In ΔFGH, the measure of ∠H=90° GF = 37 HG = 12 and FH = 35.
What ratio represents the sine of ∠F?
Answer:
[tex]\sin F =\dfrac{12}{37}[/tex]
Step-by-step explanation:
We are given the following in the question:
GF = 37 units
HG = 12 units
FH = 35 units
We have to find the ratio that represents sine of ∠F.
Formula:
[tex]\sin F = \dfrac{\text{Perpendicular}}{\text{Hypotenuse}}\\\\\sin F = \dfrac{HG}{GF}=\dfrac{12}{37}[/tex]
is the required ratio of sine of ∠F.
The attached image shows the triangle.
In the right triangle ΔFGH, the sine of ∠F is represented by the ratio of the opposite side (HG) to the hypotenuse (FH), so the sine of ∠F is 12/35.
Explanation:In the right triangle ΔFGH, the sine of an angle is defined as the ratio of the length of the opposite side to the length of the hypotenuse. Considering ∠F, the side opposite to it would be HG and the hypotenuse in this scenario would be FH.
Given that HG = 12 and the length of the hypotenuse FH = 35, then the sine of ∠F (sin F) would be represented by the ratio 12/35.
Therefore, the sine of ∠F in the triangle ΔFGH is 12/35.

Step-by-step explanation:
A chain lying on the ground is 19 meters long and its mass is 84 kilograms. The chain is threaded through a pulley, which is fixed to the ground, and pulled directly up so that it forms the shape of an L. How much work is required to raise one end of the chain to a height of 7 meters? Use that the acceleration due to gravity is 9.8 m/s^2. You may assume that the chain slides effortlessly and without friction along the ground as its end is lifted.
Answer:
Step-by-step explanation:
Given that, the length of the chain is
L= 19m
And the mass of the chain is
M= 84kg
Work to raise the chains to a height of
H = 7m
Acceleration due to gravity
g = 9.8m/s²
Since the chain is 19m long and it has a mass of 84kg
Then, it mass/ length is 84/19
M/L = 4.42kg/m
So, it weight / length is mass / length × gravity
W/L = M/L × g
W/L = 4.42 × 9.8
W/L = 43.33 N/m
So, workdone can be calculated using
Work = ∫F∆x
Work = ∫(W/L)•xdx.
Work = ∫43.33x dx. From x = 0 to 7
Work = 43.33 ∫x dx.
Work = 43.33 x²/2. From x = 0 to 7
Work = 21.66 [x²] from x = 0 to 7
Work = 21.66 ( 7²-0²)
Work = 21.66 × 49
Work = 1061.5 Joule
The workdone to lift the chain to 7m is 1061.5 J
"When work is done to lift the chain to 7m is 1061.5 J. To understand the calculations, check below".
Calculation of Acceleration due to GravityGiven that, the length of the chain as per the question is:
L= 19m
And also the mass of the chain is
Then M= 84kg
Now Work to raise the chains to a height of
After that H = 7m
Acceleration due to gravity
Then g = 9.8m/s²
Since When the chain is 19m long and it has a mass of 84kg
Then, it mass/ length is 84/19
M/L = [tex]4.42kg/m[/tex]
After that, it weight / length is mass / length × gravity
W/L = M/L × g
W/L = 4.42 × 9.8
W/L = 43.33 N/m
Then, work done can be calculated using
Work is = ∫F∆x
Work is = ∫(W/L)•xdx.
Then Work = ∫43.33x dx. From x = 0 to 7
After that Work = 43.33 ∫x dx.
Now Work = 43.33 x²/2. From x = 0 to 7
Work is = 21.66 [x²] from x = 0 to 7
Work is = 21.66 ( 7²-0²)
Then Work = 21.66 × 49
Hence Work = 1061.5 Joule
Therefore, The work done to lift the chain to 7m is 1061.5 J

Micah’s bicycle wheel has a radius of 14 inches. About how far will micah’s bicycle travel each time his wheel turns one full rotation?
Answer:
D. 88 inches
Step-by-step explanation:
to get the circumference of a circle the equation is C=2πr
C=87.96
Final answer:
Every time Micah's wheel turns one full rotation, the bicycle would travel approximately 88 inches.
Explanation:
The student's question relates to the travel distance of a bicycle wheel in one full rotation.
The distance traveled by a wheel in one rotation is equal to the circumference of the wheel, which is calculated by the formula:
Circumference = 2π × radius.
Given Micah's bicycle wheel has a radius of 14 inches, the calculation would be:
Circumference = 2 × π × 14 inches
Circumference = 2 × 3.1416 × 14 inches
Circumference ≈ 88 inches
Therefore, every full rotation of Micah’s 14-inch-radius bicycle wheel will result in the bicycle traveling approximately 88 inches, which is the circumference of the wheel.
The wind speed s (in miles per hour) is related to the distance (in miles) the tornado travels by the equation s = 93log d + 65. On March 18, 1925, a tornado whose wind speed was about 280 miles per hour struck the Midwest. How far did the tornado travel?
Answer:
The distance the tornado traveled was approximately 205 miles.
Step-by-step explanation:
The equation representing the relationship between the wind speed (in miles per hour) and the distance the tornado travels (in miles) is:
[tex]s=93\log d+65[/tex]
Compute the value of d for s = 280 as follows:
[tex]s=93\log d+65[/tex]
[tex]280=93\log d+65[/tex]
[tex]93\log d=280-65\\93\log d=215[/tex]
[tex]\log d=2.312\\[/tex]
[tex]d=10^{2.312}\\d=205.035\\d\approx 205[/tex]
Thus, the distance the tornado traveled was approximately 205 miles.

Complete the steps to find the area of the trapezoid.
Area of rectangle = _ square units
Area of triangle 1 = square units
Area of triangle 2 = _ square units
Area of triangle 3 = _ square units
Area of trapezoid = _ square units
Given:
In the given diagram
Each small box along X axis = 2 unit
Each small Box along Y axis = 2 unit
For rectangle:
Length = 16 unit
Width = 16 unit
For triangle 1
Base = 8 unit
Height = 6 unit
For triangle 2
Base = 8 unit
Height = 4 unit
For triangle 3
Base = 16 unit
Height = 12 unit
Formula
Area of the trapezoid is
[tex]A = R -T_{1} -T_{2} -T_{3}[/tex]
Where, [tex]A[/tex] be the area of the trapezoid
[tex]R[/tex] be the area of the rectangle
[tex]T_{1} ,T_{2} ,T_{3}[/tex] be the area of the triangle 1, 2 and 3 respectively.
[tex]R = lb[/tex] where, l be length and b the width
[tex]T_{1} = \frac{1}{2} bh[/tex], where, b be the base and h be the height
Now,
Taking, l = 16 and b = 16 we get,
[tex]R = (16)(16)[/tex] = 256 sq unit
For Triangle 1
Taking, b = 8 and h = 6 we get,
[tex]T_{1} = \frac{1}{2}(8)(6)[/tex] sq unit
[tex]T_{1} = 24[/tex] sq unit
For Triangle 2
Taking, b = 8 and h = 4 we get,
[tex]T_{2} = \frac{1}{2}(8)(4)[/tex] sq unit
[tex]T_{2} = 16[/tex] sq unit
For Triangle 3
Taking, b = 16 and h = 12 we get,
[tex]T_{3} = \frac{1}{2}(16)(12)[/tex] sq unit
[tex]T_{3} = 96[/tex] sq unit
Therefore,
The area of the trapezoid is = 256-24-16-96 sq unit = 120 sq unit
Hence,
Area of rectangle =256 square units
Area of triangle 1 = 24 square units
Area of triangle 2 = 16 square units
Area of triangle 3 = 96 square units
Area of trapezoid = 120 square units
Answer:
Area of rectangle =256 square units
Area of triangle 1 = 24 square units
Area of triangle 2 = 16 square units
Area of triangle 3 = 96 square units

A train station employee collects data on 160 incoming trains to the station. He notices that 18 of the 90 incoming trains on line A arrive late, and 14 of the 70 incoming trains on line B arrive late.
What is the probability that a train on line A arrives on time? What is the probability that any train arrives on time?
Answer:
Probability of a train on line A arriving on time: 80%
Probability of any train arriving on time: 96%
Step-by-step explanation:
If 18 of the 90 incoming trains on line A arrive late, we have that 90 - 18 = 72 trains of the 90 arrive on time, so the probability of a train on line A arriving on time is:
P(A) = 72/90 = 0.8 = 80%
on line B, we have that 70 - 14 = 56 trains of the 70 arrived in time, so the probability of a train from line B arriving on time is:
P(B) = 56/70 = 0.8 = 80%
To find the probability of any train arriving on time, we can use this formula:
P(A or B) = P(A) + P(B) - P(A and B)
P(A or B) = 0.8 + 0.8 - 0.8*0.8
P(A or B) = 1.6 - 0.64 = 0.96 = 96%
The probability that a train on line A arrives on time is 0.8 or 80%. The probability that any train arrives on time, considering both line A and line B, is also 0.8 or 80%.
Explanation:To calculate the probability that a train on line A arrives on time, we subtract the number of trains that arrive late from the total number of trains on line A:
Probability = (Total trains on line A - Trains on line A that are late) / Total trains on line A
Probability = (90 - 18) / 90
Probability = 72 / 90
Probability = 0.8 or 80%
To calculate the probability that any train arrives on time at the station, we need to consider the total number of trains arriving on time for both lines:
Total trains on time = (Total trains on line A - Trains late on line A) + (Total trains on line B - Trains late on line B)
Total trains on time = (90 - 18) + (70 - 14) = 72 + 56 = 128
Then, we divide the number of trains on time by the total number of trains:
Probability = Total trains on time / Total trains
Probability = 128 / (90 + 70)
Probability = 128 / 160
Probability = 0.8 or 80%
