As part of an annual fundraiser to help raise money for diabetes research, Diane joined a bikeathon. The track she biked on was

Lyrx [107]

Answer:

$38.5\,\text{laps}\times\dfrac{1920\,\text{yd}}{1\,\text{lap}}\times\dfrac{3\,\text{ft}}{1\,\text{yd}}\times\dfrac{1\,\text{mi}}{5280\,\text{ft}}$
42 miles

Step-by-step explanation:

You know that fractions with the same value in numerator and denominator reduce to 1. This is true whether the value is a number, a variable expression, or some mix of those. That is ...

$\dfrac{1760}{1760}=1\\\\\dfrac{3\,\text{mi}}{1\,\text{mi}}=\dfrac{3}{1}\cdot\dfrac{\text{mi}}{\text{mi}}=3$

This example should show you that you can treat units as if they were a variable.

So, the unit conversion process is the process of choosing combinations of numerator and denominator units so that all the units you don't want cancel, leaving only units you do want.

You're starting with a number than has "laps" in the numerator. To cancel that, you need to find a conversion factor with "lap" in the denominator. On the list you are given, the one that has that is ...

$\dfrac{1920\,\text{yd}}{1\,\text{lap}}$

Now, you have canceled laps, but you have yards. Also on your list of conversion factors is a ratio with yards in the denominator:

$\dfrac{3\,\text{ft}}{1\,\text{yd}}$

This will cancel the yards in the numerator from the previous result, but will give you feet in the numerator. You want miles, so you look for a conversion factor between feet and miles, with miles in the numerator. The one you find is ...

$\dfrac{1\,\text{mi}}{5280\,\text{ft}}$

These three conversion factors go into the blanks. When you form the product, you will get ...

$\dfrac{38.5\cdot 1920\cdot 3}{1\cdot 1\cdot 5280}\cdot\dfrac{\text{laps$\cdot$yd$\cdot$ft$\cdot$mi}}{\text{lap$\cdot$yd$\cdot$ft}}=42\,\text{mi}$

a vendor is thinking about changing the number of sweatshirts he brings to tan event. to make sure he doesn't run out, he plans

NISA [10]

The sweatshirt size which the vendor should bring more of by virtue of that which is most likely to be sold is; Choice A; Extra-large.

<h3>Which sweatshirt size should the vendor bring more of?</h3>

If follows from the task content that the

ratio of extralarge shirts sold relative to the quantity he had to sell is

= 99/108

= 11/12,

This is a ratio which is larger than any other shirt.

Consequently, the vendor must bring more of the X-large shirts to avoid running out of them.
