The circular stone mound in Ireland called Newgrange has a diameter of 250 feet. A passage 62 feet long leads towards the center of the mound.
Find the perpendicular distance x from the end of the passage to either side of the mound. Round your answer to the nearest tenth.
Answer:
Step-by-step explanation:
it's 125 for the radius and also 125-62 = 63
so 125+63 = 188
188 * 62 = X^2
11656 = X^2
107.96 = x
108.0 = x ( to the nearest tenth )
The perpendicular distance x from the end of the passage to either side of the mound is : 107.93 feets
Diameter = 250
To obtain the perpendicular distance, x :
We use the relation : x × x = Length to either side of mound :
Mathematically ;
x × x = 62 ft × (250 - 62)
x² = 62 × 188
x² = 11656 ft²
Take the square root of both sides ;
x = √11656
x = 107.9629 ft
Hence, the perpendicular distance x from the end of the passage to either side of the mound is : 107.93 feets

Answer:
130
Step-by-step explanation:
Hello There!
An included angle is equal to half the measure of its included arc
So more specifically for this circle
∠mABC = [tex]\frac{1}{2}[/tex] arc(mAB)
So in order to find the value of x we are going to want an equation
Because angle ABC is equal to 1/2 of arc AB we are going to want to multiply angle ABC's expression by two
So 2(3x+32) = 10x+20
now we solve for x
step 1 distribute the 2
2 * 3x = 6x
2 * 32 = 64
now we have
6x + 64 = 10x + 20
step 2 subtract 20 from each side
64 - 20 = 44
20 - 20 cancels out
now we have 6x + 44 = 10x
step 3 subtract 6 x from each side
10x - 6x = 4x
6x - 6x cancels out
now we have 44 = 4x
step 4 divide each side by 4x
44/4=11
4x/4=x
we're left with x = 11
finally we want to plug in 11 to x for (10x+20)
10(11)+20
10*11=110
110+20=130
so arc ab = 130
Answer:
AB = 130
Step-by-step explanation:
So, according to a certain theorem to do with arcs and their angles, If a tangent and a chord intersect at a point on a circle, then the measure of each angle formed is one half the measure of its intercepted arc.
In this case, the ARC is AB, and the angle is CBA.
CBA = 3x+32
AB = 10x+20
And,
[tex]CBA = \frac{1}{2} AB[/tex]
Now,
[tex]3x+32=\frac{1}{2} (10x+20)[/tex]
[tex]3x+32=5x+10\\32=2x+10\\22=2x\\11=x[/tex]
Now we can substitute x into the equation that equals AB
[tex]10(11)+20 \\=110+20\\=130[/tex]
So, the answer is 130, sorry I took a while, the explanation takes a long time to do lol.

Torrence wants to remodel apartment . The first thing he is Going to do is replace the floors in the living space and kitchen .
Roscoe is locked outside his house.The only unlocked window is on the 2nd floor which is 24 feet from the ground. He will have to borrow a ladder from the neighbors house and place it 7 feet from the house. What length of ladder does he need to reach the 2nd floor safely
Answer:
25 feets
Step-by-step explanation:
The scenario above can be modeled and solved Using Pythagoras :
Height to second floor = 24 feets
Horizontal Distance between foot of ladder and wall = 7 feets
Let length of ladder = x
The lengtb of ladder here is the hypotenus
Recall:
Hypotenus = sqrt(opposite² + adjacent²)
Hence,
x = sqrt(24² + 7²)
x = sqrt(576 + 49)
x = sqrt(625)
x = 25
Hence, length of ladder = 25 feets

A .Write an equation for the trend line in slope -intercept form .
Given:
The graph of a trend line.
To find:
The equation of the trend line is slope intercept form.
Solution:
From the given graph it is clear that the equation of the trend line is passes through the points (0,25) and (5,50).
Slope of the line is:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{50-25}{5-0}[/tex]
[tex]m=\dfrac{25}{5}[/tex]
[tex]m=5[/tex]
The line passes through the point (0,25). So, the y-intercept of the line is 25.
Slope intercept form of a line is:
[tex]y=mx+b[/tex]
Where, m is slope and b is y-intercept.
The slope intercept from of the line is:
[tex]y=(5)x+(25)[/tex]
[tex]y=5x+25[/tex]
Therefore, the equation for the trend line in slope -intercept form is [tex]y=5x+25[/tex].

Equipment with a cost of $634800 has an estimated salvage value of $30000 and an estimated life of 4 years or 14400 hours. It is to be depreciated by the straight-line method. What is the amount of depreciation for the first full year, during which the equipment was used for 3600 hours?
Answer:
$151,200
Step-by-step explanation:
According to the problem, calculation of the given data are as follows,
Cost of Equipment = $634,800
Salvage Value = $30,000
Estimated Life = 4 years
So, we can calculate depreciation for first year by using following formula,
Amount of depreciation = Depreciable base amount ÷ Estimated Life
Where, Depreciable base amount = Cost of Equipment - Salvage Value
= $634,800 - $30,000 = $604,800
By putting the value, we get
Amount of depreciation = $604,800 ÷ 4
= $151,200

area of circle is πr²
area of semicircle is πr²/2
diameter=18
radius= 18/2=9

whats the difference between coterminal, reference, and rotational angles?
Answer:
If two angles in standard position have the same terminal side, they are called coterminal angles.
The reference angle is the acute angle (the smallest angle) formed by the terminal side of the given angle and the x-axis.
Angle of Rotation is the measurement of the amount of the angle, by which a figure is rotated counterclockwise about a fixed point, often the center of a circle. Usually clockwise rotation is called as Negative rotation
If two angles in standard position have the same terminal side, they are called coterminal angles.
What is an angle?An angle is formed when two straight lines or rays meet at a common endpoint. The common point of contact is called the vertex of an angle.
Coterminal angles are those angles that share the terminal side of an angle occupying the standard position. The standard position means that one side of the angle is fixed along the positive x-axis, and the vertex is located at the origin.
The reference angle is the acute angle (the smallest angle) formed by the terminal side of the given angle and the x-axis.
Angle of Rotation is the measurement of the amount of the angle, by which a figure is rotated counterclockwise about a fixed point, often the center of a circle. Usually clockwise rotation is called as Negative rotation.
Hence, if two angles in standard position have the same terminal side, they are called coterminal angles.

Jason and Pam recently bought a house. They financed the house with a $250,000, 30-year mortgage with a nominal interest rate of 77% compounded monthly. Mortgage payments are made at the end of each month. What would be their house payment?
Answer:
Annual payument (PMT)= $1,663.19
Step-by-step explanation:
Giving the following information:
Loan (PV)= $250,000
Monthly interest rate (i)= 0.07/12= 0.005833
Number of periods (n)= 12*30= 360 months
To calculate the monthly payment, we need to use the following formula:
Annual payument (PMT)= (PV*i) / [1 - (1+i)^(-n)]
Annual payument (PMT)= (250,000*0.005833) / [1 - (1.005833^-360)]
Annual payument (PMT)= $1,663.19

Answer:
1.) 2.5cm
2.) 1 3/4
3.) 1.6
4.) 4/5
5.) 18.84
Step-by-step explanation:
So the radius is half of the diameter, so the first one would be:
5 ÷ 2 = 2.5
We do the same thing for the next one:
3 1/2 ÷ 2 = 1 3/4
Now we have to go backwards because we have the radius and we're trying to find the diameter:
0.8 x 2 = 1.6
And the next one:
3/5 x 2 = 4/5
Now to find the circumference, we multiply the diameter by pi (3.14)
6 x 3.14 = 18.84
let me know if any of these are wrong
