The difference of the blue crab population From 1990-1997, the average was (800+750)/2 = 775; and from 1989-2009: (350+350)/2 = 350. I predict that from 2010 to 2020 the population will increase to about 500 because it seems to go on trends of increasing and decreasing.
In order to solve the formula

in terms of d, you simply have to divide both sides by pi:

The total height of the earring is the sum of the diameters of the circles. Given their circumferences, the diameters are

So, the total height is

You are correct, C) 4x = 12.
So, if 4 people are eating 12 pieces of pizza, simply divide 12 by 4 and there's your answer!
12 / 4 = 3 Each person gets 3 slices of pizza.
Answer:

Step-by-step explanation:
We know that for principal amount P , time period T and rate of interest
, simple interest is given by
.
Here ,

To find : simple interest rate i.e., 
On putting values of
in formula , we get 

Now we need to round off the answer to the nearest tenth .
So, simple interest rate is % =
=
