<h2>Answer:</h2>

All are irrational numbers

<h2>Explanation:</h2>

In mathematics an Irrational number is defined as any number that cannot be written as a complete ratio of two integers. An irrational number cannot be fully written down in decimal form. It would have an infinite number of digits after the decimal point. All the given numbers have un-ended numbers after the decimal point so they are irrational numbers.

C(squared)L(squared) + 100v(squared) = 100c(squared)<br>I have to solve for L
jeyben [28]
First subtract 100v² from both sides to get:

C²L²=100c²-100v²

Then divide both sides by C²:

L²=(100c²-100v²)/C²

Then take the square root of both sides:

L=+ or - the square root of (100c²-100v²)/C²

9. YOU BE THE TEACHER Your friend
Crank

Answer:

Step-by-step explanation:

Yes, it's reasonable.

What you are doing is solving the question by rounding. You come up with an answer. Suppose you loose the decimal somewhere and you get 0.36? Is that reasonable? Do you just write the answer in the provided blank and move on. What now?

You get it wrong?!!

But your estimate should be about 9/3 = 3. Now you look at your calculator with great misgivings, because it made a mistake. Did it or did you? Well ultimately you did, but you have to blame something. So the calculator takes the heat.

Who  knows? Maybe the decimal doesn't work. It's stuck or something. In any event you should be aware that there's no way the answer could be 0.36 when you estimate it to be 3.

This is a proportion. What is the value of X?
Verizon [17]

Answer:

x = 15 or x = - \frac{2}{5}

Step-by-step explanation:

Cross- multiplying gives

(14x + 6)(17x + 5) = 9x(27x + 11) ( expanding factors )

238x² + 172x + 30 = 243x² + 99x

rearrange into standard form : ax² + bx + c = 0

5x² - 73x - 30 = 0 ← in standard form

consider the factors of the product 5 × - 30 = - 150 which sum to the coefficient of the x-term (- 73 )

the factors are - 75 and + 2

Use these factors to split the middle term

5x² - 75x + 2x - 30 = 0 ( factor by grouping )

5x(x - 15) + 2(x - 15) = 0 ← take out the factor (x - 15)

(x - 15)(5x + 2) = 0

equate each factor to zero and solve for x

x - 15 = 0 ⇒ x = 15

5x + 2 = 0 ⇒ x = - \frac{2}{5}

Valerie is ordering salads and drinks for her friends. salads cost $7 each, drinks cost $3 each, and there is a $5 delivery char
Helen [10]

Since there is a $5 delivery charge, Valerie will surely spend those money.

Also, since a salad costs $7, and Valerie buys 3 of them, she will spend 21 more dollars.

So, salads and delivery charge sum up to 21+5 = 26

This means that Valerie has 50-26 = 24 dollars left. A drink costs $3, so she can buy

\dfrac{24}{3} = 7 drinks.
