Answer:
The correct answer is 20 questions she took some off.
Step-by-step explanation:
The operation indicated, A - B, is a subtraction of sets.
The subtraction of set B from set A means that you have to remove the elements of B that are on A; i.e. A - B = {15, 35, 55}
25, 45 and 65 (which are in the set B) were removed from the set A to form the set A - B
397.19333 because is you divide 1,143.75 into 75 groups you would get 15.2766667 and you multiply that by 26
Answer:
40 people who don't like any of the three drinks.
Step-by-step explanation:
It is given there are 340 people in total
Number of people like tea=150
Number of people like tea only =90
Number of people like coffee only =80
Number of people like milk only =70
Number of people like coffee and milk only = 0
We can draw Venn diagram which helps us to find the number of people who don't like any of these three drinks. I'll attach the file.
Answer: x equals 9
Step-by-step explanation: The figure in the question is a Rhombus and one of the properties of a rhombus states that “the diagonals bisect each other.”
This means line SU bisects line TV into two equal parts at point W. This also means that line WV is half of line TV. If line TV equals 74 and line WV equals 4x + 1, then we have the following;
(4x + 1) x 2 = 74
4x + 1 = 74/2
4x + 1 = 37
Subtract 1 from both sides of the equation
4x = 36
Divide both sides of the equation by 4
x = 9.
