Answer: Choice C. a = 17, b = 6</h3>
Explanation:
A kite is any quadrilateral where we have two pairs of congruent consecutive sides (in contrast to a parallelogram where the opposite sides are congruent). Draw a segment connecting points G and J. Triangle GHJ is congruent to triangle GFJ. We'll use the fact that GH = GF, and also FJ = HJ
So,
GH = GF
2a-4 = 30
2a = 30+4
2a = 34
a = 34/2
a = 17
and
FJ = HJ
3b+6 = 24
3b = 24-6
3b = 18
b = 18/3
b = 6
Answer:
20 and 16
Step-by-step explanation:
Let us find x and y.
x – y = 4 _____(1)
x/2 + y/2= 18___(2)
Multiply (2) by 2 and add to (1)
x - y = 4
+<u>(x + y = 36)</u>
<u>2x = 40</u>
=> x = 40 / 2 = 20
From (1):
20 - y = 4
=> y = 20 - 4 = 16
The two numbers are 20 and 16.
Answer:
a) 560 (as you know)
Step-by-step explanation:
There are 7C3 = 35 ways to choose 3 full-time days from 7.
There are 2^4 = 16 ways to choose a half-day each day from the remaining 4 days.
The total number of possible schedules is ...
35×16 = 560
_____
nCk = n!/(k!(n-k)!)
7C3 = 7·6·5/(3·2·1) = 7·5 = 35
