Answer 2

Answer:

#3 points are
(-4, 2)
(4, 2)

(-4, -2)

(4, 0)

#4 scale factor = 1/4

#5 scale factor = 1/2

Step-by-step explanation:

take the given points and multiply the x and y by 2/3

#4 take any point and compare it to a similar point on the dilated graph. for example, you take a point from the original graph (-2, 4) and a point from the dilated graph (-1/2, 1) since you multiply -2 by 1/4 to get -1/2, that is your scale factor.

#5 same as #4 but with different points

(Question 1)

What are Corresponding Angles?

A pair of angles formed by two parallel lines and a transversal are said to be the corresponding angles.

Corresponding angles are formed only when,

One of them is interior and the other is exteriorThey are on the same side of the transversal andThey are not at the same vertex

The pairs of Corresponding Angles in the given figure are —

∠1 and ∠3∠2 and ∠4∠5 and ∠7∠6 and ∠8

You can write any two of them because the question says to write any two Corresponding Angles.

(Question 2)

What are Alternate Interior Angles?

Alternate angles that lie in the interior region of both the lines are called alternate interior angles.

Alternate Interior Angles are formed only when,

Each pair of alternate interior angles is equal.Each pair of co-interior angles is supplementary.

The pairs of Alternate Interior Angles in this given figure are —

∠2 and ∠7∠3 and ∠6

These are the only two pairs of Alternate Interior Angles.

(Question 3)

What are Alternate Exterior Angles?

Alternate angles that lie in the exterior region of both the lines are called alternate exterior angles.

Alternate Exterior Angles are formed only when,

Both lie on the exterior side of the lines.They are placed on the opposite sides of the transversal.

The pairs of Alternate Exterior Angles in this given figure are —

∠1 and ∠8∠5 and ∠4

These are the only two pairs of Alternate Exterior Angles.

(Question 4)

In this given Figure, Line segment AB is parallel to Line segment CD.

∠1 = 154° [Alternate Interior Angles]

∠2 = 180 - 154° [Linear Pair]

= 26°

(Question 5)

In this given Figure, Line segment AB is parallel to Line segment CD.

∠1 = 97° [Corresponding Angles]

∠2 = 82° [Corresponding Angles]

∠3 = 180 - 97° [Linear Pair]

= 83°

2. The area of the trapezoid is 3, 584. 88 centimeters square

3. Area = 468, 975 ft²

4. Area = 3682. 04 m²

5. 94, 386. 93 mi²

How to determine the area

The formula used for calculating the area of a trapezoid is expressed as;

A = 1/2h( a + b)

Such that the parameters are given as;

A is the area of the trapezoidh is the height of the trapezoida and b are the side lengths

Substitute the values, we have;

Area = 1/2 × 23. 4(61. 2 × 92)

multiply the values

Area = 1/2 × 23.4(153.2)

multiply the values

Area = 1/2(3584. 88)

Now, divide the values, we get;

Area = 3, 584. 88 centimeters square

3. Area = 1/2 × 555 (463 + 1227)

Add the values

Area = 1/2 × 555(1690)

multiply the values

Area = 468, 975 ft²

4. Area = 1/2 × 63 × (41. 56 + 75.33)

add the values

Area = 1/2 × 63 × (116. 89)

multiply the values

Area = 3682. 04 m²

5. Area = 1/2 × 306. 7 (206. 6 + 408. 9)

You then plug it into area formula (pi r squared)
*pi = 3.14*
use a calculator and type in 3.14(8)^2
you will get 201 (rounded)
Second find the area of the square which is 12 times 12 equals 144

One tape diagram equals 9, one is divided into 6 equal parts, each equals t.

6t's make up a diagram that is equal to a diagram equal to 9.

therefore 6t=9

A waitress sold 15 ribeye steak dinners and 28 grilled salmon dinners, totaling $551.97 on a particular day. Another day she sold 24 ribeye steak dinners and 14 grilled salmon dinners, totaling $581.91. How much did each type of dinner cost?

Answers

Answer:

Ribeye (ea) = $18.54

Salmon (ea) = $9.78

Step-by-step explanation:

x is the price for each ribeye steak

y is the price for each grilled salmon

15x + 28y = $551.97 (a)

24x + 14y = $581.91 (b) -----(x2)------> 48x + 28y = 1163.82 (c)

Subtract c with a

48x + 28y = 1163.82 (c)

15x + 28y = $551.97 (a)

=================== -

33x = 611.85

x = 18.54

Put the value of x into a

15 · 18.54 + 28y = 551.97

278.1 +28y = 551.97

28y = 273.87

y = 9.78

In conclusion, the price of 1 ribeye is $18.54, and the price of 1 salmon is $9.78.

Ribeye is 18.54 and salmon is 9.78

I haven't done anything like this for many years, but i think the answer is 900

Step-by-step explanation:

5000/ 150 = 33.33333333

33.3333333 X 27 = 900

Again, I haven't done this in forever, but I'm 99% sure it is 900. :)

900 would be the answer because;

27/150= 0.18
so 18% of the 150 people like mustard
then 0.18 x 5000= 900

A store is running a "buy 3 get 2 free" promotion on twelve-packs of soda. Each twelve-pack costs $5.49. How much will Peter pay for 25 twelve-packs of soda?

Answers

Answer: $82.35

Step-by-step explanation:

For every 3 you buy, you get 2 free. This means out of every 5 twelve-packs, you pay for 3 of them, or 60%.

3/5 = 0.6 or 60%

So, if you buy 25 of them, you pay for 60% of 25 twelve-packs, or 15 of them.

25 x 0.6 = 15

If you are paying for 15 twelve-packs, and each one is $5.49, then the total would be $82.35.

15 x 5.49 = 82.35

Answer:82.35

Step-by-step explanation:

For every 3 you buy, you get 2 free. This means out of every 5 twelve-packs, you pay for 3 of them, or 60%.

3/5 = 60%

if you buy 25 of them, you pay for 60% of 25 twelve-packs, or 15 of them.

25 x 0.6 = 15

15 twelve-packs, each one is $5.49, then the total would be $82.35.

15 x 5.49 = 82.35
