X=0.3235 round to the nearest decimal you need to
Answer: biggest no.=27. Smallest number=9
Step-by-step explanation:
Let's take the smallest number as x and the biggest number as 3x since it is 3 times bigger than x.
The sum of these two numbers is 36
3x+x=36
4x=36
X( smallest number)=36/4: 9
While, the biggest number is 3x: 3×9=27
Hi!
34.287 rounded to the nearest tenth is 34.290
This is because 7 is greater than 5, so we would round it to the cloest tenth that is slightly higher than 7. =)
Answer:
$14.39
Step-by-step explanation:
The formula for continuous compounding of interest is:
A = Pe^(rt), were P is the initial dollar amount, A is the final amount, r is the interest rate as a decimal fraction, and t is the time in years.
Here we have $2109 = $500e^(10r) and need to solve for r.
To do this, take the natural log of both sides, obtaining:
ln 2109 = ln 500+ 10r.
Then 10r = ln 2109 - ln 500, and
ln 2109 - ln 500
r = --------------------------------------------
10
= .1439
The interest rate was 14.39%.
