Which statement about numbers is true? All whole numbers are rational numbers. All rational numbers are integers. All rational numbers are whole numbers. All integers are whole numbers.

I think that the answer is B “All rational numbers are integers.”

I don’t know if this is correct so please double check.

Hope I helped!

step-by-step explanation:

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
