An eagle can fly at a speed of 50 mph and a starling can fly at 78 mph. How far will the starling fly in the time it takes the e

disa [49]

Well, we know the eagle does 50 miles in 1hr, how long will it be for 125 miles?

well $\bf \begin{array}{ccllll}
miles&hours\\
\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\
50&1\\
125&x
\end{array}\implies \cfrac{50}{125}=\cfrac{1}{x}\implies x=\cfrac{125\cdot 1}{50}
\\\\\\
x=\cfrac{5}{2}$

so, the eagle for 125miles does them in 5/2 hours or 2hrs and a half

now, how far will the sterling go in 2hrs and a half?

well, we know the sterling does 75 miles in 1hr

thus $\bf \begin{array}{ccllll}
miles&hours\\
\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\
75&1\\
x&\frac{5}{2}
\end{array}\implies \cfrac{75}{x}=\cfrac{1}{\frac{5}{2}}\implies \cfrac{75}{x}=\cfrac{2}{5}$

solve for "x"

a non-regular Pentagon has 3 sides that are the same length. the 4th side is 6 inches longer than the length shared by 3 of the

OlgaM077 [116]

Answer:

15 inches

Step-by-step explanation:

Okay, so we know a pentagon has 5 sides total. We also know that 3 of the sides are the same length, so let's assume those sides are n length.

n + n + n + _ + _ = 4ft 11in

The fourth side is an inch less than n.

n + n + n + (n - 1inch) + _ = 4ft 11in

The last side is 6inches more than n.

n + n + n + (n - 1inch) + 9n + 6inches) = 4ft 11in

Now that we have out equation, lets convert the 4ft 11in into just inches. 4ft = 4 x 12 inches (48 inches). Then add the 11inches and you get 59.

Now our equation is in terms of inches,

we can combine the 3 ns to 3n.

3n + (n-1) + (n +6) + 59

Then we combine all the ns and get 6n -1 +6 =59

Simplify to 6n +5 =59

then to 6n = 54

Then to n = 9.

Since we are looking for the longest side, you have to substitute n in for the side that would have the longest measure, n + 6.

9 + 6 = 15.

15 inches is your answer.
