- For situation one it would no
\frac{28}{4}  = 7
✔ Situation 2 would be yes
\frac{14}{4 }  =  \frac{7}{2}
- Situation 3 would be no
\frac{7.50}{10}  = 0.75 =  \frac{ 3}{4}
- Situation 4 would be no
\frac{1.50}{2}  = 0.75 =  \frac{3}{4}

Answer:

Sara runs an average of fourteen miles every four days.

A recipe calls for 3 1/2 cups of flour for every 1 cup of sugar.

Step-by-step explanation:

<em>Determine which of the following situations can be modeled by the ratio 7/2.</em>

  • <em>For every twenty-eight cats, there are 4 four dogs.</em> NO. The ratio of cats to dogs is 28/4 = 14/2.
  • <em>Sara runs an average of fourteen miles every four days.</em>  YES. The ratio of miles to days is 14/4 = 7/2.
  • <em>An online clothing store charges $7.50 to ship ten clothing items.</em> NO. The ratio of price to items is 7.50/10 = 0.75/1 = 1.50/2.
  • <em>A recipe calls for 3 1/2 cups of flour for every 1 cup of sugar.</em>  YES. The ratio of cups of flour to cups of sugar is 3.5/1 = 7/2.
  • <em>Bottled water is on sale this week for a rate of $1.50 for two bottles.</em> NO. The ratio of price to bottles is 1.50/2.

Write the next three terms of the arithmetic sequence.
JulijaS [17]

The next three terms are: 1/6 , 0 and -1/6

Step-by-step explanation:

Given sequence is:

\frac{5}{6} , \frac{2}{3} ,\frac{1}{2}, \frac{1}{3} ...

First of all, we have to find the common difference

here\\a_1 = \frac{5}{6}\\a_2 = \frac{2}{3}\\a_3 = \frac{1}{2}\\a_4 = \frac{1}{3}\\d = a_2-a_1 = \frac{2}{3} -\frac{5}{6} = \frac{4-5}{6} = -\frac{1}{6}\\d = a_3 - a_2 = \frac{1}{2} - \frac{2}{3} = \frac{3-4}{6} = =\frac{1}{6}

The common difference is -1/6

We can simply add -1/6 to the previous term to find the next terms so,

Adding -1/6 to 1/3

\frac{1}{3} - \frac{1}{6} = \frac{2-1}{6} = \frac{1}{6}\\\frac{1}{6} - \frac{1}{6} = 0\\0-\frac{1}{6} = -\frac{1}{6}

Hence,

The next three terms are: 1/6 , 0 and -1/6
