Answer:
a) A = {-3, -2, -1}
b) n(A) = 3
c) A is finite
Step-by-step explanation:
a) The elements of A are the integers between -4 and 0, not including those values. Those integers are -3, -2, -1, so those are the elements of set A.
A = {-3, -2, -1}
__
b) n(A) is the number of elements in set A. Obviously, there are 3:
n(A) = 3
__
c) Since n(A) is not "infinity", the set A is finite.
Answer:
Step-by-step explanation:
"one half the sum of a number and 4" is (1/2)(n + 4)
"three less than the quotient of 5 and the number" is 5/n - 3
putting this all together, we get
(1/2)(n + 4) = (5/n) - 3
Answer:
4.91666666667
Step-by-step explanation:
1 1/3 + 1 5/6 + 1 3/4 = 4.91666666667
You can find the improper fractions of both.
14 1/2=29/2
1 3/5=8/5
Divide the two numbers
(29/2)/(8/5) and you will get 145/16 or 9.0625.
Therefore, you can fit 9 books on the bookshelf.
The answer is reduction. This can be found by the size and number differences in the two quadrilaterals.
