The ordered pair (2,7), is not a solution to the equation
Answer:
D. The figure is not necessarily a parallelogram because only one diagonal is bisected and only one pair of sides is congruent
Step-by-step explanation:
<em>The parallelogram has the following properties:</em>
- <em>Opposite sides are parallel by definition.</em>
- <em>Opposite sides are congruent.</em>
- <em>Opposite angles are congruent.</em>
- <em>Consecutive angles are supplementary.</em>
- <em>The diagonals bisect each other.</em>
A. The figure is a parallelogram because there are two pairs of congruent sides.
- no
B. The figure is a parallelogram because a diagonal is bisected.
- no
C. The figure is not necessarily a parallelogram because the diagonals are not congruent.
-no
D. The figure is not necessarily a parallelogram because only one diagonal is bisected and only one pair of sides is congruent.
-yes
Alright, lets get started.
Suppose previously I was selling product per week = x
As per question, I have decreased my average number of product by 15 %
Means I have decreased number of product by : x * 15 % = x * 0.15 = 0.15 x
So, the new average product = x - 0.15 x = 0.85 x
As per given question, the new average product = 21.25
0.85 x = 21.25
Dividing by 0.85 in both sides
0.85 x / 0.85 = 21.25 / 0.85
x = 25
Hence it means, 25 products were selling previuosly. : Answer
Hope it will work :)
300. if you sold a third. then 2/3 would be left. you can then infer each is 300. Hope This Helps.
Since there are 10 persons in the group who do not know one another, the real number of handshakes will be 45.
<h3>What is combination?</h3>
In probability theory and other branches of mathematics, the term "combination" refers to a succession of results where the order is irrelevant. A combination is a selection of all or a portion of a group of items, regardless of the sequence in which the items are chosen. Combinations and permutations may appear to be synonyms. However, they are defined differently in probability theory. Combinations: The sequence of results is irrelevant. Permutations: The sequence of events matters.
Here,
Total number of handshakes = 10C2 = (10 × 9)/2 = 45 handshakes.
When 10 people are shaking hands, each one will shake hands with 9 others.
The total number of handshakes in actual = 90/2 = 45 handshakes.
The total number of handshakes in actual will be 45 handshakes as there are 10 people in the group who do not know each other.
