If a lot contains 48,000 square feet and is 240' wide, how deep is the lot?
lisabon 2012 [21]
We would assume the lot takes a rectangular shape. With that in mind. the area of the rectangular plot is 48, 000 and its width is 240. We only need to know the area of a rectangle which is L * W.  
So 48, 000 = L * 240 
L = 48, 000/ 240  
L = 200 
It is 200 square feet deep.

2.1x10^6<br> ______<br> 7x10^3<br><br> answer in standard form<br> ...................10^......
VMariaS [17]

Given:

The expression is:

\dfrac{2.1\times 10^6}{7\times 10^3}

To find:

The simplified form of the given expression in standard form.

Solution:

We have,

\dfrac{2.1\times 10^6}{7\times 10^3}

It can be written as:

\dfrac{2.1\times 10^6}{7\times 10^3}=\dfrac{21\times 10^5}{7\times 10^3}

\dfrac{2.1\times 10^6}{7\times 10^3}=\dfrac{21}{7}\times \dfrac{10^5}{10^3}

\dfrac{2.1\times 10^6}{7\times 10^3}=3\times 10^{5-3}        [\because \dfrac{a^m}{a^n}=a^{m-n}]

\dfrac{2.1\times 10^6}{7\times 10^3}=3\times 10^2

Therefore, the required value is 3\times 10^2.
