For interest rate question I=p times r times t
17=500 times r times 2
17 divide 1000
then multiply 100 to get percentage
1.7%

Area = 10025.66 square units
Step-by-step explanation:
We are given the following in the question:
The birth rate of a population:
The death rate of a population:
The area between the curve for 0 ≤ t ≤ 10, is given by:

Answer:
X = 97.45 - 42
Step-by-step explanation:
If 42 + X = 97.45, X needs to be 97.45 - 42
you can do the same thing with smaller numbers, for example:
5 + X = 7
7 - 5= 2 and you can check for sure that this is the answer by adding them together 5 + 2= 7 so it's definitely the right answer
so for this question, 97.45- 42 = 55.45 so that's X
you can check that by 55.45 + 42 and if the answer is 97.45 that's the right answer!
I hope that makes sense
Hey there!
1, 8.95*.4= 3.58 was take off. 8.95-3.58= 5.37
$5.37
2.<span>A change from 85 to 72 represents a negative change (decrease) of -15.294117647058824%</span>
All you have to do here is combine like terms.
5x + 9x = 14x
.5 - 2.5 = -2
14x - 2
