Answer:

The remnant of an estate that the grantor holds after he's granted a life estate to another person if the estate will return to the grantor, is called D) Reversion

Question~

Rasek [7]

Answer:

B. 1

Step-by-step explanation:

Multiply the first term by $x^a$ , the second term by $x^b$ , the third term by $x^c$ .

The first term becomes:

$x^a/(x^a+x^b+x^c)$

The second term becomes:

$x^b/(x^a+x^b+x^c)$

The third term becomes:

$x^c/(x^a+x^b+x^c)$

Their sum is:

$(x^a+x^b+x^c)/(x^a+x^b+x^c) = 1$

Correct choice is B

An aquarium tank holds 475 liters of water. How much is this in gallons? Use the following conversion: 1 gallon is 3.8 liters.

Mrrafil [7]

$\bf \begin{array}{ccll}
liters&gallons\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
3.8&1\\
475&g
\end{array}\implies \cfrac{3.8}{475}=\cfrac{1}{g}\implies g=\cfrac{475\cdot 1}{3.8}$
