Ron has enough time to finish his homework and walk the dog before his lesson. Ron should overestimate the total time needed. Since Ron has 50 minutes to spare he could add 25 to home work time and another 25 to walking his dog. he still ha time to do both.
Multiply the cost, 120, by 0.07
you will get 8.4
Janet will pay $8.40 in sales tax
To calculate for the magnitude of vector PQ, what needs to be done is to determine the distance between them through the two-point equation which is shown below.
d = sqrt ((x₂ - x₁)² + (y₂ - y₁)²)
Substituting the known values,
d = sqrt ((13 - 5)² + (12 - 9)²)
The value of d from the equation is sqrt of 73 or 8.54.
Therefore, the magnitude of the vector is equal to 8.54.
The answer should be the SAS postulate
