Answer:

d. about 50 times larger

Step-by-step explanation:

The given expressions for magnitude (M) can be solved for the intensity (I). Then the ratio of intensities is ...

$\dfrac{I_2}{I_1}=\dfrac{I_0\cdot 10^{M_2}}{I_0\cdot 10^{M_1}}=10^{M_2-M_1}=10^{4.2-2.5}\\\\=10^{1.7}\approx 50$

The larger earthquake had about 50 times the intensity of the smaller one.

A chemist is using 351 millimeters of a solution of acid and water. If 18.2% of the solution is acid, how many milliliters of ac

Zolol [24]

Answer:

The % of of acid in solution = 63.88 ml

Step-by-step explanation:

The solution of acid and water = 351 milliliters

The % of of acid in solution = 18.2% of 351 ml

Or, The % of of acid in solution = $\frac{18.2}{100}$ × 351 ml

Or, The % of of acid in solution = 63.882 ml

Hence ,The % of of acid in solution = 63.88 ml Answer

When making a guess and retesting this information, a theory or <u>model</u> may be formed which explains why something has occurred or what it may look like. Models are a representation of a certain situations that has occurred. These models can provide and amplify a clearer perception and comprehension of how and what processes are involved in an occurred phenomenon. And by that said, it can change and be modified depending on which factor catalyzed the alterations. </span>

What is the smallest rotation clockwise about the center of the figure that will carry the entire figure onto itself.

postnew [5]

Step-by-step explanation:

A regular n-sided polygon has n axes of symmetry. The angle between two consecutive axes is 360° / n.

In the case of an octagon, the angle is 360° / 8 = 45°.
