Kelly could buy 4 people the chicken salad, and two people the egg salad. The reason for this is that 4 x $5= $20 and 2 x $4= $8. So, when you add together the total price: $20+$8= $28; which is the exact amount of money she is willing to spend. This answer also fulfils the fact that more coworkers want chicken salad.
Step-by-step explanation:
TPC and DPC are supplementary angles so
DPC=180-123=57°
Fill the 5-liter container, pour water from that into the 3 liter container until that is full, You will now have 2 liters left in the 5 liter container.
Empty the 3-liter container, and then transfer the 2 liters from the 5-liter container into it.
Now fill the 5-liter container again, then pour water carefully from the 5-liter container into the 3-liter container until it is full - exactly one more liter.
The 5-liter container now has 4 liters in it.
It is a little blurry but you should be able to see it.
Secant is a trigonometric function that quantifies the quotient of hypotenuse and the side that is adjacent to the given angle. This is the reciprocal of the cosine function.
cosine = adjacent / hypotenuse = x/h
secant = h / x
Secant equal to -1 means that x and h are numerically equal but opposite in sign.
secant = -1
cosine = 1/secant =1/-1 = -1
arccos (-1) = 180°
Thus, the answer to this item is 180°.
