3 0

Answer:

I'm not sure about the function but here is the answer: 3

Step-by-step explanation:

Well, 75% of 1 is 0.75 + 75% of that + 75% of that and so on until you do it four times. Why four? Well it increases every 30 MINUTES so 30 min + 30 min + 30 min + 30min = 2 hours!

In a field there are cows, birds, and spiders. Spiders have 4 eyes and 8 legs each. In the field there are 20 eyes and 30 legs.
Kitty [74]

Answer:

1 spider, 3 cows, 5 birds.

Step-by-step explanation:

Cows (C): 4 legs, 2 eyes.

Birds (B): 2 legs, 2 eyes.

Spiders (S): 8 legs, 4 eyes.

The number of legs and eyes are given, respectively by:

30 = 4C+2B+8S\\20 = 2C+2B+4S

Multiplying the second equation by -2 and adding it to the first one gives us the number of birds:

30 -40= 4C-4C+2B-4B+8S-8S\\-10 = -2B\\B=5

Rewriting the original equations with B =5:

30 = 4C+2*5+8S\\20 = 2C+2*5+4S\\20 = 4C+8S\\10 = 2C+4S\\C=5-2S

Since the number of cows cannot be negative, and both C and S must be odd numbers, the only possible value of S is 1:

C=5-2S\\S=1\\C=3
