Robin says that polynomials are closed under division. Brad adamantly disagrees. Who is correct? Justify your answer.

Brad is correct.

Polynomials do not include negative exponents; this means there can be no variables in the denominator. If two polynomials do not divide evenly, the remainder is written as a fraction with the divisor (which can include a variable) in the denominator. This is not a polynomial.

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

$450 + 0.20x \ge 35y$

skelet666 [1.2K]

Answer:

The answer to the question is

1.5 hours that is;

When the distance between them is more then 135 miles is after 1.5 hours and they will lose radio contact at 3:30 p.m.

Step-by-step explanation:

We note that

The speed of the military convoy headed north =50 mph

The speed of the convoy headed south = 40 mph

Let t be the time taken for the two convoys to be 135 miles apart

The time taken for the two convoys to be 135 miles apart is given by

50×t miles+ 40×t miles= 135 miles

That is 90×t miles = 135 miles

t = 135/90 = 1.5 hrs

Cedric purchased a new refrigerator and stove at Home Depot for $3,729 on a deferred payment plan with no down

lesya [120]

Answer:

correct option is d. $242.81

Step-by-step explanation:

given data

APR = 25.5% = $\frac{25.5}{12}$ = 2.125

paid = $3,729

solution

we get here finance charge on the 1st month by multiplying 3,729 and now adding it to existing balance

so we get finance charge for the second and third months similarly as

APR ÷ 100 = $\frac{2.125 }{100}$ = 0.02125

so 1st

= $3,729 × 0.02125

= 79.25

and

$3,729 + $79.25 = $3808.24

so for next

= $3808.24 × 0.02125

= 80.93

and

$3808.24 + $80.93 = $3889.17

so for next

= $3889.17 × 0.02125

= 82.64

and

$3889.17 + $ 82.64 = $3971.81

finance charge = 3971.81 - 3729

finance charge = 242.81

so correct option is d. $242.81
