A circular plate has a diameter of 9 inches. What is the area of the plate? Explain the steps you follow to get to your answer
Answers
Answer:
The area of the circular plate is: " 63.59 in² " .
______________________________________________________
Note:
______________________________________________
diameter, "d" = 9 in. (given).
radius, "r" = "d/ 2 " = "(9 inches) / 2 " = 4.5 in.
______________________________________________
Area of a circle, "A" :
A = * r² ;
in which: "A = Area of circle ("plate"); in units of "square inches"; or "in² " ;
" = 3.14 " {approximation we shall use} ;
"r = radius = 4.5 in." ;
________________________________________________________
Plug in our known values to solve for the area, "A" :
A = (3.14) * (4.5 in)² ;
A = (3.14) * (4.5)² * (in²) ;
A = (3.14) * (4.5) * (4.5) * (in²) ;
A = 63.585 in² ; round to: " 63.59 in² " .

bobby spent 40% of his allowance on art supplies last month, with two-thirds of this amount spent on paintbrushes alone. if his monthly allowance is $75, how much did bobby spend on paintbrushes last month?
Answers
Bobby spent $20 out of $75 of his monthly allowance on paintbrushes.
What is monthly allowance?
Giving someone money on a regular basis to help them pay for the things they need is known as giving them an allowance.
Main Body:
total monthly allowance = $75
Now Bobby spent 40% on his art supplies,
which means we need to calculate 40% of 75.
⇒(40/100)*75
⇒30
so Bobby spent $30 on art supplies.
now according to question,
Bobby spent 2/3 on paintbrushes
⇒2/3 of art supplies
⇒(2/3 )*30
⇒$20
Hence Bobby spent $20 on his paintbrushes.

Answers
The width of the sidewalk is 1.155.
What is a rectangle?A rectangle is a type of parallelogram having equal diagonals.
All the interior angles of a rectangle are equal to the right angle.
The diagonals of a rectangle do not bisect each other.
Given that,
The dimension of the rectangular garden is 8 x 6.
The surface of the new garden is 1/6 th of the original one.
Suppose the width of the side walk is x.
Then, the dimensions of the sidewalk is given as (8 - 2x) x (6 - 2x).
As per the question the following equation can be written for the area of new garden,
(8 - 2x) x (6 - 2x) = (1/6) (8 x 6)
=> 48 - 4x²- 30x = 8
=> 4x² + 30x - 40 = 0
Solve the above quadratic equation to get,
x = -8.655, 1.155
Since the width cannot be negative, the value of x is taken as 1.155.
Hence, the width of the sidewalk of the new garden is 1.155m.

A. 80 miles per hour
B. 75 miles per hour
C 65 miles per hour
D 61 miles per hour
Answers
Answer: 61 miles per hour.
Step-by-step explanation:
The median is the number that's placed in the middle when the given numbers are either arranged in the ascending it the descending order.
In this case we are already given the speed of the cars as 65, 66, 63, 56, 56 50, 85, 61, 73, 81. We will therefore arrange them in ascending order and this will be:
50, 56, 56, 61, 63, 65, 66, 73, 81, 85.
To change the median speed of
the cars to 63 miles per hour, the 6th number when arranged in ascending order has to be 63. Therefore, in thus case, we will need a speed lessee than 63 miles pee hour. Therefore, option D is the answer.
When we re-arrange with the new speed included. This will be:
50, 56, 56, 61, 63, 63, 65, 66, 73, 81, 85.
Therefore, we can see that the median is 63.

What is the volume of an oblique cone with a radius of 9cm and a height of 16cm
Answers
The volume of the oblique cone is approximately 1,017.88 cubic cm.
What exactly is a cone?
A cone is a three-dimensional geometric shape that tapers smoothly from a flat, circular base to a single point called the apex or vertex. The base can be any shape, but a circular or elliptical base is most common.
A cone has several important properties, including its height, which is the distance from the vertex to the base, and its radius, which is the distance from the center of the base to any point on the base. Another important property of a cone is its slant height, which is the distance from the vertex to any point on the edge of the base.
Now,
The formula for the volume of a cone is given by:
V = (1/3)πr²h
where V is the volume, r is the radius, and h is the height.
However, in the case of an oblique cone, the height is measured along a line that is not perpendicular to the base of the cone. To calculate the volume of an oblique cone, we need to use the slant height, which is the distance from the vertex of the cone to any point on the base, as well as the radius and height.
The slant height of an oblique cone can be calculated using the Pythagorean theorem:
l = √(r² + h²)
where l is the slant height.
Substituting the given values, we get:
l = √(9² + 16²)
l = √(81 + 256)
l = √337
l ≈ 18.3576
Now,
V = (1/3)πr²h
Substituting the given values, we get:
V = (1/3)π(9²)(16)
V ≈ 1,017.88 cm³
Therefore, the volume of the oblique cone is approximately 1,017.88 cm³.

What is the profit at the optimal solution?
Group of answer choices
The model becomes unbounded
$500
$800
Alternate optimal solutions exist
Answers
The given linear program can be solved using the simplex algorithm. The optimal solution is obtained by setting up the initial tableau and applying the simplex method. The optimal solution is x=100, y=0, and the maximum profit is $500. This means that the company should produce 100 units of x to maximize their profit, subject to the given constraints.
The given linear program is a maximization problem with three constraints. To solve this problem, we can use the simplex method, which involves converting the constraints to equations and setting up the initial tableau. The initial tableau for this problem is:
| Basic Variables | x | y | s1 | s2 | s3 | RHS |
|-----------------|---|---|----|----|----|-----|
| z | 5 | 10| 0 | 0 | 0 | 0 |
| s1 | 1 | 0 | 1 | 0 | 0 | 100 |
| s2 | 0 | 1 | 0 | 1 | 0 | 80 |
| s3 | 2 | 4 | 0 | 0 | 1 | 400 |
We can see that the basic variables are s1, s2, and s3, and the non-basic variables are x and y. We can choose the most negative coefficient in the objective row, which is -5 for x, and pivot on the corresponding element in the tableau, which is 1 in the first row and first column. This results in the following tableau:
| Basic Variables | x | y | s1 | s2 | s3 | RHS |
|-----------------|----|-----|-----|-----|------|-------|
| z | 0 | 10 | -5 | 0 | 0 | 500 |
| s1 | 1 | 0 | 1 | 0 | 0 | 100 |
| s2 | 0 | 1 | 0 | 1 | 0 | 80 |
| s3 | 0 | 4 | -2 | 0 | 1 | 200 |
Now the basic variables are x, s2, and s3, and the non-basic variables are y and s1. We can see that the objective function has improved from 0 to 500, and the most negative coefficient in the objective row is now 0. We can conclude that the optimal solution has been reached, and it is x=100, y=0, with a maximum profit of $500.
Bn
The optimal solution to the given linear program is x=100, y=0, with a maximum profit of $500. This means that the company should produce 100 units of x to maximize their profit, subject to the given constraints. We can use the simplex method to solve linear programs like this one, by setting up the initial tableau and applying the pivot operations to improve the objective function. If the problem has multiple optimal solutions or is unbounded, we need to use additional techniques to determine the appropriate solution.

What is the solution to √ x-1 = √x-1 ?
Answers
The solution to √x-1 = √x-1 is all real numbers.
To solve the equation √x-1 = √x-1, let's start by isolating one of the square roots. We can square both sides of the equation to eliminate the square roots:
(√x-1)² = (√x-1)²
Expanding both sides:
x - 2√x + 1 = x - 2√x + 1
We can observe that the equation simplifies to 1 = 1. This equation is true for all real numbers since any number minus itself equals zero. Therefore, there is no restriction on the value of x, and the solution is all real numbers.
