Okay so...
There are 21 groups of 3.
21 x 3 = 63.
63 people are in the room.
Short answer: No and yes.
Yes First.
If the lower right point (looks like an C perhaps or an F) and the middle point and the upper left point lie on the same line and if D the middle point and the upper right point lie n the the same line, then yes. You have angle side angle. The lower right angle is given as equal to the upper left angle. The angles at C are vertically opposite angles and they are equal and you have been given 2 enclosed sides that are equal.
No
If the points I've described are not on the same line, then the triangles are not congruent. If I can, I'll edit this a second time.
Please Note:
You have done something that looks a bit illegal to me. I wouldn't just trade pictures. It only costs you another 5 points to issue another question. I do think, however, that it is very clever. In answering about 1700 questions, I've never seen this done. That's commendable.
Answer:
#1. 105.5 because of the nine 4 goes to 5
#2. 67,990,000 because of the 4 it doesn't go up
#3. -4.1 because of the 4 the 0 goes to 1
if the number place before the one you are rounding is 5,6,7,8,or 9you go up by one and the rest becomes zeros
if the number place before the one you are rounding is 0,1,2,3,or 4 you stay the same and the rest becomes zeros
9514 1404 393
Answer:
Step-by-step explanation:
In the English expression, you need to understand that "A divided by B" means that A is the numerator and B is the denominator of the fraction representing the division. Here, "B" is "the quantity of ...", which means that the stuff after "of ..." is to be treated as a single item, the denominator in this case. That item is "x plus y." So, the expression in math terms is ...
When this is written in plain text, the "quantity" is put in parentheses, because the fraction bar no longer serves as a grouping symbol:
9/(x+y)
These expressions match the first choice, A.
