The mass of a large adult male hippo is about 1,850,000 grams and the mass of a large adult female is about 1,525,000 grams. what is the difference, in kilograms, between the masses of the adult male and female hippos

325 Kg is the difference in masses of the hippos.

Step-by-step explanation:

Mass of the large adult male hippo is about 1850000 grams.

Since 1000 grams = 1 Kilograms

So weight of the large adult male hippo will be = = 1850 Kg

Similarly mass of adult female hippo = 1525000 grams

mass in Kilograms =

Now difference in their masses = 1850 - 1525 = 325 Kg

Therefore, difference between the masses of male and female hippos is 325 Kg.

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
