Answer:
20
Step-by-step explanation:
Answer:
5 : 3
Step-by-step explanation:
Given in the question that,
total number of animal feet = 26
number of pig's feet = 20
number of chicken's feet = 6
As we know that pig have four legs and chicken have 2 legs so,
number of pigs in the farm = 20/4 = 5
number of chickens in the farm = 6/2 = 3
Questions says that there are 8 heads so we can confirm our calculations as
<h3>5 + 3 = 8</h3><h3 />
The ratio of the number of pigs to the number of chickens is
<h3>5 : 3 </h3>
Answer:
The required answer is .
Step-by-step explanation:
The given differential equation is
Substitute u=x-y+1 in the above equation.
Using variable separable method, we get
Integrate both the sides.
Substitute u=x-y+1 in the above equation.
Therefore the required answer is .
Let x be the width of the frame.
Then, x + 3 is the length of the frame.
The area of a rectangle is the product of its length and its width.
So, x(x+3) = 40
x^2 + 3x = 40
x^2 + 3x - 40 = 0
(x-5)*(x+8)=0
x-5 = 0 or x+8 = 0
x = 5 or x = -8
x = 5
The width is 5 and the length is 5 + 3 = 8
