jeka94

Answer:

  • Maria–Ava: 15.7 feet
  • Lucas–Maria: 10.1 feet
  • angle at Maria: 50°

Step-by-step explanation:

The cosine and tangent functions are useful here. The relevant relations are ...

  Cos = Adjacent/Hypotenuse

  Tan = Opposite/Adjacent

__

The distance from Maria to Ava (ma) is the hypotenuse of the triangle, so we have ...

  cos(40°) = 12/ma

  ma = 12/cos(40°) ≈ 12/0.76604 ≈ 15.7 . . . feet

__

The distance from Lucas to Maria (ml) is the side opposite the given angle, so we have ...

  tan(40°) = ml/12

  ml = 12·tan(40°) ≈ 12·0.83910 ≈ 10.1 . . . feet

__

The angle formed at Maria's position is the complement of the other acute angle in the right triangle:

  M = 90° -40° = 50°

In summary, ...

  • Maria–Ava: 15.7 feet
  • Lucas–Maria: 10.1 feet
  • angle at Maria: 50°

Which ordered pairs make both inequalities true? Check all that apply.
Thepotemich [5.8K]
All others did not satisfy the inequality simultaneously except #4 and #6
For #4:
2 < 5(1) + 2 i.e. 2 < 7 (true)
2 >= 1/2(1) + 1 i.e. 2 >= 3/2  (true)
For #6
2 < 5(2) + 2 i.e. 2 < 12 (true)
2 >= 1/2(2) + 1 i.e. 2 >= 2

1/2 X plus X -15+1/2 X +100+ X -25 equals 540
Andrew [12]

Answer:

1/2 X + X -15 + 1/2 X + 100 + X -25 = 540

1/2x + x + 1/2x + x -15 + 100 -25 = 540

3 x + 60 = 540

3x + 60 - 60 = 540 - 60

3/3x = 480/3

x = 160

Step-by-step explanation:

1/2 X + X -15 + 1/2 X + 100 + X -25 = 540

1/2x + x + 1/2x + x -15 + 100 -25 = 540

3 x + 60 = 540

3x + 60 - 60 = 540 - 60

3/3x = 480/3

x = 160
