If the ratio of surface areas of 2 similar figures is 144/25 ; What is the ratio of their volumes?
kkurt [141]

Answer:

1728/ 125

Step-by-step explanation:

The ratio of corresponding lengths  of the figures = ratio of the square root of their areas.

So ratio of lengths =  12/5.

Now volume is 3 dimensional  so the ratio is the cube  of the lengths

= 12^3/5^3

= 1728/ 125.

The population of a town has grown at an annual rate of 2.7%. How long does it take for it’s population of 18,450 people to doub
charle [14.2K]
It would take 26 years.

The equation will be in the form y = a(1+r)ˣ, where a is the initial population, r is the growth rate as a decimal number, and x is the amount of time.  Using our information we have

y = 18450(1+0.027)ˣ = 18450(1.027)ˣ

We want the population to be doubled; 18450*2 = 36900:
36900 = 18450(1.027)ˣ

Divide both sides by 18450:
36900/18450 = 18450(1.027)ˣ/18450
2 = 1.027ˣ

Using logarithms, we have
\log_{1.027}2=x
\\
\\x=26.017

Help Its math Im stuck!
Romashka [77]
C is correct.


Reasoning: If the top number (numerator) is smaller that the bottom number (denominator), it means it’s smaller than 1. If, on the other hand, the numerator is bigger than the denominator, it means it’s more than 1. If youre ever unsure, devide the numerator by the denominator. This will turn the number into a decimal, and be easier to see. 8/9 = 0.88 repeated, and 3/7 = 0.4285. Therefore 8/9 is larger than 3/7. This can also be written as 8/9 > 3/7.

Good luck!
