Answer:

  5/9

Step-by-step explanation:

The area of one triangle is ...

  A = 1/2(x)(2x) = x²

Then the area of the four triangles is ...

  unshaded area = 4(x²)

The length of DC is 2x+x = 3x, so the area of ABCD is ...

  total area = (3x)² = 9x²

Then the fraction that is shaded is ...

  (9x² -4x²)/(9x²) = 5/9

5/9 of the area of ABCD is shaded.

Mateo has been studying after school while preparing for a test retake. His work paid off ! His score on the retake was a 94. Th
Feliz [49]

Answer:

28%

Step-by-step explanation:

We know that 100 percent is total. Mateo first scored 68/100, then a retake got his score up to 94/100.

First, subtract the two numbers

94 - 68 = 26

Put 26 over 94 to make this 26/94

Divide to get 0.28 (simplified and rounded)

So the increase was 28%
