Answers
Answer: 93
Step-by-step explanation:
75+105+127= 307
307-250= 57
150-57= 93 (57 + 93 = 150)

a = -2, b = 6, c = 2
x = (- b + - sqrt(b^2-4ac))/(2a)
x=(-6+-sqrt(36-4*-2*2))/-4
x=(-6+-sqrt(36+16))/-4
x=(-6+-sqrt(52))/-4
x = (-6 +- 2sqrt13)/-4
x = (3 + - sqrt13)/2

cone. What is the expression for the volume of the pyramid in terms of the radius r of the cone?
base area for cone= B
base area for pyramid= B, 3r heigh
A. V = pi r³
B. V = 1/3 pi r²
C. V = 2 pi r²
D. V = 1/9 pi r³
E. V = 3 pi r³
Answers
The expression for the volume of the pyramid in terms of the radius r of the cone is . So, option A is correct.
The cone is a three-dimensional figure with a vertex and a flat base.
The volume of a pyramid is given by the formula:
Given that:
The base area of the pyramid = B
The height is 3r
The base area of the pyramid is the same as that of the cone.
The base of the cone =
The volume of the pyramid is calculated as:
V =
Therefore, the volume of the pyramid is . So, option A is correct.

Answer: the length of the rectangle is 100m and the breadth is 80m
Step-by-step explanation:
The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2(length + breadth)
Let the length of the initial rectangle be and the breadth of the initial rectangle be b
The perimeter of a rectangle is 360m. Therefore,
2(l + b) = 360
l + b = 180
If its length is decreased by 20 %, the new length would be l - 0.2l = 0.8l
its breadth is increased by 25%, the new breadth would be b + 0.25b = 1.25b
we get the same perimeter. Therefore
2(0.8l + 1.25b) = 360
0.8l + 1.25b = 180 - - - - - - - 1
Substituting l = 180 - b into equation 1,it becomes
0.8(180 - b) + 1.25b = 180
144 - 0.8b + 1.25b = 180
- 0.8b + 1.25b = 180 - 144
0.45b = 36
b = 36/0.45 = 80
Substituting b = 80 into l = 180 - b, it becomes
l = 180 - 80 = 100
