Answer:

  A. <dilation by a factor of 1/7>

Step-by-step explanation:

Rotation, reflection, and translation are "rigid" motions that preserve congruence.

Dilation does not preserve congruence. Dilation multiplies the coordinates by a dilation factor, as in the transformation of choice A.

  (x, y) ⇒ (x/7, y/7) . . . does NOT preserve congruence

Answer:

The answer is 12.566 or 12.57

Step-by-step explanation:

The formula for the area of a circle is [tex]\pi[/tex]r²

∴ 3.14×(2)² is equal to 12.566 or 12.57

Answer:

angle APD=115 degrees

angle CPE=25 degrees

angle BPD=65 degrees

Step-by-step explanation:

APD=180-65=115 because it is supplementary

CPE=90-65=25 because it is complementary

BPD=65 because it is an alternate angle

The measurements of the asked angles are m ∠APD = 115°, m ∠CPE = 25° and m ∠BPD = 65°.

An angle is a geometrical shape that is formed by two rays or lines, called the sides or arms of the angle, that share a common endpoint, called the vertex of the angle.

Given is a figure, we need to find the measurement of the asked angles,

m ∠APD, m ∠CPE and m ∠BPD.

So,

∠APD + ∠APC = 180° [linear pair]

∠APD = 180° - 65°

∠APD = 115°

∠CPE + ∠CPA = 90° [complimentary angles]

∠CPE = 90° - ∠CPA

∠CPE = 90° - 65°

∠CPE = 25°

∠BPD = ∠APC [vertical angles]

∠BPD = 65°

Hence, the measurements of the asked angles are m ∠APD = 115°, m ∠CPE = 25° and m ∠BPD = 65°.

Answer:

$1792

Step-by-step explanation:

$78 x 28 = 2184

28 x $8 = 224

28 x $6 = 168

168 + 224 = 392

2184 - 392 = $1792

Check Work:

1792 + 392 = 2184

2184 / 78 or 2184 / 28

Answer:

(7x+2)(3x-1); (5x+4)^2 or (5x+4)(5x+4);

Step-by-step explanation:

formula to find area is L* W = A ; meaning length multiplied by width equals to the area.

21.

using the formula to find area...

l*w=a

(7x+2)(3x-1) would be your answer

btw, don't put the "=a" at the end, since it's an expression :))

22.

since the problem states that it's a square, you can just say either...

(5x+4)^2 or (5x+4)(5x+4) not sure which one your teacher accepts

The calories from the different diets are given below.

1.  2,000 calories diet eat from veggies than from carbs is 200 calories.

2.  1,800 calories diet from fruit is 270 calories.

3.  2500 calorie diet, healthier because they eat more calories is not accurate.

4.  2200 calorie diet eat from protein is 550 calories. Then option B is correct.

The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.

1.  The calories should a person on a 2,000 calories diet eat from veggies than from carbs will be

→ 2000 × 0.35 = 700 calories

→ 2000 × 0.25 = 500 calories

→700 – 500 = 200 calories

2.  If a person is on a 1,800 calories diet, then the calories will come from fruit will be

→ 1800 × 0.15 = 270 calories

3.  A person on a 2500 calorie diet states that they are healthier because they eat more calories from veggies will be

→ 2500 × 0.35 = 875 calories

Because veggies have more calories than others. Thus, inaccurate.

4.  The number of calories from protein a person on a 2200 calorie diet should consume will be

→ 2200 × 0.25 = 550 calories

Answer:

58.9 m

Step-by-step explanation:

To find the width, use the area by dividing 215.2/16 to get 13.45. You now have the length and the width so add 16 + 16 + 13.45 + 13.45. You get 58.9.
