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
Binomial,since there are 2 terms and the degree is 3 since that is the highest exponent
Answer:
tax = $6.63
Step-by-step explanation:
We can find the tax by multiplying the original amount by the tax rate.
tax rate = 10 % = .1
tax = 66.30 * .10
= 6.63
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:

We make use of the following representation:
weekly sales from cars.
hours worked in a week
His weekly salary is then calculated as:
Salary (S) = Earnings per week + Commission * Sales from car
So, we have:

Express percentage as decimal


Assume he works for y hours in a week.
His hourly rate is:
--- i.e. weekly salary divided by number of hours

For this rate to be at least
, the following condition must be true
--- i.e. is hourly rate must be greater than or equal 35
So, we have:

Multiply both sides by y

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 ×
) + 32 = 50°F
x°C = 50 - 32 = 18
x°C = 18
x°C =
× 18 = 10°C
So 50°F is equal to 10°C.
