Radius is half of the diameter so it's 7 for the diameter.
27= 3x3x3
54 = 3x3x3x2
so 27/54 = 3x3x3 /<span>3x3x3x2 by simplifying = 1/2</span>

Answer: There are 99 three-legged-cows and 28 chickens.
Step-by-step explanation:
Let x be the number of three-legged-cows and y be the number of chickens.
Number of legs in chicken = 2
The according to the question, we have the following equations :-
Multiplying 2 to the equation (1), we get
Now, subtract equation (3) from (2), we get
Put x= 99 in (1), we get
Hence, there are 99 three-legged-cows and 28 chickens.
The expression is:
Why?
From the statement we know that the spaceship travels 3 times faster each minute that it traveled during the minute before, it can be expressed using an exponential function, its base will be the starting speed (during the first minute).
The expression will be:
