A real estate purveyor purchases a 60,000square foot warehouse and decides to turn it into a storage facility. The warehouse's w
Bess [88]

Answer:

Therefore the width of the warehouse is 245 feet.

Step-by-step explanation:

Rounding to the nearest foot:

  • If the digit of tenths place is between 1-4, then the unit digit remains same.
  • If the digit of tenths place is between 5-9, then the unit digit increases by 1.

Given that,

A real estate purchases a 60,000 square foot warehouse.

The width of  warehouse is exactly of its length.

Since the unit of  60,000 is square foot. So, it is area of the warehouse.

The area of a rectangular plot is = Length× width.

Since the width of  warehouse is exactly of its length.

Then the length of the ware house = the width of the warehouse

∴ Length× width =60,000

⇒width× width =60,000

⇒ width² =60,000

\Rightarrow width=\sqrt{60,000}

\Rightarrow width\approx 244.94

⇒ width =245 feet.( nearest to feet)

Therefore the width of the warehouse is 245 feet.

Find the cost of something after a discount
11111nata11111 [884]
Take the discount. Let's call it x%. Turn it into a fraction, and multiply it by the item. Let's call the item "i". 
The amount discounted is \frac{ix}{100}.
Now subtract this from the original cost of the item. 

Therefore, i - \frac{ix}{100} is the solution.

What times what equals 12 but when you add those numbers together it equals positive 2
Tresset [83]

Hello from MrBillDoesMath!

Answer:

1 - i sqrt(11) , 1 + i sqrt(11)  

Discussion:

Translating the Question into mathematical symbols:

x * y = 12     (*)

x + y = 2      (**)

From (**),  y  = 2 - x. Substitute this value in (*)

x * y = x * (2-x) = 12     =>

2x - x^2 = 12               => add x^2, subtract 2x from both sides

0 =  x^2  -2x + 12    

Solving using the quadratic formula gives

x = 1 - i sqrt(11)

and

y = 1 + i sqrt(11)

Thank you,

MrB
