Are you suppose to put it in mixed number form? If so then here are the answers to the last 4 you did answer:
#1 - 2 1/9 (2 Whole and 1 ninth)
#2 - 2 2/10 (2 Whole and 1 tenth)
#3 - 2 3/11 (2 Whole and 3 eleventh)
#4 - 3 (It's just 3 because 4 goes into 12, 3 times)
Answer:
9.21954446 (but round to what ever place is required)
Step-by-step explanation:
Use the Pythagorean theorem
a^2+b^2=c^2
6^2+7^2=c^2
36+49=c^2
85=c^2
c=9.21954446
round to what ever place you need
9514 1404 393
Answer:
-3/5
Step-by-step explanation:
The slope can be found using the formula ...
m = (y2 -y1)/(x2 -x1)
Using the values from the marked points, we have ...
m = (-2 -1)/(2 -(-3)) = -3/5 . . . . it is negative
Add 8 to both sides
5z = 40
divide both sides with 5
z = 8
