So 20% didn't enjoy going to the movies.
If 5,200 = 100% then 1040 = 20%.

1,040 teenagers do not enjoy going to the movies out of 5,200. 80% of 5,200 is 4,160. You would have to subtract 4,160 from 5,200 which is 1,040.

You are attempting to estimate the number of protester marching through the city
Alenkinab [10]

9514 1404 393

Answer:

  1000

Step-by-step explanation:

If the number of protesters per minute remains a constant, then you could write the proportion ...

  p/12 = 177/2.1

Multiplying by 12 gives ...

  p = 12(177/2.1) ≈ 1011.4

Here, minutes are given to 2 significant figures, and the initial count is given to 3 significant figures. The best you can hope for is that your estimate is good to 3 significant figures:

 1010 protesters

It is probably sufficient to report the number to 2 significant figures*:

  1000 protesters

_____

* Unfortunately, with a number like 1000, the only way you can tell it has 2 significant figures is to report it as 1.0×10³ or 10. hundreds. The trailing zeros are usually not considered significant.

Rationalize the denominator of square root of negative 49 over open parentheses 7 minus 2 i close parentheses minus open parenth
navik [9.2K]

The answer is the option d, which is: d) \frac{-77+21i}{130}

The explanation for this problem is shown below:

1. Smplify the denominator and rewrite the numerator in this form:

\frac{7i}{7-2i-4-9i} \\\frac{7i}{3-11i}

2. Multiply the denominator and the numerator by the conjugated (3+11i) and simplify the expression, as following:

\frac{7i(3+11i)}{(3-11i)(3+11i)} \\ \frac{21i+77i^{2}}{121+9}  \\ \frac{-77+21i}{130}

3. As you can see, you obtain the expression shown in the option mentioned above.
