Answer:
Ok so...
Mean: 68.76
Median: 72
Range: 85
Step-by-step explanation:
Assume that the length of the rectangle is "l" and that the width is "w".
We are given that:
(1) The length is one more than twice the base. This means that:
l = 2w + 1 .......> equation I
(2) The perimeter is 92 cm. This means that:
92 = 2(l+w) ...........> equation II
Substitute with equation I in equation II to get the width as follows:
92 = 2(l+w)
92 = 2(2w+1+w)
92/2 = 3w + 1
46 = 3w + 1
3w = 46-1 = 45
w = 45/3
w = 15
Substitute with w in equation I to get the length as follows:
l = 2w + 1
l = 2(15) + 1
l = 30 + 1 = 31
Based on the above calculations:
length of base = 31 cm
width of base = 15 cm

Answer:
I think it should be 
Step-by-step explanation:
When the question said area of the cube, I think it was supposed to be surface area, which would
where a is the length of one edge. Given that the length of one edge is 2x, we would plug in 2x to the equation to get
which would become
.
Answer:
side length of sculpture = 9 cm
height of sculpture = 6cm
Step-by-step explanation:
Given that,
volume of sculpture = 162cm³
side length of sculpture = x
height of sculpture = x-3
formula for volume of sculpture
<h3>V=1/3 a²h</h3>
by putting values, the equation can be used to find the length of the sculpture’s base
162 = 1/3 (x)² (x-3)
162(3) = (x)² (x-3)
486 = x²(x-3)
486 = x³ - 3x²
x³ - 3x² - 486 = 0
x = 9 <em>(using a graph tool / calculator equation mode)</em>
side length of sculpture = 9 cm
height of sculpture = 9 - 3
= 6cm
