Answer:1190
Step-by-step explanation:
Whit the car: 2x70=140
Whit the jet:3x350=1050
140+1050=1190
I think it is the middle one becuase complimentary angles add up to 90 degrees and if one is 8 less than the other it would be proved like that.
Answer:
Step-by-step explanation:
It is hard to guess the coordinates of any points, because the graph doesn't go through any intersections of the grid.
Fortunately, I can tell that the axis of symmetry is x=2.
Put the equation into vertex form by completing the square.
axis of symmetry = b/2
b/2 = 2
b = 4
First, you would add 3/4+3/4 to see how many miles he walks each day. To get this you would simply add the numerators because the denominators are the same. This would get you to 3/4+3/4=6/4 You can then turn this fraction into a mixed number (1 2/4) which can be simplified into 1 1/2. He walks 1 1/2 miles one day and the second day he walks 1 1/2 miles. Add the two days together to get that in 2 days he walks 3 miles.
The final answer is 2 days. I hope I helped :)
Answer:
Sample space is
Step-by-step explanation:
Number of security doors = 3
Let P denote a successful pass and F denote a failed pass.
Sample space refers to a set of all possible outcomes.
If the first attempt to pass through a door is a failure, then the outcome is F.
If the second attempt to pass through a door is a failure, then the outcome is PF.
If the third attempt to pass through a door is a failure, then the outcome is PPF.
If the fourth attempt to pass through a door is a failure, then the outcome is PPP.
