Option (B) describes the correct unique possibilities of the given triangle.
What are triangles?A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. △ABC is the designation for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a distinct triangle and a distinct plane. A triangle is a 3-sided polygon that is occasionally (though not frequently) referred to as the trigon. There are three sides and three angles in every triangle, some of which may be the same. Triangles can be divided into three types based on the lengths of their sides, and these are Scalene, Isosceles, and Equilateral.So, according to the given image:
We can easily observe that the triangle is an isosceles triangle with base angles being equal and the third angle being the smallest.Then, the correct option about the triangle will be an option (B).Therefore, option (B) describes the correct unique possibilities of the given triangle.

Each serving ofsalad dressing uses 3 tablespoons of olive oil and 1 tablespoon of vinegar. A tablespoon of olive oil costs $0.13 and a tablespoon of vinegar costs $0.04. What is the cost of x servings of dressing in dollars?
Answers
The cost of x servings of dressing in dollars will be $0.43x.
According to the question,
We have the following information:
Each serving of salad dressing uses 3 tablespoons of olive oil and 1 tablespoon of vinegar.
Cost of 1 tablespoon of olive oil = $0.13
Cost of 1 tablespoon of vinegar = $0.04
So,
The cost of each serving of salad = Cost of 3 tablespoons of olive oil + cost of 1 tablespoon of vinegar
The cost of each serving of salad = 3*0.13 + 0.04
The cost of each serving of salad = $(0.39+0.04)
The cost of each serving of salad = $0.43
Now,
The cost of x servings of salad = $0.43x
(Note that if we have to find the cost of more than 1 product than the number has to be multiplied with the cost of one product.)
Hence, the cost of x servings of salad dressing is $0.43x.

Calculations to show if Han and Tyler meet on the path within 1 hourThe following information is gotten from the question
Han and Tyler both started running toward each other from opposite ends of a 10-mile path
Han runs at a pace of 12 minutes per mile
Tyler runs at a pace of 15 minutes per mile
Distance covered by Han in 1 hour
12 minutes = 1 mile
60 minutes = ? miles
cross multiplying gives
? = 60 / 12
? = 5 miles
Distance covered by Tyler in 1 hour
15 minutes = 1 mile
60 minutes = ? miles

This means that Han covers 5 miles in and Tyler covers 4 miles, in a 10 mile distance.

The pre-tax subtotal was $171.00.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Given that:
After-tax total = $1,656.99
Tax rate in the area = 8.396%
The pre-tax price would be 100% and this tax rate is an addition.
Total percent = (100+8.396)% = 108.3%
Consider x be the pre-tax amount.
The total bill= (after-tax total) = (pre-tax subtotal) + 8.3% · (pre-tax subtotal)
(after-tax total) = (pre-tax subtotal) 108.3

Using the law of cosines, the missing angles are:

What is the Law of Cosines?The law of cosines is used to solve a triangle when given the lengths of the three sides of a triangle, and it is expressed by the formula:
c² = a² + b² - 2ab × Cos C.
Given the following:
a = 4 b = 5 c = 7Find C by substituting the values into the law of cosines formula:
7² = 4² + 5² - 2 × 4 × 5 × Cos C
49 = 16 + 25 - 40 × Cos C
49 = 41 - 40Cos C
49 - 41 = -40Cos C
8/-40 = Cos C
-0.2 = Cos C
C = Cos^(-1)(-0.2)
C = 101.5°
Find B using the Law of Sines:
sin B/b = sin C/c
Substitute
sin B/5 = sin 101.5/7
(sin B)(7) = (sin 101.5)(5)
sin B = (sin 101.5)(5)/7
sin B = 0.69995

Answers
The price per share after 5 hours is $28.32
The price per share after 23 hours is $-2.1
Given,
A company's stock began the day at $ 36.77per share.
and, price drops be $1.69 each hour.
To find the what is the price per share after 5hours
and, also find what will be after 23 hours rate continues?
Now, According to the question:
The price of the company's stock is initially at $36.77 per share. Each hour the price drops by $1.69. This condition can be modeled by the function:
P(t) = 36.77 - 1.69t
Where t is the time in hours.
The sign means the function is decreasing as time passes.
When t=5 hours, the price will be:
P(5) = 36.77 - 1.69 × 5 = 28.32
The price per share after 5 hours is $28.32
Now find the price when t=23 hours
P(23) = 36.77 - 1.69 × 23 = - 2.1
The price per share after 23 hours is $-2.1
Hence, The price per share after 5 hours is $28.32
