Answer:
Three
Step-by-step explanation:
If you are talking about earth there are three layers.The dense,hot inner core ,the molten outer core,the mantle and the thin crust.
5/30=1/6
4/6=2/3
1/6+2/3= (1+4)/6=5/6
or, without simplifying:
5/30+4/6= (5+20)/30=25/30= 5/6
What 3D figure/shape is it?
Length = 5x
width = x
area = 125
A = L*W
125 = (5x)(x)
125 = 5x^2
125/5 = x^2
25 = x^2
sqrt{25} = sqrt{x^2}
5 = x
The width is 5 feet.
The length is 5 times 5 feet or 25 feet.
To find the perimeter, we use P = 2L + 2W.
P = 2(25) + 2(5)
P = 50 + 10
P = 60 feet.
Done!
Answer:
15,831.957504
Step-by-step explanation:
30,000*.88=26400
26400*.88=23232
23232*.88= 20,444.16
20,444.16*.88= 17,990.8608
17,990.8608*.88= 15,831.957504
