Answer:
Yes
Step-by-step explanation:
To see if the Triangle is right use Pythagorean theorem which is A^2+B^2=C^2
A and B are to 10 and 24 because the longest side, the hypotenuse is C
10^2+24^2=676
26^2=676
Therefore the triangle is right
A.) Length= 2w-3 (w=width)
B.) 11=2w-3
First, we add 3 to both sides... And we get
14=2w
Next, we divide by 2 to get the w ( or width) by itself... and the answer would be
7=w... So the width of the rectangle is 7meters
Answer:
87674
Step-by-step explanation:
Order of Operations (PEMDAS)
(2×5)-56+102(4×215)
Do parentheses
(10)-56+102(860)
multiply
10-56+87,720
addition and subtract left to right
-46+87720
87674
Answer:-3/4
Step-by-step explanation:
Get the x by itself by dividing both sides by 8 then reduce -6/8. When you reduce you get -3/4
Answer:
Step-by-step explanation:
Given that at a party there are at least two people.
We have to prove that there are two people who know the same number of other people there
Let n>2 be the no of people there
If possible let us assume each person knows different number of persons
The number of persons any one knows can vary from 0 to n-1
Hence these n people will have 0,1,2....n-1 persons known.
Consider the last person who knows n-1 people this means that he knows everyone in the party. So there cannot be any one who does not know any one or with known persons number as 0.
Thus we get a contradiction.
So there must be atleast two people who know the same number of people
