And DVD cost $26.75 before sale tax sale tax is 7.5% what is the total of cost of DVDs

blondinia [14]

First let's convert 7.5% into a decimal by doing Beyoncé on it and move the decimal two places to the left.

$7.5\% = 0.075$

Now let's multiply the cost of the DVD by the converted percent,

$26.75 \times 0.075 = 2.00$
Now let's add the above number to the original price, remember, $2 is not exact.

$26.75 + 2.00 = 28.75$

Assume that the growth rate of a population of ants is proportional to the size of the population at each instant of time. Suppo

Nutka1998 [239]

(1/A) dA/dt= C where A is the population of ants and C is a constant
ln(A) = C*t + C1 where C1 is another constant that comes out of integration and t is time in days.
Plugging in: at t=0, A= 100 so C1 = ln(100) = 4.605
at t=3, A=230 so ln(230) = 3*C +4.605 so C = 0.278
Final equation:
ln(A) = 0.278t + 4.605
or:
A = exp(0.278t + 4.605)
After 14 days, A = exp(0.278*14 + 4.605) = 4875.2

What is the solution of the system of linear equations below?

Kipish [7]

Answer:

A is the correct answer

Step-by-step explanation:

To get the fastest answer for these kind of questions, you just have to apply (0, -2) into either one of the 2 equations:

2 * 0 - 6 * (-2) = 12

0 - (-12) =12

0 + 12 = 12 (TRUE)

So the solution will be (0, -2)
