An atrium is being designed to house an exhibit of tropical birds. The atrium must enclose 250,000 cubic feet of space, and the designer wants it to have the shape of a hemisphere. Is such a design possible given that the plot of land on which it will be built is a rectangle 90 feet wide and 100 feet long?
The proposed design of the atrium (V < V') is possible since its volume is less than the maximum possible atrium.
Can this atrium be built in the rectangular plot of land?
The atrium with the maximum allowable radius (R), in feet, is represented in the image attached. The real atrium is possible if and only if the real radius (r) is less than the maximum allowable radius and therefore, the real volume (V), in cubic feet, must be less than than maximum possible volume (V'), in cubic feet.
First, we calculate the volume occupied by the maximum allowable radius:
V' = (8 · π / 3) · (45 ft)³
V' ≈ 763407.015 ft³
The proposed design of the atrium (V < V') is possible since its volume is less than the maximum possible atrium. [tex]\blacksquare[/tex]

The error is in step 2 in step 2 Susu forgot to divide 8 by 4 for finding the solution of a quadratic equation.
What is a quadratic equation?The name Quadratic comes from "quad" meaning square, because the variable gets squared (like x2). It is also called an "Equation of Degree 2"
Susu is solving the quadratic equation [tex]4x^2-8x-13=0[/tex] by completing the square
To apply to completing the square method we need to get x^2 alone
Susu added 13 on both sides. So step 1 is correct

Find the perimeter of each figure in feet, 48 in 3yd 5ft 1yd .
Answer:
Step-by-step explanation:
Remark
First of all, all the units must be the same. Inches is probably the best unit to use.
Second the base line at the bottom must be completed. How long is it
Givens
Left side = 48 inches
Top = 3 yards
1 yard is 36 inches.3 yard is 3* 36 = 108 inches.Right side = 5 feet.
1 foot = 12 inches5 feet = 12 * 5 = 60 inchesBottom = 1 yard + top
Bottom = 1 yard + 3 yards
Bottom = 4 yards
1 yard = 36 inches4 yards = 144 inchesPerimeter = 144 + 60 + 108 + 48
Perimeter = 360 Inches.
Answer
Perimeter = 360 inches
Perimeter = 360 / 12 = 30 feet There are 12 inches in a foot
Perimeter = 360 / 36 = 10 yards. There are 36 inches in a yard
The question does not specify the units. Probably inches would work, but if a computer is marking your answer and you get it wrong, you are going to have to try the other two answers in turn.

Find an equation for the line that passes through the points (6, -1) and (-6, 2).
Answer:
[tex]D : y = \frac{-1}{4}x + \frac{1}{2}[/tex]
Step-by-step explanation:
let D be the line that passes through the points (6, -1) and (-6, 2)
Then D has an equation of the form D: y = ax + b
Now we need to find a and b in order to be able to write the equation of the line D:
[tex]a = \frac{-1-2}{6-(-6)}= \frac{-3}{12}= \frac{-1}{4}[/tex]
Since the point (6 , -1) lies on the line D then :
-1 = (-1/4) × (6) + b
then
-1 = (-6/4) + b
then
b = -1 - (-6/4) = -1 + 6/4 = -4/6 + 6/4 = (-4+6)/4 = 2/4 = 1/2
then
b = 1/2
Conclusion:
Since a = -1/4 and b = 1/2 then
[tex]D : y = \frac{-1}{4}x + \frac{1}{2}[/tex]

A bag contains 6 blue marbles, 5 yellow marbles, 3 white marbles, and 1 red marble.
What is the probability of not selecting a white marble?
A. 2/3
B. 3/4
C. 4/5
D. 1/5
Please explain how you got the answer so I can learn
Any links and you will be reported please help
[tex]6 + 5 + 3 + 1 = 15 \: marbles[/tex]
Total number of possibilities excluding white marbles:[tex]6 + 5 + 1 = 12 \: marbles[/tex]
The probability of an event occuring is given by:[tex]p(a) = \frac{number \: of \: possibilities}{total \: number \: of \: possibilities} [/tex]
[tex]p(a) = \frac{12}{15} = \frac{4}{5} [/tex]
Letter CAnswer:
The total number of marbles in the bag is:
6 blue marbles + 5 yellow marbles + 3 white marbles + 1 red marble = 15 marbles
The probability of not selecting a white marble can be calculated as follows:
Number of non-white marbles / Total number of marbles
There are a total of 15 - 3 = 12 non-white marbles in the bag (6 blue marbles + 5 yellow marbles + 1 red marble).
So the probability of not selecting a white marble is:
12 / 15 = 4/5
Therefore, the answer is C) 4/5.

How can you decompose the composite figure to determine its area? as three triangles and a circle as two triangles, a rectangle, and a circle as a triangle, a pentagon, and a semicircle as a triangle, a rectangle, and a semicircle
We can decompose the composite figure into a triangle, a rectangle, and a semicircle in order to find the area of the composite figure.
What is the area?The space filled by a flat form or the surface of an item is known as the area.
The number of unit squares that cover the surface of a closed-form is the figure's area. Square centimeters and other similar units are used to measure area.
The area of the composite figure is equal to the sum of area 1, area 2, and area 3
Area 1 - triangle
Area 2 - rectangle
Area 3 - semicircle
We can decompose the composite figure into a triangle, a rectangle, and a semicircle in order to find the area of the composite figure.
