Holly invests $1000 in an account that pays an interest rate of 6.25%. how many years will it take for the account to reach $5500? round your answer to the nearest hundredth.

It takes 72 years to get $5500.

Step-by-step explanation:

The amount in her bank account increases as she gets interest at a rate of 6.25% per annum.

Let A be the final amount , P be the principal amount , r be the rate of interest and t be the number of years taken.

A = P ( 1 + rt )

The final amount = $5500

Principal = $1000

r = 0.0625

Substituting the above values in the given equation,

5500 = 1000 (1 + 0.0625t)

t =

t = 72 years.

It takes Holly 72 years to get $5500 amount from her bank.

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:

answer: 12,000
