Answer:
A. 3 packs
B. $78.84
Step-by-step explanation:
A. Two bottles for each of 26 guests is a total of 2×26 = 52 bottles.
That many bottles will be found in 52/18 = 2 16/18 packs of bottles. Since Eliana cannot purchase partial packs, she will need to buy 3 packs of bottles.
__
B. Each pack costs $26.28, so the cost of 3 packs is 3×$26.28 = $78.84. Eliana will spend $78.84 on water for her guests.
Answer:
A. 7
Step-by-step explanation:
The problem is poorly specified, so <em>technically cannot be answered with a specific number</em>.
If we assume the "horizontal" lines are all parallel, then the one marked 21-x has a length that is the average of the other two:
(17 +11)/2 = 21 -x
14 = 21 -x
x = 21 -14 = 7
The value of x is 7.
_____
The attachment shows what happens when the lines are not parallel. The range of the midline lengths is from 3 to 14 for the segment lengths shown.
Divide the figure using vertical lines into 3 sub-areas. You have already done this on the left side of the figure. The base of this trapezoid is (30-10 -12) ft, or 8 ft. The trapezoid has 2 heights shown: one is 11 ft and the other is 15 ft.
The area of this trap. is [ (11 ft + 15 ft)/2 ] * [8 ft] ], or 13*8 ft^2, or 104 ft^2.
Next is the rectangle in the middle. Its height is 15 ft and its width is 12 ft. Its area is (15 ft)(12 ft) = 180 ft^2.
Last is the trapezoid on the right. Its base is 10 ft and the average of its heights is [(15+7.5) ft] / 2, or 11.25 ft. Thus, the area of this trap. is
(11.25 ft)(10 ft) = 112.5 ft^2.
Add these 3 sub-areas together to get the total area.
Good luck!!
