Step-by-step explanation:

Area of a triangle is given by

A =  \frac{1}{2}  \times base \times height \\

From the question

base = 18

height = 6

So we have

A =  \frac{1}{2}  \times 18 \times 6 \\  = 9 \times 6 \\  = 54 \:  \:  \:  \:  \:

We have the final answer as

Nolini says that if the denominator is more than twice the numerator, the fraction can always be replaced with a 0. Is she corre
Len [333]

Answer:

yes

Step-by-step explanation:

It depends on how accurate you want your answer to be, but basically yes, imagine we set our numerator to be x, and our denominator to be 2x, if we built our fraction we will get that:

\frac{x}{2x}=\frac{1}{2}

If the denominator of a fraction is exactly twice the numerator, then the fraction will be simplified to 1/2 or 0.5.

Now, the greater the denominator is, the closer the fraction will get to zero.

Take for example I had an fraction like this:

\frac{3}{6}=0.5

which approximates to 0. If we made the denominator bigger, let's say 7, we would get:

\frac{3}{7}=0.43

notice the answer is closer to 0 this time, so it's valid to round it to zero. If we made the denominator greater, let's say 25, we would get:

\frac{3}{25}=0.12

and so on. So it is true that if the denominator of a fraction is greater than twice the numerator, we can always replace the fraction with a 0 (depending on how accurate you want your answer to be).
