There is a total of 90 handshakes.
<h3>
How many handshakes took place?</h3>
There are 5 sets of triplets.
If we select one of the sets, each of the triplets will have one handshake with the other 12 people. So we have 36 handshakes at this point.
Now we only care for the other 4 sets.
We select one set again, each triple on that set will have one handshake with the other 9 people, so for the 3 triplets, we have a total of 27 new handshakes.
For the remaining 3 sets we do the same, this time we add 18 handshakes.
Finally, there are 2 sets of triplets, this time we add 9 new handshakes.
To get the total number of handshakes we need to add them all:
36 + 27 + 18 + 9 = 90
There is a total of 90 handshakes.

Answer:
1. The
is between 3 and 4.
2. The
is between 7 and 8.
3. The
is between 4 and 5.
4. The
is between 9 and 10.
5. The
is between 6 and 7.
Step-by-step explanation:
1.
: 10 is near the perfect squares 9 and 16, which would mean its answer is between their square roots which are 3 and 4.
2.
: 10 is near the perfect squares 49 and 64, which would mean its answer is between their square roots which are 7 and 8.
3.
: 10 is near the perfect squares 16 and 25, which would mean its answer is between their square roots which are 4 and 5.
4.
: 10 is near the perfect squares 81 and 100, which would mean its answer is between their square roots which are 9 and 10.
5.
: 10 is near the perfect squares 36 and 49, which would mean its answer is between their square roots which are 6 and 7.
Answer:
y=6,95x+35
Step-by-step explanation:
