Ah this kind of question is great! There's a strange and lovely relationship between repeating decimals and constants divided by 9 (or 99 or 999). An explanatory example is ".777777..." which can actually be expressed as 7/9. And ".09090909..." can be expressed as 09/99 or 1/11.

Devon made a scale drawing of a triangle. He used a scale factor of 1/4 to draw the new triangle. How does each side of the new
Charra [1.4K]
The answer is Option A.
Scale Factors
If the Scale Factor IS 1, the polygon stays the SAME.
(If an equilateral triangle has a side length of 8 and the scale factor is 1, the sides will stay at 8)
If the Scale Factor is MORE THAN 1, the polygon's sides INCREASE depending on what the scale factor is.
(If a square has a side length of 3 and the scale factor is 4, the sides will increase to 12)
If the Scale Factor is LESS THAN 1, the polygon's sides DECREASE depending on what the scale factor is.
(If a square has a side length of 5 and the scale factor is 1/2, the side lengths will decrease down to 0.5)
Therefore each side length of the new triangle is 4 times shorter than the original (Option A)

Answer:

B. 4 \times 10^{12}

Step-by-step explanation:

(6 \times 10^{8}) \div (1.5 \times 10^{-4}) =

= \dfrac{6 \times 10^{8}}{1.5 \times 10^{-4}}

= \dfrac{6}{1.5} \times \dfrac{10^{8}}{10^{-4}}

= 4 \times 10^{8 - (-4)}

= 4 \times 10^{12}
