Is 14 times 10 to the power of 8 in scientific notation?

NO

Step-by-step explanation:

14 × 10^8 is not in scientific notation

scientific notation: a×10^b, where should be 0<a<10

As seen above, 14 is greater than 0, but also greater than 10, thus, it is not in scientific notation.

EXTRA: How to change it into proper scientific notation

To change it into scientific notation, we need to divide 14 by 10, do get 1.4. (or just move the decimal point to the left by 1 unit)

1.4 is within the range of 0-10.

1.4 × 10^9 (remember, we just divided 14 by 10, and so we need to add on the exponent by 1)

Hope this helps!! :)

Please let me know if you have any question

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
