Answer:
Step-by-step explanation:
because i know math isn't wrong Hope this helps XD lol
Polygon area = n*side length^2 / [4*tan(180/n)]
side length^2 = polygon area * [4*tan(180/n)] / n
where n is the number of sides
side length^2 = 55 sq inches * (4*tan(180/6)) / 6
side length^2 = 55 sq inches * 4 * tan (30) / 6
side length^2 = (55 sq inches * 4 * 0.57735) / 6
side length^2 =

<span>
<span>
127.017
</span>
</span>
</span>
/ 6
side length^2 =
<span>
<span>
<span>
21.1695
</span>
</span>
</span>
side length = square root (
<span>
<span>
<span>
21.1695

)
side length =

X+y+z = 132
x = 7+z
y = 3z
(7+z)+3z+z = 132
5z = 132-7
z = 125/5
z = 25 <=====
x = 7+z
x = 7 + 25
x = 39 <=====
y = 3z
y = 3 × 25
y = 75 <=====
hope it helps :)
I am not 100% positive but think it is c
For this case we have a function of the form:
y = A (b) ^ x
Where,
A: initial amount
b: decrease rate
x: time
We have then:
b = 0.15
Therefore the percentage of decrease is:
(1-0.15) * 100 = 75%
Answer:
75%
option 3
