When buddy discovers the revolving door, he goes 4 complete revolutions in 11 seconds. How many times around would he go if he c
mezya [45]
To figure out how many revolutions Buddy goes in 1 minute, (60 seconds) we can use proportions

4 revolutions/11 seconds = x revolutions/60 seconds
When we cross multiply, (multiplying one numerator by the other denominator, and vice versa for the other numerator) we get
240 = 11x
divide both sides by 11 to get
21.81 = x
or 21 complete revolutions

Arrange the following polynomial into descending order for x, then interpret the degree of the 2nd term.
8_murik_8 [283]

The <em><u>correct answer</u></em> is:

The order is -11x⁵y² + 7x³y³ - 3x²y + 4; and the degree is 6.

Explanation:

To order them by x, we look at the powers of x.  In the original polynomial, the power of x in the first term is 3, the power of x in the second term is 0, the power of x in the third term is 5, and the power of x in the last term is 2.  Arranging them, we want 5, 3, 2 and 0.  This explains the order.

The second term of the ordered polynomial is 7x³y³.  The degree is found by adding the exponents of the variables in the problem; this gives us 3+3 = 6.
