the whole exam will be 100%, and let's say that's "x" questions, but we also know that 9 is 60% of that so

\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} x&100\\ 9&60 \end{array}\implies \cfrac{x}{9}=\cfrac{100}{60}\implies \cfrac{x}{9}=\cfrac{5}{3}\implies 3x=45 \\\\\\ x=\cfrac{45}{3}\implies x=15

What is the answer to <br> 5 (x - 1) + 3 = 13
AleksAgata [21]

Step-by-step explanation:  To solve for x when the equation includes an exponent, start by isolating the term with the exponent. Then, isolate the variable with the exponent by dividing both sides by the coefficient of the x term to get your answer. If the equation has fractions, start by cross-multiplying the fractions.

Indicate which formula you would use to solve for the missing side B and then write your answer correct to two decimal places.Wr
agasfer [191]

Answer:

The measure of the angle b is approximately 44.040°.

Step-by-step explanation:

We need to apply Law of the Sine to determine the value of angle b, since the length of the side opposite to this side and another side length and its opposite angle are known. That is:

\frac{3.6}{\sin b} = \frac{5.1}{\sin 100^{\circ}}

\sin b = \frac{3.6}{5.1}\times \sin 100^{\circ}

b = \sin^{-1}\left(\frac{3.6}{5.1}\times \sin 100^{\circ} \right)

b \approx 44.040^{\circ}

The measure of the angle b is approximately 44.040°.
