Because one side of the square is 8 (4*2), we know that the square's area is 64.
Now, we basically find the circle's area:
A=πr2 = 50.27
64 - 50.27 = 13.73
The area of the shaded region is 13.73
where P is the population t years after 1st January 2010.
The graph below shows the growth of the population.
a) Write down the coordinates of
the point a.
b)
How many mice were on the
island on January 1st 2010?
C)
To the nearest whole number,
how many mice were on the
island on 1st January 2014?
a) The coordinates of point a are (t, 0).
b) There were 40 mice on the island on January 1st, 2010.
c) Rounding to the nearest wholenumber, there were approximately 92 mice on the island on January 1st, 2014.
a) To find the coordinates of point a on the graph, we need to look at the intersection of the curve with the x-axis (time axis). Since point a is on the x-axis, its y-coordinate (population) is 0. Note that the x-coordinate (t) represents the time in years.
b) To find the population of mice on January 1st, 2010 (t = 0 years), we can substitute t = 0 into the population equation:
So, there were 40 mice on the island on January1st, 2010.
c) To find the population on January 1st, 2014 (t = 4 years), we can again substitute t = 4 into the population equation:
Rounding to the nearest whole number, there were approximately 92 mice on the island on January 1st, 2014.

Hope it help mate✌
25 points to 50 points is a 100% change
100% of 25 = 25
25 + 25 = 50
100% is your answer
hope this helps
YES!! :)
both 6 and 48 are divisible by 6, the greatest common factor.
so you divide both 6 and 48 by 6....
6÷6=1
48÷6=8
Your simplified fraction is now 1/8
(3,750 people
60%=did shop
40%=did not shop =2,500
2,500/40 = x/100
40x = 2,500x100
40x=250,000
x = 250,000/40
x=6,250
6,250 =all people at the mall
6,250 - 2,500 =3,750 (60%)
OR
(2,500 x60)/40 = 3,750
Answer:
3750
Step-by-step explanation:
2500 is 40% of 6250. 6250 - 2500 = 3750 or 60% of the people.
