Answer:
we could work this out by geometric sequence
Step-by-step explanation:
G1=2, G2=4, we have a formula,Gn=G1r^n-1
G2=G1 (r)^1, 4=2r, r=2
G30=G1 (2)^29=1,073,741,824 bacterium
Answer:
measure of each angle of a regular octagon=360/8=45°
at the point, 60°+x+45=360°
x=255°
Answer:
11.56
Step-by-step explanation:
Answer:
3/4 inches per hour
Step-by-step explanation:
3 in. = 4 hr.
Divide both sides by 4 : 3/4 in. = 1 hr.
Step-by-step explanation:
speed: 510mph
50 min = 5/6 hours
distance = 510 x 5/6 = 425miles
