Morgan lives in Austin, Texas, and lost his job when his company decided to reorganize. He had worked there for 3 years, and he
CaHeK987 [17]

Answer:

$455

Step-by-step explanation:

Minimum unemployment benefit in Texas is $69 per week and the maximum is $521.

In order to determine unemployment benefits in Texas, you must first calculate total earnings for the last quarter = 13 x $1,750 x 1/2 = $11,375

Now, you divide that amount by 25, so $11,375 / 25 = $455. Since that amount is below the maximum unemployment benefit per week, then Morgan is going to receive $455.

I really need help with this
BabaBlast [244]

Answer:

  • A  (-4, 1)
  • B  (2, 5)

Step-by-step explanation:

The current endpoints are ...

  V = (-9, 2)

  W = (-3, 6)

Put each of these in the translation formula to see where the image points are.

  (x, y) ⇒ (x+5, y-1)

  (-9, 2) ⇒ (-9+5), 2-1) = (-4, 1) . . . . point V ⇒ V'

  (-3, 6) ⇒ (-3+5, 6-1) = (2, 5) . . . . . point W ⇒ W'

The new end points are (-4, 1) and (2, 5), matching choices A and B.

Using the parallelogram pictured, find the length of the shorter diagonal. Round your answer to the nearest inch.
Tpy6a [65]

Answer:

21 in

Step-by-step explanation:

The law of cosines is helpful for this. The angle opposite the shorter diagonal is the supplement of the angle shown, so is 60°.

If we designate the known sides as "a" and "b", the short diagonal as "c" and the smaller angle as C, then the law of cosines tells us ...

c^2 = a^2 + b^2 -2ab·cos(C)

For the given dimensions, we have ...

c = √(15^2 +24^2 -2·15·24·cos(60°)) = √441 = 21 . . . inches
