In degrees,
arccos(0.36) = 68.89980398 ≈ 68.9°
In radians,
arccos(0.36) = 1.202528433 ≈ 1.20
Answer:
Step-by-step explanation:
both represent the same line .
Hence it has infinite solutions as there are infinite points on aline.
The triangle in the drawing is semi equilateral. Therefore a=√(14^2-7^2)=12.12 cm
The base of a regular pyramid consists of 6 equilateral triangles. The area of each triangle is: (14*12.12)/2 = 84.87 cm^2
The base: 6*84.87=509.22 cm^2
Answer:
C) 161/163
Step-by-step explanation:
First, you add up all the students for both genders.
Female- 193+ 214 +197+ 201 = 805
Male- 216+ 207+ 198 + 194 = 815
That gives you a fraction on 805/815 which you simplify to 161/163
So your answer would be C, 161/163 :)
It will take 2.5 hours
125km / 50km/h = 2.5h to go 125 km
