Answer: It is worth it.

Step-by-step explanation:

If a customer sends 101 - 200 texts in a month, they get charged 8 cents per text.

If they send 201 - 300, they get charged 6 cents per month.

If you have sent 200 texts, your charge for the month will therefore be:

= 200 * 8

= $16.00

If you send the 201th text, you will be charged 6 cents per text. Total charge would be:

= 201 * 6

= $12.06

<em>If you send 1 more text, it will be worth it because you will save:</em>

<em>= 16 - 12.06</em>

<em>= $3.94</em>

Which of the following is equivalent to (5)^7/3
kifflom [539]
<em>The answer is \sqrt[3]{ 5^{7} }</em>

The reason we get this answer is because when you are converting from exponential form, to radical form you always place the numerator as our constant's exponent in the radical <em>( 5^{7} is called the radicand because it is located in the radical)</em> and the denominator in front of the radical, where it would be called the index. 

<em>Here's what a formula would look like:</em> ( \sqrt[n]{x} ) ^{q}=x^{ \frac{p}{q} }

Thank you for your question! I hope this helped! Have an amazing day and feel free to let me know if I can help you further! :D

The distance between my house and Memphis is 150 km. If I drive in my car, it takes me 72 min to make the first 100 km of the dr
Cloud [144]

Set up a ratio:

You drove 72 minutes and 100 km = 72/100

You want the number of minutes (x) to drive 150 km = x/150

Set the ratios to equal each other and solve for x:

72/100 = x/150

Cross multiply:

(72 * 150) = 100 * x)

Simplify:

10,800/100x

Divide both sides by 100:

x = 10800/100 = 108

This means it would take 108 minutes to drive 150 km.

Now subtract the time you have already driven to fin how much more you need:

180 - 72 = 36 more minutes.
