40 dogs and parrots in total (dogs + parrots = 40 in total) theres 130 legs, how much dog and parrots are there (need steps)

charle [14.2K]

Answer: There are 32 dogs and 1 Parrot

Step-by-step explanation: I had a question like this in a math class. What you first do is to recognize that- parrots have 2 legs and dogs have 4. We can do 130/2 = 65 and 130/4= 32.5. Now we know that if there was only one animal, there would be 65 parrots, and 32 dogs- one with half of the legs. Since there is a .5 for the dogs, if we put in one parrot, it would mean that there is exactly 130.

(32 x 4)+(2x1) = 130. There are 32 dogs and 1 Parrot. I hope this answer is ✅ and helps, i just joined the community and this is the first person I answered. Good Luck!!

F:x→(x+1/x+3), x≠3 and g:x→（6/x-2), x≠2, find f²(4) and g²(1/2)

Sveta_85 [38]

Answer:

$f^2(4) = (\frac{25}{49})\\g^2(\frac{1}{2} ) = 16$

Step-by-step explanation:

Here, given:

$f(x) = (\frac{x+1}{x+3} ), g(x) = (\frac{6}{x-2} )$

Now, here to find the values of $f^2(4), g^2(\frac{1}{2})$

As we know: $f^n(x) = (f(x))^n$

Now, substituting x = 4 in f(x):

$f(4) = \frac{4 +1}{4+3} = \frac{5}{7} \\\implies f^4 = (f(4))^2 = (\frac{5}{7} )^2 = \frac{25}{49} \\\implirs f^{(4)} = ( \frac{25}{49})$

Now, substituting x = 1/2 in g(x):

$g(\frac{1}{2} ) = \frac{6}{\frac{1}{2}-2} = \frac{6}{-\frac{3}{2}} \\\\ g(\frac{1}{2} ) = -6\times (\frac{2}{3} ) = -4\\\implies g^2{(\frac{1}{2}) = ( g(\frac{1}{2} ))^2 = (-4 )^2 =16 \\\\\implies g^2{(\frac{1}{2}) = 16$
