Ok so what you need to know about an octahedron is it's basically two square pyramids stacked on top of each other (one is upside down of course).
The formula for volume of a pyramid is Bh/3.
Base= 8*8=64
Height= 3 each
64*3/3= 64 mm^3 per pyramid.
64*2=128 mm^3 for the octahedron
Final answer: 128 mm^3
Answer:
6 13/16
Step-by-step explanation:
Make it a fraction for it to be easier to solve.
11/4 + 65/16
The LCM is 16
44/16+65/16
109/16
6 13/16
Answer:
3 mph
Step-by-step explanation:
Find the following:
5 miles 5 miles
---------------- = ----------- = 3 mph
1 2/3 hr 5/3 hr
The correct answer is A) t = 1-s.
The probability of the complement of an event is the probability of the event subtracted from 1; in other words
P(A') = 1 - P(A)
Since P(A') = t and P(A) = s,
t = 1-s
