Tcecarenko [31]

Answer:

3( root 3 /2)^2 + 3/4 (root 3 )^2 - 2(2/ root 3) ^2 - 3/4 (1/root3)^2

= 3 ×3 /4 + 3 × 3 /4 - 2 ×4 /3 - 3/4 × 1/3

= 9/4 + 9/4 -8/ 3 - 1/4

= 9/4 + 9/4 - 1/4 - 8/3

= 17/4 - 8/3

=( 17 × 3 - 8 × 4 )/12

= (54 -32)/12

= 19 /12

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

kherson [118]

Answer:

10°C

Step-by-step explanation:

The temperature is 50°F

Let's assume that 50°F = x°C

The formula is;

(x°C × \frac{9}{5}) + 32 = 50°F

\frac{9}{5}x°C = 50 - 32 = 18

\frac{9}{5}x°C = 18

x°C = \frac{5}{9} × 18 = 10°C

So 50°F is equal to 10°C.
