Question

the calibration of this graduated cylinder is 50 ml. we can estimate to the nearest 10 ml. what is the volume of liquid shown? 755 ml 740 ml 715 ml 700 ml

Explanation:

Step1: Analyze the graduated cylinder

The graduated cylinder has markings at 600 mL, 700 mL, and 800 mL. The interval between 700 mL and 800 mL is divided (since we can estimate to nearest 10 mL, and the total calibration between 600 - 800? Wait, no, the calibration is 50 mL? Wait, maybe the scale: from 600 to 700, 700 to 800. Let's see, the liquid level is between 700 and 800? Wait, no, the options: 755, 740, 715, 700. Wait, maybe the scale between 600 and 700, 700 and 800. Wait, the problem says "calibration of this graduated cylinder is 50 mL" – maybe the major divisions? Wait, no, the key is estimating to nearest 10 mL. Let's look at the liquid level. The line is between 700 and 800? Wait, no, the options: 740 is a candidate. Wait, let's think: if we can estimate to nearest 10 mL, so the possible volume should be a multiple of 10? Wait, no, estimate to nearest 10, so we look at the meniscus. Wait, maybe the scale: between 600 and 700, 700 and 800. Wait, the liquid is at, say, 740? Wait, the options: 740 mL is one. Let's check: 700 + 40? Wait, maybe the graduation: from 700, each 10 mL? Wait, the problem says "estimate to the nearest 10 mL". So the correct answer should be 740 mL? Wait, let's see the options. The options are 755, 740, 715, 700. Estimating to nearest 10 mL, so 740 is a multiple of 10? Wait, 740 is 7410, yes. 755 is 75.510, 715 is 71.510, 700 is 7010. Wait, but maybe the liquid level is at 740. Let's confirm: the graduated cylinder has 600, 700, 800. The liquid is between 700 and 800, closer to 740? Or maybe the scale between 700 and 800 is divided into 10 mL increments? Wait, the problem says "calibration of this graduated cylinder is 50 mL" – maybe the total capacity? No, the key is estimating the volume. So the correct answer is 740 mL? Wait, let's check the options. The option B (if it's a multiple choice) is 740 mL. So:

Step1: Identify the scale

The graduated cylinder has markings at 600 mL, 700 mL, and 800 mL. We estimate to the nearest 10 mL.

Step2: Estimate the liquid level

The liquid level is between 700 mL and 800 mL? Wait, no, maybe between 700 and 800, but the options: 740 is a reasonable estimate (since 740 is 40 mL above 700, and if the scale allows estimating to 10 mL, 740 is a valid estimate). Among the options, 740 mL is the one that makes sense for a nearest 10 mL estimate.

Answer:

740 mL (assuming the option is, for example, B. 740 mL)
