It is 45 yd from the base of the pole.
The pieces of the right triangle we are given are one of the legs (the height of the pole, 60 yd) and the hypotenuse (the length of the cable, 75 yd). Using the Pythagorean theorem, we have:
60²+b²=75²
3600+b²=5625
Subtract 3600 from both sides:
3600+b²-3600=5625-3600
b²=2025
Take the square root of both sides:
√(b²) = √2025
b = 45
Answer:
count that many 9s by the number your multiplying by.
Step-by-step explanation:
so example think of it like this =
9 x 9
9 + 9 + 9 + 9 + 9 + 9 + 9 + 9 + 9 = 81
9 x 9 = 81
that easy ! just add the amount of 9s to the number your multiplying by . if u still need help, go on You Tube and search MathAntics .. he explains every different types of math amazing !
Let <em>V</em> be the volume of the tank. The inlet pipe fills the tank at a rate of
<em>V</em> / (5 hours) = 0.2<em>V</em> / hour
and the outlet pipe drains it at a rate of
<em>V</em> / (8 hours) = 0.125<em>V</em> / hour
With both valves open, the net rate of water entering the tank is
(0.2<em>V</em> - 0.125<em>V </em>) / hour = 0.075<em>V</em> / hour
If <em>t</em> is the time it takes for the tank to be full, then
(0.075<em>V</em> ) / hour • <em>t</em> = <em>V</em>
Solve for <em>t</em> :
<em>t</em> = <em>V</em> / ((0.075<em>V</em> ) / hour)
<em>t</em> = 1/0.075 hour
<em>t</em> ≈ 13.333 hours
