Answer:
the triangle formed from the coords is 3cm by 9cm so try 3 × 9 = 27 then 27 ÷ 2 = 13.5 from the formula a = ½bh?
Step-by-step explanation:
This is how you find the mean of a number:
To find the mean of a number, you need to add up all the numbers listed (so, 5, -11, 7, 12, -1 and 0) and then divide it by the amount of numbers there are listed. 5 + -11 + 7 + 12 + -1 + 0 equals 12, and since there are 6 numbers you then divide 12 by 6. 12 divided 6 is 2.
So the answer is A. I hope this helped you!
You could do 3 ten dollar bills, 5 six dollar bills, two fifteen dollar bills and probably a few more. If you had $45 you could use 8 five dollar bills, 8 five dollar bills
**Remember this rule: the sum of a triangle's angle measurements always = 180
So 2x + 3x + 4x = 180
9x = 180
9x/9 = 180/9
x = 20
A) 20
