A parking lot has sixty-one parking spaces numbered from 1 to 61. There are no cars in the parking lot when Jillian pulls in and

Nutka1998 [239]

Answer:

B. 40/61

Step-by-step explanation:

There are 40 spots out of the 61 in the lot with numbers greater than or equal to 22. The probability of choosing one of them at random is 40/61.

_____

About the answer choices

61/21 and 61/40 are both numbers that are greater than 1. A probability is always a number between 0 and 1 (inclusive), so these answers can be rejected immediately.

There are 21 spots with numbers less than 22, so 21/61 is the probability of choosing one of those. That is not what the question is asking for.

Mahmoud earns $450 per week plus a 20% commission as a car salesman. He wants his

frosja888 [35]

The complete question implies that we define an inequality that represents the relationship between the number of hours worked in a week and the weekly sales

The inequality that relates the number of hours to the weekly sales is:

$450 + 0.20x \ge 35y$

We make use of the following representation:

$x \to$ weekly sales from cars.

$y \to$ hours worked in a week

His weekly salary is then calculated as:

Salary (S) = Earnings per week + Commission * Sales from car

So, we have:

$S = 450 + 20\% * x$

Express percentage as decimal

$S = 450 + 0.20* x$

$S = 450 + 0.20x$

Assume he works for y hours in a week.

His hourly rate is:

$Hourly = \frac{S}{y}$ --- i.e. weekly salary divided by number of hours

$Hourly = \frac{450 + 0.20x}{y}$

For this rate to be at least $\$35$ , the following condition must be true

$Hourly \ge 35$ --- i.e. is hourly rate must be greater than or equal 35

So, we have:

$\frac{450 + 0.20x}{y} \ge 35$

Multiply both sides by y

$450 + 0.20x \ge 35y$

Answer:

Step-by-step explanation:

$\frac{12x}{2x-3x-10}-\frac{x}{x-5}=\frac{12x}{-x-10}-\frac{x}{x-5}\\\\=\frac{12x}{-(x+10)}-\frac{x}{x-5}\\\\=\frac{-12x}{x+10}-\frac{x}{x-5}\\\\=\frac{-12x*(x-5)}{(x+10)*(x-5)}-\frac{x*(x+10)}{(x-5(x+10)}\\\\=\frac{-12x*x-5*(-12x)}{(x+10)(x-5)}-\frac{x*x+x*10}{(x-5)(x+10)}\\\\=\frac{-12x^{2}+60x}{(x+10)(x-5)}-\frac{x^{2}+10x}{(x-5)(x+10)}\\\\=\frac{-12x^{2}+60x-(x^{2}+10x)}{(x+10)(x-5)}\\\\=\frac{-12x^{2} + 60x - x^{2}-10x}{x^{2}+5x-50}\\\\=\frac{-13x^{2}+50x}{x^{2}+5x-50}$
