Answer:
Number of Years to Double= 10.62 years
Step-by-step explanation:
<u>First, we need to calculate the real annual interest rate:</u>
Real annual interest rate= {[(i/12)+1]^12} - 1
Real annual interest rate= [{(0.064/12) + 1]^12 - 1}
Real annual interest rate= 0.0659
<u>Now, we need to use the rule of 72. The rule of 72 is a means of estimating the number of years it takes for an investment or your money to double. </u>
<u></u>
Number of Years to Double= 70/Annual Rate of Return
Number of Years to Double= 70/6.59
Number of Years to Double= 10.62 years
Answer:
7/25
Step-by-step explanation:
Probability = # of favorable outcomes / # of possible outcomes
Favorable outcomes = # of blue and yellow marbles
There are 3 yellow marbles and 4 blue marbles
There are 7 blue and yellow marbles so the favorable outcome is 7
Possible outcomes = total number of marbles
12 + 3 + 6 + 4 = 25
There are a total of 25 marbles
So possible outcomes = 25
If probability= favorable outcomes / possible outcomes then the probability of pulling a blue or yellow marble is 7/25
W+b=30
5.50w+8.75b=204
Use simultaneous equations to solve. Replace w with 30-b and plug into the second equation.
5.50(30-b)+8.75b=204
165-5.5b+8.75b=204
3.25b=39
b=12

Answer:
Section C
Step-by-step explanation:
A rhombus is basically a tilted square :)
A rhombus has all equal sides no matter what making it an equilateral
It also has two pairs of sides that are parallel making it a parallelogram
Meaning it is both a equilateral and parallelogram and belongs in section C
