Answer:
Part 1: 114,570,685 people
Part 2: The population grew by 2.5% (1,722,862 people)
Step-by-step explanation: For part 1 you would multiply 100,236,820 by 1.143 because of the fact that your percentage is increasing. so the 1 before the decimal point stands for 100% of the starting number and the .143 stands for the 14.3% that the population is increasing by.
Part 2 you would divide 53,594,378 by 55,317,240 to get approximately .975. .975 shows that 53,594,378 is about 97.5% of 55,317,240. You then subtract the numbers 100 and 97.5 to get 2.5. 2.5 is the percentage that the population is increasing by. So, then you could just subtract 55,317,240 and 53,594,378 to get 1,722,862. This is the amount of people the population increased by. Then you just put your answer that the population increased. That it increased by 2.5% and 2.5%= 1,722,862 people
I hope this helps you :)
Answer:
30
Step-by-step explanation:
90+2x+x=180
3x=90
x=30
The area of a dodecagon is 1/2aP
where:
a-apothem
P-perimeter
In the figure you will draw a point to any side and make a line perpendicular from a center to that side. Then if u think u can see that with only one draw of a hypotenuse can form a triangle. Then after drawing the hypotenuse which has 2 triangles, make the top angle of 1 triangle there are 30 degrees. On the down part is perpendicular and the left or the right is the 60 degrees. After that using special right triangles like the 30, 60, 90,. Then at the base of the one it bisected dived them by 2 for the 2 triangle's base. After that solve using it since the radius is 14. The apothem is 14(sqrt of 3). So after solving them the perimeter of each dodecagon is 12 sided so 14x12 is 168
A=1/2aP
A=1/2(14)(sqrt of 3)(168)
A=1176(sqrt of 3)
Thats the area of the dodecagon now the circle
A=(pi)r^2
A=(pi)(9)^2
A=81pi
Therefore the color purple is greater than the color green
Answer:
Just divide the numbers by 10 and then multiply the quotient by 2. hope this helped
