A dish containing bacteria has a diameter of 0.0001 kilometer. The diameter of a bacterium is 10−16 kilometer. How many times la
Blizzard [7]

Answer:

100000000000 times

Step-by-step explanation:

Given

Diameter of Dish = 0.00001 km

Diameter of Bacterium = 10⁻¹⁶ km

Required

Determine the number of times the diameter of dish is bigger than that of the bacterium

<em>To solve this, we simply divide the diameter of dish by the diameter of the bacterium as follows</em>

<em></em>

Ratio = \frac{Dish}{Bacterium}

Ratio = \frac{0.00001}{10^{-16}}

Ratio = 100000000000

<em>Hence, the diameter of the dish is 100000000000 times larger than the diameter of the bacterium</em>

Question 3(Multiple Choice Worth 2 points)
Lilit [14]

The equivalent expression is seven-fifths squared times one-third cubed. Then the correct option is D.

<h3>What is an equivalent expression?</h3>

The equivalent is the expression that is in different forms but is equal to the same value.

Five-sevenths squared times one-third raised to the power of negative three all raised to the power of negative one.

Convert the sentence into numerical form.

\rm \rightarrow \left [ \left (\dfrac{5}{7} \right )^2 \times \left ( \dfrac{1}{3}\right )^{-3} \right ] ^{-1}

Simplify the expression, then we have

\rm \rightarrow \left [ \left (\dfrac{7}{5} \right )^{2} \times \left ( \dfrac{1}{3}\right )^{3} \right ]

The equivalent expression is seven-fifths squared times one-third cubed. Then the correct option is D.

More about the equivalent link is given below.
