Answer:
65.3 cm
Step-by-step explanation:
The law of sines can be used for this.
g/sin(G) = f/sin(F)
g = (37 cm)sin(124°)/sin(28°) ≈ 65.3 cm . . . . multiply by sin(G)
The length of g is about 65.3 cm.
Answer:
C $320
Step-by-step explanation:
write equations for the two possible choices
situation 1:
y₁ = 20 + 0.5x, where y is the total price the club pays and x is the sales
** note i use 0.5 instead of 50, since 50 would represent 5000%
y₂ = 100 + 0.25x, where y is the total price the club pays and x is the sales
now set the two equations equal to each other
20 + 0.5x = 100 + 0.25x
isolate x by subtracting 0.25x and 20 from each side
20 + 0.5x - 0.25x - 20 = 100 + 0.25x -0.25x -20
0.25x = 80
divide both sides by 0.25
=
x = 320
The circumference of a circle can be found by multiplying pi ( π = 3.14 ) by the diameter of the circle. If a circle has a diameter of 4, its circumference is 3.14*4=12.56. If you know the radius, the diameter is twice as large.
