Twins Lidia and Henry collected snow globes. When they left for college, they split the collection, such that Lidia got 75% of the snow globes. If Lidia got 460 more snow globes than did Henry, how many snow globes did Henry get?

230

Step-by-step explanation:

Okay, so if Lidia got 75% means that Henry got 25%, right?

Then Lidia got 50% more than Henry did. So that 460 = 50%

So Henry got 25% which is 460/2 = 230 snow globes

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

-320.44 is the maximum temperature at which nitrogen is a liquid.

-346 is the minimum temperature at which nitrogen is a liquid.
