33. Right.

49. Sorry, but I couldn't find the answer to this one (except I'm sure it's not b).

Still need help with #49, but thank you

You're welcome

Please post # 49 again. Perhaps another tutor can help you then.

To calculate Brenda's BMI (Body Mass Index), we need to use her height and weight.

BMI is calculated using the formula: BMI = (weight in pounds / (height in inches)²) x 703

Let's convert Brenda's measurements to the appropriate values:
- Height: 5 ft 6 in = (5 x 12) + 6 = 66 inches
- Weight: 140 lbs

Now we can plug these values into the formula:
BMI = (140 / (66)²) x 703
= (140 / 4356) x 703
= 0.032109 nine (rounded to five decimal places)
= 22.59 (rounded to two decimal places)

Therefore, Brenda's BMI is 22.59. So the correct option is c. 22.59.

Now moving on to question 33.

The correct answer is a. Both anorexia and bulimia are disorders in which the person is very concerned about his or her body weight. While both disorders involve abnormal attitudes towards weight and food, option b is not entirely accurate as not all individuals with anorexia or bulimia appear thin. It is important to note that each disorder has its distinct characteristics, symptoms, and treatments.

Now let's discuss question 49.

Depressants are especially dangerous because they can have serious effects on the body. However, the correct answer choice is not c. "It causes seizures." The correct answer is a. "At high doses, the user may be at risk for a coma." Depressants, such as alcohol and sedatives, can suppress the central nervous system and lead to respiratory depression, unconsciousness, and even a coma.

I hope this helps!
