Answer:\sqrt{155}

Step-by-step explanation:

Oh god pythagorean triples got thrown out the window for this one. This will be a bit ugly.

First, we find the other side length of the rectangle using the pythagorean theorem.

Then, we use that side length in ANOTHER pythagorean theorem to get our answer.

Well, we know that the side length is \sqrt{5^{2}+9^{2} }

We'll use whatever that number is, let's call it x for now, in our other expression:

\sqrt{x^{2}+7^{2}}

So we can do this in one clean equation by substituting our first equation as x in the second one.

Or do them separately. Your choice.

Anyways, try to solve this one now that you know what to do. If you need more help then message.

snow_lady [41]

Answer:

a+b+c+d = -5\cdot b

Step-by-step explanation:

The given system of equations is now reduced:

1) a+b = c, b+c = d, c+d=a, b > 0 Given

2) a = c+d By 1)

3) (c+d)+b=c 2) in 1)

4) d = b + c By 1)

5) [c+(b+c)]+b = c 4) in 3)

6) 2\cdot b + 2\cdot c = c Algebra

7) c = -2\cdot b Algebra

8) d = -b 7) in 4)/Algebra

9) a = -3\cdot b 7) and 8) in 2)/Algebra

10) a+b+c+d = -5\cdot b 9), 1), 7) and 8)/Algebra/Result

Daniel runs 40/5 miles in 124/₁ minutes. What is the unit rate in terms of miles per minute? What the answer:
sasho [114]

Using the given information, the unit rate is 0.0645 miles/minute

<h3>Calculating rate </h3>

From the question, we are to determine the unit rate

From the given information,

Daniel runs 40/5 miles in 124 minutes

That is,

Distance = 40/5 miles = 8 miles  

Time = 124 minutes

Using the formula,

Rate = Distance / Time

Rate = 8 miles / 124 minutes

Rate = 0.0645 miles/minute

Hence, the unit rate is 0.0645 miles/minute
