Answer:
choices A and F are part of Leo's system of equations
Step-by-step explanation:
The formula for the amount in an account compounded annually is ...
A = P(1 +r)^t
For the given amounts and variables, that is ...
y = 500(1.025)^x . . . . matches F
__
The formula for the amount in an account compounded continuously is ...
A = P·e^(rt)
With given values, this is ...
y = 400e^(0.02x) . . . . matches A
Answer:
22 3/4 ft
Step-by-step explanation:
The diagram seems to show a 6 1/2 ft person casting a 9 ft shadow at the same time a flagpole is casting a 31 1/2 ft shadow. You want the height of the flagpole.
<h3>Proportion</h3>
Shadow lengths are presumed proportional to the height of the object making them. This means ...
h/(31 1/2) = (6 1/2)/9 . . . . . all lengths in feet
Multiplying by 31 1/2, we get ...
h = (31 1/2)(6 1/2)/9 = (819/4)/9 = 91/4
h = 22 3/4 . . . . ft
The flagpole is 22 3/4 feet tall.
Answer:
30
Step-by-step explanation:
the answer is 30 because if you count by 6 it would go 6,12,18,24,30,36,42 and if you go by 15 it would be 15,30,45,60,75,90..... and the only number that you see twice is 30 so the answer would be 30. Hope this helped...
