=2/3 x 4 1/5
Change 4 1/5 to improper fraction
=2/3 x 21/5
Multiply the two numerators together and multiply the two denominators together
= (2*21)/(3*5)
=42/15
Convert back to mixed fraction
= 2 12/15
Simplify by dividing 3 into top & bottom
ANSWER:
= 2 4/5 simplest mixed fraction
Hope this helps! :)
All you need to do is divide 6.64 and 1.35. you would get 4.91851852. But, you need to round to the nearest tenth so it would actually be 4.9.
See picture below for a geometric view.
Let x = height of building
We use basic trigonometry to find x.
The tangent function = opposite side of right triangle OVER adjacent side of right triangle.
tan(2°) = x/1
Solve for x.
After multiplying both sides by 1 (here 1 represents 1 mile), we get
tan(2°) = x.
We now use the calculator to find x.
In fact, you can take it from here. Use your calculator.
I believe it’s x=2.5 or x=2 1/2 or x=5/2
They are all the same answers in different forms . Hope it’s right
