Answer:
The value of Mary's investment after two years = £12362.7
Step-by-step explanation:
P = Principal / initial amount
R = rate of interest per cent per year
T = number of years
A = final amount at the end of T years
Then:
A = P*(1 + R/100)^2
In our example:
P = £12000
R = 1.5 per cent per year
T = 2 years
Thus:
A = 12000*(1 + 1.5/100)^2
= 12000*(1 + 0.015)^2
= 12000*(1.015)^2
= 12000*(1.030225)
= 12362.7
Value of investment after two years = £12362.7
Answer:
Now, to answer the question, we need to add the weight of (58-42) = 16 gallons of fuel to the weight of the plane
carrying 42 gallons of fuel, 2331 pounds.
So, the answer is 2331 + 16*5.5 = 2419 pounds.
Green or purple = 10
prob(green or purple) = 10/30 = 1/3
Since the diameter of the cylinder is 10, its radius is half that, or 5, thus
