Theresa bought a new desktop computer. One side of the desktop screen is 14 inches and the other side is 18 inches. What is the length of the diagonal of the desktop screen? Answer choices are rounded to the nearest inch. RATIONALE We can use the Pythagorean Theorem to calculate the length of a diagonal. The variables a and b represent the sides of the computer, and c represents the diagonal. First, substitute 14 for a and 18 for b. (Note that we could also substitute 18 for a and 14 for b...

If $15,000 is invested at 6.5% annual interest compounded annually, how long would it take for the account balance to reach $50,000? Round your answer to the nearest tenth. RATIONALE To find the answer, use the formula for compound interest and solve for t: where: A = 50,000 P = 15,000 r = 6.5% or 0.065 n = 1 To begin, substitute the known values and simplify the formula first by adding the values in the parentheses and dividing both sides by the coefficient. To undo the variable expo...

Polly is curious if she gets better gas mileage when she uses the more expensive gasoline at the gas station. She designs an experiment in which she uses each type of gasoline exclusively for 3 months. Which statement is true of this experiment? RATIONALE The type of gasoline used is the explanatory variable, because it is the variable that Polly controls. Her gas mileage is the response variable, because it is the variable that will be observed and that may change in response to the type o...

Suppose $18,000 is deposited into an account paying 8.5% interest, compounded continuously. How much money is in the account after 10 years if no withdrawals or additional deposits are made? RATIONALE If an account is being continuously compounded, the following formula can be used: where: P= principal balance = 18,000 r = interest rate = 5.25% = 0.085 t = number of years = 10 Substitute the known values and solve for A, the account balance after 10 years: Report an issue with this ques...
