Mark got 54 out of 66 correct in his test. What fraction of the marks did he get correct? Give your answer in its simplest form

elixir [45]

Answer:

$\texttt{Fraction of the marks did he get correct}=\frac{9}{11}$

Step-by-step explanation:

Mark got 54 out of 66 correct in his test.

We need to find what fraction of the marks did he get correct,

Total number of questions = 66

Total number of correct answers = 54

$\texttt{Fraction of the marks did he get correct}=\frac{\texttt{Total number of correct answers}}{\texttt{Total number of questions}}\\\\\texttt{Fraction of the marks did he get correct}=\frac{54}{66}\\\\\texttt{Fraction of the marks did he get correct}=\frac{9}{11}$

(3-4i)(-2-21) multiply

evablogger [386]

Answer:

-69 +92 i (here 'i' is imaginary value)

Step-by-step explanation:

step:-

Given (3-4 i)(-2-21)

on multiplication, we get

(3-4 i)(-2-21) = 3(-2) -3(21) - 4 i (-2) +4 i(21)

= -6 -63 + 8 i +84 i

= -69 +92 i

-69 + 92 i is a complex number.

real part x = -69

imaginary part y = 92

Which of the following statements are true about the given rational equation? check all of the boxes that apply. 4 x 6 1 x2 = x

Agata [3.3K]

We can actually see that the statements that are true are:

A. x = 1 is a solution.

C. x = –1 is a solution.

<h3>What is rational equation?</h3>

Rational equation is actually known as an equation that contains at least one fraction. The denominator and numerator are known to be polynomials.

We can see then that:

$\frac{4}{x + 6} + \frac{1}{ {x}^{2} } = \frac{x + 10}{ {x}^{3} + 6 {x}^{2} }$
