The hash marks tell you the triangles are similar and the smaller one is 1/2 the size of the larger one. Then x is half the length of the corresponding segment marked 81.

x = 81/2

x = 40 1/2

___

You may have to write it as 81/2 or as 40.5. Sometimes the answer needs to be in a particular form.

Rabbit populations can double every 30 days. If there are 26 rabbits on a farm, how many rabbits will be on the farm after 240 d

Cerrena [4.2K]

Answer:

7680 rabbits

Step-by-step explanation:

Let y represent the number of rabbits after x days and let x represent the number of days. This is an exponential growth equation in the form:

$y=ab^x$

Since there is an initial value of 26 rabbits on the farm and the rabbits double every 30 days, hence the equation becomes:

$y=26(2^{(\frac{x}{30} )})\\\\for\ 240\ days, i.e\ x=240:\\\\y=26(2^\frac{240}{30} )\\\\y=7680\ rabbits$
