Acircle is inscribed in a square. a point in the figure is selected at random. find the probability that the point will be in the part that is not shaded.
a.25%
b.10%
c.20%
d.5%

 The correct option is (C) 20%.

Step-by-step explanation:  Given that a circle is inscribed in a square and a point in the figure is selected at random.

We are to find the probability that the point will lie in the part that is NOT shaded.

Let a units be the side length of the square.

Then, the area of the square will be

Also, the radius of the circle is equal to the half of the side length of the square. So, the area of the circle will be

So, the area of the part that is not shaded is given by

Therefore, the probability that the selected point is not in the shaded part is given by

Thus, the required probability is 20%.

Option (C) is CORRECT.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

28

because that's the answer
