Answer:worked 7 hours
Step-by-step explanation:
93 - 65 = 28
28/4 = 7 hours
the number of elements in the union of the A sets is:5(30)−rAwhere r is the number of repeats.Likewise the number of elements in the B sets is:3n−rB
Each element in the union (in S) is repeated 10 times in A, which means if x was the real number of elements in A (not counting repeats) then 9 out of those 10 should be thrown away, or 9x. Likewise on the B side, 8x of those elements should be thrown away. so now we have:150−9x=3n−8x⟺150−x=3n⟺50−x3=n
Now, to figure out what x is, we need to use the fact that the union of a group of sets contains every member of each set. if every element in S is repeated 10 times, that means every element in the union of the A's is repeated 10 times. This means that:150 /10=15is the number of elements in the the A's without repeats counted (same for the Bs as well).So now we have:50−15 /3=n⟺n=45
21 because you have to have at least 1 side as 3m so the other two should be 9m to have the greatest possible length
Betina is 155 centimeters tall or 1 meter and 55 centimeters
1 meter = 100 centimeters
100 + 87 = 187 , Brian’s height in centimeters
Since Bonnie is 58 centimeters shorter we will subtract 187-58 which gives us 129 centimeters.
Betina is 26 centimeters taller than Bonnie so we add 26+129 =155
Therefore Betina is 155 centimeters tall or 1 meter and 55 centimeters.
Hope this helped! :)
