Total=14+20+16=50
P(blue)=20/50=2/5
so, answer=(2/5)*40=16
Answer:
h = 6 units
Step-by-step explanation:
The formula for the volume of a tetrahedron is given as :
V = sh
Where
s is area of base and h is height
Put s = 8 and V = 48 to find h as follows :

So, the height of the tetrahedron is 6 units.

Answer: x = -2 and 4
Step-by-step explanation:
x^2 - 2x - 8 = 0
(x - 4)(x + 2) = 0
Using Pythagorean theorem, the answer should be 8.7ft
