Answer: The ladder should be at least 34 feet long (approximately)
Step-by-step explanation: Please refer to the diagram attached for details.
The chimney is depicted as line AB (33 ft). The distance from the base of the chimney to the ladder is depicted as line BC (3 ft). The ladder is placed such that it forms an angle of 75.5 degrees with the floor. Hence the required length of the ladder needed is shown in the diagram as line AC (line b). The resulting diagram now has an opposite (33 ft) and an hypotenuse (b) which is yet unknown.
To calculate line b, we shall apply the trigonometric ratio as follows;
SinC = opposite/hypotenuse
Sin 75.5 = 33/b
By cross multiplication we now have
b = 33/Sin 75.5
b = 33/0.9681
b = 34.087
Therefore the required length of the ladder is approximately 34 feet.

Answer:
D is 36080
Step-by-step explanation:
D is the largest since A is 3.608, B is 360.8, C is 36.08
When dividing, the smaller decimal points will be larger, but if you multiple, the numbers shrink.
The median is the value that can be found in the middle of any data set. After plotting the values on the line plot (shown in the attached image), we can write out our data (shown under neath the line plot).
Then, we start by crossing off one value on each side of the data to work our way towards the middle. Once we come to the middle, we see that there are two values in the middle: 6 and 6.
To find the median when we have two values in the middle, we must add them, then divide by two.
6 + 6 = 12
12 ÷ 2 = 6
So, the median for this data set is 6.
