Final Answer:

Answer: The square

Step-by-step explanation:

The square has a 90 degree angle which is a right angle. Also all sides have the same length

The scale factor is always the ratio of new image with respect to the old image.

6) The scale factor as per the image is 3:1 or 3.

7) The New image is P'Q'R'S' and old image is PQRS so the scale factor is given by:

Q'R':QR=3:6 or 1:2.

The scale factor is 1/2.

8) Here the pair of congruent angles is:

The proportional sides are:

So FG corresponds to RS, GH corresponds to TS, HF corresponds to TR.

Answer:

Length: 10 m

Width: 6 m

Step-by-step explanation:

The layout of the floor is l x w, which is 100 cm by 60 cm. Now, the confusing part: 1 meter (m) = 10 centimeters (cm)

To set this problem up, you'd first have to go through the logic. For every 10 centimeters of the floor layout, it is equal to 1 meter of the actualy floor plan. So you would have to scale 100 cm and 60 cm by [tex]\frac{1}{10}[/tex] (or divide by 10).

We will ignore the units, for now

Length: 100 * [tex]\frac{1}{10}[/tex] = 10    or    (100/10 = 10)

Width: 60 * [tex]\frac{1}{10}[/tex] = 6       or    (60/10 = 6)

Now that we've finalized the numerical value, lets move on to the units. Since the question wants us to respond in meters, the length of 10 and the width 6 6 would be in meters.

So the answer would be:

Length: 10 m

Width: 6 m

Answer:

Top: y = x

Bottom: y = 0.8x - 3.2

Step-by-step explanation:

I can see the question is asking to write the equation in Slope-Intercept form.

Slope-Intercept Form:

y = mx+b

M is the slope or how much the y value increases every time the x value increases by one. b is the y-intercept or when x=0.

Because these lines are parallel, we know they have the same form.

Lets look at the top line. When x increases by one, how much does y increase by?

1

What is the y value of when the line's x-value is 0?

0

Now, we have,

y = 1x + 0

Because adding 0 keeps the equation the same, we can remove it.

y = 1x

Because multiplying a term by 1 leaves it the same, we can remove one.

y = x

Now, for the bottom line.

How much does y increase by when x increases by 1? Because the slope will be a fraction and is not easy to see, I will use the slope formula.

Slope Formula:

[tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]

To find the slope, take any pair of points on the line and plug them in.

I'll use:

(0,-3.2)

(4,0)

Plug the y-values (the latter number, or the height of the point) into the formula. Do the same with the x-values. keep in mind it does not matter what y-value you plug in. For example, for [tex]y_2[/tex] and [tex]y_1[/tex] you can plug in -3.2 and 0 or vice versa. If you make [tex]y_2[/tex] -3.2, then make [tex]x_{2}[/tex] 0.

[tex]\frac{-3.2-0}{0-4}[/tex]

Simplify.

[tex]\frac{-3.2}{-4}[/tex]

Because a negative number multiplied or divided by another negative number is always a positive number, remove the negative signs.

[tex]\frac{3.2}{4}[/tex]

Divide.

3.2/4 = 0.8

Now we have m, the slope on the 2nd line, 0.8

y = 0.8x + b

What is the y-value of the line when the line has the x-value of 0? On the graph, it says -3.2.

y = 0.8x - 3.2

The equation has 2 irrational roots and two real distinct solutions.

It is a solution to an equation that occurs only once and differs in value from other solutions.  If the discriminant is zero, there are no real solutions. The discriminant equation is Δ = b² - 4ac. If the discriminant is greater than zero it has two irrational roots. Another alternative for a distinct solution is the coincident solution. The values of the discriminant show how many roots and solutions the equation may contain.

Given, 2x² - 6x - 15 = - 7

The discriminant of the equation is D = b² - 4ac

Here, a = 2, b = - 6, c = - 15

D= 36 - 4(2)(-15)

36 + 120 = 156

Here, D > 0 and it is not a perfect square.

So, the equation has 2 irrational roots.

And the equation has two real distinct solutions.

Let's see the facts:

%Earns= 13% commission/week

Last week sold = $7,500

In order to obtain the last week earns in commission we need to multiply % rate of commission by the last week sold as shown as follows:

$Earns = 0.13 (decimal form)*$7,500

Earns = $975

Last week, he made $975 in commission.

If he averages that same amount each week, he should make $975* 52(number of weeks per year) = $50,700/year

The number of Screamers when Runners are 6 is 4,

and the number of Runners when Screamers are 10 is 15.

It is basically the measurement of two numbers and it compares by how much one quantity is bigger than another.

When two ratios are equal, they are usually said to be in proportion.

As given in the above questions,

Screamers:Runners= 2:3

So, let the number of screamers in first case is x

Then, x:6 = 2:3

         x= 4

Hence , the number of screamers is 4.

In second case, let the number of runners is y

Then, 10:y = 2:3

          y= 15

Hence , the number of runners is 15.

The slope intercept form of the required line is 2x - y = -8

What is equation of line in slope intercept form?

The most general form of equation of line in slope intercept form is given by y = mx + c

Where m is the slope of the line and c is the y intercept of the line.

Slope of a line is the tangent of the angle that the line makes with the positive direction of x axis.

If  [tex]\theta[/tex] is the angle that the line makes with the positive direction of x axis, then slope (m) is given by

m = [tex]tan\theta[/tex]

The distance from the origin to the point where the line cuts the x axis is the x intercept of the line.

The distance from the origin to the point where the line cuts the y axis is the y intercept of the line.

Slope of the line = 2

The line passes through (-8, -8)

Equation of the required line-

[tex]y - (-8)= 2(x - (-8))\\y + 8 = 2(x + 8)\\y + 8 = 2x + 16\\2x - y = 8 -16\\2x - y = -8[/tex]
