1. Part 1) [tex]80\frac{beats}{minute}[/tex]

   Part 2) [tex]423 \frac{miles}{hour}[/tex]

   Part 3) Bag A [tex]10[/tex] ounces for [tex]\$1.10[/tex]

   Part 4) [tex]320\ words[/tex]

   Part 5) [tex]420\ miles[/tex]

   Step-by-step explanation:

   we know that

   A Unit Rate is the ratio of two measurements in which the second term is equal to one

   Part 1)

   [tex]80\frac{beats}{minute}[/tex]

   rewrite

   [tex]80\frac{beats}{minute}=\frac{80}{1}\frac{beats}{minute}[/tex]

   the second term is equal to one

   therefore

   Is a unit rate

   Part 2) To find the unit rate divide the total miles by the total hours

   so

   [tex]\frac{1,269}{3}\frac{miles}{hours}=423 \frac{miles}{hour}[/tex]

   Part 3)

   Find the unit price of each bag

   Bag A -------> [tex]\frac{1.10}{10}\frac{\$}{ounces}=0.11\frac{\$}{ounce}[/tex]

   Bag B -------> [tex]\frac{1.38}{12}\frac{\$}{ounces}=0.115\frac{\$}{ounce}[/tex]

   Bag C -------> [tex]\frac{0.84}{6}\frac{\$}{ounces}=0.14\frac{\$}{ounce}[/tex]

   The best buy is the bag A ( is the smallest unit price)

   Part 4) we know that

   Samantha types [tex]40[/tex] words per minute

   so

   by proportion

   Find how many words type in [tex]8[/tex] minutes

   [tex]\frac{40}{1}\frac{words}{minute}=\frac{x}{8}\frac{words}{minutes}\\ \\x=8*40\\ \\x=320\ words[/tex]

   Part 5) How many miles can a car travel on [tex]15[/tex] gallons of gas if it travels [tex]28[/tex] miles on 1 gallon of gas

   by proportion

   [tex]\frac{28}{1}\frac{miles}{gallon}= \frac{x}{15}\frac{miles}{gallons}\\ \\x=15*28\\ \\x=420\ miles[/tex]

3. 1 - C) 80 beats / min

   2 - 1269/3 = 423 mph [ Option D ]

   3 - Bag A

   4 - 40 * 8 = 320 [ Option C ]

   5 - 28 * 15 = 420 [ Option D ]
   Hope this helps!

4. What is 15 times 28?

5. Your answer would be (D) 420

   To find this you multiply the miles it can travel in 1 mile by the amount of gallons it has.

   Hope this helps!
