JK = 3.51
WK = 9.15
∠J = 69°
Step-by-step explanation:
sin 21° = JK/9.8
0.3584 = JK/9.8
cos 21° = WK/9.8
0.9336 = WK/9.8
WK = 9.15
∠J = 90° - 21° = 69°

(a) What is 0.36 as 36 repeating expressed as a fraction in simplest form?
(b) What is 0.36 as 6 repeating expressed as a fraction in simplest form?
(c) What is 0.36 expressed as a fraction in simplest form?
Answer:
Step-by-step explanation:
A.the fraction is technically 36/99, but simplified version is 4/11
X = 0.36363636......
100x = 36.363636.....
100x - x =36.363636 - 0.363636....
99x=36
X=36/99
= 4/11
0.36363636363 is the first repeating fraction and 36.36363636 is the second repeating fraction, because you multiply it by 100.
b.0.3666 ... = 11/ 30
Explanation:
x = 0.3666 . .
(1) 10 x = 3.666 ...
(2) 100 x = 36.666 ...
(2)-(1):
100 x − 10 x = 36.666 ... − 3.666 ...
90 x = 33
x = 33/ 90 = 11/ 30
c.9/25
0.36 in the simplest form as fraction is 9/25.

what is the equation of the line that passes through the points (4,3) and (6, 2)?
Answer:
y = -1/2 x + 5
Step-by-step explanation:
1) y = mx + b
2) m is the slope and b is the y-intercept
3) For lines like these, the slope is always defined as "the change in y over the change in x" or, in equation form: m = y2 - y1 / x2 - x1
4) Also, let's call the second point you gave, (6,2), point #2, so the x and y numbers here will be called x2 and y2. Or, x2=6 and y2=2.
5) Now, just plug the numbers into the formula for m above, like this: m = -1/2
6) So, we have the first piece to finding the equation of this line, and we can fill it into y=mx+b like this: y = -1/2 x + b
7) To find b, think about what your (x,y) points mean:
(4,3). When x of the line is 4, y of the line must be 3.
(6,2). When x of the line is 6, y of the line must be 2.
8) You can use either (x,y) point you want..the answer will be the same:
(4,3). y=mx+b or 3=-1/2 × 4+b, or solving for b: b=3-(-1/2)(4). b=5.
(6,2). y=mx+b or 2=-1/2 × 6+b, or solving for b: b=2-(-1/2)(6). b=5.
9) So, this means that the equation of the line is y = -1/2 x + 5
Geometry The length of a rectangle is represented by 2x + 3, and its
width is represented by 3x + 7. The perimeter of the rectangle is 35 units.
Find the value of x
Answer:
x = 1.5
Step-by-step explanation:
The perimeter of a rectangle is calculated by adding widht and height and multiply it by 2
The lenght is 2x + 3 and the width is 3x + 7
(2x + 3 + 3x + 7) *2 = 10x + 20 this is the perimeter which is given as 35 units
10x + 20 = 35 subtract 20 from both sides
10x = 15 divide both sides by 10
x = 1.5

List the first three wholenumbers greater than 50 that will have a remainder of 7 when you divide by 9/ ?
Answer:
52, 61 and 70
Step-by-step explanation:
Given
[tex]Divisor = 9[/tex]
[tex]Remainder = 7[/tex]
Required
Determine first 3 possible dividends
The relationship between the [tex]dividend,\ divisor,\ quotient\ and\ remainder[/tex] is:
[tex]Dividend = Divisor * Quotient + Remainder[/tex]
Substitute: [tex]Divisor = 9[/tex] and [tex]Remainder = 7[/tex]
[tex]Dividend = 9* Quotient + 7[/tex]
Since the Dividends must be greater than 50, then the values of the quotient will be 5, 6 and 7
So, we have:
[tex]Dividend = 9* 5 + 7 = 45 + 7 = 52[/tex]
[tex]Dividend = 9* 6 + 7 = 54 + 7 = 61[/tex]
[tex]Dividend = 9* 7 + 7 = 63 + 7 = 70[/tex]
Hence, the three numbers are: 52, 61 and 70

Answer:
x = 95°
y = 147°
z = 128°
Step-by-step explanation:
z = 180 - 52 = 128°
x: first find the remaining angle in the big triangle, 180 - (45 + 50) = 85°
x = 180 - 85 = 95°
y: first find the remaining angle in the small triangle, 180 - (95 + 52) = 33°
y = 180 - 33 = 147°

The leaning tower of Pisa in Italy has a height of 183 feet and is 4∘ off vertical.
We have to determine the horizontal distance d that the top of the tower is off vertical. round your answer to the nearest tenth of a foot.
What is the horizontal distance d?
The horizontal displacement of a projectile depends upon the initial horizontal speed and the time of travel. The vertical displacement of a projectile.
The horizontal distance d that the top of the tower is off vertical.
183 times 1.04=190.32.
Therefore the horizontal distance d that the top of the tower is off vertical is equal to the 190.32feet.

A) write an expression for the perimeter of the rectangle
B) given that the perimeter is 30cm, make and solve and equation for d.
C) find the area of this rectangle
9514 1404 393
Answer:
A) P = 8d +14
B) d = 2
C) 56 cm^2
Step-by-step explanation:
A) The perimeter is the sum of all of the side lengths.
P = 2(L +W)
P = 2((3d +2) +(d +5)) = 2(4d +7)
P = 8d +14
__
B) Using 30 for P, we have ...
30 = 8d +14
16 = 8d . . . . . . . subtract 14
2 = d . . . . . . . . . divide by 8
__
C) The side lengths are ...
3d +2 = 3(2) +2 = 8 . . . . cm
d+5 = 2+5 = 7 . . . . cm
Then the area is ...
A = LW
A = (8 cm)(7 cm) = 56 cm^2

The angles surrounding the point p are 90 degrees
Then using the angle given, find the missing angles.
JPH = 90
HJP = 49
90+49 = 139
180 - 139 = 41
Therefore JHP = 41
HLP = HJP = 49
HLP = 49
KLP = 72
KLP + HLP = 72 + 49 = 121
Therefore, HLK = 121
LP = JP = 16
JP = 16

The angle of depression of a buoy from a point on a lighthouse 120 feet above the water's surface is 10 degrees. Find the distance from the lighthouse to the buoy. Leave answer with two decimal places.
Answer:
680. 55 feets
Step-by-step explanation:
From the diagram, distance from lighthouse to buoy = x
Angle from top of lighthouse to buoy = (90 - 10) = 80°
Using the trigonometric relation :
Tanθ = opposite / Adjacent
Opposite = x
Adjacent = 120
Tan 80 = x / 120
5.6712818 = x / 120
x = 5.6712818 * 120
x = 680. 55 feets
