Ahemoglobin test measures 14.5 grams of hgb per 100 ml of blood if the patient has 5.5 quarts of blood in her body, how many grams of hgb are present?

Quantity of Hgb in 100 ml of blood = 14.5 grams

Now we will use unitary method to find quantity of Hgb in 1 ml of blood.

Quantity of Hgb in 1 ml of blood = 14.5 /100 = 0.145 grams.

Now we have to find quantity of Hgb in 5.5 quarts of blood.

Let us first convert 5.5 quarts into ml.

1 quart = 946 ml

So 5.5 quarts = 5203 ml

So quantity of Hgb in 5203 ml of blood = 0.145 * 5203 = 754.435 grams

The patient has 754.435 grams of Hgb in his body.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
