Answer:
The equation the repair service use to charge customers is c = 30h + 40
Step-by-step explanation:
If h = 1
Cost, c = 30h + 40
= 30(1) + 40
= $70
h = 2
c = 30(2) + 40
= $100
h = 3
c = 30(3)+ 40
= $130
h = 4
c = 30(4) + 40
= $160
h = 5
c = 30(5) + 40
= $190
h = 6
c = 30(6) + 40
= $220
$22,000
$22,500
$24,000
$31,500

[tex]\begin{aligned}\implies \textsf{Area} & =\left(\dfrac{120^{\circ}}{360^{\circ}}\right) \cdot 3.14 \cdot 9^2\\\\& = \dfrac{1}{3} \cdot 3.14 \cdot 81\\\\& = 84.78\\\\ & = 84.8\: \sf (nearest\:tenth)\end{aligned}[/tex]
Answer:

Step-by-step explanation:
the area (A) of the sector is calculated as
A = area of circle × fraction of circle
= πr² × [tex]\frac{120}{360}[/tex]
= π × 9² × [tex]\frac{1}{3}[/tex]
= 81π × [tex]\frac{1}{3}[/tex]
= 27π

The length of a rectangle is 5times
the breadth, if the perimeter of a
rectangle is 72cm find the area.
Answer:
Step-by-step explanation:
Formula Development
Let the width = w
Let the Length = 5*w
P = 72
P =2w + 2L
Area = 5w * w
Solution
Start with the Perimeter. Solve for w.
P = 2w + 2L Substitute the givens
72 = 2w + 2*5w Combine
72 = 2w + 10w Combine Combine again
72 = 12 w Divide by 12
72/12 = 12w/12
w = 6
Now for the area
Area = 5w * w
w = 6
Area = 5*6*6
Answer: Area = 180 cm^2

What are all values of x for which the series n 3^n/x^n converges
The interval of the convergence is x < -3 or x > 3 if the series n 3^n/x^n goes infinitely.
What is convergent of a series?A series is convergent if the series of its partial sums approaches a limit; that really is, when the values are added one after the other in the order defined by the numbers, the partial sums getting closer and closer to a certain number.
We can find the interval for the convergent by root test.
Like the Ratio Test, the root Test is used to determine absolute convergence (or not) with factorials, the ratio test is useful.
For the given series:
[tex]\sum^{\infty}_{n=0}\dfrac{3^n}{x^n}[/tex]
As the series goes infinitely, we can use root test.
By the root test, the convergence interval will be;
The interval of convergence is:
x < -3 or x > 3 we can write this as:
|x| < 3
Thus, the interval of the convergence is x < -3 or x > 3 if the series n 3^n/x^n goes infinitely.

Marisa, who raise the price of her earrings so that she will make a profit of $5.00 on each pair, expect to make a profit with her company.
What is the unit price?The unit price is the amount of money required to buy one unit of a item or goods.
To find the unit price, divide the total cost of the goods to the total number of goods.
The cost of repair will now be $60. Thus, the total cost of 50 earrings is,

ABCD is a rhombus.

The coordinates of A are (5, 11)
The equation of the diagonal DB is y = x + 5
The equation of the diagonal AC can be written
in the form y = mx + c where m and c are integers.
Work out the value of m and the value of c.
From the information given, it is correct to state that M = - 3; while c = 26. This problem relates to a Rhombus. See the definition of a Rhombus below.
What is a Rhombus?A Rhombus is a 2-dimensional quadrilateral whose sides have equal length.
What are the steps for finding M and C?It is given that ABCD is a Rhombus. This means that
AC ⊥ BD; andLine DB is y = (1/3)x + 5Hence, the slope of AC = -3.
This is arrived at as follows:
Given that the diagonals of Rhombus' are perpendicular, hence
I/3 x m = -1 ⇒ -3
⇒ Line y-11 = -3 (x-5)
⇒ Line AC thus ⇒ y = -3x + 26
Recall that the coordinates are (5, 11). Thus let y = -3x + b
Hence, -3 x 5 + b = 11
b = 11 + 15
b = 26.
Therefore the equation is given as:
y = -3X + 26 were:

b) none of these
c) a tree diagram
d) an area model
The tree diagram would be best for a probability calculation with two or more “and” statements, option (c) is correct.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words the probability is the number that shows the happening of the event.
A probability calculation can be computed using multiple models, each of which is dependent on the given parameters. A graphical model, such as a tree diagram, or an analytical model, such as the systematic list model, can be used.
Tree diagram models are useful for visually showing complex probabilities and aiding solution visualization.

An angle measures 54° more than the measure of its supplementary angle. What is the measure of each angle?
Answer:
Step-by-step explanation:
we know that If two angles are complementary, then their sum is equal to 90 degrees
Letx -----> the measure of an angle
y-----> the measure of he other angle
we know thatx+y=90 -----> y=90
-x -----> equation
Ax=y+54 ----> equation
Bsubstitute equation B in equation A and solve for yy=90-(y+54)
y=90-y-542y=36y=18°
Find the value of xx=y+54 -----> x=18+54=72°
thereforeThe measure of the angles are 72 degrees and 18 degrees

An angle measures 54º more than the measure of its supplementary angle. What is the measure of each angle?
[tex]\blue{\textsf{\textbf{\underline{\underline{Answer:-}}}}[/tex]
Angle Measurements:- 63º and 117º
[tex]\blue{\textsf{\textbf{\underline{\underline{How\:to\:Solve:-}}}}[/tex]
Supplementary angles add up to 180º.
Now, let the unknown angle be n.
Set up an equation:-
[tex]\bigstar[/tex] [tex]\textsf{n+n+54=180}[/tex] (remember, supplementary angles add up to 180)
Add the n's :
[tex]\textsf{2n+54=180}[/tex]
Subtract 54 on both sides:
[tex]\textsf{2n=126}[/tex]
Divide by 2 on both sides:
[tex]\textsf{n=63\textdegree}[/tex]
Now, add 54 to find the other angle:
63+54=117
Check:-
We can easily check our work by adding the two angles together and seeing whether or not we end up with 180º.
[tex]\textsf{63+117=180}[/tex]
