Answer:
B) 10 m
Step-by-step explanation:
Area is 20 and Height is 4
Ok so
AREA of a triangle is =1/2Base Times Height
work back
Area=20
Height=4
b=Base
20=1/2b*4
Simplify both sides of the equation.
20=2b
Flip equation
2b=20
Divide both sides by 2
b=10
Base=10 m
Answer:
or 
Step-by-step explanation:




For sin θ = 0.5, the reference angle is θ = 30 deg.

or 
30% = .3
.3(24.40a + 14.50c)
24.40 = cost of adult ticket
14.50 = cost of child ticket
a = # of adult tickets sold
c = # of child tickets sold
.3 * 24.40a + .3 * 14.50c
answer: 7.32a + 4.35c
