At first, the beat needed to be more than ten seconds, so the beat could be more than or equal to 11 seconds. then, the beat has to be five seconds more than that, so the beat has to be more than or equal to 16 seconds.
so the beat could be 16 ≤ 17 seconds, 16 ≤ 18 seconds, or 16 ≤ 100 seconds. as long as it's more than 16 seconds it would work.
Answer:
23, 32, 69
Step-by-step explanation:
3 numbers x, y, z
z = 3x
y = x + 9
x+y+z=124
x + (x + 9) + 3x = 124
5x + 9 = 124
5x = 115
x = 23
y = 32
z = 69
check: 23 + 32 + 69 = 124
Answer:
C. 54π + 20.25√3 cm²
Step-by-step explanation:
The shaded area can be split into two areas: a sector and an isosceles triangle.
Area of a sector is:
A = (θ/360°) πr²
where θ is the central angle and r is the radius.
Area of an isosceles triangle can be found with SAS formula:
A = ½ ab sin θ
where a and b are two sides of a triangle and θ is the angle between them.
In this case, r = a = b = 9 cm. The central angle of the sector is 240°, and the vertex angle of the triangle is 120°. Therefore, the total area is:
A = (240°/360°) π (9 cm)² + ½ (9 cm) (9 cm) sin 120°
A = 54π + 20.25√3 cm²
