Answer:

Option C.

Step-by-step explanation:

Two beauticians Lydia and Jackie are working on your hair.

Lydia takes the time to complete the work = 2 hours

Per hour work done by Lydia = 1/2

Jackie complete the  work = 1 hour

In one hour total work done by both Jackie and Lydia together = 1+\frac{1}{2}=1\frac{1}{2}or \frac{3}{2}

therefore, time taken by both to complete the work will be = \frac{1}{\frac{3}{2} } = \frac{2}{3}

Option C. two thirds is the correct option.

Answer:

  1.728×10¹⁵

Step-by-step explanation:

You may recall from 3rd grade that multiplying by 10 adds a zero to the right of a number (moves the decimal point 1 place to the right).

An exponent is used to signify repeated multiplication. These facts together are used to translate to/from scientific notation.

  10 = 1 × 10

  100 = 1 × 10 × 10 = 1 × 10²

__

Continuing in like fashion, 5.4×10⁸ represents 5.4 × (1 followed by 8 zeros).

Similarly, 3.2×10⁶ = 3.2 × (1 followed by 6 zeros)

The product will be ...

  (5.4×10⁸)×(3.2×10⁶) = (5.4×3.2) × (1 followed by 8+6 = 14 zeros)

  = 17.28 × 10¹⁴

  = (1.728 × 10) × 10¹⁴ . . . moving the decimal point so there's 1 digit to its left

Adding that extra zero into the count we already have, this becomes ...

  = 1.728×10¹⁵

_____

<em>Additional comment</em>

Your scientific or graphing calculator will have a mode for showing numbers in scientific notation. You can enter these numbers directly into your calculator and have it show you the result in scientific notation.

Or, you can use a spreadsheet with appropriate output cell formatting.
