trinomial is (3)^2 or 9

The perfect square trinomial is: [tex](w+3)^2=139[/tex]

Answer:

[tex]R' = (-1,-0.5)[/tex]

Step-by-step explanation:

See attachment for complete question.

From the attachment:

[tex]P = (-3,-3)[/tex]

[tex]R = (1,2)[/tex]

Dilation:

[tex]D_{(0.5,P)}[/tex]

Required

Determine R'

First, subtract the coordinates of P from R. This means that R is measured from P.

[tex]R = (1-(-3),2-(-3))[/tex]

[tex]R = (1+3,2+3)[/tex]

[tex]R = (4,5)[/tex]

Next, apply dilation factor 0.5

[tex]R' = R * 0.5[/tex]

[tex]R' = (4,5) * 0.5[/tex]

[tex]R' = (4* 0.5,5* 0.5)[/tex]

[tex]R' = (2,2.5)[/tex]

Lastly, measure R' from the origin by adding the coordinates of P to R'

[tex]R' = (2+(-3),2.5+(-3))[/tex]

[tex]R' = (2-3,2.5-3)[/tex]

[tex]R' = (-1,-0.5)[/tex]

Dilation of a figure or image is to enlarge or shorter it from the original length by a scale factor.

The coordinate of the R' after the dilation is (-1,-0.5)

Dilation of a figure or image is to enlarge or shorter it from the original length by a scale factor.

Given information-

The points of PQRS are Q(-3,2), R(1,2), P(-3,-3), S(1,-3).

The given points are dilated. This dilation can be measured by subtracting the point P from each point . Thus the point of Q is,

[tex]Q'=Q-P\\Q'=(-3-(-3), 2-(-3))\\Q'=(0,5)[/tex]

Similarly,

[tex]R'=R-P= (1-(-3),2-(-3))=(4,5)\\P'=P-P=(-3-(-3), 3-(-3)=(0,0)\\S'=S-P=(1-(-3),-3-(-3))=(4,0)\\[/tex]

As the dilation factor is 0.5. Thus, the point of Q is,

[tex]Q"=(0.5)\times(0,5)=(0,2.5)[/tex]

Similarly,

[tex]R"=(0.5)\times(4,5)=(2,2.5)\\P"=(0.5)\times(0,0)=(0,0)\\S"=(0.5)\times(4,0)=(2,0)\\[/tex]

Add the points P back, to the above coordinate plane to get the dilation point. Thus the point of Q is,

[tex]Q'''=(0,+(-3), 2.5+(-3))\\Q'''=(-3,-0.5)[/tex]

Similarly,

[tex]R'''=(2+(-3),2.5+(-3))=(-1,-0.5)\\P'''=(0+(-3),0+(-3))=(-3,-3)\\S'''=(2+(-3),0+(-3))=(-1,-3)\\[/tex]

Thus the coordinate of the R' after the dilation is (-1,-0.5)

Answer:

what is the rest of the qustion

Step-by-step explanation:

Answer:Since -2 can not equal 0, there is no solution. The lines are parallel. It is an inconsistent system.

Step-by-step explanation:

The first step in solving a system of equations by substitution is solving one of the equations for one of the variables

x - y = 0 Equation 1

x - y + y = 0 +y Add y to each side

x = y Simplify

After solving an equation for one of the variables, substitute that value into the other equation. In this problem, I can substitute y for x.

x - y - 2 = 0 Equation 2

y - y - 2 = 0 Substitute the value of x from equation 1

0 - 2 = 0 Inverse Property of addition

-2 = 0 Identity Property of addition

Step(i):-

Given that Bob tested 24 bolts that he randomly picked and found that 5 were defective

The proportion of the defective item
