Question 181772This question is from textbook saxon algebra 2
: A cartographer constructs a map of Georgia over a grid system such that
Macon is at (100, 25) and Atlanta is at (175, 125). Find the distance between
the cities to the nearest kilometer if each unit represents one kilometer.
I worked it out: d=square root (75-100)^2 + (125-25)^2
d=square root (75)^2 + (100)^2
d=square root 5,625+10,000=?
I know the answer is more than just adding the numbers together.

Question 183652: A 25-foot ladder is placed against a building. The bottom of the ladder is 7 feet from the building. If the top of the ladder slips down 4 feet, how many feet will the bottom slide out? (It is not 4 feet).
7 squared+x squared=25 squared
49+x squared=625
x squared=576
x=24
Then what?

Question 186552: Consecutive bases of a square-shaped baseball diamond are 90 feet apart. Find the exact distance from first base diagonally across the diamond to third base. Then approximate this distance.
So far I tried:
90 squared + 90 squared = c squared
8100 + 8100 = c squared
16200 = c squared
when taken by the square root I get
9 square root of 2 = c
approximate distance is 34 feet

Question 189891This question is from textbook Geomerty
: the directions say "Find the value of x. Simplify answers that are radicals." They give me a right triangle and tell me that one of the legs is 5, the hypotonuse is 11 and the altitude is 3. They want me to find the other leg with is labeled x. I didn't think you could find the x unless you knew both of the parts of the hypotenuse?This question is from textbook Geomerty

Question 190258: I also got this one wrong, can someone show me the correct way to solve this, please?
Consider the formula n(A U B) = n(A) + n(B) - n(A ∩ B).
(a) Show that this relation holds for A = {1, 2, 3, 4} and B= {2, 4, 5, 6, 7, 8}
(b) Make up your own two sets A and B, each consisting of at least six elements. Using these two sets, show that the relationship above holds.
(c ) Use a Venn diagram and explain why the relation holds for any two sets A and B.
