Using proportions, the solution to the given rule of three is as follows:
x = 0.61.
What is a proportion?A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using a rule of three among the proportional amounts, using basic arithmetic operations such as multiplication or division.
The multiplication can be on the line or cross multiplication, depending if the variables are inverse or direct proportional, respectively.
In the context of this problem, the rule of three that represents the relation between the variables is:
1/x = 54/33
Supposing a direct relationship, we apply cross multiplication, hence the solution for x is found as follows:
54x = 33
x = 33/54
x = 0.61.
What is the missing information?This problem is incomplete, hence we are going to suppose that we have to solve for x = alpha considering the drawing as a rule of three.

The length of the missing radius of the circle is found as 12 units.
What is defined as the tangent?A tangent is a line drawn out of an external point that passes through a point on a curve in geometry. Tangents are common in everyday life; for example, when riding a bicycle, each point on the circumference of a wheel forms a tangent with the road.For the given question;
As 16 unit line is tangent on the circle, thus it makes 90 degrees angle with the radius of the circle.
The, the triangle formed is right angled triangle.
Using Pythagorean theorem.
H² = T² + R²
Where, H is the longest side called hypotenuse = 20 units.
T is the tangent = 16 units.
R is the radius of the circle.
Putting the values and simplifying.
R² = 20² - 16²
R² = 400 - 256
R² = 144
Taking square root both side,
r = 12 units.
Thus, the length of the missing radius of the circle is found as 12 units.

What is an equation of the line that passes through the points (2,−6) and (−2,4)?
Answer:
y = - [tex]\frac{5}{2}[/tex] x - 1
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (2, - 6 ) and (x₂, y₂ ) = (- 2, 4 )
m = [tex]\frac{4-(-6)}{-2-2}[/tex] = [tex]\frac{4+6}{-4}[/tex] = [tex]\frac{10}{-4}[/tex] = - [tex]\frac{5}{2}[/tex] , then
y = - [tex]\frac{5}{2}[/tex] x + c ← is the partial equation
to find c substitute either of the 2 points into the partial equation
using (- 2, 4 ) , then
4 = 5 + c ⇒ c = 4 - 5 = - 1
y = - [tex]\frac{5}{2}[/tex] x - 1 ← equation of line

After doing some mathematical operations, the value of A is 3.465.
What are mathematical operations?An operation, also known as an "operand" or "argument," is a function in mathematics that converts zero or more input values into a clearly defined output value. The operation's arity is determined by the number of operands.Binary operations (i.e., operations of arity 2), such as addition and multiplication, and unary operations (i.e., operations of arity 1), such as additive inverse and multiplicative inverse, are the operations that are most frequently studied.So, A = π(R² - r²):
Where π = 22/7, R = 7/4 and r = 7/5.Now, solve the expression as follows:
A = π(R² - r²)A = 22/7((7/4)² - (7/5)²)A = 22/7(49/16 - 49/25)A = (22/7 × 49/16) - (22/7 × 49/25)A = (11 × 7/8) - (22 × 7/25)A = 77/8 - 154/25A = [25(77) - 8(154)]/200A = [1925 - 1232]/200A = 693/200A = 3.465Therefore, after doing some mathematical operations, the value of A is 3.465.

The larger of two numbers is three more than the smaller number. if the sum of the numbers is 51, find the numbers
Which equation accurately represents the situation. If we re-write it by replacing the “b” variable?
Answer:
(b+3)+b=51
"b" is a smaller number, that is 24.
So a larger numer is 27
Step-by-step explanation:
L = b +3
L+b = 51
(b+3) + = 51
2b + 3 = 51 >> subtract 3 to both sides
2b = 48 >> divide by 2 to both sides
b = 24
Larger = b + 3= 24 + 3= 27

The number of groups of 3 and 1/3 in 6 and 1/6 are 37/20.
We can write the given mixed fraction in the form of an improper fraction form.
Mixed fraction
Mixed fractions are those fractions that are formed by combining a whole number with a fraction.
Improper fraction
A fraction with the numerator value greater than the denominator is known as an improper fraction.
Hence, we can write,
3 and 1/3 = 10/3 and,
6 and 1/6 = 37/6
To find the number of groups of 3 and 1/3 in 6 and 1/6, we will divide 6 and 1/6 by 3 and 1/3
Hence, we can write,

We change the number of pounds of rice, r, to be the subject of the given equation by applying the principle of subject of formula. The formula would therefore be r = (10.55 - 6.20s)/1.25.
Given the phrase:
6.20s + 1.25r = 10.55
Separate 1.25r
1.25r = 10.55 - 6.20s
To identify r, divide both sides by 1.25.

(a) The cost function is C(x) =
Step-by-step explanation:
(a)
the cost function is
C(x) = 300 + 20x
(b)
the revenue function is
R(x) = 35x
(e)
the profit function
P(x) = R(x) - C(x) = 35x - 300 - 20x = 15x - 300
(d)
break-even is the point where C(x) and R(x) are equal :
C(x) = R(x)
300 + 20x = 35x
300 = 15x
x = 300/15 = 20
so, the break-even is only achieved when 20 units are produced and sold. and with more than 20 sold units the business would then make a profit.
per our restrictions only max. 19 units can be sold, so, the business will always be in the negative numbers (unless they cheat and sell virtual units that were never produced).
therefore, the product should not be produced at all.

292,000 after several years decrease by 8%
After several years of an 8% decrease, the house's value is $268,640 currently.
What is a percentage decrease?In this situation, the percentage decrease refers to the fractional devaluation of the property value.
We can compute the percentage decrease by directly determining the amount (absolute value in dollars) of the decrease or by indirectly determining the value after the decrease, using mathematical operations.
The initial value of the house = $292,000
The percentage decrease in value = 8%
The Decrease Value = $23,360 ($292,000 x 8%)
The Current Value of the house = $268,640 ($292,000 - $23,360) or {$292,000 x (1 - 8%)}
Thus, the house decreased by $23,360 or 8% and is currently worth $268,640.
