The expression m divided by 4 is teh distance each person runs in a relay race that is m miles. How far does each person run in

Dovator [93]

Answer:

Each person runs 3 miles in a relay race.

Step-by-step explanation:

Given:

Distance of Relay race m = 12 miles.

The expression m divided by 4 is the distance each person runs in a relay race that is m miles.

Each person runs in relay race = $\frac{m}{4}$

Now given the total distance of the relay race is 12 miles.

i.e. value of m = 12 miles

Now substituting the value of m in above equation we get;

Each person runs in relay race = $\frac{m}{4} = \frac{12}{4}=3 \ miles$

Hence each person runs 3 miles in a relay race.

15 points !!!! Diameter Radius Area Circumference of 84mm

SSSSS [86.1K]

Answer:

$lets \: \: \: find \: \: the \: \: radius \\ = 2\pi \: r \\ = 2\pi \: r = 84 \\ = \frac{2\pi \: r}{2\pi } = \frac{84}{2\pi} \\ = r = 13.37mm$

$lets \: \: \: find \: \: the \: \: \: area \\ = \pi {r}^{2} \\ = \pi \times {13.37}^{2} \\ = 561.55 {mm}^{2}$

$lets \: \: \: find \: \: \: the \: \: diameter \\ = d = 2r \\ = d = 2 \times 13.37 \\ = d = 26.74mm$
