Zinaida [17]

Answer:

d = 16.3 ft

Step-by-step explanation:

This is a right triangle, so we can use the Pythagorean theorem

a^2 +b^2 = c^2

where a and b are the legs and c is the hypotenuse

d^2 + 24^2 = 29^2  where d is the distance

d^2 +576 = 841

Subtract 576 from each side

d^2 +576-576 = 841-576

d^2 =265

Take the square root of each side

sqrt(d^2) = sqrt(265)

d = sqrt(265)

d =16.2788206

To the nearest tenth

d = 16.3 ft

A circular jogging track forms the edge of a circular lake that has a diameter of 2 miles. Johanna walked once around the track
harkovskaia [24]

Answer:

  C.  2.0 < t < 2.5

Step-by-step explanation:

  time = distance / speed

The circumference of the lake is given by ...

  C = πd = 2π miles ≈ 6.28 miles

Then Johanna's time is ...

  (6.28 mi)/(3 mi/h) ≈ 2.09 h

This time is in the interval (2, 2.5), so matches choice C.

___

<em>Alternate solution</em>

If we take pi to be 3, then this boils down to ...

  2×3/3 = 2 . . . hours

Pi is on the order of 5% more than 3, so her time will be on the order of 5% more than 2 hours, or just above 2, but not as great as 2.5 hours. This sort of estimating can get you to the correct answer without a calculator.
