Answer:
440
The attached file is how I would have done it.
Answer:
All have same magnitude.
Step-by-step explanation:
Given that
Vector 1 = V+ (-W) = V - W
So the magnitude of vector 1, R₁
R₁ = V -W
For vector 2
Vector 2 = W - V = W - V
So the magnitude of vector 2, R₂
R₂ = V - W
For vector 3
Vector 3 = (-V) - (-W) = - V + W = W - V
So the magnitude of vector 3,
R₃ = W -V
So all have same magnitude.
Answer:
Cheena has 6 pieces of fabric.
Step-by-step explanation:
<em>3/4 yard of fabric also means 6/8 yard of fabric. </em>
(6/8) / (1/8) = 6
Or
6/8 yard = 6 1/8 yard pieces
The correct answer is A. 2.5 meters. One meter has approximately 3 feet, so it would make sense for a car to be about 7.5 feet in length
Hope this helps
Answer:
84 is the highest possible course average
Step-by-step explanation:
Total number of examinations = 5
Average = sum of scores in each examination/total number of examinations
Let the score for the last examination be x.
Average = (66+78+94+83+x)/5 = y
5y = 321+x
x = 5y -321
If y = 6, x = 5×6 -321 =-291.the student cannot score -291
If y = 80, x = 5×80 -321 =79.he can still score higher
If If y = 84, x = 5×84 -321 =99.This would be the highest possible course average after the last examination.
If y= 100
The average cannot be 100 as student cannot score 179(maximum score is 100)
