The percentage of increase in Roberto score is 14.87%, if Roberto made a 74 on last weeks math quiz. this week he made an 85 on the quiz.

Step-by-step explanation:

The given is,

               Roberto score on math quiz at last week is 74

               This week he made an 85 on the quiz

Step:1

            Formula to calculate the percentage of increase the score,

                  Percentage of increase = \frac{Final score-Starting score}{Starting score} × 100...........(1)

            From the given,

                  Final score = 85

                  Starting score = 74

           Equation (1) becomes,

                  Percentage of increase =( \frac{85-74}{74}) ×  100

                                                       = (\frac{11}{74}) ×  100

                                                       = 0.1486486  ×  100

                                                       = 14.86486 %

                                                      ≅ 14.87 %

              Percentage of increase = 14.87 %

Result:

        The percentage of increase in Roberto score is 14.87%, if Roberto made a 74 on last weeks math quiz. this week he made an 85 on the quiz.

Answer:

? = 13.6

Step-by-step explanation:

the angle between a tangent and the diameter = 90°

Then the triangle is right with legs 2 × 6 = 12 and 6.4

using Pythagoras' identity in the right triangle.

the square on the hypotenuse is equal to the sum of the squares on the legs , that is

? ² = 12² + 6.4² = 144 + 40.96 = 184.96 ( take square root of both sides )

? = \sqrt{184.96} = 13.6
