Evaluate 3ab for a=2 and b=3
vampirchik [111]

Answer:

18

Step-by-step explanation:

For this problem, we will simply plug in the values of a and b into the respective variables in the expression 3ab to "evaluate" the expression.

a = 2; b = 3

3ab

Note, that when variables like a and b are smashed with a constant, the use of multiplication is in play.

3ab = 3 * a * b

With this in mind, let's plug in the values of a and b into the expression.

3ab

= 3 (2) (3)

= 3 (6)

= 18

Hence, 3ab evaluated when a=2 and b=3 is 18.

Cheers.

Clarke borrows $16,000 to buy a car. He pays simple interest at an annual rate of 6% over a period of 3.5 years. How much does h
mr Goodwill [35]

Answer:

The total amount he will altogether be: $19360

Step-by-step explanation:

Given

  • Amount Borrowed = P = $16,000
  • Interest rate = r =  6% = 6/100 = 0.06
  • Time period = t = 3.5 years

To determine

  • Amount of interest = I
  • Total Amount altogether = A

Using the formula

I = Prt

substituting the values P = 16,000, r = 0.06, t = 3.5 years

I = 16,000 × 0.06 × 3.5

I = $3360

Thus, the interest amount = $3360

Therefore, the total amount he will altogether:

A = P + I

A = 16,000 + 3360

A = $19360

Therefore, the total amount he will altogether be: $19360
