in 1990, the Leaning Tower of Pisa was closed to the public due to safety concerns. The tower reopened in 2001 after a 10-year project to reduce its tilt. Engineers' efforts were successful and resulted in a tilt of 5°, a reduction from 5.5°. Suppose you drop something from the tower at a height of 150 ft, as shown below. How far from the base of the tower will it land? Round to the nearest foot.

yes

step-by-step explanation:

the correct answer is 5 6 and 7

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
