Hannah is asked to convert the number 0.305 to scientific notation. her answer is 3.05 × 106.
which statement best describes her answer?
hannah is correct.
hannah is not correct because the exponent should be 8.
hannah is not correct because 3.05 should be 3.5.
hannah is not correct because the exponent should be -6

Hannah is not correct because the exponent should be -6

Step-by-step explanation:

Hannah is asked to convert the number 0.00000305 to scientific notation. Her answer is 3.05 × 10^6

0.00000305 to scientific notation.

To get scientific notation we move the decimal point after the first number

so we move the decimal point 6 places to the right

It becomes 3.05

we moved the decimal point 6 places to the right so we put 10^-6

3.05 * 10^-6

Hannah is not correct because the exponent should be -6

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
