works as a florist and worked 12 hours last week and earned $98. At that rate, how much will she earn this weekend if she works
kotykmax [81]

Answer:

$114.3

Step-by-step explanation:

Number of hours worked last week  = 12hrs

Amount earned for her work hours = $98

 The rate at which she earned =  ?

        Rate = \frac{amount earned }{total work hour}  

        Rate  = \frac{98}{12}    = $8.17/hr

Now;

Since the total hours she worked during the weekend  = 14hrs

  Amount earned  = $8.17/hr   x 14hrs   = $114.3

Find the value of x for which m parallel to n <br> A. 31 <br> B. 33 <br> C. 39 <br> D. 41
olya-2409 [2.1K]
Hello!

We are told that n and m are parallel.
The angle that measures 105 degrees is supplementary with the alternate interior angle of the angle which measures (3x - 18) degrees. Supplementary angles add to equal 180 degrees, so we can make an equation by first finding the measure of the alternate interior angle.

180 - 105 = 75

The alternate interior angle measures 75 degrees, so we can set that equal to 3x - 18 to solve for x since alternate interior angles are congruent.

75 = 3x - 18
93 = 3x
31 = x

Answer:
x = 31

Find all the zeros of the equation
lapo4ka [179]

Divide both sides by -3, and replace x^2 with y. Then

-3x^4+27x^2+1200=0\iff y^2-9y-400=0

Factorize the quadratic in y to get

y^2-9y-400=(y+16)(y-25)=0\implies y=-16,y=25

which in turn means

x^2=-16,x^2=25

But x^2\ge0 for all real x, so we can ignore the first solution. This leaves us with

x^2=25\implies x=\pm\sqrt{25}=\pm5

If we allow for any complex solution, then we can continue with the solution we ignored:

x^2=-16\implies x=\pm\sqrt{-16}=\pm i\sqrt{16}=\pm4i
