<h3>Answer:</h3>
3/4 mile
<h3>Explanation:</h3>
Area is the product of length and width. Put the given values into that formula and solve for width.
... A = L·W
... (1/2 mi²) = (2/3 mi)·W
... (1/2 mi²)/(2/3 mi) = W = (1/2)·(3/2) mi
... W = 3/4 mi
Answer:
The 20th day
Step-by-step explanation:
On the first day, number of people who know the secret=2
Number of people On the second day =2X2=4
Number of people On the third day =4X2=8
We can see that on each passing day, the number keeps doubling.
This is an example of a geometric progression.
Now we are to determine the number of days when the number of people who know the secret will grow past 1,000,000
For the G.P. 2,4,8,...
a=2, common ratio, r= 2
Uₙ=arⁿ⁻¹
arⁿ⁻¹>1000000
2X2ⁿ⁻¹>1000000
2ⁿ⁻¹⁺¹>1000000
2ⁿ>1000000<2²⁰=1048576
2ⁿ<2²⁰
n<20
It means on the 20th day, more than 1 million people will have been told the secret
