4 1/4 means 17/4
17/4*8=34
In this item, we are to determine the number of high fives given considering that there are 12 total number of participants in the meeting. We know for a fact that each high five will require 2 participants. We can determine the answer to this item by using the concept of Combination.
Combination of 12 taken 2 can be expressed as 12C2 and can be solved using the equation,
n = (12!)/(2!)(12 - 2)!
This expression is equal to 66. Hence, the answer to this item is 66 high fives.
F(-2)=8-10*(-2)=28
g(-2)=5(-2)+4=-6
fg(-2)=168
50.24
Circumference = pi*d
P=3.14 d=16
Answer:
x = 17 and y = 10
Step-by-step explanation:
ABCD is a parallelogram
So AB = CD and AD = BC
so
3x - 9 = 42
3x = 51
x = 17
and
4y - 3 = 37
4y = 40
y = 10
Answer
x = 17 and y = 10
