Answer:
The percent difference is the absolute value of the difference over the mean times 100. quantity, T, which is considered the “correct” value. The percent error is the absolute value of the difference divided by the “correct” value times 100.
Step-by-step explanation:
Answer:
x=6
Step-by-step explanation:
9(8-x)=3x
9 x 8=72
72-9x=3x
72=12x
72/12=6
x=6
7 because 7x3= 21 and 21 + the 7 cats comes to an equal 28
Distance formula : sqrt ((x2 - x1)^2 + (y2 - y1)^2
1.) (-4,0).....x1 = -4 and y1 = 0
(4,6)......x2 = 4 and y2 = 6
now sub into the formula...
d = sqrt ((4 - (-4)^2 + (6 - 0)^2)
d = sqrt ((4 + 4)^2 + (6^2))
d = sqrt (8^2 + 6^2)
d = sqrt (64 + 36)
d = sqrt 100
d = 10 <=====
u would use the exact same formula for the rest of these problems
2.) (5,7),(0,-5)......distance is : 13
3.) (2,-1),(1,-4).....distance is : 3.16
4.) (-7,-2),(0,7).....distance = 11.4
Answer:
29.98
Step-by-step explanation:
You subtract the 69 from the 40.02 and ypu get 29.98
