Evaluate 38+16 * 12÷2-(30 * 2)
Dvinal [7]

Answer

The answer is 8040

Step-by-step explanation:

It might be wrong, but here take it this way with Pemdas.

P= Parenthesis (30*2) and what's in there is multiplication correct? So, 30 times 2 is 60. Then, E is exponents. There's none there. So we skip to multiplication. 16 times 12 is what? 192. Next is division. So 192 divided by 2. That's 96. So, Then it'd be 38+96(60.) 38+96= 134. 134(60) That being said. That would equal  = 8040  using Multiplication, 194 using addition. 74 using subtraction. And 2.2_ using division.

What percent of 1600 is 2?
Misha Larkins [42]

Answer: 0.125%

Step-by-step explanation:

Let 1600 corresponds to the 100% value and 2 is a part of the total 100% value 1600.

The formula to find the percent of a part :_

\%=\dfrac{\text{Part}}{\text{Total}}\times100

Substitute Part= 2 and Total = 1600 in the formula, we get :-

\%=\dfrac{2}{1600}\times100\\\\\Rightarrow\ \%=\dfrac{1}{8}\%=0.125\%

Therefore, 2 is 0.125% of 1600.

Hence, the percent of 1600 is 2 = 0.125%
