scale factor=shadow: real figure
s.f=4:6
=2:3
applying the same to the pole
let x be the real height of the pole.
2:3=20/x
3×20=2x
60=2x
60/2=2x/2
x=30feet
60 divided by 12 = 5
The width is 5 and length is 12
The width is 5 because the formula for area is Length x Width =Area
In this case 60 = 12 x W.
So, 60/12 = W
Answer: two over three
Step-by-step explanation:
![y=ax+b](https://tex.z-dn.net/?f=y%3Dax%2Bb)
line intercepts y at (0,-2)
Therefore, ![y=ax-2](https://tex.z-dn.net/?f=y%3Dax-2)
Substitute x = 3 in y =ax-2
![y=3a-2](https://tex.z-dn.net/?f=y%3D3a-2)
To find the x-intercept, y = 0
![3a-2=0\\3a=2\\a=\frac{2}{3}](https://tex.z-dn.net/?f=3a-2%3D0%5C%5C3a%3D2%5C%5Ca%3D%5Cfrac%7B2%7D%7B3%7D)
The slope is 2/3
y-intercept is -2
So two over three
Answer:
Step-by-step explanation:
since the data is already arranged in ascending to descending u don't have to change.
upper quartile (Q3) = 3(n + 1)/4 (n means no of data)
=3(10 + 1)/4
=3*11/4
=33/4
=8.25
=8 th term + 0.25(9 th term - 8 th term)
=11 + 0.25(13 - 11)
=11 + 0.25*2
=11 + 0.5
=11.5
