A)
D+Y=50
D=Y+10
b)
Y+10+Y=50
2Y+10=50
2Y=40
Y=20
Therefore there are 20 in yearbook and 30 in drama.
To check our work:
D=Y+10
30=20+10
30=30 [CHECKS TRUE]
40 + 40 + 40x2
= 40 + 40 + 80
= 160
The area (A) of a regular hexagon in terms of its side length s is
... A = (3√3)/2·s²
For a regular hexagon, its side length is equal to the radius of its circumcircle, given here as 10√3 cm. Putting this value in the formula gives
... A = (3√3)/2·(10√3 cm)² = 450√3 cm²
... A ≈ 779.4 cm² . . . . area of the hexagon
