Answer:
<h2>D) 25,000</h2>
Step-by-step explanation:
The best estimation of the total number of people at the concert is the quotient between the total area of the arena, and the area that each person occupies.
So, we need to find the area of each person.
We know that each person took up a circular space with a diameter of 0.9m. The radio would be
And the circular are would be
Now, we divide the area of the arena by the area per person
Where represents the number of people at the concert.
Therefore, the nearest estimation is D. 25,000 people are at the concert.
Answer:
13 hours and 5 minutes is right
Well, there's nothing to solve per se, however assuming you meant "rationalizing the denominator", which means namely to "get rid of that pesky radical at the bottom", then
<span>Write an equation for the line
perpendicular to y = 2x - 5 that contains (-9,6).
---
The given line has slope = 2
Any line perpendicular to it must have slope = (-1/2)
----
Form:
y = mx + b
Solve for "b":
6 = (-1/2)(-9) + b
6 = (9/2) + b
b = 3/2
----------------
Equation:
y = (-1/2)x + (3/2)</span>
