B) 36
To figure this out you need to average the numbers. To average them you add them all up and divide by how many are there.
(60+30+20)/3
(90+20)/3
110/3
36
Answer:
a
Step-by-step explanation:
A compound event is an event that has more than one outcome. it is the combination of two simple events
Answer:
A = pi*(8 mm)^2 = 64*pi mm^2
Step-by-step explanation:
The formula for the area of a circle is A = pi*r^2, where r is the radius. Thus, r^2 = (25pi) / pi, or 25, and r = 5 mm.
If we increase this radius by 3 mm, we get the new radius 8 mm. The area of the new circle will thus be A = pi*r^2, or, in this particular case,
A = pi*(8 mm)^2 = 64*pi mm^2.
Answer:
x = 55° (nearest degree)
Step-by-step explanation:
Trig ratios:
where 
is the angle, O is the side opposite the angle, A is the side adjacent to the angle, and H is the hypotenuse of a right triangle
Given:
- A = 3.3
- H = 5.7
⇒ x = 55° (nearest degree)
