Answer: Only j = 2

============================================

Explanation:

Let's solve for j

\frac{96}{j} \ge 40\\\\96 \ge 40j\\\\\frac{96}{40} \ge j\\\\2.4 \ge j\\\\j \le 2.4

In the second step, I multiplied both sides by j. If j is a positive number, then the inequality sign will not flip. All of the answer choices are positive numbers, so we don't have to worry about the inequality sign flipping.

The last step shows that j = 2.4 or j < 2.4

So j is 2.4 or smaller.

Of the list given to us, only j = 2 fits the description, since something like j = 8 is not 2.4 or smaller.

---------------------------

If j = 2, then,

\frac{96}{j} \ge 40\\\\\frac{96}{2} \ge 40\\\\48 \ge 40\\\\

which is a true statement since 48 is larger than 40. This shows that j = 2 is a solution.

Something like j = 8 does not work because

\frac{96}{j} \ge 40\\\\\frac{96}{8} \ge 40\\\\12 \ge 40\\\\

which is false because 12 is not equal to 40 or larger than 40. This means j = 8 is not a solution. You should find that j = 12 and j = 3 lead to similar false statements.

Of the list given, j = 2 is the only solution.

<h2><u>Answer:</u></h2><h2><u></u>\boxed{\boxed{\sf{j=2}}}<u></u></h2><h2><u></u></h2><h2><u>Solution Steps:</u></h2>

______________________________

<h3>1.) Solve using j = 12:</h3>
  • Plug in 12: \frac{96}{12} ≥ 40
  • Divide 96 by 12: =8
  • Compare: 8 ≥ 40

So this is False.

<h3>2.) Solve using j = 8:</h3>
  • Plug in 8: \frac{96}{8} ≥ 40
  • Divide 96 by 8: =12
  • Compare: 12 ≥ 40

So this is False.

<h3>3.) Solve using j = 2:</h3>
  • Plug in 2: \frac{96}{2} ≥ 40
  • Divide 96 by 2: =48
  • Compare: 48 ≥ 40

So this is True.

<h3>4.) Solve using j = 3:</h3>
  • Plug in 3: \frac{96}{3} ≥ 40
  • Divide 96 by 3: =32
  • Compare: 32 ≥ 40

So this is False.

If you triple 4 and subtract to each day how many days until you have zero
Mrrafil [7]
Do you mean subtract two each day? If so...
4x3=12 and 12 divided by 2 is 6 so it would take six days to reach zero
or
you could manually subtract two from 6 each days as in 12-2=10 (1 day), 10-2=8 (2 days), and so on...

Find the oth term of the geometric sequence 7, 14, 28, ...
yaroslaw [1]

Answer:

The nth term of the geometric sequence 7, 14, 28, ... is:

a_n=7\cdot \:2^{n-1}

Step-by-step explanation:

Given the geometric sequence

7, 14, 28, ...

We know that a geometric sequence has a constant ratio 'r' and is defined by

a_n=a_1\cdot r^{n-1}

where a₁ is the first term and r is the common ratio

Computing the ratios of all the adjacent terms

\frac{14}{7}=2,\:\quad \frac{28}{14}=2

The ratio of all the adjacent terms is the same and equal to

r=2

now substituting r = 2 and a₁ = 7 in the nth term

a_n=a_1\cdot r^{n-1}

a_n=7\cdot \:2^{n-1}

Therefore, the nth term of the geometric sequence 7, 14, 28, ... is:

a_n=7\cdot \:2^{n-1}

Choose the ratio that you would use to convert 0.5 miles to yards. Remember that there are 1,760 yards in one mile.
zavuch27 [327]
Hello there, and thank you for posting your question here on brainly.

So, you need to find the ratio of the following to figure out which one is how to find how many yards are in half a mile.

What would you need to do to find out how? Divide it.

So you'd divide it by what? 2.

Which is the result? C. 880 yd / 1 mi

Hope this helped!! ☺♥
