Let X be birds = ?
Y be beasts = ?
heads = 60
feet = 200
feet of birds = 2
feet of beast = 4
From data we come to know that
total animals = X+Y=60____1
total feet = 200 = 2X + 4Y_____2
from equation 1 X= 60-Y
put this value of X in equation 2
2(60-Y) + 4Y = 200
120 - 2Y + 4Y = 200
2Y= 200 - 120
2Y = 80
Y = 40
Now from value of Y we can calculate X
X + Y =60
X + 40 = 60
Or X = 20
The number of beasts is equal to 40 where as number of birds is equal to 20.
Answer:
8 hours for math and science each
Step-by-step explanation:
4 x 8 = 32
3 x 8 = 24
32 + 24 = 56 hours
- You need to keep what you multiply, (ex. 8), the same as you work through this problem.
- Such as this problem, sometime the best methods are to just guess and check. This means to think of a number that is reasonable and try it. For example, if you try 5 and you see it is too low, go higher. Keep doing this and you would have got to 8 eventually.
What dose it give you is there an image to this prob
Answer:
Below.
Step-by-step explanation:
The number of combinations of 7 from 32 = 32! / 7! (32-7)!
= 3365856
So it is 1/ 3365856 = 0.000000297
or about 3 in 10,000,000.
