Answer:

C

Step-by-step explanation:

Cost in location A: 2n-4-2n^2

Cost in location B: \dfrac{5}{4}n-\dfrac{6}{5}n^2-\dfrac{11}{3}

Combined cost: (2n-4-2n^2)+\left(\dfrac{5}{4}n-\dfrac{6}{5}n^2-\dfrac{11}{3}\right)

Add these two polynomials. Combine the like terms:

\left(2n+\dfrac{5}{4}n\right)+\left(-2n^2-\dfrac{6}{5}n^2\right)+\left(-4-\dfrac{11}{3}\right)\\ \\=\dfrac{13}{4}n-\dfrac{16}{5}n^2-\dfrac{23}{3}\\ \\=-\dfrac{16}{5}n^2+\dfrac{13}{4}n-\dfrac{23}{3}

Komok [63]

Answer:

Minor earthquakes occurred in the country in the last​ year were<u> 2326</u>.

Step-by-step explanation:

Given:

In the last​ year, a total of 2727 earthquakes occurred in the country.

Of​ these, 85.3 % were minor tremors with magnitudes of 3.9 or less on the Richter scale.

Now, to find the minor earthquakes occured in the country last year.

<em>Total earthquakes occurred in the country = 2727.</em>

<em>The percent of minor earthquakes = 85.3%</em>.

Now, to get the number of minor earthquakes:

85.3% of 2727.

=\frac{85.3}{100} \times 2727.

=\frac{232613.1}{100}

=2326.131

<em>The number of minor earthquakes nearest whole number = 2326.</em>

Therefore, minor earthquakes occurred in the country in the last​ year were 2326.
