The answer is A i hope this help
3 people know a fact in 1st day.
In 2nd day they share it with 3 people each=3×3
Now 3×3 people shares it with 3 people each. and so on...
So,
3+3²+3³+3⁴+3^5+3^6+3^7
=3279 no of people altogether , will hear from 1st day to 7th day...
On the day 7,no of people who will hear the fact=3^7=2187
Divide y by x:
150/10 = 15
135/9 = 15
30 /2 = 15
They all equal 15
This means the constant of proportionality would be y = 15x
The answer is C.
Answer:
62.83 
Step-by-step explanation:
The equation is V(Volume) equals π (Pi/3.14) multiplied by r(radius) squared multiplied by h(height). The way it would be written out is V=π×
×h. So when you plug in the radius (2) and the height (5) you get π×
×5 which equals 62.83185 or 62.83. I hope this helps you understand and if you need more help let me know.
67 multiplied by 3 is 201, so there is 201 people in the age group 12-29. Also, 67% is approximately two thirds, and we can see that reflected in our answer.
