Answer:

12 remainder 3 (or 12.3)

Step-by-step explanation:

123/10=12.3

you can't really have .3 of a book, so 12 remainder 3 or three groups of 13 and 7 groups of 12.

Can someone answer this step by step to help me understand how to get my answer thank you

The answer is 19y – 9.

First, distribute the -3 to ( -4y + 3 ). So:
= ( 12y – 9 ) + 7y

Then, combine like terms. In this case, the like terms are 12y and 7y. So:
= 12y – 9 + 7y
= 19y – 9

Which two of the following are applications of the Logarithmic model? *

stellarik [79]

Question:

a. College GPA

b. Richter Scale

c. Acidity/Alkalinity

d. Compound Interest

e. Amortization Schedule

Answer:

The correct two options are;

b. Richter Scale

c. Acidity/Alkalinity

Step-by-step explanation:

Here we have

b. The Richter Scale, given by the following relation;

$M = log(\frac{I}{I_0} )$

M = Earth quake magnitude

I = Earthquake intensity

I₀ = Earthquake intensity of magnitude 0

Comparing two Earthquakes, A and B, we have

$M_A - M_B = log(\frac{I_A}{I_B} )$

c. Acidity/Alkalinity are determined by the pH of the solution, which is the negative logarithm of the hydrogen ion concentration

pH = -log₁₀ [H⁺].
