Answer:
≈ 565.5 units²
Step-by-step explanation:
The area (A) of the shaded sector = area of circle × fraction of circle
A = πr² ×
← r is the radius
= π × 20² × 
= 400π × 0.45 ≈ 565.5 units²
Base = 2 x height (b = 2h)
Area = 1/2 x base x height = 1/2 x 2h x h = h x h = h^2
A. 11/30 x 50= 18/36=1/2
18/36 x 1/10= 5/100
B. 1,210 x 1.1= 1,331
I am not so sure about A, but I hope this helps a little.
Answer:
The number of children's tickets sold was 31 and the number of adult tickets sold was 2
Step-by-step explanation:
Let
x ---> the number of children's tickets sold
y ---> the number of adult tickets sold
we know that
the theater sold 33 tickets
so
-----> equation A
the theater made a total of $158.50
so
----> equation B
Solve the system by graphing
Remember that the solution of the system is the intersection point both graphs
using a graphing tool
The solution is the point (31,2)
see the attached figure
therefore
The number of children's tickets sold was 31 and the number of adult tickets sold was 2
26 gold metals
Explanation: 70 - 18 silver = 52 metals left
52/2= 26 … so 26 + 26= 52 52 + 18=70
