The value of the angle ∠2 = 32° using angle bisector.
What is angle bisector?
In geometry, the ray, line, or segment that divides a given angle into two equal pieces is known as the angle bisector. For instance, a 60-degree angle will be split into two angles of 30 degrees each by an angle bisector. It splits one angle into two smaller congruent angles, to put it another way.
An angle in a triangle is divided into two equal or congruent angles by a straight line known as the angle bisector. Each triangle can have one angle bisector for each of its three vertices. The intersection of these three angle bisectors in a triangle is referred to as the triangle's incenter.
The given angle ∠XVW = 64°
VP is a bisector,
So the angle ∠XVW will be divided equally.
So ∠2 = 32°
Hence the angle of the bisector ∠2 = 32°.

What is Binomial Distribution?
Binomial distribution is a discrete type probability distribution whose probability mass function is

Answers
The height of the large boxes is 36 inches when the volume of box is 3456 cubic inches.
According to the question,
We have the following information:
A cereal company packs cereal boxes into large cardboard boxes. The large boxes are 12 inches long and 8 inches wide.
Volume of box = 3456 cubic inches
We know that the box is in the shape of cuboid.
Following formula is used to find the volume of cuboid:
Volume = length*width*height
12*8*height = 3456
96*height = 3456
Dividing both sides by 96:
Height = 3456/96
Height of the box = 36 inches

The interior angles of the triangle are 43°, 43° and 94°. The exterior angle of the triangle is 86°.
How to find interior and exterior angles of a triangle?A triangle is polygon with three sides. The sum of angles in a triangle is 180 degrees.
The triangle above is an isosceles triangle. The base angles of a triangle is congruent.
Therefore, the base angles are 5x - 12 and 5x -12.
The sum of the remote interior angles is equal to the opposite exterior angles.
5x - 12 + 5x - 12 = 8x - 2
10x - 24 = 8x - 2
10x - 8x = -2 + 24
2x = 22
x = 22 / 2
x = 11
Therefore,
5x - 12 = 5(11) - 12 = 43°

Write an inequality that represents the condition based on the number of hours the company wants to spend.
Answers
Step-by-step explanation:
The first thing we need to do is to identify the characteristics of this problem. As you can see, this situation has restriction, limitations on how much money and time they can spend.
In mathematics, restrictions are expressed with inequalities, because it gives us the power to express in terms of more or less than something. When we have this inequality-restrictions problems, it's very helpful to organise all info, so according to the problem, we have:
$ hr
Candidates (x) 400 20
Employees (y) 3600 120
Max. 95000 470
We this organisation, we can easily find expressions, the important thing here is to put together similar variables, money with money and time with time.
So, you can see that, the maximum money they can spend is 95000, and the maximum time is 470 hours, which give us:
As you can see, for money inequality, we used (less than), and for hours we used ''less or equal than''. This difference is because in the text it says that they has less than 95000 (not equal than 95000), and for hours they have at most 470 (meaning that this is a maximum, 470 and below that number).
Therefore, those two inequality express the restriction about money and time limitations for candidates and employees.

Each month payment = $200
Each month actual payment = $225
The percentage prediction is off by.
= (225 - 200)/225 x 100
= 25/225 x 100

Given,
Your parent promises to make you a smoothie using the blender while you're mowing the lawn. The blender makes a sound that is 88 decibels
Here we need to find the intensity of the sound of the blender
In order to find the intensity, we have to do the following steps,
First, we have to divide the decibel level by 10.
=> 88/10 = 10/10 log (x / 1 x 10⁻¹²)
Now, we have to use that value as the exponent of the ratio.
=> 8.8 = log (x / 1 x 10⁻¹²)
Finally, we have to use that power of ten to find the intensity in Watts per square meter.
