so
convert every body to scientific notation
(number less than 10 but equal to or greater than 1) times (10^x)
baby=26,000,000,000
how many decila places to move to left to make less than 10 but equal to or great than 1
10
there for it can be writtten as
2.6*10^10
how many times bigger is adult than baby
baby times x=adult
divide adult by baby with the numbers
x==
times =

Since the probability of the coin landing leads is 1/2, simply cube 1/2 to arrive at your answer: 1/8.
You cube 1/2 because you must land heads three times in a row and each flip is independent from other flips.
The other sides are 12cm and 5cm. This is a Pythagorean triple. It is useful to know them!!!

Answer:
y = 40 x = 80
Step-by-step explanation:
520 = 3.25x + 6.5y x+y=120
x+y=120
x = 120-y
520 = 3.25(120-y)+6.5y
520 = 390-3.25y+6.5y
520 = 390+3.25y
130=3.25y
Divide each side by 3.25
40 = y
x = 120-y
x = 120-(40)
x = 80
