A runner runs 8 miles in 92 minutes what is the runner’s unit rate?

Mathematics

Answer:

The runner's unit rate is 0.09 miles/minute.

Step-by-step explanation:

Given:

Distance cover by runner = 8 miles and the time taken = 92 minutes.

Now, to calculate the runner's unit rate.

We put the formula to get the unit rate:

Velocity = distance/time

v=\frac{d}{t}

v=\frac{8}{92}

v=0.0869

v = 0.09 miles/minute (approximately)

Therefore, the runner's unit rate is 0.09 miles/minute.

What is (n+2) / -8=-4
Travka [436]

\frac{n +2}{-8} =-4      Multiply -8 on both sides

\frac{n +2}{-8} (-8)=-4(-8)

n + 2 = 32       Subtract 2 on both sides

n + 2 - 2 = 32 - 2

n = 30

40 POINTS Geometry homework
kicyunya [14]

\angle{DBC   }=(5x+4)°

\angle{ A  }=(2x-2)°

\angle{C   }=(4x-6)°

we know that,

\angle{DBC}=\angle{A}+\angle{C}

According to the question,

\tt{ 5x+4=2x-2+4x-6  }

\tt{ 5x+4=6x-8  }

\tt{ 6x-5x=4+8  }

\blue{x=12   }

so,

\angle{C }=(4x-6)°=(4×12-6)°=(48-6)°=42°

Which is a counterexample that disproves the conjecture? After completing several multiplication problems, a student concludes t
Dahasolnce [82]
When you make the product of a binomial of the kind x + a times other binomial that is of the kind x - a, you obtain another binomial (not a trinomial), so any example with that form will be a counterexample that disproves the conjecture:

(x + a) * (x - a) = x^2 - a^2

For example, (x +3) * (x - 3) = x^2 - 9. So, not always the product of two binomials is a trinomial.

Answer:

The answer to your question is: midsegment = 35 units

Step-by-step explanation:

Use the Thales' theorem

                          \frac{3x + 55}{6x + 5} = \frac{86}{43} \\

                          43( 3x + 55) = 86( 6x + 5)

                          129x + 2365 = 516x + 430

                          129x - 516x = 430 - 2365

                          -387x = -1935

                           x = -1935 / -387

                           x = 5

Midpoint length = 6(5) + 5

                           = 30 + 5

                          = 35 units
