Answer:
45 handshakes
Step-by-step explanation:
If there are n persons and each person shakes every other person hand once then the total number of handshakes are
Now, it has been given that 10 people meet, and each person shakes every other person's hand once.
Therefore, n = 10.
Hence, from the above mentioned formula, we have
Total number of handshakes =
Hence, total 45 handshakes were occurred.
36 = 2t + u
A. t = 10, u = 16
B. t = 10, u = 4
C. t = 14, u = 20
D. t = 16, u = 22
ƒ -1(4) =
Answer:
f-1(x)=x-4
f-1(4)=0
Step-by-step explanation:
to get an inverse function, replace x with y, and y with x.
y=x+4 ---> x=y+4
solve for y: x=y+4 --> y=x-4 --> f-1(x)=x-4
f-1(4)=(4)-4=0
we are given
original fare =360
new fare =270
now, we can find decrease in fare
decrease in fare = original fare - new fare
so, we can plug value
decrease in fare = 360-270
decrease in fare =90
now, we can find percentage decrease in fare
