Musya8 [376]3 years ago
7 0

Answer:

The diameter of the circle would be: 6.4 cm. rounded or 6.36619772 cm.

The radius of the circle would be: 3.2 cm. rounded or 3.18309886 cm.

Step-by-step explanation:

<h3>The diameter can be solved using: D = \frac{C}{\pi }</h3>

So, the first step would be : D = \frac{20}{\pi }

Then : D = 20 ÷ \pi

Finally, the answer will be : 6.36619772 cm. or 6.4 cm.

<h3>The Radius can be Solved using: r = \frac{c}{2\pi }</h3>

The first step would be : r = \frac{20}{2\pi }

Then : 20 ÷ 6.2831853071796 (2\pi)

Finally, the answer will be : 3.18309886 cm. or 3.2 cm.

Find each quotient. Write in simplest form. keep answer as fraction - not decimal
kirill [66]

So we are given the expression:

\frac{mn^{2}}{4} ÷ \frac{m^{2}n}{8}

When we divide fractions, we must flip the second term and change the sign to multiplication:

\frac{mn^{2}}{4} *\frac{8}{m^{2}n}

And then we multiply across:

\frac{mn^{2}}{4} *\frac{8}{m^{2}n}= \frac{8mn^{2}}{4m^{2}n}

Then we can break apart all of the like variables for simplification:

\frac{8mn^{2}}{4m^{2}n}=\frac{8}{4} * \frac{m}{m^{2}} *\frac{n^{2}}{n}

When we simplify variables through division, we subtract the exponent of the numerator from the exponent of the denominator. So we then have:

\frac{8}{4} =2

\frac{m}{m^{2}}=m^{-1} =\frac{1}{m}

\frac{n^{2}}{n}=n^{1}=\frac{n}{1}

So then we multiply all of these simplified parts together:

\frac{2}{1}*\frac{1}{m}*\frac{n}{1}   =\frac{2n}{m}

So now we know that the simplified form of the initial expression is: \frac{2n}{m}.

I need help and I will give brainliest to the person with the right answers and explanation
densk [106]

Answer:     Part A: y= -1200x +25000 this is because it decreases 1200$ a year that is your rate of change and it started at 25000 that is your y-intercept

                  Part B:  question a would be 46000$ because that’s where the zero is which is when he bought it question b is 3000$ because that is how much the table decreases with each year
