In triangle XYZ, the length of side XY is 26 mm and the length of side YZ is 37 mm. Which of the following could be the length of side XZ?A. 68 mm B. 44 mm C. 9 mm D. 65 mm
Answers
Answer 1
Answer:
A). 68 D). 65 If the third side was either of these, then (26 + 37) = 63 could not reach between the ends of it. A triangle could not be formed.
C). 9 If the third side was this, then it could not reach between the ends of the 26 and the 37 . . . they're always AT LEAST 11 mm apart.
B). 44 This is the ONLY one on the list that can make a triangle along with 26 and 37.
Answer 2
Answer:
To solve this, you can use the triangle inequality theorem: Side 1 + Side 2 must be greater than Side 3. So, plug in 26 for Side 1 and 37 for Side 2, add them together, and see which number is smaller than 27 + 37.

There are 7 people at a party. If each person shakes the hand of everyone exactly once, how many handshakes will take place
Answers
Call the number of people .
Looking at the first person, they can shake hands with other people (since they can't shake hands with themselves.)
For the second person, they can shake hands with other people. (They can't shake hands with themselves and they already shook with Person 1, on Person 1's turn.
If we carry on this way we see that the total number of shakes is given by: which simplifies to: .
For we then have:
OR
There will be 42 handshakes
There will be 42 handshakes
What is 791=1/2h (26.5+30)
Answers
Following the order of PEMDAS, start with what's inside of the parenthesis, adding 26.5 with 30 ---> 791 = 1/2h(56.5) You need to get h on one side of the equation by itself. To do this, divide the whole equation by .5 (which is the same as 1/2), canceling out the 1/2 on one side of the equation. 791/.5 = 1/2h(56.5)/.5 ----> 1582 = h(56.5) Next, divide the entire equation again by 56.5. 1582/56.5 = h(56.5)/56.5 ---> 28 = h Your final answer is h = 28. To check this, plug 28 into the equation where the value h is.

Math vocab again : the product of a number and its Blank is one
Answers
If you multiply a number and its inverse, you get one. To obtain an inverse, you divide 1 by the number. 0 doesn't have an inverse, because you cannot divide by 0.
Multiply by the reciprocal. (Flip fraction) so the reciprocal of 3 is 1/3 (because 3= 3/1)
