Answer: 2.) 301 miles (3) 30 minutes
Explanation:
2)
Distance traveled per gallon of petrol = 43 miles
Distance traveled on 7 gallons ;
43 × 7 = 301 miles
3)
time taken to cover distance = 45minutes = 45 / 60 = 0.75 hour
Speed of travel = 80km/hr
Recall:
Distance = Speed × time
Distance = 80km/hr × 0.75hr = 60km
Therefore, time required to cover the same distance at 120km/hr equals :
Time = distance / speed
Time = 60km / 120km/hr = 0.5 hr
= 0.5 × 60 = 30 minutes
The answers are letters B and D. They are not soluble in water and the hydrogen-oxygen ratio is different. Good luck!
Answer: perform standard CPR
Explanation:
The Heimlich maneuver is a type of abdominal thrusting typically applied when a victim is showing signs of choking. However, during the rescue attempt the victim may become unconscious; in this case, standard cardiopulmonary resuscitation (CPR) is performed accompanied by chest compressions and rescue breaths.
Before beginning CPR, the rescuer should call their official emergency hotline and attempt to find the foreign object causing the obstruction. If located the rescuer should try to reach for and dislodge it if possible- if it can't be removed, then CPR may be initiated.
The rescuer should perform 30 chest compressions to restore circulation, open the victims airway via the head-tilt, chin-lift maneuver and provide 2 rescue breaths through performing mouth-to-mouth or mouth-to-nose breathing per cycle; this should be continued until the victim rouses or emergency personnel is able to take over.
