Answer:
Step-by-step explanation:
P= {1,3,5,7,9,11,13,21}
R ={2,4,6,8,10,12}
O={3,6,9,12,15,18}
The union of two sets contain all the elements in either set.
R ∪ O = {2,4,6,8,10,12,3,9,15,18 } [6 & 12 are in both R and O. we have to write only one time]
P U (R ∪ O) = {1,3,5,7,9,11,13,21,2,4,6,8,10,12,15,18}
Answer:
1,360 beats when she is resting
Step-by-step explanation:
17 times per 15 seconds in a 20 minute span
how many 15 seconds are in 60 seconds.
There is 4 periods of 15 minutes in one minute
17 * 4 = 68
68 * 20 = 1360
I think that is correct
Decrease because the arrow is pointing down
Because 5x4 is 20 but 5x1/4 is 1,25.
5 x 1 = 5... / 4 = 1,25
Or ... -> 1/4 = 0,25 * 5 = 1,25

I was stuck on the same thing in my class test. I ended up failing but if I get the answers to it I’ll totally send them to you!!!
