Answer:
20 males, 7 females
Step-by-step explanation:
x=males
x-13=females
x+x-13=27
2x-13=27
2x=40
x=20
20-13=7
1.7/1.9 = 0.894 (rounded)
The correct value of the angle of rotation is 3π/5
Answer:
Distance travelled ≈ 22.6 ft
Step-by-step explanation:
We are given;
Radius;r = 12 ft
Angle of rotation; θ = 3π/5
The formula for calculating distance travelled is;
Distance travelled = rθ
So, plugging in the relevant values;
Distance travelled = 12 x 3π/5
Distance travelled ≈ 22.6 ft
Answer:
A = 4 cm²
Step-by-step explanation:
The area of a triangle is calculated as
A = 
bh ( b is the base and h the perpendicular height )
b = AC = 3
+ = 4
h = BD
Calculate BD using Pythagoras' identity in Δ ABD
BD² = AB² - AD²
= (2
)² - (3 )²
= 20 - 18 = 2 ( take square root of both sides )
BD =
Then
A = × 4 × = 2 × × = 4 cm²
