Answer: 11 1/2 ÷ 2 1/4 is not equal to 6, it is an overestimate.
Step-by-step explanation:
11 1/2 ÷ 2 1/4 = 6
First step: convert the improper fraction to a proper fraction
11 1/2= 23/2
2 1/4= 9/2
The question can be written as:
23/2 ÷ 9/2
=23/2 × 2/9 ( 2 cancels out 2)
= 23/9
=2.56
Therefore, 11 1/2 ÷ 2 1/4 is not equal to 6, it is an over estimate.
I hope this helps.
Answer:
The ladder has to be 65 feet long to the nearest foot.
Step-by-step explanation:
The height of the chimney from the ground is the sum of the height of the wall and the height of the chimney.
Therefore, the height of the chimney from the ground = (30 + 33) = 63 feet.
Now, the ladder makes a right triangle with the ground and the chimney and the ladder makes an angle of 75.5° with the ground.
Therefore, using trigonometry we can write,

⇒ The length of the ladder = 65 feet.
Hence, the ladder has to be 65 feet long to the nearest foot. (Answer)
