The equation for the distance is:

(a/60) × 8 mi/min + (b/60) × 7.5 mi/min = D

We know that she runs 45 minutes each day, such that she runs at a rate of 8 miles per hour for a minutes, and then runs at 7.5 miles per hour for b minutes.

Now, remember the relation:

speed × time = distance.

Because a and b are in minutes, we need to rewrite the speed in minutes, remember that there are 60 minutes in one hour, then:

8 mi/h = (1/60) × 8mi/min

7.5 mi/h = (1/60) × 7.5 mi/min

Then the equation for the distance is:

a × (1/60) × 8 mi/min + b × (1/60) × 7.5 mi/min = D

(a/60) × 8 mi/min + (b/60) × 7.5 mi/min = D

Answer:

See explanation

Explanation:

When an element tends to lose its valence electrons in chemical reactions, it behaves more like a metal.

When an element tends to gain valence electrons in chemical reactions, it behaves more like a nonmetal.

Metalloids have properties intermediate between those of pure metals and pure nonmetals. Usually, metalloids appear in groups where they are sandwiched between nonmetals and metals such as in groups 13, 14 and 15.

<h3>What is the duty of the Nurse?</h3>

The action that the nurse who is caring for a client who is in the transition phase of labor should take is; C. Assist the client with patterned-paced breathing.

The reason is that Patterned breathing refers to the act of breathing at any number of possible rates and depths. Some women prefer breathing deeply, using their diaphragm to fill their abdomen with air. Other women prefer light breathing, inhaling just enough to fill their chest. The goal is to find breathing patterns that have a calming and relaxing effect.

The benefits of patterned breathing are;

  • Breathing becomes an automatic response to pain
  • The mother remains in a more relaxed state and will respond more positively to the onset of pain
  • The steady rhythm of breathing is calming during labor
  • Provides a sense of well being and control
  • Increased oxygen provides more strength and energy for both the mother and baby
  • Brings purpose to each contraction, making contractions more productive

The missing options are;

A. Instruct the client to use effleurage

B. Apply counter pressure to the client sacral.

C. Assist the client with patterned-paced breathing.

D. Teach the client the technique of biofeedback
