How much is 50 feet compared to a person?

explained

Step-by-step explanation:

Well, Average height of man is 5 feet 9 in world wide. Although it may very from country to country. Similarly, avg. height of women in the world is 5 feet 4 inches. Now, comparing 50 feet and men height

1 foot = 12 in

therefore 50 feet= 50*12= 600 inches

whereas, avg men height= 5*12+9= 69 inches

600/69= 8.69

therefore, 50 feet = 8.69 times the height of average men.

similarly,avg women height= 5*12+4= 64 inches

600/64= 9.37

therefore, 50 feet = 9.37 times the average height of women

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
