Answer:
Answer in explanation
Step-by-step explanation:
In this question, we would be examining the validity of some statements on the number π(pi)
π Is a whole number?
This is wrong, π is a fraction of 22 to 7 parts I.e 22/7
π Is double the radius?
This is wrong. It is the diameter that is double the radius
π Is approximately 3.14?
This is correct to an extent. The actual value in decimal is around 3.142857142857143 which makes the 3.14 somehow correct
π represents the ratio of the circumference of the circle to the diameter?
This is correct.
Mathematically, circumference C = π * diameter D
Hence C/D = π
π Is approximately 22/7?
This is correct. This is the ratio used for π
Answer:
The answer to your question is 7.8 mi
Step-by-step explanation:
Data
H (4,3)
G (10, 8)
Process
1.- Use the distance between to points formula to find the distance
dHG = 
x1 = 4 y1 = 3
x2 = 10 y2 = 8
2.- Substitution
dHG = 
3.- Simplification
dHG = 
dHG = 
dHG = 
4.- Result
dHG = 7.8 mi
Answer:
The year 1996
With population of both 21600
Step-by-step explanation:
From 1990 to 2000 = 10 years
So city A grew from 12000 to 28000 that is city A had an increase of 16000 in 10 years.
While city b grew from 18000 to 24000 , that's an increase of 6000 in 10 years to.
For city A
10 years= 16000
1 year = 16000/10
1 year = 1600
For city B
10 years = 6000
1 year = 6000/10
1 year = 600
So we are to find what year the both cities had same population.
12000 + x1600 = y
18000 + x600 = y
X is the year difference
Y is the population at that year
Eliminating y gives
6000= x1000
X= 6
If x is 6
18000+3600= y
21600= y
So 6 years + 1990 = 1996
