The four-chambered heart of a humpback whale weighs approximately 430 pounds. 1 kilogram is equal to 2.2 pounds. What is the wei

Bezzdna [24]

Answer:

B. 195.5 kg

Step-by-step explanation:

Given

Weight in pounds = 430 pounds

1 kilogram = 2.2 pounds

Required

The weight in kilogram

Let x represents the weight of the humpback's whale's heart in kilogram

Such that;

$x = 430 lb$

$1kg = 2.2lb$

By Cross multiplication

$x * 2.2lb = 430lb * 1kg$

Divide both sides by 2.2lb

$\frac{x * 2.2lb}{2.2lb} = \frac{430lb * 1kg}{2.2lb}$

$x = \frac{430lb * 1kg}{2.2lb}$

$x = \frac{430lb1kg}{2.2lb}$

$x = \frac{4301kg}{2.2}$

$x = 195.454545 kg$

Approximate

$x = 195.5kg$

Hence, the weight of the heart is 195.5kg
