Answer:
≈ 1468.59223 in squared
Step-by-step explanation:
1) A=2AB+(a+b+c)h
2) AB= square root of s(s﹣a)(s﹣b)(s﹣c)
3) s=a+b+c / 2
4) A=ah+bh+ch+1 / 2 square root of﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4
5) 18·22+18·22+18·22+1 / 2 x the square root of ﹣184+2·(18·18)2+2·(18·18)2﹣184+2·(18·18)2﹣184≈1468.59223
≈ 1468.59223 in squared
Hope this helps :)
The ladder forms the hypotenuse of a right triangle. Solve for a
<span>a^2 + b^2 = c^2 </span>
<span>a^2 + 9^2 = 18^2 </span>
<span>a^2 + 81 = 324 </span>
<span>a^2 = 243 </span>
<span>a = 15.589 = 15.6 feet</span>
Answer:


Step-by-step explanation:
- The freight elevator can hold a maximum weight of 3500 pounds
- The delivery man weighs 200 pounds
- Each carton weighs 48 pounds
Let the number of cartons he can safely put on the elevator at one time=n
Total weight of Carton=48n
Since the weight of the man and the cartons combined must not be more than 3500 pounds,
Therefore,an inequality that represents the situation is:

We can solve for n if required

The delivery man can safely carry 66 Cartons.

Answer:
the events of using Brand Z computers and quitting your job are independent.
Step-by-step explanation:
Let A be the event that the population used Brand Z computers and let B be the event that the population quit their jobs.
We are told that 50% of the population used Brand Z computers last year. Thus, the probability of event A is;
P(A) = 50% = 0.5
Also, we are told that 4% of the population quit their jobs last year. Thus the probability of event B is;
P(B) = 4% = 0.04
Since 2% of the population used Brand Z computers and then quit their jobs. Then the probability of the population used Brand Z computers and then quit their jobs is;
P(A ∩ B) = 2% = 0.02
From the law of independent events, if A and B are to be independent events, then;
P(A ∩ B) = P(A) × P(B)
Thus;
P(A ∩ B) = 0.5 × 0.04 = 0.02
This is same value as what was given in the question, thus the events of using Brand Z computers and quitting your job are independent.
