Answer:

65.94

Step-by-step explanation:

Find the area of the smaller circle and subtract it from the area of the larger circle. This is the area of the shaded region.

Larger Circle - If d = 12.5, then the radius r = 6.25.

Area = π(6.25)² = 122.66

Smaller Circle - If d = 8.5, then the radius r = 4.25.

Area = π(4.25)² = 56.72

Shaded region - 122.66 - 56.72 = 65.94

Answer:

65.94 cm²

Step-by-step explanation:

12.5/2 = 6.25 = radius of large circle

8.5/2 = 4.25 = radius of small circle

A= πr²

A of large circle = 3.14(6.25²) = 122.66

A of small circle = 3.14 (4.25²) = 56.72

122.66 - 56.72 = 65.94 cm²

On a coordinate plane, 2 right triangles are shown. The first triangle has points A (negative 1, 3), B (negative 1, 1), C (3, 1)
drek231 [11]

Answer:

  • B and E

Step-by-step explanation:

<u>Given</u>

  • ΔABC ⇒ A(- 1, 3), B(- 1, 1), C(3, 1)
  • ΔA'B'C' ⇒ A'(2, - 2), B'(2, - 4), C'(6, - 4)

<u>Comparing the coordinates of the corresponding vertices, we see the difference:</u>

  • x → x + 3, y →  y - 5

It means the ΔABC has been translated 3 units right and 5 units down

Correct answer choices are B and E

At this market,6 batteries cost 10.38 how much do 8 batteries cost
3241004551 [841]
To find the cost of one, divide 10.38 by 6, so
10.38/6 = 1.73
1.73 = price per battery
To find the price of 8, multiply the cost of price per battery with however many items you need, in this case 8 so,
1.73 x 8 = 13.84

A clothing store spends $11 for each pair of shorts it produces and has fixed costs of $450. If the store makes 40 pairs of shor
zalisa [80]

Answer:

amt. the shop spends on 40 pairs

= $11 × 40

= $440

amt. paid extra (due to fixed cost) per pair

= ($450 - $440) ÷ 40

= $0.25

amt. per pair to break even

= $11 + $0.25

= $11.25

Find the value of x in each case:
goblinko [34]

Answer:

x = 11

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ FEB and ∠ DEB are adjacent angles and supplementary, thus

∠ FEB = 180 - 4x , so

180 - 4x + x = 147, that is

180 - 3x = 147 ( subtract 180 from both sides )

- 3x = - 33 ( divide both sides by - 3 )

x = 11
