Consider the equation of a circle given by (x+8)² + (y+4)² = 256. What is the diameter of the circle?

The diameter of the circle with the circle equation (x+8)² + (y+4)² = 256 is 32 units

<h3>How to determine the diameter?</h3>

The equation of the circle is given as:

(x+8)² + (y+4)² = 256

As a general rule, a circle equation is represented as:

(x - a)² + (y - b)² = r²

Where r is the radius.

By comparing both equations, we have:

r² = 256

Take the square roots of both sides

r = 16

Multiply by 2 to get the diameter

d = 32

Hence, the diameter of the circle is 32 units

How may weeks are there in a year?​
Zanzabum

Answer:

There are exactly 52.142857142857 weeks in the year 2019. This is equivalent to 52 weeks and 1 extra day, since there are 365 total days in 2019. Most years have 365 days, but a leap year has 366 days. That adds up to 52 weeks (where each week is exactly 7 days) PLUS 1 or 2 additional days.There are 52 complete weeks in a year. The year has 365 days, leaving one extra day. A leap year has 366 days, adding a second extra day. This makes 52 1/7 weeks in a normal year and 52 2/7 weeks in a leap year..

topjm [15]
Steve picked 55 pounds of pears. He had 4 left after dividing them into 6 bags, so he packed 55 - 4 or 51 pounds of pears into the bags.

If there is an equal weight in each bag, then we can find the answer by dividing 51/6 which gives us 8.5 pounds of pears per bag.

\frac{n}{5} =  \frac{72}{8} \\ \\  \frac{n}{5} = 9 \\ \\ n = 9 \times 5 \\ \\ n = 45 \\ \\

The final result is: n = 45.

---------

\frac{9}{n} =  \frac{4}{18} \\ \\  \frac{9}{n} =  \frac{2}{9} \\ \\ 9 =  \frac{2}{9} n \\ \\ 9 =  \frac{2n}{9} \\ \\ 9 \times 9 = 2n \\ \\ 81 = 2n \\ \\  \frac{81}{2} = n \\ \\ n =  \frac{81}{2} \\ \\

The final result is: n = 81/2 or n = 40.5.
