M + 20 = 9
u need to subtract 20 from both sides because u want to isolate m
m + 20 = 9
m + 20 - 20 = 9 - 20
m = - 11

Answer: 42.84 kg
Step-by-step explanation: Lawn is 17 ft x 20 ft.
Its area is S = 17 x 20 = 340 ft²
Each ft² of lawn accumulates 1050 snowflakes/min, 1ft² = 1050 s.f./min.
As 1 hour has 60 min, the lawn accumulates 63000/hour →
1050 x 60 = 63000
1ft² = 63000s.f./hour
This way, 340 ft² of lawn will accumulate 21,420,000 s.f/hour →
340 x 63000 = 21420000
As 1 snowflake has 2mg, 21,420,000 will have 42,840,000 mg.
As 1kg = 1,000,000 mg
42,840,000/1,000,000 = 42.84 kg
A= P(1+r/n)^nt
P<span> =</span> principal amount (the initial amount you borrow or deposit)
r = annual rate of interest (as a decimal)
t<span> = </span>number of years the amount is deposited or borrowed for.
A<span> =</span><span> amount of money accumulated after n years, including interest.</span>
n = number of times the interest is compounded per year
A= 1100(1+0.343/12)^12/4
A = 1197.04
Amount saved = 1197.04 - 1100 = $ 97.04
Answer:
the probability is 0.24 or 24%
Step-by-step explanation:
Given
Percentage of time he goes out with his girlfriend = 40%
Percentage of time he goes out to a bar = 60%
If he goes out with his girlfriend, the percentage of times he spends the night at his girlfriend’s apartment = 30%
If he goes out to a bar, percentage of times he gets in a fight and gets thrown in jail = 40%
let probability that the roommate went to the bar = A
As the roommate going to jail is a conditional probability dependent on A happening, the true probability of the roommate is found by multiplying the absolute probability of the roommate going out to a bar (A) by the probability of the roommate going to jail if he goes to a bar
that is Pr(B) =Pr (B n A)
Pr(B) = Pr(B/A) *Pr(A)
This is given as 60% * 40% or 0.6 * 0.4 (probabilities are 1/100 of percentages)
This gives an answer of 0.24 or 24%
