Answer:

  • D. 45/18 = 35/14

Step-by-step explanation:

<u>Lets simplify the ratios where possible and compare:</u>

  • A. 3/4 = 9/12 ≠ 5/12
  • B. 32/20 = 16/10 ≠ 22/10
  • C. 7/5 = 14/10 ≠ 14/9
  • D. 45/18  = 5/2 (divide by 9) and 35/14 = 5/2 (divide by 7)

The last two ratios represent proportional quantities

Suppose you choose a marble from a bag containing 6 red marbles , 2 white marbles and 5 blue marbles you return the first marble
algol [13]

Answer:

30/169

Step-by-step explanation:

We need to know how many marbles in the bag

6 red marbles + 2 white marbles + 5 blue marbles = 13 marbles

P (red) = red / total = 6/13

We then put the marble bad so there are still 13 marbles in the bag

P(blue) = blue /total = 5/13

P (red then blue ) = P(red) *P(blue)

                             = 6/13 * 5/13 = 30/169

Length of Base 1 - 1 unit,\\\\Length of Base 2 - 4 units,\\\\Length of Height - 3 units ( length of x - intercept in shaded region )\\\\Area of Trapezoid = ( Average of Bases ) * Height = ( ( 1 + 4 ) / 2 ) * 3 = ( 5 / 2 ) * 3 = 7.5 square units,\\\\Solution; 7.5 square units

<em>Area = 7.5 square units</em>
