The most accurate determination for the number of 45.36 feet per second Tyrone traveled on his way to work.

Given that,

Using a stopwatch Tyrone determines it takes him 58.2 minutes to travel 30 miles to work the stopwatch measures to hundredths of a minute going by the accuracy of the stopwatch.

We have to determine,

Which is the most accurate determination for the number of feet per second Tyrone traveled on his way to work?

According to the question,

Tyrone determines it takes him 58.2 minutes to travel 30 miles to work,

the stopwatch measures to hundredths of a minute going by the accuracy of the stopwatch are determined by,

\rm  Speed = \dfrac{Distance}{Time}

Substitute the values in the equation,

\rm  Speed = \dfrac{Distance}{Time}\\\\Speed = \dfrac{30}{58.2}\\\\Speed = \dfrac{50}{97}  \ miles \ per \ minute

If 1 mile = 5,280 feet, then his speed is,

\rm  Speed = \dfrac{50}{97}  \ miles \ per \ minute\\\\  Speed = \dfrac{50}{97}  \times 5280 \\\\ Speed= \dfrac{26,400}{97}\ feet \ per \ minute\\

And 1 minute = 60 seconds, then his speed is,

\rm  Speed= \dfrac{26,400}{97}\ feet \ per \ minute\\\\ Speed= \dfrac{26,400}{97} \times \dfrac{1}{60} \\\\ Speed = \dfrac{4400}{97} \ feet \ per \ second \\\\ Speed = 45.36 \ feet \ per \ second

Hence, The most accurate determination for the number of 45.36 feet per second Tyrone traveled on his way to work.

How many millimeters are there in 16 meters
Anika [276]
One of the very nice features of the metric system of measurements is that there is a set of standardized prefixes that can be applied to any of the units. Some of the more common ones are
.. micro- . . . one millionth
.. milli- . . . . one thousandth
.. centi- . . . .one hundredth
.. kilo- . . . . .one thousand

Thus, one millimeter is 1/1000 = 0.001 meter. There are 1000 of them in 1 meter, so
.. 16 m = 16000 mm

AVprozaik [17]

Answer:

12 minutes

Step-by-step explanation:

 <u>50 miles</u>      =    <u>10 miles</u>                  << Equivalent

   1 hour        =          x                        <<   fraction

You divide 50 by 5 to get 10,

so to get the number of minutes for 10 miles,

divide 60 by 5.

(1 hour =  60 minutes, 60/5 = 12)

The two angles are verticals angles so they are congruent, so you can solve for x by writing and solving an equation

6x-82=3x-23

Combine like terms

3x=105

And simplify to get x=35
