Dexter makes a scale drawing of his room. In real life, the room is 10 feet wide and 12 feet and 6 inches long. In Dexter's drawing, the room is 4 inches wide. What measure should the length be?

Answers

Answer 1

Answer:

The length of modeled drawing room is 5 inches.

Given that, the room is 10 feet wide and 12 feet and 6 inches long.

What is scale factor?

A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller).

The basic formula to find the scale factor of a figure is expressed as,

Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape.

So, scale factor = 4 inches

We know that, 1 feet = 12 inches

Now, scale factor = 4/(10×12)

= 4/120

= 1/30

Length = 1/30 ×(12 feet and 6 inches)

= 1/30 × (144+6)

= 1/30 × 150

= 5 inches

Therefore, the length of modeled drawing room is 5 inches.

How do you express 43.7% as a decimal?

Answers

43.7 % is equivalent to 0.437 .

you move the decimal 2 spaces to the left and drop the percentage sign. a cool trick is to count when you do it. move the decimal once say "tens" then move it twice say "hundreds" same goes for thousands and so on. your answer should look like this .437
or if rounded .44

Sam rotated parallelogram ABCD 90° clockwise around the origin. If angle A is 130° and angle B is 50°, what is the degree measurement of angle A'?

Answers

Answer-

The measurement of angle A' will be 130° .

Solution-

Transformations like - rotations, reflections, and translations are isometric. That means that these transformations do not change the size of the figure. If the size and shape of the figure is not changed, then the figures are congruent.

It doesn't matter the order or how much degree of rotation has taken place, the final image will be congruent to the original image.

So, even after the rotation of 90° clockwise around the origin, the measurement of angle A will be 130° and so do all the rest of the angles.

Answer:

B, 130 degrees.

If m > n, which inequalities must be true? Check all that apply. m + 2.1 > n + 2.1 m - (-4) > n -(-4) m + 3 > n-3 16.5 + m > 16.5 + n 1 m > n + 2 9 + m > 6 + 1

Answers

Let's begin by listing out the information given to us:

m > n

We will proceed to solve the inequalities given as shown below:

$\begin{gathered} If\colon m>n \n \n m+2.1>n+2.1 \n \text{Subtract ''2.1'' from both sides, we have:} \n m>n \n m+2.1>n+2.1\Rightarrow m>n \n \therefore m+2.1>n+2.1(TRUE) \n \n m-(-4)>n-\mleft(-4\mright) \n \Rightarrow m+4>n+4 \n \text{Subtract ''4'' from both sides, we have:} \n m>n \n m+4>n+4\Rightarrow m>n \n \therefore m+4>n+4(TRUE) \n \n m+3>n-3 \n \text{Subtract '3'' from both sides, we have:} \n m>n-3-3\Rightarrow m>n-6 \n m>n-6\ne m>n \n \therefore m+3>n-3(FALSE) \n \n \end{gathered}$

The last three choices are below:

$\begin{gathered} 16.5+m>16.5+n \n \text{Subtract ''16.5'' from both sides, we have:} \n m>n \n 16.5+m>16.5+n\Rightarrow m>n \n \therefore16.5+m>16.5+n(TRUE) \n \n m>n+2 \n m>n+2\ne m>n \n \therefore m>n+2(FALSE) \n \n \n \end{gathered}$

The inequalities marked as TRUE are the inequalities that apply
