On the first of three tests Kayla scored 72points. On the third test her score was 1 point more than on the second. Her average
Kitty [74]

Answer:

The answer to your question is:

first test = 72

second test = 88

third test = 89

Step-by-step explanation:

Data

First test = 72 points

Second test = x

Third test = x + 1

Average of the three test = 83

Process

       (First test  + Second test  + Third test) / 3  = 83

       ( 72 + x + x +1 ) / 3 = 83

        73 + 2x = 3(83)

        73 + 2x = 249

        2x = 249 - 73

        2x = 176

        x = 176 / 2 = 88   second test

        third test = x + 1 = 88 + 1  = 89

Find the area and perimeter of the shape below
Sladkaya [172]

Solution:

<u>Note that:</u>

  • Area = Base x Height
  • Perimeter = Sum of all sides

<u>Finding the area of the parallelogram:</u>

  • Area = Base x Height
  • => Area = 9.2 x 3.8
  • => Area = 34.96 cm²

<u>Finding the perimeter of the parallelogram:</u>

  • Perimeter = Sum of all sides
  • => Perimeter = 2(4.1) + 2(9.2)
  • => Perimeter = 26.6 cm

Correct option is D.
