Answer:
The total simple interest accumulated in the separate checking account after two years is $450. The rate of interest on the 6-month certificate of deposit was 22%.
Step-by-step explanation:
The general formula for calculating simple interest is as follows: A=P(1+rt), where 'A'=the total amount; 'P'=the principal amount; 'r'=rate; 't'=time, in years. Given that the simple interest is moved into a separate account at the end of each year, you just need to calculate the amount of interest collected on the principal amount of $5000 after each year at a rate of 4.5%. Putting these values into the equation and solving for 'A' gives you a value of $5225, or $225 per year which is $450 over two years. In order to find the rate in the second problem, use the same formula, substituting $1900 for 'P', $2109 for 'A' and 0.5 for 't', in order to solve for 'r' which will be 22%.
Answer:
13.15
Step-by-step explanation:
They give you the lengths of the sides in the problem. NM = sqrt 2, LK = 2sqrt 2, LM & NK = sqrt5 Perimeter is to add all of the sides so: sqrt2 + 2sqrt2 = 3sqrt2. sqrt5 + sqrt5 = 2sqrt5. Together it is 3sqrt2 + 2sqrt5It's letter C 3sqrt2 + 2sqrt5
A.) -540
Sum = N (first number + last number) / 2
N = count of consecutive numbers. Had the numbers included 1, then, N would have been 33. Since its range is 7 - 33 then 33 - 7 + 1= 27.
N = 27
Sum = 27 (-33 - 7) / 2
sum = 27 (-40)/2
sum = -1080 / 2
sum = -540
