Answer:
20% 0f $65.00 is $13
$13 - $5= $8
Step-by-step explanation:
Percentage solution with steps:
Step 1: Our output value is 65.00.
Step 2: We represent the unknown value with $x$.
Step 3: From step 1 above,$65.00=100\%$.
Step 4: Similarly, $x=20\%$.
Step 5: This results in a pair of simple equations:
$65.00=100\%(1)$.
$x=20\%(2)$.
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
$\frac{65.00}{x}=\frac{100\%}{20\%}$
Step 7: Again, the reciprocal of both sides gives
$\frac{x}{65.00}=\frac{20}{100}$
$\Rightarrow x=13$
Therefore, $20\%$ of $65.00$ is $13$
a unicorn is tethered by a 20-foot silver rope to the base of a magician's cylindrical tower whose radius is 8 feet. the rope is attached to the tower at ground level and to the unicorn at a height of 4 feet. the unicorn has pulled the rope taut, the end of the rope is 4 feet from the nearest point on the tower, and the length of the rope that is touching the tower is $\frac{a - \sqrt{b}}{c}$ feet, where $a$, $b$, and $c$ are positive integers, and $c$ is prime. find $a b c$.
The values of a=60, b=750, c=3, a+b+c= 813 as determined by Pythagorean Theorem..
What is Pythagorean Theorem?
A geometric theorem states that the square of a right triangle's hypotenuse equals the sum of the squares of its other two sides.
Call the circle's center O, the unicorn's tether point A, and the final spot where the rope reaches tower B. Triangle OAB is a right triangle since BA is a tangent line at point B and OB is a radius. We determine the horizontal component of AB has length [tex]4\sqrt{5}[/tex] using the Pythagorean Theorem.
The cylinder is "unrolled" to become a flat surface. Let C be the rope's bottom tether, D the point below A on the ground, and E the point directly beneath B. Triangles CDA and CEB share characteristics of right triangles. The Pythagorean Theorem states that CD=8cdotsqrt6.
Let x represent the size of CB.[tex]CD=8\cdot\sqrt{6}[/tex]
[tex]\[\frac{CA}{CD}=\frac{CB}{CE}\implies \frac{20}{8\sqrt{6}}=\frac{x}{8\sqrt{6}-4\sqrt{5}}\implies x=\frac{60-\sqrt{750}}{3}\][/tex]

a=60, b=750, c=3,a+b+c= 813 as determined by Pythagorean Theorem.

Using factorisation method we will get two factors
Factoring quadratics is a method of expressing the quadratic equation ax2 + bx + c = 0 as a product of its linear factors as (x - k)(x - h), where h, k are the roots of the quadratic equation ax2 + bx + c = 0. This method is also is called the method of factorization of quadratic equations. Factorization of quadratic equations can be done using different methods such as splitting the middle term, using the quadratic formula, completing the squares, etc.

If [tex]h(x)=\frac{-5}{6} x+\frac{7}{8}[/tex] then the value of h(3) = -13/8 , h(4) = -59/24 , h(-1/2) = 31/24 .
In the question , the equation is given as
[tex]h(x)=\frac{-5}{6} x+\frac{7}{8}[/tex] ....(i)
Part(a)
To find the value of h(3)
we substitute the value of x=3 .
On substituting the value of x=3 in equation (i),
we get ,
h(3) = (-5/6)3+7/8
= -15/6+7/8
taking LCM of 6 and 8 as 24, we get
= -60/24 + 21/24
= (-60+21)/24
= -39/24
Writing in the simplest form we get
= -13/8
so, the value of h(3)= -13/8 .
Part(b)
for h(4) ,we substitute the value of x=4 .
On substituting the value of x=4 in equation (i) ,
we get ,
h(4) = (-5/6)4+7/8
= -20/6+7/8
taking LCM of 6 and 8 as 24, we get
= -80/24 + 21/24
= (-80+21)/24
= -59/24
so , the value of h(4)= -59/24 .
Part(c)
for h(-1/2) ,we substitute the value of x as -1/2 .
On substituting the value of x = -1/2 in equation (i) ,
we get ,
[tex]h(\frac{-1}{2} )=\frac{-5}{6} *\frac{-1}{2} +\frac{7}{8}[/tex]
= 5/12 +7/8
taking LCM of 12 and 8 as 24, we get
= 10/24 + 21/24
= (10+21)/24
= 31/24
so , the value of h(-1/2)= 31/24 .
Therefore , if h(x) = (-5/6)x+7/8 the the value of h(3)= -13/8 , h(4)= -59/24 and h(-1/2)= 31/24 .

Answer:
[tex]-\sqrt{2}[/tex]
Step-by-step explanation:
Note that:
[tex]a^2-2ab+b^2=(a-b)^2 = 4ab \\ \\ a^2 + 2ab+b^2 = (a+b)^2 = 8ab \\ \\ \implies \frac{a+b}{a-b}=\frac{\sqrt{8ab}}{-\sqrt{4ab}}=-\sqrt{2}[/tex]
Answer:
[tex]\sf \dfrac{a+b}{a-b}= -\sqrt{2}[/tex]
Step-by-step explanation:
[tex]\sf a^2 + b^2 = 6ab \qquad where\:\:0 < a < b[/tex]
Basic formula:
[tex]\sf (a + b)^2 = a^2 +b^2 +2ab[/tex]
[tex]\sf (a - b)^2 = a^2 + b^2 -2ab[/tex]
solve for a + b
[tex]\sf \rightarrow a^2 + b^2 = 6ab[/tex]
[tex]\sf \rightarrow (a+b)^2-2ab = 6ab[/tex]
[tex]\sf \rightarrow (a+b)^2 = 6ab+2ab[/tex]
[tex]\sf \rightarrow (a+b)^2 = 8ab[/tex]
[tex]\sf \rightarrow a+b = \pm \sqrt{8ab}[/tex]
solve for a - b
[tex]\sf \rightarrow a^2 + b^2 = 6ab[/tex]
[tex]\sf \rightarrow (a-b)^2 + 2ab = 6ab[/tex]
[tex]\sf \rightarrow (a-b)^2 = 6ab-2ab[/tex]
[tex]\sf \rightarrow (a-b)^2 = 4ab[/tex]
[tex]\sf \rightarrow a-b = \pm \sqrt{4ab}[/tex]
Now solve for (a + b)/(a - b)
[tex]\sf \rightarrow \dfrac{a+b}{a-b}= \dfrac{\pm\sqrt{8ab} }{\pm\sqrt{4ab} }[/tex]
[tex]\sf \rightarrow \dfrac{a+b}{a-b}= \pm \sqrt\dfrac{8ab }{4ab}[/tex]
[tex]\sf \rightarrow \dfrac{a+b}{a-b}= \pm \sqrt{2}[/tex]
As, the value of b is greater than the value of a and both the values a and b are greater than 0. It turns the value of expression negative as the denominator will be always evaluated to negative integer and the numerator value always > 0. So, the answer will be negative, -√2.
[tex]\sf \rightarrow \dfrac{a+b}{a-b}= - \sqrt{2}[/tex]

The statement that is true is completing the solution for the equation is the same as completing the solution for the inequality. The student would divide both sides by -2 in either case. Option A
How to determine the statementFrom the information given, we have that;
The linear equation is ;
-2x + 3 = 6
Let's solve for x
First, collect like terms
-2x = 6 - 3
-2x = 3
Divide both sides by - 2
x = 3/ -2
The linear inequality is;
-2x + 3 < 6
collect like terms
-2x < 6 - 3
Make 'x' the subject by dividing both sides by -2
-2x/ -2 = 3/ -2
x = 3/ -2
We can see that the linear equation and the linear inequality have the same solution and steps.
Thus, the statement that is true is completing the solution for the equation is the same as completing the solution for the inequality. The student would divide both sides by -2 in either case. Option A

PUNTOS Write the equation of the line parallel to y = -1/3x + 4 and passing through the point (-6, -9). Be sure to write your answer in slope-intercept form(y=mx+b)
The slope intercept of the line is y = -1/3x -11
Slope-intercept is one of the special forms of line equation
The slope intercept of a line can be found by solving the slope-intercept equation of a line which is parallel to that line.
Slope-intercept equation is
y = mx + b
where m is the slope and b is the intercept.
The slope-intercept equation of the parallel line is
y = -1/3x + 4
The slope will be the same for both lines as they were parallel to each other.
Thus m = -1/3
The point in which the line passes is given as (-6,-9)
So with these data, We can find the intercept of the line
y = mx + b
where m = -1/3 and (x,y) is (-6,-9),Thus
-9 = -1/3(-6) +b
-9 = 6/3 +b
-9 = 2 + b
b = -9-2
b = -11
Thus the intercept of the line passing through the point (-6,-9) is -11
Thus, the slope-intercept equation of the line we need to find is
y = -1/3x -11

Explain the properties used to solve inequalities and how they are different from properties of equality
The major difference between inequality and equality is that equality represents a particular value(s) while inequality represents a range of values that are in a specific direction.
What are the properties that are used to solve inequalities?This must be noted when solving questions on equality and inequality.
For example:
x = a means that the value of x is a. It represents a particular value which is a
x < a represents all the values that are less than a.
x ≤ a represents values from a and below.
x > a represents all the values that are greater than a
x ≥ a means that the values of x are greater than or equal to a.
From the examples given above, it is obvious that a change in the direction of the inequality sign changes the values of the data represented by the inequality.
