a student has answered 82% of the questions correctly in the examination. He made mistakes in 9 questions Calculate the toltal n
Sonja [21]

Answer:

There is a total 50 questions.

Step-by-step explanation:

Let x = total questions in the exam

Since 82% of the test was scored correctly, that means 18% of the student's exam was scored incorrectly.

With this information we can write:

18\%x=9 (Given that the student made 9 mistakes)

x=9\div18\% (divide 18% on both sides)

x=50

∴ There was a total of 50 questions in the examination.

Geometry Question Help if you can please
docker41 [41]

Answer:

≈ 78.55 cm

Step-by-step explanation:

Using the ratio of arc (AB) to circumference (C) is equal to the ratio of angle subtended at centre by arc AB to 360°, that is

\frac{AB}{C} = \frac{110}{360} , that is

\frac{24}{C} = \frac{110}{360} ( cross- multiply )

110C = 8640 ( divide both sides by 110 )

C = \frac{8640}{110} ≈ 78.55 cm ( to 2 dec. places )
