12 one half times one nine

pshichka [43]

Answer:

$1\frac{7}{18}$ or one seven eighteenths

Step-by-step explanation:

we know that

12 one half times one nine is the same that multiply 12 one half by one nine

$(12\frac{1}{2})(\frac{1}{9})$

Convert mixed number to an improper fraction

$12\frac{1}{2}=12+\frac{1}{2}=\frac{12*2+1}{2}=\frac{25}{2}$

substitute

$(\frac{25}{2})(\frac{1}{9})=\frac{25}{18}$

Convert to mixed number

$\frac{25}{18}=\frac{18}{18}+\frac{7}{18}=1\frac{7}{18}$

therefore

12 one half times one nine is one seven eighteenths

shepuryov [24]

Answer:

$\frac{2}{5}$

Step-by-step explanation:

The total length of this line is 15 units. FG is 6 units long.

This means that the probability of p being on FG would be $\frac{6}{15}$ which can be simplified to $\frac{2}{5}$

A binomial squared is written like

$x^2+2ax+a^2$

So, we have $2a=6 \iff a=3$

So, we want to complete the square $(x+3)^2 = x^2+6x+9$

We can add and subtract 9 to write

$x^2+6x = x^2+6x+(9-9) = (x^2+6x+9)-9 = (x+3)^2-9$
