Answer:

  $0.55

Step-by-step explanation:

Since you're only interested in the "a" variable, you can eliminate r from the system by subtracting 5 times the second equation from 12 times the first.

  12(5r +15a) -5(12r +11a) = 12(10.5) -5(11.45)

  60r +180a -60r -55a = 126 -57.25

  125a = 68.75

  68.75/125 = a = 0.55 . . . . . . . the cost of each apple

enot [183]

Answer:

Step-by-step explanation:

22.75/6 boxes is $3.79 per box

30/8 boxes is $3.75 a box

38/10 boxes is $3.80 a box

68/18=3.70 a box if you combine the last two.

So no, the 6 boxes at $3.79 a box is not a better buy.

Please help me i will give u brainliest

Answer:

A ≈ 9.0 ft²

Step-by-step explanation:

70° = 7π/18 radians

Area of the arc section

A = ½(7π/18)8² = 12⁴/₉π ft² = 39.09537 ft²

As the triangle is isosceles, the other two angles are (180 - 70) / 2 = 55°

law of sines 8 / sin55 = L / sin 70  L = 9.17722

so the triangle height  = √(8² - (9.17722/2)²) = 6.55321

Area of triangle ½(6.55321)(9.17722) = 30.07016

Area = 39.09537 - 30.07016 = 9.025211 ≈ 9.0 ft²
