Sophia scored 92% in a math test. if the test had 50 question how many did she get right

german

Answer: 46

Step-by-step explanation:

percentage scored = 92

number of correct question = x

total number of questions = 50

The formula for calculating the percentage scored

= number of correct question / total number of questions x 100

That is

92 = $\frac{x}{50}$ x $\frac{100}{1}$

$92 = \frac{100x}{50}$

cross multiplying :

$100x = 92$ x $50$

$100x = 4600$

dividing through by 100 , we have

$x = 46$

Therefore, she got 46 questions right

Answer:

AOB = 40 degrees

Step-by-step explanation:

The two smaller angles, AOB and BOC, add up to form AOC. That means that the angles of AOB and BOC sum up to the angle of AOC

$3x+4+8x-28=108\\11x=132\\x = 12\\\\3(12)+4=AOB\\AOB = 40 degrees$
