A circular race track has a radius of 200 feet a car drives 50 laps around the track approximately how many miles does the car t
bazaltina [42]

Answer:

  11.9 miles

Step-by-step explanation:

The length of the track is ...

  C = 2πr = 2π(200 ft) = 400π ft

Then the length of 50 laps will be ...

  50C = 50·(400π ft) = 20,000π ft ≈ 62,831.9 ft

The number of miles (m) this is can be found from ...

  m(5280 ft) = 62,831.9 ft

  m = 62,831.9/5280 ≈ 11.90 . . . . miles

50 laps is about 11.9 miles.

Which of the following is equivalent to –(–5.25) ? 5 5.25 –5 –5.25<br>please answer fast​
Marina86 [1]

Answer:

The equivalent to -(-5.25) = 5.25

Step-by-step explanation:

Given

-(-5.25)

We need to determine the equivalent to -(-5.25)

some of the sign rules are:

+(+) = +      

−(−) = +

+(−) = -

−(+) = -

Thus,

-(-5.25)

Applying the rule: -a(-a) = a

=5.25

Therefore, the equivalent to -(-5.25) = 5.25
