She ran for 2 and a half hours
12.5/5=2.5
I won't give you answers but I can tell you how to figure it out...
Area of a circle = pi * r^2
A = (3.14) * 8^2
A = 3.14 * 64
A =200.96 units ^2
She has 21 eggs total; 7*3 is 21 and it can't be grouped by those numbers.
Answer:
12) 5.96 ; 13)
Step-by-step explanation:
12). x and 5 are legs, so
opposite leg/adjacent leg = tangent 40°
5/x= tan40°, 5= x*tan40°, x= 5/tan40° ≈ 5.96
13). 15 is opposite leg
24 is hypotenuse
opposite leg/hypotenuse = sin(x)
sin(x) = 15/24
x = arcsin(15/24) ≈ 38.68°
