There is an animal farm where chickens and cows live. All together, there are 84 heads and 210 legs. How many chickens and cows
Ira Lisetskai [31]

1 Chicken have = 2 legs

1 Cow have = 4 legs

No of cows = x

No of chickens = y

Total no of legs = 4x + 2y = 210.............(1)

Total No of heads = x + y = 84................(2)

x = 84 - y....( from (2) )

Substituting the above equation in (1)

4 ( 84 - y) + 2y = 210

336 - 4y + 2y = 210

336 - 2y = 210

-2y = -126

= y = 63

No of cows = 84-63 = 21

∴ <u><em>Total no of cows = 21</em></u>

<u><em>Total no of chickens = 63</em></u>

How to do 15 1/2 - 2 1/10 how to do it
lisov135 [29]

First, you need to make the fractions have the same denominator:

15  1/2        --->       15 + (1/2 x 5)  =   15  5/10

2   1/10       --->       2  1/10

Then you need to subtract them from each other:

  15   5/10                                        

<u>-    2   1/10</u>                   (or)                  15  5/10 - 2 1/10 =   13  4/10

   13   4/10

This gets the answer:   <u>13  4/10</u>

You are designing a container in the shape of a cylinder. The radius is 6 inches. You want the container to hold at least 324π c
goldfiish [28.3K]
Answer: 9 inches

Explaination: The volume of a cylinder, V = (πr^2)H, so H = V/(πr^2).

Using the parameters you specified, H = 324π/[(π)(6^2)] = 324π/36π = 324/36 = 9 inches
