Answer:
The density of oak is <u>0.695</u> grams per cubic centimeter.
Step-by-step explanation:
Given:
Oakwood has a mass of 2.85 kilograms and a volume of 4100 cubic centimeters.
Now, to find the density of oak in grams per cubic centimeter.
Mass (m) = 2.85 kilograms.
So, using conversion factor we convert into grams:
Volume (v) = 4100 cubic centimeters.
Now, to get the density by using formula:
Therefore, the density of oak is 0.695 in grams per cubic centimeter.
All you do is divide by three to get 9.667 which is 9 and 1/3 feet
#25 is fairly simple. Plug in -4 and 3 into the equation, and the extraneous root will be the one that does not work.
Extraneous root in this case is positive four since +4≠-4

</span>In this case it's negative 3, since -3≠3
#29 can be turned into a quadratic equation.
Square both sides to get
Then bring the 2x+3 to the other side, setting the quadratic equal to zero.
Factor to find that it's equivalent to
(x-3)(x+1)=0
Therefore x is equal to positive 3 and negative 1. Plug both back into the original equation. Whichever does not work is the extraneous root, and the answer is the one that does.

Your answers are positive 3 and negative 1.
Extraneous roots are negative 3 and positive 1.
You do 49.50 times 4% equals $1.98. You than add $49.50 plus $1.98 that equals to $51.48 the total you paid for the shoes
