Step-by-step explanation:
Just follow these steps!
Non-zero digits are always significant.
Any zeros between two significant digits are significant.
A final zero or trailing zeros in the decimal portion ONLY are significant.
Answer:
Ned lost 16 points total.
Step-by-step explanation:
If Ned got 6 questions wrong, and each one cost him four points, that would be 24 points total. 6x4=24. But since Ned got 8 additional points on a bonus question. It equals out to a total los of 18 points.
-24 + 8= -16
consider X-axis along the east-west direction and north-south direction along Y-axis
A = magnitude of distance traveled by hiker in north-east direction = 30 kilometer
θ = angle of direction of displacement of the hiker relative to x-axis or east direction = 45 degree counterclockwise
A' = component of distance traveled by the hiker along the east direction.
Since the angle is given with the x-axis, the Sin provides the component in Y-direction. hence
Using the equation
A' = A Sinθ
Inserting the values
A' = (30) Sin45
A' = 21.2 km
Answer:
The operation that will cancel out division is multiplication.
Step-by-step explanation:
For example:
*in order to solve for x, and get the upper equation without division, you must multiply by the negative reciprocal*
*to get x alone, we must subtract 4 from both sides*
