The figure represents the shape of a kitchen floor. What is the area? (round to the nearest hundredth)
Murljashka [212]
We would divide the shape into a rectangle and a trapezium

The rectangle is of length, 24.5 ft and width 10.75 ft

Area =  24.5 * 10.75 = 263.375 square feet.


Trapezium :  Parallel sides are 18.5 ft and 24.5 ft
Height:  12 - 10.75 = 1.25ft

Area of Trapezium = (1/2)*(Sum of Parallel sides)*height

                            = 1/2 * (18.5+24.5)* 1.25
                            = 1/2 * 43* 1.25 = 26.875     

Total Area = Area of Rectangle + Area of Trapezium

               =  263.375 + 26.875   = 290.25

Area = 290.25 ft²     (D)

A bag contains 5 blue marbles, 6 red marbles, and 9 green marbles. Two marbles are drawn at random, one at a time. What is the p
Leokris [45]
Your answer would be C. 27/190.

This is because the probability of choosing green as the first marble would be 9/20, as there are 20 marbles in total and 9 of those are green.

The probability of choosing a red marble as the second marble would be 6/19, as no red marbles would have been lost if green was picked first, but there would be one less marble in total.

The 'and' rule for probability, the one that is used to determine the probability of P(A) and P(B), is to multiply, so we need to do 9/20 × 6/19 = 54/380 = 27/190.

I hope this helps!
