Josie's height = 5 ft 6 in. = 5 1/2 ft = 11/2 ft.
Josie's shadow = 6 ft.
Ratio of shadow to height = 6 / 11/2 = 12/11
So, It would be equal to ratio of building's shadow to building's height.
18/x = 12/11
x = 18*11 /12
x = 3*11 / 2
x = 16.5
In short, Your Answer would be 16.5 Feet
Hope this helps!
Answer:
subtract 3
Step-by-step explanation:
You want to "undo" what is done to x. It usually works well to do that in reverse order. Here, x is ...
- multiplied by 2
- had 3 added to the product
To undo these steps, you start by undoing the addition of 3.
__
1st step: subtract 3 from both sides.
2nd step: divide both sides by 2
_____
As with equations, whatever you do to one side of the inequality must also be done to the other side. When we say "subtract 3", we mean "subtract 3 from both sides of the inequality."
Answer:
The desviation is 8 4/7 or 8.571
Step-by-step explanation:
The conversion for any variable X to a standard z is
where mu is the mean and sigma de desviation
You can find the value of Z whith the tables of the accumulated probability function. The accumulated probability for the mean is 0.5 .Remenber that the accumlated probability function represent the area at the left of an abscissa. Then
0.5+0.3531=0.8531
Acording to the accumulated probability function table, a Z=1.05 has an area of 0.8531 at its left.
Now it is only solving the equation
σ=
σ=8.571
