Here are the solutions to the visible questions from the image. Question 1, 2, 3, 4: The questions regarding the amount of flour, salt, oven temperature, and baking time require specific recipe information which is not provided in the image. Therefore, these questions cannot be answered. Question 5: Sara must deliver a pizza 6 kilometres from her store. She must deliver the pizza within 10 minutes before it turns cold. She will drive at an average speed of 70 km/h. Determine if the pizza will still be warm at delivery. Step 1: Identify the given values. Distance (d) = 6 km Maximum allowed time (t_max) = 10 minutes Average speed (v) = 70 km/h Step 2: Convert units to be consistent. Convert the maximum allowed time from minutes to hours. t_max = 10 minutes × 1 hour60 minutes = (10)/(60) hours = (1)/(6) hours Step 3: Calculate the actual time taken for delivery. Use the formula t = (d)/(v). t = 6 km70 km/h t = (6)/(70) hours t = (3)/(35) hours Step 4: Convert the actual time to minutes for comparison. t = (3)/(35) hours × 60 minutes/hour t = (180)/(35) minutes t ≈ 5.14 minutes Step 5: Compare the actual delivery time with the maximum allowed time. The actual delivery time is approximately 5.14 minutes. The maximum allowed time is 10 minutes. Since 5.14 minutes < 10 minutes, the pizza will be delivered within the time limit. The pizza will still be warm at delivery. Yes, the pizza will still be warm.
