Answer: 7.7%
Step-by-step explanation: First find the increase in height by subtracting 52 from 56. 56-52=4.
To find what percent this is of 52, divide 4 by 52. 4/52=0.0769. Then convert this from a decimal to a percent by multiplying by 100. 0.0769*100=7.69.
I just rounded it to the nearest tenth, you can change it how you need to.
Accuracy is how close a measured value is to the actual (true) value.
A=65
B=-75
C=-3
D=0
E=20,000
F=95
G=12
H=-12
Answer:
m is gradient = (-2+3)/(0+5)
= 1/5
use formula: y-y1( -2 or -3 ) = m( x - x1( 0 or -5 ) )
u will get answer: y = 1/5x - 2
Jackson's method to figure out the height of the mountain is from the
similar triangles formed by the light using the mirror.
Response:
- The height of the mountain is <u>50 feet 8 inches</u>
<h3>Which methods can used to find the height of the mountain?</h3>
The given parameters are;
Distance of the mirror from Jackson = 5 feet
Distance of the mirror from the base of the mountain = 40 feet
Height of Jackson = 6'4'' tall
Required:
The approximate height of the mountain, <em>h</em>
Solution:
The triangles formed by the light from the top of the mountain which is
reflected to Jackson from the mirror, Jackson's height, the height of the
mountain, and their distances from the mirror, are similar triangles.
The ratio of corresponding sides of similar triangles are equal, therefore,
we have;
![\dfrac{Jackson's \ height}{Jackson's \ distance \ from \ the \ mirror } =\mathbf{ \dfrac{Height \ of \ the \ mountain}{Distance \ of \ the \ mountain \ from \ the \ mirror}}](https://tex.z-dn.net/?f=%5Cdfrac%7BJackson%27s%20%5C%20height%7D%7BJackson%27s%20%5C%20distance%20%5C%20from%20%5C%20the%20%5C%20mirror%20%7D%20%3D%5Cmathbf%7B%20%5Cdfrac%7BHeight%20%5C%20of%20%5C%20the%20%5C%20mountain%7D%7BDistance%20%5C%20of%20%5C%20the%20%5C%20mountain%20%5C%20from%20%5C%20the%20%5C%20mirror%7D%7D)
Which gives;
![\dfrac{6\frac{1}{3} \, ft.}{5 \, ft.} = \mathbf{ \dfrac{h}{40 \, ft.}}](https://tex.z-dn.net/?f=%5Cdfrac%7B6%5Cfrac%7B1%7D%7B3%7D%20%5C%2C%20ft.%7D%7B5%20%5C%2C%20ft.%7D%20%3D%20%5Cmathbf%7B%20%5Cdfrac%7Bh%7D%7B40%20%5C%2C%20ft.%7D%7D)
![h = 480 \, in. \times \dfrac{76 \, in.}{60 \, in.} = 608 \, in. = \mathbf{50 \frac{2}{3} \, ft. = 50 \, feet \ 8 \, inches}](https://tex.z-dn.net/?f=h%20%3D%20480%20%5C%2C%20in.%20%5Ctimes%20%5Cdfrac%7B76%20%5C%2C%20in.%7D%7B60%20%5C%2C%20in.%7D%20%3D%20608%20%5C%2C%20in.%20%3D%20%5Cmathbf%7B50%20%5Cfrac%7B2%7D%7B3%7D%20%5C%2C%20ft.%20%3D%2050%20%5C%2C%20feet%20%5C%208%20%5C%2C%20inches%7D)
- The height of the mountain is approximately <u>50 feet 8 inches</u>
