Answer:
3:1
Step-by-step explanation:
Take the fraction and simplify it:
12/4 = 3/1
Answer:
15 per hour
Step-by-step explanation:
120 people / 8 hours = 15 peeps per hour!
You start with 100%, add 80% for the increase and you get 180%, take away 40% for the decrease and you get 140%
The area of a sector is given by the formula
... A = (1/2)r²·θ . . . . . where r is the radius, and θ is the central angle is radians
Your angle is given in degrees, so we need to multiply it by π/180° to find its equivalent in radians.
... A = (1/2)(7.13 ft)²·(50°)·(π/180°) ≈ 7.0607π ft² ≈ 22.2 ft²
A = bh/2
40 = x(2x)/2
80 = 2x²
40 = x²
x = sqrt40
x = +/- 2sqrt10
Measurement cannot be negative therefore x = 2sqrt10
Height = 2x = 2(2sqrt10) = 4sqrt10
The height of the triangle is 4sqrt10 cm or approximately 12.65cm.
