As a water quality assurance employee for your local Aqua America, Inc., branch, you record a drop in water levels from 28 feet
ioda
So, it went down from 28 to 7, meaning 28 - 7 = 21, 21 feet then.

now, if we take 28 to be the 100%, what is 21 off of it in percentage?

\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
28&100\\
21&p
\end{array}\implies \cfrac{28}{21}=\cfrac{100}{p}\implies p=\cfrac{21\cdot 100}{28}

saveliy_v [14]

Answer:

n = 8

Step-by-step explanation:

Follow the question when turning the word equation into an equation

Because we know this is a quadratic equation, the product is a result of n multiplied by itself

n^{2} -4=60

Solve for n

n^{2} =64

\sqrt{n^{2} } =\sqrt{64}

n = 8

Arrange the following polynomial into descending order for x, then interpret the degree of the 2nd term. 7x3y3 + 4 − 11x5y2 − 3x
miss Akunina [59]

Answer:

6

Step-by-step explanation:

7x^3y^3 + 4 - 11x^5y^2 - 3x^2y =

The exponents of x (in the order the polynomial was given) are: 3, 0, 5, 2

Now we put the exponents of x in descending order.

= -11x^5y^2 + 7x^3y^3 - 3x^2y + 4

The second term is 7x^3y^3

The degree of a term is the sum of the exponents of all variables of the term. The exponent of x is 3. The exponent of y is 3, and 3 + 3 = 6.

The degree of the second term is 6.

Answer: 6
