What is the length of ad¯¯¯¯¯¯¯¯? ad≈ enter your answer as a decimal rounded to the nearest hundredth.

First, you need to calculate the hypotenuse, this is possible because we know the value of one angle, 72 degrees, and one angle is 90 degrees.

sin72 = DC / AC , sin of an angle = opposite / hypotenuse

AC = DC / sin72, we must calculate the value of sin72 by calculator, and sin72 = 0,254

AC = 6/0,254 = 23,62

From here, we use the Pythagorean theorem to calculate AD, like such:

AD^2 = AC^2 - DC^2

AD^2 = 23,62^2 - 6^2

AD^2 = 557,90 - 36 = 521,9

AD = square root of 521,9

AD = 22,845 = 22,8

It seems a bit weird, but that's what the math says. Hope this helps!

for a it would be 24 children.

for b i don't understand the question. is it saying for each individual person they pick 5 reds to 7 greens or is it the whole group. clarify and i hope this can you.

step-by-step explanation:

all group life insurance is term insurance. actually it is annual renewable term and it is rated on the average age and claims experience of the entire group, which is called "experience rating." remember, this type of insurance has a 31-day grace period and is convertible to whole life upon leaving employment. a contributory group plan requires that both the employer and the employees pay part of the premium. at least 75% of those eligible must participate, so the group is sure to get most of the healthy employees as well as those that are sick.
