In a cave, a stalactite gets 44 millimeters longer each year. this year it is 72 centimeters long. how many years until it is 1

iragen [17]

Answer:

6.36 years (the .36 repeats), so rounded is 6.4.

Step-by-step explanation:

First, I'm going to convert all measurements to meters.

Since 1000 mm = 1 m, divide 44 by 1000.

44/1000 = 0.044 m

Since 100 cm = 1 m, divide 72 by 100.

72/100 = 0.72 m

Next, I'm going to setup an equation using y = mx + b.

b is the beginning amount which is 0.72.

m in the equation represents the rate which is 0.044.

y represents the total which is 1.

Plugin the numbers and solve for x.

1 = 0.044x + 0.72

1 - 0.72 = 0.044x + 0.72 - 0.72

0.28 = 0.044x

0.28/0.044 = 0.044x/0.044

6.36 = x

Simplify the rational expressions. State any excluded values. X^2-4/2-x

tatiyna

Answer:

-x-2; x $\neq$ 2

Step-by-step explanation:

$\frac{x^2-4}{2-x}$ -->

$\frac{(x-2)(x+2)}{(2-x)}$ -->

-(x+2); x CAN'T equal 2, because the denominator of the original fraction would be 0, which would make the term undefined.

frozen [14]

The equation is

A is the first number, ratio, rate, etc. , and B is the second.
The ≠ symbol means "does not equal", so the equation means:
[ Ratio A is NOT equal to Ratio B. ]
