Question

1. madagascar hissing cockroaches are very unusual creatures. they are very large and make strange hissing noises that may be part of an elaborate mating behavior. they grow to be 75 cm in length and may weigh 227 grams. a small colony of these cockroaches can eat a large carrot in a single day.

a. how long is the cockroach in inches? ________
b. how many ounces does the cockroach weigh? ________

1. whale sharks are the largest fish in the sea. they are sharks but are considered to be \gentle giants.\ being filter - filters, they swim with their mouths open wide, collecting plankton and small fish. they may grow to be 32.8 feet in length and may weigh in at an enormous 41,200 pounds.

a. how long is the whale shark in meters? ________
b. what is the mass of the whale shark in kilograms? ________

1. the cheetah is the worlds fastest land animal. amazingly, it can reach speeds of 96 kilometers per hour in only three seconds.

Explanation:

Step1: Recall length conversion factor

1 inch = 2.54 cm. To convert 75 cm to inches for the cockroach, use the formula $length_{inches}=\frac{length_{cm}}{2.54}$.
So, $length_{inches}=\frac{75}{2.54}\approx29.53$ inches.

Step2: Recall mass - weight conversion factor

1 ounce = 28.35 grams. To convert 227 grams to ounces for the cockroach, use the formula $weight_{ounces}=\frac{weight_{grams}}{28.35}$.
So, $weight_{ounces}=\frac{227}{28.35}\approx8.01$ ounces.

Step3: Recall length conversion factor for whale - shark

1 foot = 0.3048 meters. To convert 32.8 feet to meters for the whale - shark, use the formula $length_{meters}=length_{feet}\times0.3048$.
So, $length_{meters}=32.8\times0.3048 = 10$ meters.

Step4: Recall mass - weight conversion factor for whale - shark

1 pound = 0.453592 kilograms. To convert 41200 pounds to kilograms for the whale - shark, use the formula $mass_{kilograms}=mass_{pounds}\times0.453592$.
So, $mass_{kilograms}=41200\times0.453592\approx18788$ kilograms.

Answer:

a. The cockroach is approximately 29.53 inches long.
b. The cockroach weighs approximately 8.01 ounces.
a. The whale - shark is 10 meters long.
b. The mass of the whale - shark is approximately 18788 kilograms.
