Answer:
(22h - 8) centimeters
Step-by-step explanation:
Perimeter of a rectangle = 2(length + width)
= 2{(9h - 1) + (2h - 4)}
= 2(9h - 1 + 2h - 4)
= 2(11h - 4)
= (22h - 8) centimeters

The graph shows the relationship between the distance in miles and the time in minutes Scott ran during a race .
Answer:
Step-by-step explanation:
Scott ran 1 mile in 8 minutes
The slope of the line is 8 which means Scott ran 8 miles in 1-minute option (B) is correct.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The graph of a line is shown in the picture
As we can see in the graph the line passes from the origin.
Two points are (40,5) and (0,0) on the line.
Using slope formula:
m = (y2-y2)/(x2-x1)
Slope of line = (40 miles)/(5 minutes) = 8 Mikes per minute
Thus, the slope of the line is 8 which means Scott ran 8 miles in 1-minute option (B) is correct.

You have recently begun reasearching phone billing plans. Phone company A charges a flat rate of $75 a month. A flat rate means that your bill will be $75 each month with no additional costs. The billing plan for Phone Company B is a linear function of the number of texts that you send that month. That is, the total cost of the bill changes each month depending on how many texts you send.
Complete question :
You have recently begun reasearching phone billing plans. Phone company A charges a flat rate of $75 a month. A flat rate means that your bill will be $75 each month with no additional costs. The billing plan for Phone Company B is a linear function of the number of texts that you send that month. That is, the total cost of the bill changes each month depending on how many texts you send.
Input (no of text) __ cost of bill
50 ______________ $50
150 ______________$60
200 _____________ $65
500 _____________ $95
At what number of text will be phone plan be the same ; At what Number of text is company A the better choice ; At what number of text is company B the better choice.
Answer:
Cost is the same at, x = 300
at number of text, x < 300 phone plan B is better ;
at number of text, x > 300 phone plan A is better
Step-by-step explanation:
Let cost = y
Let x = Number of text
Company A :
y = 75
company B :
y = mx + c
m = slope = (y2 - y1) / (x2 - x1) = (95 - 50) / (500 - 50) = 45 / 450 = 1/10
When y = 50, x = 50
50 = 1/10(50) + c
50 = 5 + c
c = 50 - 5 = 45
Company B:
y = 1/10x + 45
When charge will be the same :
75 = 1/10x + 45
75 - 45 = 1/10x
30 = 1/10x
300 = x
Cost of phoe plan is the same at number of text = 300
At text = 299
Company B :
y = 1/10(299) + 45
y = 74.9
Hence, at number of text, x < 300 phone plan B is better
At text = 301
Company B :
y = 1/10(301) + 45
y = 75.1
Hence, at number of text, x > 300 phone plan A is better

The required 100th term in the sequence is given as 1100.
What is the 100th term in the sequences 11, 22, 33, 44, 55 … is to determine.
Arithmetic progression is the series of numbers that have common differences between preceding values.
Given sequence
11, 22, 33, 44, 55 …
Where first term ( a ) = 11 ;
common difference ( d ) = 11 - 22
= 11
The formula for the nth term of an Arithmetic progression is
a(nth) = a + ( n - 1 ) d
a (100th) = 11 + (100 - 1 )11
a (100th) = 11+ (99)11
= 11 + 1089
= 1100
The 100th term in an arithmetic sequence is 1100.
Thus, The required 100th term in the sequence is given as 1100.

The length of a rectangle is twice its breadth. The area of the rectangle is 450cm2 what is the length and breadth? (Please explain in a simple way)
Answer: 30, 15 cm
Step-by-step explanation:
Given
The length of the rectangle is twice its breadth
The area of the rectangle is [tex]450\ cm^2[/tex]
Suppose the breadth is x
So, the length is 2x
The area can be written as
[tex]\Rightarrow 2x\times x=450\\\\\Rightarrow x^2=225\\\\\Rightarrow x=15\ cm[/tex]
breadth is 15 cm, length is 30 cm

Answer:
a.the length of midsegment of an equilateral triangle with side lengths of 12.5 cm.=12.5/2=6.25cm
b.
sinceUT is the perpendicular bisector of line segment AB, where T is on AB, find the length of AT given AT = 3x + 6 and TB = 42 - x.
than AT=BT
3x+6=42-x
3x+x=42-6
x=36/4=9
AT=3×9+6=27+6=33
c.
since angle EFG has angle bisector FH, where EF = GF, find the value of y if EH = 5y + 10 and HG = 28 - y.
EH=GH
5y+10=28-y
6y=28-10

What is an equilateral triangle?
"It is a triangle whose all sides are equal in length and all angles measure 60° "
What is perpendicular bisector?"It is a line that intersects another line perpendicularly and divides it into wo equal parts."
What is angle bisector?"It is a line that splits an angle into two equal angle."
What is an isosceles triangle?"It is a triangle that has two sides of equal length."
What is midsegment of the triangle?"It is the line segment connecting the midpoints of the two sides of a triangle."
What is midsegment formula?"midsegment = 0.5 × base of triangle"
a.
We have been given an equilateral triangle with side lengths of 12.5 cm.
We need to find the length of the midsegment of an equilateral triangle.
Using midsegment formula,
⇒ midsegment = 0.5 × 12.5
⇒ midsegment = 6.25 cm
Therefore, the length of the midsegment of an equilateral triangle is 6.25 cm
b.
UT is the perpendicular bisector of line segment AB, where T is on AB
We know that the perpendicular bisector divides the line segment into two equal parts.
⇒ AT = TB
⇒ 3x + 6 = 42 - x
⇒ 3x + x = 42 - 6
⇒ 4x = 36
⇒ x = 9
So, the length of AT would be,
⇒ AT = 3x + 6
⇒ AT = 3(9) + 6
⇒ AT = 33 units
Therefore, the length of AT is 33 units.
c.
An angle EFG has angle bisector FH, where EF = GF
From given data, we can say that for it must an isosceles triangle EFG with EF = GF and base is EG.
An angle EFG has angle bisector FH and point H is on the side EG.
We know that the angle bisector of isosceles triangle is also the perpendicular bisector of the base of an isosceles triangle.
⇒ EH = HG
⇒ 5y + 10 = 28 - y
⇒ 5y + y = 28 - 10
⇒ 6y = 18
⇒ y = 3
Therefore, the value of y is 3.

Find the mean,mode,and median time
Answer:
Mean: [tex]\bar x = 40.61[/tex]
[tex]Median =40.2[/tex]
[tex]Mode = 43.4[/tex]
Step-by-step explanation:
Given
See attachment for data
Solving (a): The mean
Mean is calculated as:
[tex]\bar x = \frac{\sum x}{n}[/tex]
From the attached:
[tex]n = 14[/tex]
So, the mean is:
[tex]\bar x = \frac{43.4+43.4+43.4+43.1+43.2+40.2+40.2+40.1+40.3+39.44+39.17+38.03+38.19+36.45}{14}[/tex]
[tex]\bar x = \frac{568.58}{14}[/tex]
[tex]\bar x = 40.61[/tex]
Solving (b): The median
[tex]n = 14[/tex]; this is an even number. So, the median is:
[tex]Median = \frac{1}{2}(n+1)[/tex]
[tex]Median = \frac{1}{2}(14+1)[/tex]
[tex]Median = \frac{1}{2}(15)[/tex]
[tex]Median = 7.5th[/tex]
This implies that the median is the average of the 7th and 8th item.
Next, is to order the data (in ascending order): 36.45, 38.03, 38.19, 39.17, 39.44, 40.1, 40.2, 40.2, 40.3, 43.1, 43.2, 43.4, 43.4, 43.4.
The 7th and 8th items are: 40.2 and 40.2
The median is:
[tex]Median = \frac{1}{2}(40.2 + 40.2)[/tex]
[tex]Median = \frac{1}{2}*80.4[/tex]
[tex]Median =40.2[/tex]
Solving (c): The mode
43.4 has the highest number of occurrence.
So:
[tex]Mode = 43.4[/tex]

Answer:
15.95 feets
Step-by-step explanation:
Given that:
Angle of elevation = 62°
Using trigonometric relation :
Tanθ = opposite / Adjacent
From the drawing attached :
Opposite = 30 feets
Distance between girl and lighthouse = d
Tan 62 = 30 / d
1.8807264 * d = 30
d = 30 / 1.8807264
d = 15.951283
