Answer:
The answer is B. 14.7%.
Step-by-step explanation:
Given:
Estimated time need to complete project 
.
Actually time needed 
=
h.
Difference between the time 
= 
.
So, the percentage error is 
.
Therefore, the answer is B. 14.7%.
Shouldn't your question be "How many minutes does it take to travel one mile"?
There are 60 minutes in an hour so 45 mph =
45 / 60 = .75 miles per minute
If we take the reciprocal we will get minutes per mile:
1 / .75 miles per minute = 1.3333333333 minutes per mile, so it will take 1.33333333 minutes.
(y2-y1)/(x2-x1)
(6-1)/(-6- -3)= 5/-3
slope= -5/3
y=-5/3x + b
6=-5/3(-6)+b
b or the y-int= -4
therefore the equation is y=-5/3x -4
Answer:
3x(2x - 3)(2x + 3)(5x - 1).
Step-by-step explanation:
60x4 − 12x3 − 135x2 + 27x
= 3x(20x^3 - 4x^2 - 45x + 9) We can factor what's in the parentheses by grouping:
= 3x(4x^2( 5x - 1) - 9(5x - 1))
= 3x (4x^2 - 9)(5x - 1) Now we factors 4x^2 - 9:
= 3x(2x - 3)(2x + 3)(5x - 1).
The answer is 165.6 hope this helps
