Say her hourly pay was $p for the day shift and $1.2p for the night shift.
(1) x = 55. Clearly insufficient: we need to know how these 55 hours are split between the day shift hours and the night shift hour.
(2) Grace's gross pay for the hours she worked on day shift last month was exactly 50% of her total gross pay for last month. Not sufficient.
(1)+(2) Say Grace worked h hours on the day shift and 55-h hours on the night shift. Thus, her pay for the the hours she worked on day shift is $ph and the total gross pay is $ph+(55-h)*1.2p. From (2) we have that ph=0.5(ph+(55-h)*1.2p) --> reduce by p: h=0.5(h+(55-h)*1.2). We have 1 variable, so we can solve for it. Sufficient.
Answer: C.
Answer:
I'm not sure what your asking, but, no, all rectangles are parallelograms.
I found this over the internet, and I hope it helps you understand why a rectangle is always a parallelogram, but a parallelogram is not always a rectangle:
It is true that every rectangle is a parallelogram, but it is not true that every parallelogram is not a rectangle. For instance, take a square. It's a parallelogram — it is a quadrilateral with two pairs of parallel faces. But it is also a rectangle — it is a quadrilateral with four right angles.
For 10 feet and 6 inches,
12 inches = 1 foot, therefore 6 inches = 6/12 foot = 0.5 foot
10 feet 6 inches = 10 + 0.5 = 10.5 feet
7 feet required 3 pints
1 foot would have required (3/7) pints
10.5 feet will then require: (3/7)*10.5 = 4.5 pints.
Therefore 10 feet and 6 inches will require 4.5 pints.
There are a total of 10 marbles. Out of those 2 are yellow.
So, the probability of picking a yellow marble is 2/10, or 1/5 simplified.
As a percentage, this is 20%
Hope this helps :)
