Can anyone answer this question? it would be greatly ! : )

The probability that point falls in the white area is 2/3 or 0.667

Step-by-step explanation:

Consider the provided figure.

As we know there are 360 degrees in a circle.

The diameter divides the circle in two equal half 180° each.

The angle measure of white part in upper half is 180°-60°-60°=60°

The total angle measure of white part in the provided figure is: 180°+60°=240°

Now we need to find the probability that a random selected point falls in the white area

Substitute Number of favorable outcomes=240° and Total number of outcomes = 360° in the above formula.

Hence, the probability that point falls in the white area is 2/3 or 0.667

50 min

step-by-step explanation:

they will be decreasing both their times in half

60 / 2 = 30

40/2 = 20

30 + 20 = 50

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
