Question 6

What scientific value for n will make this equation true?(4.8 × 10–3)(n) = 9.6 × 109

Revolt · Accepted Answer

2.0 × 1012

Question 7

What conclusions can be drawn about finding the quotient in scientific notation? Check all that apply.

Revolt · Accepted Answer

The exponent of the solution is –12, the difference of the original exponents.; The coefficient of the solution must be greater than or equal to one but less than 10.; The quotient is 3.0 × 10-12

Question 8

Find the quotient of 2.5 × 10-3 and 7.1 × 106. What can be concluded about the solution? Check all that apply.

Revolt · Accepted Answer

The E indicates that the solution is given in scientific notation.; The coefficient is 3.5211.; The solution can be written in scientific notation as 3.5211 × 10-10.

Question 9

Analyze Nick’s solution. Is he correct? If not, what was his mistake?

Revolt · Accepted Answer

No, the power multiplied to 8.64 should have an exponent of 0.

Question 10

How can Buster tell without fully performing the calculations?

Revolt · Accepted Answer

Buster can tell the answer is less than 1, because he can subtract the exponents to see that the solution will have an exponent of –5.
