That's a 240 degree sector of a 9 inch radius circle.  The whole circle has area πr² and we want 240/360 of it.

A = (240/360) π (9²) = 54 π

Answer: 54 π square inches

That's the exact answer.  An approximation is

169.646 square inches

Answer:

to find the equivalent positive angle of a negative angle, just add 360 to it until it becomes positive and is between 0 and 360 degrees. -244 + 360 = 116.

Answer:

a° = 58°

b° = 48°

c = 74°

d° = 122°

Step-by-step explanation:

<em>Angles on a straight line add up to 180°</em>

58° + d° = 180°

d° = 180° - 58° = 122°

<em>Alternate angles are equal.</em>

a° = 58°

<em>Angles in a triangle add up to 180°.</em>

48° + 58° + c° = 180°

106° + c° = 180°

c° = 180° - 106° = 74°

<em>Angles on a straight line add up to 180°</em>

74° + 58° + b° = 180°

132° + b° = 180°

b° = 180° - 132° = 48°

Lemon drops and jelly beans are mixed to make a 100 pound mix. if the lemon drops cost $1.90 per pound and jelly beans cost $1.2
vladimir1956 [14]

L = lemon drops

J = jelly beans

L +J = 100

L=100-J

1.90L + 1.20J=1.48*100

1.90(100-j) +1.20J =148

190-1.90J+1.20J=148

190-0.7J=148

-0.7J=-42

J = 60

L=100-60 = 40
