ELEN [110]

Answer:

Total 495 liters of natural oil are needed.

Explanation:

It is given that Petrolyn motor oil is a combination of natural oil and synthetic oil. It contains 5 liters of natural oil for every 3 liters of synthetic oil.

It means the ratio of natural oil and synthetic oil is

\frac{\text{Natural oil}}{\text{Petrolyn motor oil}}=\frac{5}{5+3}=\frac{5}{8}

Let in order to make 792 liters of Petrolyn oil he needs x liters of natural oil.

It means the ratio of natural oil and synthetic oil is

\frac{\text{Natural oil}}{\text{Petrolyn motor oil}}=\frac{x}{792}

Equate both ratios,

\frac{x}{792}=\frac{5}{8}

On cross multiplication we get

8\times x=5\times 792

8x=3960

Divide both sides by 8.

x=\frac{3960}{8}

x=495

Therefore total 495 liters of natural oil are needed.

Which component of the electrocardiogram represents the duration of ventricular contraction?
Advocard [28]

QRS complex refers to the combination of the Q, R, and S waves, and indicates ventricular depolarization and contraction (ventricular systole).

Ventricular rate can be calculated by determining the time interval between QRS complexes. The duration of the QRS complex is normally 0.06 to 0.10 seconds. This relatively short duration indicates that ventricular depolarization normally occurs very rapidly.

P QRS and T waves in electrocardiogram signifies the P wave in an ECG complex indicates atrial depolarization. The QRS is responsible for ventricular depolarization and the T wave is ventricular repolarization.
