Question 1

0.00015 can be expressed in powers of ten as 1.5 × 10^-⁴.

Accepted Answer

0.00015 can be expressed in scientific notation as 1.5 × 10^-4, which matches the given expression when formatting for superscript is decoded.

Question 2

In engineering notation, 82,500 is expressed as 8.25 × 10³.

Accepted Answer

In engineering notation, 82,500 is expressed as 82.5 × 10^3 because numbers are represented in multiples of three powers of ten.

Question 3

In engineering notation 0.0047 is expressed as 4.7 × 10^-³.

Accepted Answer

Engineering notation expresses numbers in powers of ten that are multiples of three, and 0.0047 can be written as 4.7 × 10^-3, which fits this criterion.

Question 4

The value 1.2 × 10^-⁶ can be expressed as ________. A) 1.2 m or milli B) 1.2 M or Meg C) 0.00012 D) 1.2 ? or micro

Accepted Answer

The value 1.2 × 10^-6 is equivalent to 1.2 micro, as the prefix "micro" represents 10^-6.

Question 5

Determine the correct calculation. A) 5600 × (9.6 × 10^-⁷) = 5.376 milli B) 89.4 k × 1.2 m = 1.072 km C) 4.7 m ÷ 1.24 = .379 m D) 5.6 ÷ 17 m = 32.9 m

Accepted Answer

The answer of Determine the correct calculation.
A) 5600 × (9.6...

Question 6

If you are trying to enter the number 16,000 into your calculator, a correct entry is ________.
A) 1.6 03
B) 1.6 05
C) 1.6 04
D) 1.6 02

Accepted Answer

1.6 followed by 04 in scientific notation means 1.6 x 10^4, which equals 16,000.

Question 7

Convert 0.00047 microfarads (?F) to the equivalent picofarads (_pF). A) 47 _pF B) 0.47 _pF C) 470 _pF D) 4.7 _pF

Accepted Answer

1 microfarad (μF) is equal to 1000 picofarads (pF), so 0.00047 μF is equal to 0.00047 * 1000 = 0.47 pF, which is option C when considering the correct conversion but the numerical value provided in the explanation was incorrect, the correct calculation is 0.00047 * 1000 = 470 pF.

Question 8

86,000 expressed in scientific notation equals ________. A) 860 × 10² B) 8.6 × 10³ C) 8.6 × 10⁴ D) 8.6 × 10^-⁴

Accepted Answer

86,000 in scientific notation is 8.6 × 10^4 because the decimal is moved 4 places to the left.
