Answer:

h=h= \frac{5R^{3} }{LU}

Step-by-step explanation:

1.) You must isolate the h from the equation by dividing both sides by L (or multiply by its reciprocal, which in this case, the reciprocal on L is \frac{1}{L}    .....So it would look like:

(\frac{1}{L} )*\frac{5R^{3} }{U} = \frac{L}{h}* (\frac{1}{h} )\\

2.) Simplify the equation if you need to (in this case, its not needed)

\frac{5R^3}{LU} =h

That's your answer :)

A map of your town has a scale of 1 inch to 0.25 mile. There are two roads that are 5 inches apart on the map. Use this informat
egoroff_w [7]

Answer: <u>The 2 roads are 1.25 miles apart.</u>

Step-by-step explanation:

If 1 inch equals .25 miles, then you need to multiply .25 by 5.

Use proportions. Make sure the miles are on the same "side" of the fraction. Side meaning the top or the bottom

\frac{1}{.25} =\frac{5}{x}

1 times X equals 1x

.25 times 5 equals 1.25

1.25 divided by 1 equals 1.25.

A right triangle has one leg that measures 7 inches and the hypotenuse measures 12 inches.
kirill [66]
  • Hypotenuse=H=12in
  • Perpendicular=P=7in
  • Base=B=?

Using Pythagorean theorem

\boxed{\sf B^2=H^2-P^2}

\\  \sf \longmapsto \: b =  \sqrt{ {h}^{2}  -  {p}^{2} }  \\  \\  \sf \longmapsto \: b =  \sqrt{ {12}^{2}  -   {7}^{2} }  \\  \\  \sf \longmapsto \: b =  \sqrt{100 - 49}  \\  \\  \sf \longmapsto \: b =  \sqrt{51}  \\  \\  \sf \longmapsto \: b = 7.2in
