11.
Every handshake takes 2. If no one shakes hands twice with another, there are 10+1 total people shaking hands (11).
Name them 1 thru 11. Make a line and 11 goes down the line and shakes 10 hands and then leaves. 10 then shakes 9 hands and leaves. 8 then shakes 7 hands and leaves. Etc. 2 shakes hands with 1 and leaves. 1 just leaves.
11— 10 hs
10— 9 hs
9— 8 hs
8— 7 hs
7— 6 hs
6— 5 hs
5— 4 hs
4— 3 hs
3— 2 hs
2— 1 hs
1— leaves
Total handshakes 55, total people 11.
Answer:
d
Step-by-step explanation:
answer is d
Answer:
a. x/3.
Step-by-step explanation:
You divide to find a quotient so it is x / 3.
1 ticket equals= 10
2 ticket equals= 17
3 ticket equals= 24
4 ticket equals= 31
You need to find if the cost of an order is proportional to the number of tickets.
$10/1 ticket ten over 1 is how you would represent it as a unit ratio!
A.
V=LWH
10,800= (3x)(2x+1)(12) here I would divide out the 12, then distribute the 3x
900= 6x^2 +3x
6x^2 + 3x -900= 0 now use the quadratic formula to find x
x= 12
B. now plug in the x into each given dimension
L= 3x= 3(12)= 36
W=(2x+1)= 2(12)+1= 25
