In the given triangle the measure of ∠Q is (B) 73.5°.
What is a triangle?A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. Triangle 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.So, let's use the Sine rule in the calculation as follows:
q/sin q = r/sin r15/sin q = 12/sin 50.1 (Cross multiply)12 × sin q = 15 × sin 50.1 (divide both sides by 12)sin q = 15 sin 50.1/12q = sin⁻¹(15 sin 50.1/12) ≈ 73.5° (Rounded off)Therefore, in the given triangle the measure of ∠Q is (B) 73.5°.

Robert mixed 1 1 3 liters of blue paint with 1 2 3 liters of red paint to make 3 liters of purple paint. To make a new batch of purple paint he used 2 liters of red paint. Using the same ratio, Robert should use Response area liters of blue paint . brainly
Answers
Answer: Hence, [tex]1\dfrac35[/tex] liters of blue paint have been used.
Step-by-step explanation:
Given: Robert mixed [tex]1\dfrac13[/tex] liters of blue paint with [tex]1\dfrac23[/tex] liters of red paint to make 3 liters of purple paint.
[tex]1\dfrac13=\dfrac{4}{3}\\\\ 1\dfrac23=\dfrac{5}{3}[/tex]
Ratio of blue paint to red paint = [tex]\dfrac{\dfrac{4}{3}}{\dfrac53}=\dfrac{4}{5}=4:5[/tex]
let x be the quantity of blue paint used with 2 liters of red paint..
Then
[tex]x:2=4:5\\\\\Rightarrow\ x=\dfrac{4\times2}{5}\\\\\Rightarrow\ x=\dfrac85=1\dfrac35[/tex]
Hence, [tex]1\dfrac35[/tex] liters of blue paint have been used.
The amount of blue paint used is [tex]1\dfrac{3}{5}[/tex] liters and this can be determined by using the arithmetic operations.
Given :
Robert mixed [tex]1\dfrac{1}{3}[/tex] liters of blue paint with [tex]1\dfrac{2}{3}[/tex] liters of red paint to make 3 liters of purple paint.To make a new batch of purple paint he used 2 liters of red paint.Amount of Blue Paint = 4/3 liters
Amount of Red Paint = 5/3 liters
Now, the ratio of blue paint to red paint is given by:
[tex]=\dfrac{\dfrac{4}{3}}{\dfrac{5}{3}}[/tex]
[tex]=\dfrac{4}{5}[/tex]
Now, assume that the amount of blue paint that is used with 2 liters of red paint is 'a'. Then it is given that using the same ratio, Robert should use response area liters of blue paint, that is:
[tex]\dfrac{a}{2}=\dfrac{4}{5}[/tex]
[tex]a = \dfrac{8}{5}[/tex]
[tex]\rm a = 1\dfrac{3}{5} \; liters[/tex]
Therefore, it will be said that [tex]1\dfrac{3}{5}[/tex] liters of blue paint is used.

A gallery owner purchased a very old painting for 3000 dollars. The painting sold for 325 percent increase in price. What is the retail price of the printing?
Answers
Answer:
$12,750
Step-by-step explanation:
The price at purchase = 3000 dollars
Sale = 325 percent increase in purchase price.
325% = 3.25
3.25x3000 = 9750 dollars
So, at 325 percent increase in price, this painting sold for $9750.
The retail price of this painting =
Price at purchase + price during sale
= 3000 + 9750
= $12,750
Therefore the retail price is equal to $12,750

Answer: choice D) [tex](y-x)(y-z) \le 0[/tex]
=====================================================
Explanation:
Unfortunately, we don't have enough info to determine what x,y, and z are.
However, we do know that x < y < z is the case. Though to be more technical, x = y or y = z could be possible, but for now we'll ignore these cases.
So we'll focus on x < y < z.
This is true because 25% of the values are below x and 50% of the values are below y. So naturally x is smaller than y. Also, 75% of the values are smaller than z, so z is the largest of the three values.
Since x < y, this makes 0 < y-x when you subtract x from both sides. This is the same as saying y-x > 0. So y-x is positive.
On the other hand, because y < z, this leads to y-z < 0. So y-z is negative.
We have
y-x is some positive valuey-z is some negative valuetherefore, (y-x)(y-z) = (positive)*(negative) = negative
Overall,
(y-x)(y-z) < 0
So far, we can see that we have strict inequality. However, it is possible to have x = y or y = z be possible. Consider a set like {5,5,5,7,9}. You should find that Q1 = 5 and Q2 = median = 5 also. This example is one of infinitely many where x = y. Due to something like this, we must update (y-x)(y-z) < 0 into [tex](y-x)(y-z) \le 0[/tex]

Tyrone’s hourly wage is $18 and his net pay is 72% of his earnings. Tyrone spends about $1,800 on his monthly expenses. If Tyrone works 40 hours per week and has no other sources of income, what is his total monthly cash inflow? (Hint: Assume that there are 4 pay periods per month.)

b.
$1,080.00
c.
$1,800.00
d.
$2,073.60
Answers
His total monthly cash inflow is $2073.6 which is the correct answer would be option (D).
What are Arithmetic operations?
Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
We have been given that Tyrone’s hourly wage is $18
And he spends about $1,800 on his monthly expenses
Since Tyrone works 40 hours per week
So Monthly hours worked would be: 40 × 4 = 160
To determine the total wage
We have multiplied the hours worked by the wage rate
So total wage = hours worked × wage rate
Total Wage = 160 × 18 = 2880
Tyrone's net salary is 72% of his total income, as determined by the formula below:
Tyrone's net salary = 72% of the total Wage
Tyrone's net salary = 0.72× 2880
Tyrone's net salary = 2073.6
Therefore, His total monthly cash inflow is $2073.6 which is the correct answer would be an option (D).

Answers
Hello! :)
[tex]\large\boxed{x \approx 7.064}}[/tex]
In the diagram, we are given the opposite side of ∠A as 8.
We are trying to solve for the adjacent side, so we must use the appropriate trig.
Cotangent uses both the adjacent and opposite sides, so we can use this to find the value of x.
Cot (angle) = Adjacent / Opposite, therefore:
cot (28°) = x / 8
Multiply both sides by 8 to isolate for x:
8 · cos(28°) = x
Evalute cos(28°) using a calculator:
cos(28°) ≈ 0.88295
Multiply by 8 to solve for x:
8 · cos(28°) ≈ 7.064
