You have an office building that is 600 square feet in area. What are two possible dimensions how your office could be construct

stepan [7]

Answer:

$20\ ft$ by $30\ ft$

$15\ ft$ by $40\ ft$

Step-by-step explanation:

In this problem I'm assuming the office is rectangular.

The area of rectangle is equal to

$A=LW$

where

L is the length of the rectangle

W is the width of the rectangle

In this problem we have

$A=600\ ft^{2}$

$600=LW$ ------> equation A

Find two possible dimensions of the office

case A) Assume a length side L and find the value of W in the equation A

For $L=30\ ft$

substitute in the equation and solve for W

$600=(30)W$

$W=600/30=20\ ft$

The dimensions are $20\ ft$ by $30\ ft$

case B) Assume a length side L and find the value of W in the equation A

For $L=40\ ft$

substitute in the equation and solve for W

$600=(40)W$

$W=600/40=15\ ft$

The dimensions are $15\ ft$ by $40\ ft$

Which expressions are equivalent to the one below? Check all that apply.<br> log 2 - log 8

blagie [28]

Answer:

$\log 2-\log 8=\log\frac{1}{4}\\\\\log 2-\log 8=-\log 4$

Step-by-step explanation:

$\log 2-\log 8=\log\frac{2}{8}\ \ \ \ \ \ \ \ \ \ \ \ \ \ \log\frac{a}{b}=\log a-\log b\\\\\log 2-\log 8=\log\frac{1}{4}\\\\\log 2-\log 8=\log 1-\log 4\ \ \ \ \ \ \ \ \ \ \ \ \ \ \log\frac{a}{b}=\log a-\log b\\\\\log 2-\log 8=-\log 4\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \log 1=0$
