Answer:
The total of ways the buildings can be painted are = 4 3 2 2 1 = 48 ways.
Step-by-step explanation:
i) color five buildings that are in a row.
ii) any two neighboring buildings must be different colors
iii) the first third and fifth buildings must be different colors.
iv) the number of ways to paint the fist building are 4.
v) the number of ways to paint the second building are 3.
vi) the number of ways to paint the third building are 2.
vii) the number of ways to paint the fourth building are 2.
viii) the number of ways to paint the last building are 1.
ix) therefore the total of ways the buildings can be painted are
= 4 3 2 2 1 = 48 ways.
50% is exactly half, so to find half of something you just divide it by 2= 7.5
Or you could multiply it
15 x 0.50=7.5
Answer:
y= x -1.25
Step-by-step explanation:
Use slope= y2-y1/x2-x1
(13.75, 12.50), (3.25 , 2.00)
12.50 -2.00/ 13.75 -3.25
10.50/ 10.50
slope= 1
Substitute into y=mx+b
12.50= 1(13.75) +b
b= -1.25
y= x -1.25
J - 65
If you meant 65 is less than j than it'd be
65 < j
