Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The total gain for your investment in ravioli den is $700.
What is multiplication?Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
The cost of a single share was $45, while the number of shares where 100, therefore, the total cost of purchasing shares is:
Total Cost = $45×100 = $4,500
The selling price of a single share is $52, while the number of shares is the same, therefore, the total selling price is,
Total Selling Price = $52×100 = $5,200
The total gain for your investment in ravioli den is the difference between Total cost and total selling price. Therefore,
The total gain = $5,200 - $4,500 = $700
Hence, The total gain for your investment in ravioli den is $700.

Answers for this worksheet???
Answer:
1) C
2) D
3) 26
4) A
5) 68
6) Triangle MNL
Explanation:
1) C does not equal to 180. If you add up all the numbers it adds up to 169. Any triangle; interior adds up to 180.
2) When you minus 180 - 29.1 - 80 ; it equals to 70.9.
3) 180 - 32 - 122 = 26. You could also add 32 + 122; getting 154. Then 180 - 154.
4) We see a square box, meaning it's a right triangle. 180 - 90 - 42.7 = 47.3.
5) You can draw a picture to help you and see it visualize it. But it's the same process : 180 - 97 - 15 = 68
6) The whole triangle was 180. Equaling the whole as 108 was wrong.

It takes 13 hours and 15 minutes to paint longer walls of the houseStep-by-step explanation:
Given:Rectangular house. Painting of the longer walls takes 8 hours longer than painting shorter walls.Total time to paint is 18.5 hours.Let the length of shorter sides be x and longer sides be y.
Then we have the system:
y = x + 8x + y = 18.5Solve it by substitution:
x + x + 8 = 18.52x + 8 = 18.52x = 10.5x = 10.5/2x = 5.25Find the value of y:
y = 5.25 + 8 = 13.25 hours or 13 hours and 15 minutesShorter one be x
longer one=x+8

Step-by-step explanation:
As it is a second order equation, it means that it has two possible answers and they are [tex]x_1[/tex] and [tex]x_2[/tex].
The famous quadratic formula for solving any second order equation is the following:
[tex]x_{1} = \frac{-b + \sqrt{b^2 - 4 ac}}{2a}\\x_{2}=\frac{-b - \sqrt{b^2 - 4 ac}}{2a}[/tex]
Where a is the coefficient of [tex]x^2[/tex], b is the coefficient of x, and c is the free term. In other words,
[tex]a = 3\\b=4\\c=-2[/tex]
as the equation should be in the following form:
[tex]a x^2 + bx+c = 0[/tex]
Therefore the possible answer should be the following,
[tex]\frac{-4 + \sqrt{4^2 - 4*3*(-2)}}{2*3}=\frac{-4 +\sqrt{16 + 24}}{6} =\frac{-4 + \sqrt{40}}{6}=\\ \frac{-4 + \sqrt{4*10}}{6} = \frac{-4 + 2\sqrt{10}}{6}[/tex][tex]\frac{2*(-2 + \sqrt{10})}{2*3} = \frac{-2 + \sqrt{10}}{3}[/tex]

A quadrilateral has two angles that measure 200° and 110°. The other two angles are in a ratio of 2:3. What are the measures of those two angles?
Answer:
20° and 30°
Step-by-step explanation:
the sum of the 4 angles in a quadrilateral = 360°
given 2 angles are 200° and 110° , then remaining 2 angles sum to
360° - 200° - 110° = 360° - 310° = 50°
sum the parts of the ratio, 2 + 3 = 5 parts , then
1 part = 50° ÷ 5 = 10° , so
2 parts = 2 × 10° = 20°
3 parts = 3 × 10° = 30°
the two angles are 20° and 30°

wo containers designed to hold water are side by side, both in the shape of a cylinder. Container A has a radius of 12 feet and a height of 13 feet. Container B has a radius of 8 feet and a height of 16 feet. Container A is full of water and the water is pumped into Container B until Conainter B is completely full
The percentage of Container A that is full after the pumping is complete is; 45.3%
How to find the Volume of a Cylinder?
The formula for volume of a cylinder is;
V = πr²h
Volume of Cylinder A is;
V = π × 12² × 13
V = 1872π
Volume of Cylinder B is;
V = π × 8² × 16
V = 1024π
After pumping, volume in container A will be;
V_new = 1872π - 1024π
V_new = 848π
Percentage is;
848π/1872π * 100% = 45.3%
Thus, 45.3% of Container A is full after the pumping is complete.

Answer: It should look something like this.
Step-by-step explanation:
The graph of f(x) = (x + 3)(x - 2) is a parabolic function that is the product of two linear factors, (x + 3) and (x - 2).
The graph is given below.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
To understand the graph, we can begin by considering the x-intercepts, which are the points where the graph crosses the x-axis.
These occur where the value of f(x) is zero, which happens when either
x + 3 = 0 or x - 2 = 0.
So the x-intercepts are x = -3 and x = 2.
Next, we can consider the leading coefficient, which is 1 in this case.
Since the leading coefficient is positive, the parabola opens upward.
We can also find the vertex of the parabola by completing the square.
We have:
f(x) = x² + x(-2 + 3) - 2(-3)
f(x) = x² + x + 6
Now we can rewrite this in vertex form:
f(x) = (x + 1/2)² + 23/4
So the vertex is (-1/2, 23/4), which is a minimum point on the graph.
Thus,
We can sketch the graph of f(x) = (x + 3)(x - 2) as an upward-opening parabola that crosses the x-axis at -3 and 2 and has a minimum point at (-1/2, 23/4).

Given that XW bisects AXZ, what theorem or theorems could be used to justify that W is equidistant from the two outside rays?
Answer:
HA congruence postulate
Step-by-step explanation:
In order to show W is equidistant from A and Z, we must demonstrate that WA ≅ WZ. The HA congruence postulate can be used for that purpose.
__
proofWX bisects AXZ, so ∠WXA≅∠WXZ by the definition of an angle bisector. By the reflexive property of congruence, WX≅WX. The angles at A and Z are given as right angles.
So, we have triangles WAX and WZX that are right triangles with congruent hypotenuse and corresponding angle. These are the preconditions for the application of the HA congruence postulate. That postulate says the triangles WAX and WZX are congruent, so ...
WA ≅ WZ by CPCTC. Hence W is equidistant from the outside rays.
__
Additional comment
The definition of distance from a point to a line is the perpendicular distance from the point to the line. In this geometry, the perpendicular distances from W to the outside rays are the lengths of segments WA and WZ. That is why we need to show those lengths are the same.

The x-intercept of the function [tex]h(x) = 3 * \sqrt[3]{x - 5} +6[/tex] is -3
How to determine the x-intercept?The function is given as:
[tex]h(x) = 3 * \sqrt[3]{x - 5} +6[/tex]
The x-intercept is when h(x) =0.
So, we have:
[tex]3 * \sqrt[3]{x - 5} +6 = 0[/tex]
Subtract 6 from both sides
[tex]3 * \sqrt[3]{x - 5} = -6[/tex]
Divide both sides by 3
[tex]\sqrt[3]{x - 5} = -2[/tex]
Take the cube of both sides
x - 5 = -8
Add 5 to both sides
x = -3
