Answer:

1:144

Step-by-step explanation:

if each floor is 15 feet, the whole building is 60 feet tall. so it does have a scale of 5 inches:60 feet but if you simplify that, its 1 inch: 12 feet, so you convert feet into inches by multiplying by twelve, which gives you a scale of 1:144 inches

This is known as Einstein's proof, not because he was the first to come up with it, but because he came up with it as a 15 year old boy.

Here the problem is justification step 2.  The written equation

BC ÷ DC = BC ÷ AC

is incorrect, and wouldn't get us our statement 2, which is correct.

For similar triangles we have to carefully pair the corresponding parts to get our ratios right:

ABC ~ BDC means AB:BD = BC:DC = AC:BC so BC/DC=AC/BC.

Justification 2 has the final division upside down.

PLEASE HELP MEEEEE
Elena-2011 [213]

Answer:

a = 36 and a = 27

Step-by-step explanation:

The geometric mean of two numbers is the square root of the product of the two numbers.

Say for example we have the numbers x and y, the geometric mean z is mathematically;

z = √xy

For the first question, our z is 12, x and y are 4 and a respectively.

12 = √4a

square both sides

144 = 4a

a = 144/4

a = 36

For the second question

z is 9, x and y are 3 and a respectively

9 = √3a

square both sides

81 = 3a

a = 81/3

a = 27
