How much money do I need to make to still have 1,000,000 left after 27.4% tax is removed?
Rama09 [41]

let's say the amount is "x", hmmm how much is 27.4% of "x"?   well

\bf \begin{array}{|c|ll} \cline{1-1} \textit{a\% of b}\\ \cline{1-1} \\ \left( \cfrac{a}{100} \right)\cdot b \\\\ \cline{1-1} \end{array}~\hspace{5em}\stackrel{\textit{27.4\% of x}}{\left( \cfrac{27.4}{100} \right)x}\implies 0.274x

so then, we know that x - 0.274x = 1000

\bf x - \stackrel{\textit{27.4\% of "x"}}{0.274x}=1000\implies 0.726x=1000\\\\\\ x = \cfrac{1000}{0.726}\implies x\approx 1377.41

Find the GCF of the following monomials.<br><br> -50m4n7 and 40m2n10
Dima020 [189]

Answer:

Assuming you are asking for the Greatest Common Factor (GCF) of -50m^4n^7 and 40m^2n^{10} the answer is:

10m^2n^7

Step-by-step explanation:

To find the GCF we should first find the GCF of the coefficients 50 and 40 which is 10.

After factoring that out we need to take a look at the variable m. In monomial 1 we see that the highest exponent of m is 4 and in the second is 2. When finding GCF we take the smallest of the two exponents which is 2. Therefore the next part of our GCF monomial is m²

If we apply the same rule for n the smallest exponent is 7 resulting in the appending of n^{7} to the answer

After combining each of these GCF of 40 and -50 (10), m^4 and m² (m²), and n^7 and n^10 (n^7) the answer is:

10m^2n^7

?<br> 6.2<br> Divided by 1/2
ratelena [41]

Answer:

The answer is 3.1

6.2 \div \frac{1}{2} = 3.1

If we were to convert it into a **FRACTION** the answer would be : 31/10.

And that i an improper fraction, but as a **MIXED NUMBER** : 3 \frac{1}{10}

All answers would be : 3.1 , 31/10 and 3 1/10
