Answer:

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%

Answer:

$20096 ft^2$

Step-by-step explanation:

We are given that

Length of rope=l=160 feet

Radius of quadrant of circle=r=160 feet

We have to find the maximum grazing area of the cow.

We know that

Area of quadrant of circle= $\frac{1}{4}\pi r^2$

Where $\pi=3.14$

Using the formula

Area grazed by cow= $\frac{1}{4}\times 3.14(160)^2$

Area grazed by cow= $20096 ft^2$

Answer:

3000000000

Step-by-step explanation:

Dividing 9*10^7 by 3, we have 3*10^7

Same with 3*10^-2 so we have

(3*10^7)/(1/100) which is equal to 3*10^7*100 which is equal to 3000000000
