The proportion in (B) a/1650 = 20/100 can be used to find the amount of discount Mr. Werner will receive on purchase of a $1650 computer system.
What is percentage and how can its value be calculated?
A value or ratio that may be stated as a fraction of 100 is referred to in mathematics as a percentage. A portion per hundred is what the percentage denotes. Percentage refers to one in a hundred. The word "%" stands in for it. The dimension of percentages is zero. Thus, a dimensionless number is what it is called. By dividing the value by the entire value and multiplying the resulting number by 100, we can calculate the percentage.
Mathematically, Percentage = (Value/Total Value) × 100
Given, the percentage that Mr. Werner will get = 20%
The value of the discount = a
Total value of the computer = $ 1650
Therefore, using the formula established in the literature above, we have,
20 = (a/1650) × 100 ⇒ a/1650 = 20/100
Thus, the proportion in (B) a/1650 = 20/100 can be used to find the amount of discount Mr. Werner will receive on purchase of a $1650 computer system.

Find an equation for the perpendicular bisector of the line segment whose endpoints
are (-1,7) and (9, -3).
x + y - 6 is equation of slope-intercept form for the perpendicular bisector of the line segment .
What is slope-intercept form explain?
A line's equation can be written in the slope-intercept form such that the slope (steepness) and y-intercept (where the line crosses the vertical y-axis) are instantly visible. This form is frequently known as the y = mx + b form.We use formula
[tex]\frac{y - y_{1} }{y_{2} - y_{1} } = \frac{x - x_{1} }{x_{2} - x_{1} }[/tex]
[tex]\frac{y - 7 }{- 3 - 7} = \frac{x - (-1)}{9 - (-1)}[/tex]
y - 7/-10 = x+ 1/10
10(y-7) = -10( x + 1 )
10y - 70 = -10x - 10
10x + 10y - 70 + 10 = 0
10x + 10y - 60 = 0

What does the ratio of 5 to 9 compare?
92 fewer than the product of 173 and r is equal to the quotient of 247 and r
The solution of the equation is as follows:
[tex]r = \frac{46+3\sqrt{4983} }{173}[/tex] and [tex]r = \frac{46-3\sqrt{4983} }{173}[/tex]
How to represent equation?The expression can be represented in equation as follows:
173 × r - 92 = 247 / r
Note: Quotient, in mathematics, can be defined as the result of the division of a number by any divisor.
Therefore,
173 × r - 92 = 247 / r
173r - 92 = 247 / r
let's solve for the variable r in the equation
add 92 to both sides of the equation
173r - 92 = 247 / r
173r - 92 + 92 = 247 / r + 92
173r = 247 / r + 92
Therefore,
173r - 247 / r = 92
173r² - 247 / r = 92
cross multiply
173r² - 247 = 92r
173r² - 92r - 247 = 0
Therefore,
[tex]r = \frac{46+3\sqrt{4983} }{173}[/tex] and [tex]r = \frac{46-3\sqrt{4983} }{173}[/tex]

And the question below
Answer:
(a) 2nd Choice: The amount of time he has walked (in hours) when he is x kilometers from Glen City
(b) [tex]D^{-1}(x) = \dfrac{11.6 - x }{4}[/tex]
(c) [tex]D^{-1}(6.4) = 1.3 \;\text{hours}[/tex]
Step-by-step explanation:
(a)
Since D is distance in km from Glen City after t hours of walking, the inverse D⁻¹ would be the time taken in hours to walk x kilometers from the city. So the second choice
(b)
[tex]D^{-1}(x) = \dfrac{11.6 - x }{4}[/tex]
To find the inverse of a function y = f(x), interchange y and x and solve
y = 11.6 - 4x (using x instead of t)
Interchange y and x ==> x = 11.6 - 4y
Add 4y to both sides ==> 4y + x = 11.6 - 4y + 4y = 11.6
Subtract x from both sides ==> 4y = 11.6 - x
Divide both sides by 4 ==> y = (11.6 - x)/4
(c) [tex]D^{-1}(6.4) = \dfrac{11.6 - 6.4 }{4} = \dfrac{5.2}{4} = 1.3 \;\text{hours}[/tex]
Find the non-extraneous solutions of the square root of the quantity x plus 7 minus 4 equals quantity x plus 3
The non-extraneous solutions of the square root of the quantity x plus 7 minus 4 equal quantity x plus 3 is: x = -7 and x =-6.
How do we find the non-extraneous solutions?
The non-extraneous solution can be found with this calculation:
[tex]\sqrt{x} + 7 - 4 = x + 3\\\\\sqrt{x} + 7 = x + 7\\\\[/tex]
Now, we will square both sides:
[tex](x + 7) = (x + 7)^{2} \\\\(x + 7) = (x+7) (x+7)\\\\x + 7 = x^{2} + 14x + 49\\\\x = x^{2} + 13x + 42\\\\0 = (x + 7) (x+6)\\[/tex]
Thus, we have; x = -7 and x = -6
Note that we collected like terms from the figures on the left-hand-side to the figures on the right-hand side. When the lowest common multiple betwen 14 and 42 was checked, figures 7 and 6 were gotten.
When we plug figure x into both equations, we get the same figures and this confirms the solution.

You make a game where people try to throw a ball in a hole. The backboard is 34 by 30 inches. If the diameter of the hole
is 16 inches, what is the probability of getting the ball in the hole? Assume the ball either goes in the hole or hits the
board. Give your answer as a DECIMAL.
Assuming the ball either goes in the hole or hits the board, the probability of getting the ball in the hole is 0.197.
What is the probability?Probability is the chance of an expected event happening out of many other possible events.
Probability can be 1 or zero when there is 100% certainty or uncertainty. Otherwise, probability is always between 0 and 1 as a fractional value.
Dimensions of the backboard:Length = 34 inches
Width = 30 inches
Area = 1,020 in² (34 x 30)
Diameter of the hole = 16 inches
Radius of the hole = 8 inches (16/2)
Area of the hole = πR² or π(d/2)²
= ²²/₇ x 8 x 8
= ²²/₇ x 64
= 201 in²
The probability of getting the ball in the hole = the area of the hole divided by the area of the board.
= 0.197 (201/1,020).
Thus, if a person tries to throw a ball in the hole, the probability of achieving intended objective is 0.197.

Hey there!
To find this out, we have to put the numerator of the fraction as the number of marbles he has left, and the denominator as the number of marbles he had in total before he played
# of marbles in total - 56
# of marbles he has left - (56 - 32) 24
Fraction - 24/56

Elrond can sit his guest in 15 ways around the circle such that all conditions are fulfilled.
A cycle is a shape made up of all the points in a rectangle that are a certain distance from the center. It is the curve drawn by a moving location in a rectangle so that the radius from a given stage remains constant.
The radius of a circle is the distance between any two locations on the circle and the canter.
In most cases, the radius must be positive. A circle with r=0 is a degenerate instance. This section is about rounds in Euclidean geometry, primarily the Euclidean plane, unless otherwise noted.
Now we have to consider the conditions:
Elrond is holding a council at Rivendell. He's invited two men, two dwarves, and two elves, and plans to seat them all in a circle with seven seats, including himself. so 5+6=11
He understands that dwarves and elves do not get along, therefore he plans to arrange them so that no dwarf seats next to an elf. In the center of the circle is a chair. Hence 2=2 = 4
Number of ways = 11+4 = 15
Therefore Elrond can sit his guest in 15 ways around the circle such that all conditions are fulfilled.

(a) An angle measures 60°. What is the measure of its supplement?
measure of the complement:
(b) An angle measures 31°. What is the measure of its complement?
Answer:
(a) 120°
(b) 149°
Step-by-step explanation:
Supplementary angles add up to 180°
So to find the supplement of a given angle just subtract its measure from 180
(a) 180 - 60 = 120°
(b) 180- 31 = 149°
a) the supplementary angle of 60 degree is 120 degrees.
b) the complimentary angle of 31 degree is 59 degrees.
Supplementary angles are those angles whose sum comes out to be 180 degrees. to find a supplement of an angle we need to subtract the given angle from 180 degree.
supplement of 60 degree (here given angle is 60 degree)
= 180 - given angle = 180 - 60 = 120 degree
Complimentary angles are those angles whose sum comes out to be 90 degrees. To find a compliment of an angle we need to subtract the given angle from 90 degree.
compliment of 31 degree (here given angle is 31 degree)
= 90 - given angle = 90 - 31 = 59 degree
