Answer:
13/52 (0.25) (25%)
Explanation:
There are 52 cards in a standard deck and there are four suits.
52/4 = 13
So, the probability (assuming that’s what you are asking for) is a 13/52 chance you will pull a hearts card.
The mass of substance left after 7 days is 13.09 g
The mass of substance left, N is given by
N = N₀exp(-λt) where λ = decay constant and N₀ = initial mass of substance present = 24 g and t = time
Also, λ = 0.693/t' where t' = half-life of iodine = 8 days
So, λ = 0.693/t'
λ = 0.693/8
λ = 0.086625/day
Since the mass of substance left is N = N₀exp(-λt) and we require the mass of substance after t = 7 days,
N = N₀exp(-λt)
N = 24 gexp(-0.086625/day × 7 days)
N = 24 gexp(-0.606375)
N = 24 g × 0.5453
N = 13.09 g
So, the mass of substance left after 7 days is 13.09 g

Answer:
See below in bold.
Step-by-step explanation:
The angle below and to the right of 30 degrees = 90-30 = 60 degrees,.
< EAC + 5x + 6x = 180
But m < EAC = the angle found in first line so its 60 degrees.
S0 3x + 5x + 60 = 180
8x = 120
x = 15
So m < CAB = 75 degrees and m < BAH = 45 degrees.
Finally the m < on top left = 90 degrees.
