You have 5 people and 5 seats, so there can't be any empty seats
this means you have to calculate the permutations of 5 objects
5!=5*4*3*2*1=120
This exercise is false, can't be done.
Answer:
x = 3.5
Step-by-step explanation:
Since the triangles are similar we can use ratios to solve
4 7
------ = ------
(4+2) ( 7+x)
Using cross products
4(7+x) = 7*(4+2)
Distribute
28+4x = 42
Subtract 28 from each side
4x = 42-28
4x= 14
Divide by 4
4x/4 = 14/4
x = 7/2
X greater than or equal to 32 Fahrenheit when it is a liquid
