The perimeter of a pool table is 30 feet. The table is twice as long as it is wide. What is the length of the pool table?
olga55 [171]

So, 30 is the perimeter. We are told the table is twice as long as it is wide.

So, we have think of 2 numbers, one being twice as big than the other. So, it is a rectangle The two number represents the length and the width. To find the perimeter we add all the lengths and the widths. Since the pool table is a rectangle we have two lengths and two widths.

So,

the tow numbers be 10 and 5. 5 is half of 10 and, when multiplied by 2 it is 10. So just to make sure the numbers 5 and 10 work out lets do a calculation.

So,

10+5+10+5 = 30feet. This proves that the sides are these two numbers.

This circle is centered at the origin, and the length of its radius is 8. What is
Kitty [74]

\quad \huge \quad \quad \boxed{ \tt \:Answer }

\qquad \tt \rightarrow \: x² + y² = 64

____________________________________

\large \tt Solution  \: :

Standard equation of circle is :

\qquad \tt \rightarrow \: (x - h) {}^{2}  + (y - k) {}^{2}  =  {r}^{2}

  • \textsf{h = x - coordinate of centre of circle}

  • \textsf{k = y - coordinate of centre of circle}

  • \textsf{r = radius= 8}

Since the circle is centered at origin, h = k = 0

\qquad \tt \rightarrow \: (x - 0) {}^{2}  + (y - 0) {}^{2}  =  {8}^{2}

\qquad \tt \rightarrow \:  {x}^{2}  +  {y}^{2} = 64

Find the sales tax. Then find the total cost of the item.
dezoksy [38]

Answer:

Step-by-step explanation:

You must state the "price before tax".  Let this be P.  Also, you must state the sales tax rate.  Let this be r, where r is a decimal fraction.  

Then the sales tax is rP, the product of the tax rate and the "price before tax."

The total cost of the item (for which it is sold) is (P + rP)($40).

If P = $40 and the sales tax rate is 7%, then

this total cost is (1 + 0.07)P = 1.07P = $42.80

Your question would be clearer if you wrote it like this:  Given that the base price of an item is $40 and that the sales tax rate is 7%, find the total cost of the item with tax.  That would be (1 + 0.07)($40), or $42.80.

The sales tax is $42.80 - $40 = $2.80.
