Answer:
183.4286 lbs
Step-by-step explanation:
given that the population of weights for men attending a local health club is normally distributed with a mean of 178-lbs and a standard deviation of 25-lbs.
Total weight in the lift should not exceed 6420 lbs
No of persons limited = 35
Hence average weight of the person that should be below
If the average exceeds 183.4286 pounds then the elevator would be considered overloaded.
Answer:
Part A:
The surface area of a cylinder is given by
A= 6πr² if h= 2r
Part B:
Total Cost of covering the cylinder = Rate *2πrh + rate*2πr²
Cost of covering only the side = Rate *2πrh
Step-by-step explanation:
Part A:
The surface area of a cylinder is given by
A= 2πrh + 2πr²
Where h= height and radius = r
But we have the height twice as radius so h= 2r
So putting h= 2r we get
A= 2πr(2r) + 2πr²
A= 4πr² + 2πr²= 2πr²(2+1) = 2πr²(3)= 6πr²
Part B:
Cost = Rate * area of the wall + rate * area of the top and bottom
Cost = Rate *2πrh + rate*2πr²
Where area of the top and bottom= πr² +πr² =2 πr²
and area of the side = 2πrh
Multiplying both with the rate and then adding would give the total cost of materials needed to cover the outside of the cylinder and from top and bottom as well.
If you do not need to cover top and bottom then the expression would be
Cost of covering only the side = Rate *2πrh
Part C:
Already done above.
Answer:
<u>Amanda can make 1.5 or 3/2 of batches of pancakes with 11/22 of a cup of milk.</u>
Step-by-step explanation:
1. Let's review the information given to us for answering the question correctly:
Amount of milk Amanda use for a batch of pancakes = 1/3 cup
2. How many batches can she make if she only has 11/22 of a cup of milk left?
Let's simplify 11/22, dividing by 11 the numerator and the denominator,
11/22 = 1/2
Now, using the Rule of Three Simple, we can calculate the answer to this question, this way:
Number of batches = (1/2 * 1)/1/3
Number of batches = 1/2 / 1/3
Number of batches = 1/2 * 3/1 (Taking the reciprocal)
Number of batches = 3/2 = 1.5
<u>Amanda can make 1.5 or 3/2 of batches of pancakes with 11/22 of a cup of milk.</u>
