given
no. of student went to the first school dance = 340
no. of student went to the last school dance = 306
Percentage of change between two dance
= ((no. of student went to the first school dance - no. of student went to the last school dance)/ no. of student went to the fist school dance)*100
= (340 - 306)/340 *100
= (36/340 )*100 = 10.59%
The percent of change between the two dances 10.59%.
The formula of an area of a square: 
a - side
We have: 
substitute:
The fromula of a perimeter of a square is: 
substitute:
Answer:
A = 9pi
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
We know the diameter
r = d/2 = 6/2 = 3
A = pi (3)^2
A = 9pi
(5x-7) + (3x-4) + (2x-6)
5x-7+3x-4+2x-6
10x-17.
The answer might be like this:
50 x 12 = 600
*because of 1 year = 12 months
so the answer is 600 months
