Step-by-step explanation:
Given : There are 10 people in the party .
To Find: Assuming all 10 people at the party each shake hands with every other person (but not themselves, obviously) exactly once, how many handshakes take place?
Solution:
We are given that there are 10 people in the party
No. of people involved in one handshake = 2
To find the no. of possible handshakes between 10 people we will use combination over here
Formula : 
n = 10
r= 2
Substitute the values in the formula
No. of possible handshakes are 45
Hence The no. of possible handshakes takes place are 45.
Answer:
1
Step-by-step explanation:
Eliminate parentheses using the distributive property.
= -4i +1/4 -5i +3/4 -8i +17i
= (1/4 +3/4) +i(-4 -5 -8 +17)
= 1 + 0i
= 1
Answer:
w(-4.2) = 3(-4.2) -1 = -12.6 - 1 = -13.6

The w(-4.2) is your t so you substitute it in your expression which means you get 3(-4.2) -1 and that gives you -13.6.
Answer:
22.
Step-by-step explanation:
"Plug and chug" .75 multiplied by different numbers, up until you get to 16.5 as an answer. 22 is what you multiply it by, so that is correct.
Well 3 feet=1 yard
so the conversion factor is 3ft/1yd
so 12 yards converted to feet is
12yd times 3ft/1yd
the yd will cancel and you will be left with 36 feet
each banner is 1 foot so 36/1=36
she can make 36 banners
