Write an arithmetic expression that calculates the yearly interest earned on a amount that's stored in a decimal variable named

principalAmount at an interest rate that's stored in a decimal variable named interestRate. (The interest rate is stored as a decimal fraction like .055 for a rate of 5.5%.)

Answer:

yearlyInterest = principalAmount * interestRate * year

Step-by-step explanation:

The general formula for interest is given as:

(principal * rate * time)/100

but in this case the rate has been converted to decimal and the time is in year.

The principal is represented as principalAmount

The rate is represented as interestRate

The time is represented as year

So, the arithmetic expression is to multiply every term together without dividing by 100 since rate is expressed as a decimal fraction.

What is the common ratio of the following geometric sequence 5/12, 1/4,3/20,9/100,27/500
suter [353]

Answer:

3/5

Step-by-step explanation

Ratio =second term divided inti first term a2/a1

a1=5/12      a2=1/4

1/4: 5/12  is the same as      1/4*12/5 =12/20 = 3/5

5/12*3/5 = 15/60 = 1/4

1/4* 3/5 =3/20

3/20*3/5 =9/100

9/100 *3/5 = 27/500..........

10. Both x and y vary inversely with each other. When x is 10, y is 6,which of the following is not a possible pair of correspon
elena55 [62]

9514 1404 393

Answer:

  D) 45 and 1.2

Step-by-step explanation:

The "varies inversely" relationship is described by the equation ...

  y = k/x . . . . . . y varies inversely with x (and vice versa)

The value of k can be found from known values of x and y:

  xy = k . . . . . . multiply the above equation by x

  (10)(6) = k = 60 . . . . using the given values

__

To check if a given pair of numbers satisfies ...

  y = 60/x

you can multiply them together to see if the product is 60.

  (A) 12×5 = 60

  (B) 15×4 = 60

  (C) 25×2.4 = 60

  (D) 45×1.2 = 54 . . . . . not a possible pair of corresponding values.

45 and 1.2 are not a possible solution for x and y.
