Refer to the figure shown below.
Quadrilaterals ABCD and EFGH are similar.
The shortest side (the 4th side) of quadrilateral ABCD is AD = x.
The three longest sides are
AB = 24, BC = 16 and CD = 12 feet.
The corresponding shortest sides of quadrilateral EFGH are
EH = 9, and GH = 18 feet.
Because the two quadrilaterals are similar, therefore
Answer: The length of the 4th side of quad ABCD is 6 feet.
Answer:
Option C: 126
Step-by-step explanation:
Total displays to be assembled = 280
25% of the displays are assembled during the first hour, this value becomes:
Remaining displays =
40% of the remaining displays during the second hour, the value becomes:
Hence, number of displays that will not have been assembled by the end of the second hour =
Therefore, the answer is 126.
Using the quadratic formula, you can solve this quite easily.,,,,
a b c
x² - 12x + 59 = 0 a(1)...b(-12).....c(59)
(-b +/- √b² - 4ac) / (2a) (substitute the values for a, b, and c)
(-(-12) +/- √ (-12)² - 4 (1) (59)) / 2(1)
(12 +/- √-92) / 2 ( √-92 can be written as √-1√4√23)
(12 +/- √-1√4√23) / 2 (√-1 = i and √4 = 2)
6 +/- 23i
D=distance traveled one way
t=d/s
d/20 + d/30 = 12
3d+2d=60(20)
5d=720
d=720/5 = 144 mi one way
144/20 = 7.2 hrs at 20 mph
144/30 = 4.8 hrs at 30 mph
