Answer:

11:10

Step-by-step explanation:

If the scale factor for similar shapes is a:b

We know the ratio of the sides is a:b

areas is a^2 : b^2

volumes is a^3 : b^3

The ratio of the areas is 121:100

Take the square root to find the scale factors

sqrt(121) : sqrt(100)

11:10

This is also the ratio of the sides

dexar [7]

Answer:

5.5 years

Step-by-step explanation:

24900 times 6.75% = 1,680.75

so this is how much it goes down per year, but we have to find it were the price reaches 15900. so 9000-1680.75=

7,319.25( one year)

7,319.25-1680.75 = 5,638.5 (second year)

5,638.5-1680.75= 3,957.75 (third year)

3,957.75-1680.75 = 2,277 (fourth year)

2,277-1680.75= 596.25 (fifth year)

Squaring a number and adding one will always produce an even number.

False. Squaring any rational, whole number, will always give you a even number. So if you add one to the number, you will get a odd number.
