The distance between the points A to B is 899.9 feet. After rounding off the nearest integer we get 900 feet as the final answer.
Given we know that CD is perpendicular to AD.
The distance between CD is 139 feet.
As from points A the boat's crew measure the angle of elevation to the beacon as 6°
therefore, m∠A = 6°
Another time the angle of elevation is measured from point B which is 19°.
therefore, m∠DBC = 19°
tan 19° = CD/BD
BD = CD/tan19°
BD = 136/tan 19°
now for tan 6° = CD/AD (tangent is opposite over adjacent)
AD = CD/tan 6°
AD = 136/tan 6°
AB = AD ₋ BD
AB = 136/tan 6° ₋ 136/tan 19°
AB = 1295.2 ₋ 395.3
AB = 900 feet
hence the distance from point A to B is 900 feet.

Answer:
"6 out of 10 people" means the ratio of class:no_class is 6:4
990/10 = 99, the smallest the "class" and the "no_class" add up to is 10. And, generally, the total divides with that nicely, as in this case.
99(6) = 594 ----------- probably class
99(4) = 396 ------------------ probably no class
Total = 990

Answer:
$25.80
Step-by-step explanation:
First find the price of the meal with sales tax. Multiply 6.75% by $72.50.
72.50 * 0.0675 = 4.89
Add this value onto 72.50.
72.50 + 4.89 = 77.39
Divide this amount by 3.
77.39 / 3 = 25.7966...
Round this to the nearest hundredth because we're dealing with money.
$25.80 is how much each person should pay.
One-fourth + one-sixth + one-third
<span>three plus two plus four /12 = 9/12 = 3/4 </span>
<span>So, balance = 1/4 = 1/4 times 20 = 5 pies which is the answer!
