This year there are 900 rabbits which represents 200% of last year's population, means that last year the number of rabbits was:
x = 900 (100/200) = 450 rabbits.
The mathematical expression can be derived by a simple rule of three.
So, for last year the population was 450 rabbits.
Answer:
Length = 45.37 in
Width = 30.56 in
Step-by-step explanation:
Let the width of the picture be 'w' inches.
Given:
Perimeter of the picture is, 
Length is 15.75 inches shorter than twice the width. So, length is:

Now, we know that the perimeter of a rectangular shape is given as the sum of all of its side. So, the picture is also of rectangular shape and hence the perimeter is given as:

Plug in the values of 'l' and 'P' and solve for 'w'. This gives,

Therefore, the width of the rectangular picture is 30.56 inches.
Length of the picture is, 
So, length of the picture is 45.37 inches and width is 30.56 inches.
Answer:
y=sin(ln(x))
Step-by-step explanation:
First, we have to order the terms as follows and express y' as dy / dx:

Then, we have to integrate

with this solution after integration:

Then, we have to reorder

and applied Sin function on both sides

To define the value of C, we use the known point y(1)=0 and replace in the equation

The function that proves that differential equation is

26, 37. Add by odds like 1,3,5,7,9,11
Answer:
61 students
Step-by-step explanation:
When finding the percentage of a number, you can simply cross multiply and divide:
we can remove the percentage symbol…

Now 6100 divided by 100 is:
61
hope this helps!
