You need to DIVIDE the 3/4 meter into 1/3 meter pieces, so....
(3/4)÷(1/3) = (3/4) *(3/1) = (9/4) = 2.25
She can cut 2 (1/3) meter pieces.
To find what is left subtract (2/3) from the original (3/4).
(3/4)-(2/3)= (1/12) meter
Answer:469 million
Step-by-step explanation:
Given
The population of a country at t=1900 is 420 million
and P'(t) is a constant therefore P(t) is a linear function of time
assuming P(t)=7t +c
at t=0 i.e. 1900 at starting Point P(t)=420 million
i.e.


Thus 

Thus at 1907 Population is 469 million
P'(t)=7 indicates that growth rate of Population is constant equals to 7 billion
Hi dear,
use this formula:
y - y1= m(x-x1)
Y1 = -3
X1 = 0
m = 4
y-(-3)=4(x-0)
y+3=4x
y=4x-3
