the answer is F/0.15 and 100/15 F
BECAUSE
15%
F ⋅100%
= 0.15
F
⋅1
The first partner in the handshake can be any one of 15 people.
The second partner can be any one of 14 people.
So the total number of possible arrangements is (15 x 14) = <u>210</u> .
<em><u>BUT . . . .</u></em>
If Mr. Smith and Mr. Jones are shaking hands, it doesn't matter which one is the first partner and which one is the second partner ... It's the same handshake either way.
That number of ' <u>210</u> ' up above counted both ways separately. The real number of handshakes <em>between different people</em> is half of that 210/2 = <em>105 handshakes</em>.
Answer:
(-1, 1)
Step-by-step explanation:
I used a graphing tool to graph the equations. When graphed, they cross at coordinate (-1, 1). Therefore, (-1, 1) is the solution.
5x - 25 + 3x + 9 = 180
8x - 16 = 180
8x = 196
x = 24.5
Answer:
y-1=5(x-3)
Step-by-step explanation:
y=mx+b where m=slope and b=y-intercept,
y-y1=m(x-x1)
y-1=5(x-3)
