1. Rational. It is non-terminating but repeating.
2. Irrational. It is non-terminating, non-repeating
3. Irrational. π is irrational
4. Rational. √49 is 7
5. Irrational. 22 is not a square.
Answer:
$104.70
Step-by-step explanation:
The equation would be set up like this: 80.45 + 20.50(3) - 37.25. You started off with $80.45 in your bank account and deposited, or added, $20.50 every day on Tuesday, Wednesday and Thursday. That would mean you added $20.50 three times. Adding $80.45 + $20.50 + $20.50 + $20.50, simplified to $80.45 + $20.50(3) would get you $141.95 in total. Then, on Friday, you withdraw $37.25, getting the equation $141.95 - $37.25, leaving $104.70 for the weekend.
<span>You have studied polynomials consisting of constants and/or variables combined by addition or subtraction. The variables may include exponents. The examples so far have been limited to expressions such as 5x<span>4 </span>+ 3x<span>3 </span>– 6x<span>2 </span>+ 2x containing one variable<span>, </span>but polynomials can also contain multiple variables. An example of a polynomial with two variables is 4x2y – 2xy2 + x – 7.</span>
Many formulas are polynomials <span>with more than one variable, such as the formula for the surface area of a rectangular prism: 2<span>ab </span>+ 2bc + 2ac, where <span>a, b, </span>and <span>c </span>are the lengths of the three sides. By substituting in the values of the lengths, you can determine the value of the surface area. </span>By applying the same principles for polynomials with one variable, you can evaluate or combine like terms in polynomials with more than one variable<span>.</span>
Answer
1.) B
2.) 3 hours
Step-by-step explanation:
1.) option B is correct I think because it shows he will either be equal to or less than how much money he wants to spend
2.) i got three because if you sent up the equal I picked in question one then you subtract 28 from 250 giving u 222 and you divide that by 65 giving you 3.4 but he only charges by the whole hour so that .4 of an hour he wouldn't charge you for
