Question

Julia and Kajal make deliveries on their bicycles. For each delivery, they need some time to get ready, and then they each ride at a constant speed. Julia takes 40 minutes to make a delivery 5 kilometers away. She uses 10 minutes of the delivery time to get ready. The following equation gives the time it takes Kajal to make a delivery (in minutes) as a function of the distance of the delivery (in kilometers). t = 15 + 6d. Who takes more time to get ready?

1) Julia
2) Kajal

Answer 1

The appropriate number of significant figures in the result of multiplying 15.234 and 15.208 is 3.

Step-by-step explanation:

The appropriate number of significant figures in the result of 15.234 × 15.208 is 3.

To determine the number of significant figures in the product of two numbers, we count the number of significant figures in each number and use the smallest count as the number of significant figures in the result.

In 15.234, there are 4 significant figures, and in 15.208, there are 5 significant figures. Therefore, we take the smallest count, which is 3 significant figures, as the number of significant figures in the result.
