Answer:
8%
Step-by-step explanation:
let,
this year population of students (pt)= 195
last year population of students (p)= 210
time(t)= 1 year
Population Change( R)= ?
we have,
pt= p( 1 - R/100)^t
195 = 210 ( 1 - R/100)^1
0.92= 1 - R/100
0.92-1= R/100
- 0.08 = - R/100
R= 0.08×100
R= 8%
The correct answer is:
A) 5x + 15
Explanation:
5x is the area of the green square (5•x)
15 is the area of the orange rectangle (5 •3 =15)
To have the total area you have to sum the areas of the two figures: 5x + 15
4.05 in a mixed number is 4 1/2
