Answer: 39 years, 10 months
Step-by-step explanation:
Here is the complete question:
Odessa deposited $1,347.80 into a savings account with an interest rate of 3.3% compounded monthly. About how long will it take for the account to be worth $5,000?
The formula for compound interest is:
= A=P(1+i)^n,
where
P =initial investment = $1347.80
i = interest rate = 3.3% = 0.033/12 = 0.00275
n = number of periods = Unknown = ?
A = amount after n-periods = $5000
We slot the values into the formula. This will be:
A=P(1+i)^n
5000=1347.80(1+.00275)^n
Divide both side by 1347.80
5000/1347.80 = (1.00275)^n
We then take the log of both sides. This will be:
log(5000/1347.80) = nlog(1.00275)
n=log(5000/1347.80)/log(1.00275)
n = 477 months approximately
= 477months/12
= 39 years, 10 months
48.9 - 29.7 = 19.2...so there was an increase of 19.2 lbs in an 8 month period.
19.2 / 8 = 2.4....thats an increase of 2.4 lbs per month
Answer:
Step-by-step explanation:
'll just help with proving whether she is correct.
First of all, a fraction divided by a fraction can be made into multiplication since the division of two fractions is kinda difficult
so remember keep, change, flip
keep the first fractions, change the division symbol into multiplication, then flip the fraction i.e. 1/2 becomes 2/1
so 5/2 divided by 1/4 becomes
5/2 * 4/1
which then solved becomes
20/2 which is simplified to 10
Hope this helps :)
3 minutes because half of 6 is 3 so 3 is the anwser.
The slope of line that passes through given points is -1/2
Step-by-step explanation:
The formula for slope is:
Given points are:
(-2,-1) = (x1,y1)
(2,-3) = (x2,y2)
Putting the values in the formula of slope
m =
The slope of line that passes through given points is -1/2
