Height of the trapezoids = sqrt (17^2 - 8^2) = 15cms
base = 19 cms

(b) area of each trapezoid =  15/2 (35 + 19) =  405 cm^2

Total area painted blue = 2*405 = 810 cm^2

(c)  length of the edges of one trapezoid = 35 + 19 + 2(17) = 88 cms
So one piece of  sandpaper ( can sand up to 80 cm) will not be enough to sand all of the edges.

A bowl of fruit is on the table. It contains 5 apples, 2 oranges, and 2 bananas. Christian and Aaron come home from school and r
Sholpan [36]

The probability that both grab oranges would be = \frac{1}{36}

Step-by-step explanation:

Given,

A bowl contains,

Apples = a = 5

Oranges = o = 2

bananas = b = 2

Total fruits in bowl = x = a + o + b = 5 + 2 + 2 = 9

Now, Christian and Aaron come home from school and randomly grab one fruit each.

The probability of first selecting orange would be = \frac{o}{b} = \frac{2}{9}

Now, the oranges left would be 2 - 1 = 1

and total fruits would be = 9 - 1 = 8

Hence, the probability of selecting second orange would be = \frac{1}{8}

Therefore, the probability that both grab oranges would be = \frac{1}{8} * \frac{2}{9} = \frac{1}{36}
