Answer:
Number on ants on Earth = 1.2 × 10¹⁵
Step-by-step explanation:
1 quintillion = 10¹⁸ or (1000000000000000000)
∴ 12 quintillion = 12 × 10¹⁸
12 quintillion = 10,000 × Number of ants on Earth
Let the number of ants on Earth = n
12 quintillion = 10,000 × n
dividing both sides by 10,000
12 quintillion ÷ 10,000 = n

Number on ants on Earth = 1.2 × 10¹⁵
If you plot the points given on a coordinate plane you see that this is a hyperbola that is is horizontal in nature, meaning it opens side to side, not up and down. We can determine the center of it by taking the point equidistant from the vertices, which is (4, 5), the h and k of our center, respectively. Also, the equation looks like this when it is horizontal:

. a is the distance between the center and the vertices, so our a = 2, and c is the distance between the center and the foci, so our c = 3. We need to find b now, using Pythagorean's theorem.

and

. Now we have everything we need to rewrite the equation:

So those two consecutive whole numbers will be 6 and 7.
Answer:
80/160
Step-by-step explanation:
so basically...
50 is half of 100
so then you look at it and your like welp if its half then ur going to have to do half for 80
so 80 x 2= 160
and for A can you please show the options or at least tell me
Answer:
He gets 42 visitors 4 weeks after starting to build his website.
He gets 10 new visitors per week.
Step-by-step explanation:
Equation for the number of visitors:
The equation for the number of visitors Timmy's new website receives after t weeks is:

In which b is the number of visitors rightly after he starts.
Timmy is building a new website. Right after he starts, he has 2 visitors.
This means that
, so:

How many visitors does he get 4 weeks after starting to build his website?
This is v(4). So

He gets 42 visitors 4 weeks after starting to build his website.
How any new visitors does he get per week?
After 0 weeks:

After 1 week:

2 weeks:
After 2 week:

22 - 12 = 12 - 2 = 10
He gets 10 new visitors per week.
