Problem

4 Sammy, Teddy, and Ursula ran a 100-meter race. Sammy's time was 15.03 seconds. Teddy's and Ursula's times were 14.7 seconds and 15.003 seconds, respectively. Which statements are true? Circle all that apply. A Teddy ran 0.04 second faster than Ursula. B Teddy came in 3rd place. C Ursula ran 0.027 second faster than Sammy. D The time between the slowest and fastest run was 0.33 second. 5 Kay was trying to triple a salsa recipe. Her recipe for one batch called for 1.232 milliliters of red hot pepper sauce. She thought she added three of that amount for three batches. When people dipped into the salsa, it was too spicy to eat. What could she have done wrong?

Solution

Step 1 :Given that Sammy's time was 15.03 seconds, Teddy's time was 14.7 seconds, and Ursula's time was 15.003 seconds, we need to compare each person's time to the others and see which statements are true.

Step 2 :Comparing the times, we find that Teddy did not run 0.04 second faster than Ursula, Teddy did not come in 3rd place, Ursula did not run 0.027 second faster than Sammy, and the time between the slowest and fastest run was not 0.33 second. Therefore, none of the statements A, B, C, and D are true.

Step 3 :\(\boxed{\text{None of the statements A, B, C, and D are true}}\)

Step 4 :For the second question, Kay's recipe for one batch called for 1.232 milliliters of red hot pepper sauce. She thought she added three of that amount for three batches. When people dipped into the salsa, it was too spicy to eat.

Step 5 :If Kay added three times the tripled amount of red hot pepper sauce, she would have added approximately 11.088 milliliters, which is much more than the correct tripled amount of 3.696 milliliters. This could be why the salsa was too spicy to eat.

Step 6 :\(\boxed{11.088}\)
