315pounds/week * 1week/37.5hr = 8.4pounds/hr

Look at the units. The weeks will cancel out and you will get hours. With the problems the best way to solve them is by thinking of unit cancellation.

total = (# of hours) * (hourly rate)

divide each side by # of hours

315 divided by 37 1/2 = 8.4

She gets 8.40 per hour

Organize the following polynomial expressions from least to greatest based on their degree:
Mumz [18]

Answer:

Step-by-step explanation:

We have to organize the given polynomials from the least to greatest based on their degrees.

A). x + 2xyz

Here xyz = x^{1}y^{1}z^{1}

Power of x is = 1

Power of y = 1

and power of z = 1

So degree of (x + xyz) will be degree of the highest degree term = 1 + 1 + 1 = 3

B). 9x³y²

Degree of this term = power of x + power of y = 3 + 2 = 5

C). 18x²+ 5ab - 6y

Degree of the polynomial = Highest degree of the variable x = 2

D). 4x^{4}+3x^{2}-x-4

Degree of highest degree term 4x^{4} = 4

So sequence of the polynomials based on their degrees will be

C - A - D - B [From lowest to highest]

Find the 64th term of the arithmetic sequence -4, -21, -38, ...−4,−21,−38,
lisov135 [29]

a_{n} = a_{1} + d(n - 1)  ; a₁ is the first term, d is the difference between terms, and n is the term

-4, -21, -38, ...   ⇒   a₁ = -4, d = -17

a_{n} = -4 - 17(n - 1)

   = -4 - 17n + 17

   = 13 - 17n

a_{64} = 13 - 17(64)

    = 13 - 1088

    = 1075

Answer: 1075
