Answer:
N/a^3/2
Step-by-step explanation:
loga(N/X)=3/2
N/X= a^3/2
X= N/a^3/2
Step-by-step explanation:
When subtracting logarithms with the same base, it is equivalent to combining them into one logarithm, then dividing the arguments inside:
[tex] log_{a}(n) - log_{a}(x) = log_{a}( \frac{n}{x} ) [/tex]
Then use the formula:
[tex] log_{a}( \frac{n}{x} ) = \frac{3}{2} [/tex]
[tex]{a}^{ \frac{3}{2} } = \frac{n}{x} [/tex]
[tex]x = n {a}^{ - \frac{3}{2} } [/tex]

Given circle E with diameter \overline{CD} CD and radius \overline{EA} EA . \overline{AB} AB is tangent to E at A. If EA=18 and DB=12, solve for AB. Round your answer to the nearest tenth if necessary.
The line AB from the diagrammatic expression of the tangent of the circle shows that line AB is 24.0
What is the tangent of a circle?A tangent of a circle is a line that intersects the circle at a single point. The site at which the tangent intersects the circle is referred to as the site of tangency.
From the given information:
Line |CD| = Diameter Line |EA| = radius = 18Line |DB| = 12Then, we can infer that line EA = DE since they are both (radii of the circle.)
Line |DE| = |EA| = 18By using the formula for Pythagoras theorem, we can find line |EA|.
hyp² = opp² + adj²where;
Line |BE| = hypotenuse = DB + BE = 12 + 18 = 30Line |AB| = opposite (x) = ???Line |EA| = adjacent = 18Thus;
30² = x² + 18²
900 = x² + 324
-x² = -900 + 324
x = √576
x = 24.0

one sixth of a number is 9 algebraic expression
Answer:
x= 54
Step-by-step explanation:
let the number be (x)
so One sixth of x will be 9
numerically,
1/6 × (x) =9
x= 9×6
x= 54
One-sixth can be written as [tex]^1/_6[/tex]
now, let the number be y
so one-sixth of y is written as
[tex]^1/_6~y~=~9[/tex]
If it's necessary to solve for y, consult the [Solving for y] section of this ans ↓[Solving for y]First we need to get rid of the fraction, one-sixth.
since in mathematics we can't just terminate fractions without altering the equation/expression itself, we need to perform an operation.
the first one is multiplication; we will multiply both sides of the equation by 6 (the denominator of the fraction)
[tex]^1/_6*6~y~=~9~*~6}[/tex]
On the left-hand side the 6's cancel, and we're left with
1 y = 9 * 6
Or
y = 9* 6
Which simplifies to :
y = 54

Timothy has a model of an armoured vehicle created using a scale of 1 : 72. If the length of the model is 3.3 inches, what is the actual length of the ed. e Limit vehicle, in feet?
Answer:
Length of armoured vehicle: 19.8 ft
Step-by-step explanation:
1 is to 3.3 in as 72 is to x:

From the linear function formed by the points given in the table, it is found that the x-intercept is of -14.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0.In this problem, when x increases by 20, y decays by 6, hence the slope is given by:
[tex]m = -\frac{6}{20} = -0.3[/tex]
Then:
y = -0.3x + b.
When x = -54, y = 12, hence:
y = -0.3x + b
12 = -0.3(-54) + b.
b = -4.2.
Thus, the equation is:
y = -0.3x - 4.2.
The x-intercept is the value of x when y = 0, hence:
-0.3x - 4.2 = 0.
x = -4.2/0.3
x = -14

of the ten menu items at deli, 7 are sandwiches With meat, 2 are sandwiches without meat, and 1 is a desert.Write the fraction of menu options that are sandwiches as a fraction with a denominator of 100. Then write the fraction as a decimal.
The fraction of menu options that are sandwiches is 70/100, or 0.7 in decimal form.
How to write the fraction?
Out of the 10 options on the menu, 7 are sandwiches.
Then the fraction of options in the menu that are sandwiches is:
7/10
But we want the denominator to be 100, so we multiply both numerator and denominator by 10 to get:
7*10/10*10 = 70/100
This is the fraction we wanted.
Now, we want it as a decimal, this will be:

Find the area of the shaded region
Answer:
Step-by-step explanation:
Remark
The easiest way is to find the area of the trianlge and subtract the area of the circle.
Area of the triangle
Area of the triangle = 1/2 b * h
b = 40 km
h = 27 km
The height is a little tricky. Since the angle at the base is greater than 90, you have to extend the base. Drop a line from the peak to the base making a right angle with the base. This has been done for you: the height is 27 km
Area of the triangle = 1/2 * 40 * 27
Area of the triangle = 540
Area of the circle
Area of the circle = pi r^2
r = d/2
r = 12/2
r = 6
Area of the circle = pi * 6*6
Area of the circle = 3.14 * 36
area of the circle = 113.04
Area of the shaded region
Area of the shaded region = area of triangle - area of the circle
Area of the triangle = 540
Area of the circle = 113.04
Area of the shaded region = 540 - 113.04
Area of the shaded region = 426.96

A Parallelogram has one angle that measures 10°. What are the measures of the other three angles in the parallelogram?
one angle= 10°
to find:the remaining 3 angles.
solution:angle sum= 360°
2x10=20
360–20=340
340/2=170
so, the remaining 3 angles are 10, 170 and 170.
Answer:
10, 170, 170
Step-by-step explanation:
Opposite angles of parallelogram are equal
Consecutive angles in a parallelogram are supplementary (add 180°)
Interior angles in a quadrilateral add up to 360°.
10+10=20 (2 opposite angles of 10 each)
360-20= 340
340/2 = 170 (2 opposite angles of 170)
10+170 = 180 (2 consecitive angles supplementary)
10+10+170+170=360

A. Find the amount of interest. Show the math computation use to find the amount of interest.
B. What was the monthly payment? Show the work used to find this answer.
Answer:
A. Interest = $1710
B. Monthly payment = $467.08
Step-by-step explanation:
Simple interest formula:
[tex]\sf A = P(1+rt)[/tex]
where:
A = final amountP = principalr = annual interest rate (in decimal form)t = time (in years)Given:
P = $9,500r = 9% = 0.09t = 2 yearsSubstitute given information into the formula:
[tex]\begin{aligned} \sf \implies A & = \sf 9500(1+0.09 \cdot 2)\\& = \sf 11210 \end{aligned}[/tex]
Interest = final amount - principal
= 11210 - 9500
= $1710
term = 2 years
1 year = 12 months
⇒ term = 2 × 12 = 24 months
Monthly payment = final amount ÷ months in term
= 11210 ÷ 24
= $467.08
So
[tex]\\ \rm\rightarrowtail I=\dfrac{PRT}{100}[/tex]
[tex]\\ \rm\rightarrowtail I=\dfrac{9500(2)(9)}{100}[/tex]

Step-by-step explanation:
Given equation
[tex] \sf {x}^{2} - 9x + 20 [/tex]
Rules for factorisation,
distribute the middle term in such a way that constant of each term when multiplied outputs the last number.
The middle term -9x can be written as sum of -5x and -4x, and when we multiply -5 with -4 it turns+20.
rewriting equation,
[tex] \sf \hookrightarrow {x}^{2} - 5x - 4x + 20 \\ \sf \hookrightarrow x(x - 5) - 4(x - 5) \\ \sf \hookrightarrow \: (x- 4)(x - 5)[/tex]

Answer:
(x - 5)(x - 4)[tex] \: [/tex]
Step-by-step explanation:
So, here we have to factorise the polynomial :
[tex]\\ \longrightarrow \sf \qquad {x}^{2} - 9x + 20\\ \\[/tex]
We are to find two numbers such that,
[tex]\\ {\longrightarrow \pmb{\sf {\qquad p + q = 9 \:}}} \\ \\[/tex]
[tex]\\ {\longrightarrow \pmb{\sf {\qquad p \times q = 20 \:}}} \\ \\[/tex]
The two numbers are 4 and 5, so
[tex]\\ \longrightarrow \sf \qquad {x}^{2} - 5x - 4x+ 20\\ \\[/tex]
Finding common factors :
[tex] \\ {\longrightarrow \pmb{\sf {\qquad {x} (x - 5) - 4(x - 5) \:}}} \\ \\[/tex]
[tex]{\longrightarrow \pmb{\sf {\qquad (x - 5) (x - 4) \:}}} \\ \\[/tex]

Hannah is solving a quadratic equation in the form ax^2+ bx + c = 0
She has got to this point in her working out.

Find the values of a, b and c for the equation Hannah is solving.
A quadratic equation is represented by the form ax^2+ bx + c = 0
The values of a, b and c are 1, -3 and -5, respectively
How to determine the values of a, b and c?The solution is given as:
[tex]x = \frac{3 \pm \sqrt{29}}2[/tex]
The solution to a quadratic equation is represented as:
[tex]x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]
By comparing [tex]x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex] and [tex]x = \frac{3 \pm \sqrt{29}}2[/tex], we have:
-b = 3
So, b = -3
Also, we have:
2a = 2
So, a = 1
Also, we have:
b² - 4ac = 29
Substitute values for a and b
(-3)² - 4 * 1 * c = 29
This gives
9 - 4c = 29
Subtract 9 from both sides
-4c = 20
Divide by -4
c = -5
Hence, the values of a, b and c are 1, -3 and -5, respectively
