a street that is 116 meters long is covered in snow city workers are using a snow plow to clear the street a tire on the snow pl
Yuri [45]
So, we know the snow plow tire turned or went around 29 times, namely 29 revolutions, and recall that one revolution is a 2π angle in radians.

since the tire went around 29 times, so it made an angle of 29 * 2π, or 58π.

we know the street is 116 meters long, namely "an arc made by that 58π angle is 116".

\bf \textit{arc's length}\\\\
s=r\theta ~~
\begin{cases}
r=radius\\
\theta =angle~in\\
\qquad radians\\
------\\
s=116\\
\theta =58\pi 
\end{cases}\implies 116=r58\pi \implies \cfrac{116}{58\pi }=r
\\\\\\
\cfrac{2}{\pi }=r\qquad \qquad\qquad \qquad  \stackrel{\textit{a \underline{d}iameter is twice the radius}}{2\left( \cfrac{2}{\pi } \right)=d\implies \cfrac{4}{\pi }=d}

Nat2105 [25]

Answer:

The speed was 61\frac{miles}{hour}

Step-by-step explanation:

we know that

The speed is equal to divide the distance by the time

Let

s------> the speed in miles per hour

d ----> the distance in miles

t ----> is the time in hours

we know that

s=\frac{d}{t}

we have

d=305\ miles

t=5\ hours

substitute

s=\frac{305}{5}

s=61\frac{miles}{hour}

(-3,0),(5,-2) find the slope
Mashcka [7]

Answer:

-4

Step-by-step explanation:

Point slope form: y - y = m (x - x)

5 - (-3) = m (-2 - 0)

5 + 3 = m (-2)

8 = m (-2)

m = 8/(-2)

m=4
