Simplify the expression. 12x^-6 y^10 times 3x^7 y
Vlada [557]

We need to simplify the expression:

12x^{-6}y^{10} \times (3x^{7}y)

Now, we know that we can resolve the exponents of the variables with the like terms only and we can multiply the coefficients independently:

Now,  

12x^{-6}y^{10} \times 3x^{7}y=(12 \times 3)\times (x^{-6}\times x^{7})\times (y^{10}\times y)

On simplifying the above expression we get:

36\times x^{(-6+7)}\times y^{(10+1)}

=36 \times x^{1}\times y^{11}

=36 \times x \times y^{11}

=36xy^{11}

So the simplified form of the expression 12x^{-6}y^{10} \times 3x^{7}y=36xy^{11}.

PLS help meeeeeeee!!!!!! will mark as BRAINLIEST
Zolol [24]

We are asked to find 7 is what percent to 30.

We will use proportions to solve our given problem.      

Let us assume that 7 is n% of 30. So we can set a proportion as:

\frac{n}{100}=\frac{7}{30}

Let us solve for n.

\frac{n}{100}\cdot 100=\frac{7}{30}\cdot 100

n=\frac{7}{3}\cdot 10

n=\frac{70}{3}

n=23.333

Therefore, 7 is 23.333\% of 30.
