Bridgette deposited $3,300 in a savings account with simple interest. Six months later, she had earned $165 in interest. What was the interest rate?

The interest rate is 10%.

Step-by-step explanation:

Interest = principal * rate * time

time is always in years. 6 month = 0.5 year

1.) 165 = 3300 * r * 0.5

2.) multiply 0.5 and 3300

165 = 1650r

3.) divde 1650 to each side

0.1 = r

0.1 = 10%

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
