The perimeter of the rectangular playing field is 430 yards.The length of the field is 5 yards less than triple the width. What
Ad libitum [116K]

Answer:

Length = 160 and width = 55 yards

Step-by-step explanation:

Perimeter =  2L + 2W  where L = the length and W = the width.

L = 3W - 5   (given).

So substituting for L is the formula for the perimeter:-

2(3W - 5) + 2W = 430

6W - 10 + 2W = 430

8W = 440

W = 55 yards.

So the Length L = [430 - 2(55]) / 2  = 160 yards.

How do find the measures of angles with a vertex inside or outside circle?
pantera1 [17]

Step-by-step explanation:

Figure %: An angle whose vertex is in the interior of a circle The measure of angle 1 is equal to half the sum of the measures of arcs AB and DE. When an angle's vertex lies outside of a circle, and its sides don't intersect with the circle, we don't necessarily know anything about the angle.

You have two ways to drive home from school: Route A is usually quicker; Route B is
Brilliant_brown [7]

Answer:

0.12 = 12%

Step-by-step explanation:

To find this probability, we need to multiply the probability of getting route B, and the probability of getting home by 4 P.M if we choose route B.

If the probability of choosing route A is 60%, we have that the probability of choosing route B is 100% - 60% = 40%

Then, we have that the probability of getting home by 4 P.M. when choosing route B is 30%, so the final probability is:

P = 40% * 30% = 0.4 * 0.3 = 0.12 = 12%
