Answer:
Well I’m not sure what you want but I’ll give you both,
The perimeter is 25 units
The area is 28.5 units ^2
Step-by-step explanation:
Well to find perimeter just count every unit which is what I did and got 25 units.
To find the area jsut split them into two shapes and find the area for both.
Triangle formula: bh/2
Rectangle: Lw
Well we have 3 for base and 3 for height.
3*3=9
9/2=4.5
4.5 is the triangle
We got 3 for width and 8 for length
3*8=24
24 is the rectangle
Add them up
24+4.5= 28.5
28.5 units
The straight line equals 180
The two angels have to equal 180
180-63=117
117-25=92
92 divided by 4 is 23
x=23
I hope this helped!
well add -6y to 6y which equals 0 then add 8y to 6y which equals 14y
now you have 13.02=14y
now you can divide 13.02 divided into 14 which equals 0.93
0.93 = y
Answer:
This is an Exponential Decay
Step-by-step explanation:
A = 1200(0.85)⁶
The above expression is an Exponential Decay because 0.85 is less than 1
The formula for Exponential Decay
= y = a (1 - r)^t
We equate both equation together
Where
a = 1200
1 - r = 0.85
t = 6
Solving for r
1 - r = 0.85
r = 1 - 0.85
r = 0.15
Converting to Percentage
r = 15% decay rate
