Answer:

4*10^-5

Step-by-step explanation:

  • Start by counting the zeros to the right of the decimal if 0<x<1. Stop when you hit a digit between 1 and 9
  • Add 1 to the number of zeros
  • This is the power
  • Express the number as one between 1 and 9
  • The power is changed to a negative, if 0<x<1

0.00004 has 4 zeros. Add 1 = 5

The power on 10 becomes negative (-5)

4 is a number between 1 and 9 inclusive.

4 * 10^-5

Given:

The given table represents the ingredient need to make 4 muffins.

To find:

The amount of flour needed to make 12 muffins.

Solution:

We have, the data for 4 muffins.

From the given table it is clear that,

Flour need for 4 muffins = 250 g

Flour need for 1 muffins = \dfrac{250}{4} g

Flour need for 12 muffins = \dfrac{250}{4}\times 12 g

                                          = 250\times 3 g

                                          = 750 g

So, 750 g flour is need to make 12 muffins.

Therefore, the correct option is D.
