Step-by-step explanation:
Given : Starks sculpture 30 cubed is a cube with sides 30 inches long.
We know that the volume of a cube is given by :-
Then , the volume of Starks sculpture 30 cubed will be :
Hence, the required volume =
Answer:
24.76 mine
Step-by-step explanation:
The first thing is to calculate the area of the region, which we can calculate since we have the density and the population. The area would be the quotient between population and density:
260000/135 = 1925.93
The area would be 1925.93 square mine
We know that the area is given by:
A = pi * r ^ 2
we solve to r
r ^ 2 = A / pi
r ^ 2 = 1925.92 / 3.14
r ^ 2 = 613.3
r = 24.76
the radius is equal to 24.76 mine
This is a relatively easy question to solve. You want to find 19.3% OF 126, meaning that you have to use multiplication. So you would do 126*0.193 which would equal 24.318 which can be rounded to 24.3
Step-by-step explanation:
=>x⁴-5x²+4
=>x⁴-x²-4x²+4
=>x²(x²-1)-4(x²-1)
=>(x²-1)(x²-4)
=>(x+1)(x-1)(x+2)(x-2)
hope this helps you.
Answer: Length = 12cm , width = 21cm
Step-by-step explanation:
Let the length be x , then the width is x + 9, That is
Length = x
Width = x + 9
The formula for calculating the perimeter of a rectangle is given by:
Perimeter = 2 ( Length + Width )
substituting the values , we have :
66 = 2 ( x + x + 9 )
66 = 2 ( 2x + 9 )
divide through by 2
66/2 = 2x + 9
33 = 2x + 9
subtract 9 from both sides
33 - 9 = 2x
24 = 2x
divide through by 2
therefore :
x = 12
This means that
Length = 12cm
Width = 12 + 9 = 21 cm
