Width = x
Length = 3x
Perimeter = x + x + 3x + 3x = 8x
He walked 3 rounds
3 x 8x = 24x
Total distance walked = 5280 feet
24x = 5280
x = 220
Shortest side is 220 feet
Answers:
- a = 475
- r = -0.5
- f(3) = 59.4
=======================================================
Explanation:
Any exponential function is of the form y = a*b^x
Comparing that to y = 475*(0.5)^x, we see that a = 475 and b = 0.5
Set b equal to 1+r and solve for r
1+r = 0.5
r = 0.5-1
r = -0.5
The negative r value tells us that the growth rate is -50%, in other words, we have a 50% decay rate. The amount drops by 50% each time x goes up by 1. This is the same as saying the amount cuts in half each time x goes up by 1.
-----------------------
Lastly, plug in x = 3 to find f(3)
f(x) = 475(0.5)^x
f(3) = 475(0.5)^3
f(3) = 59.375
f(3) = 59.4

Answer:
3 = 12
Step-by-step explanation:
Given:
Lou had r rocks in his collection.
He separated his rocks into 3 equal piles.
He now has 12 rocks in each pile.
<u>Question asked:</u>
Which equation represents this situation?
<u>Solution:</u>
Total number of rocks =
He separated in number of piles = 3
Each pile contains = 12 rocks
The equation will be :-
3 = 12
Therefore, equation which represents this situation is 3 = 12
