Answer:

Becky’s THR would be between 157 bpm and 190 bpm during the physical activity.

Explanation:

From the given information;

Since Becky is 16 years old, in order to evaluate the MHR, we deduct the age from 220.

Therefore, the evaluation of the maximum age-related heart rate MHR = 220 - 16 = 204 beats per minute

We are being told that she then multiplies her MHR by 77% and 93%.

i.e

77% level: 204 × 0.77 = 157 bpm

93% level : 204 × 0.93 = 190 bpm

The evaluation indicates that the vigorous-intensity physical activity of Becky at 16 years old will need the target heart rate to remain between 157 bpm and 190 bpm during the physical activity.

Ira Lisetskai [31]

Answer:

The correct answer will be option-C

Explanation:

Meat slicers are used in the meat shops and used to prepare a variety of deli items.

While slicing the meat, some remnants of meat get stuck in blades which attracts a lot of microorganisms to grow. If the same unwashed slicer is used again to cut the meat will lead to contamination of the meat and will cause a certain disease.

Therefore, the person before reusing the slicer must clean and sanitize the slicer with slicer sanitizer so that no disease could spread from the contaminated slicer.

Thus, Option-C is the correct answer.
