Answer:
60 seconds
Step-by-step explanation:
Hi!
After she goes forward 5 feet (4 seconds), and the backwards 3 feet (another 4 seconds), the total distance forward she travelled is 2 feet. Then, she moved forward 2 feet in 8 seconds.
Then, as this is repeated, she moves forward 2 feet every 8 seconds. After 7 repetitions she travelled 14 feet, and 56 seconds elapsed. Then she goes forward 5 feet in 4 seconds, and she finaly reaches the end of the hallway
(14 +5 > 15)
So, in 60 seconds she reached the end of the hallway.
Answer:
The answer to your question is: 48.6 ft
Step-by-step explanation:
See the picture below
Use the Thales's theorem to solve this exercise
x / 27 = 45 / 25
x = 45(27) / 25
x = 1215 / 25
x = 48.6 ft
42 = 40(x-1) + 40
x-1 will be equal to the sales tax rate in this equation.
Answer:
a) The subset consists of all the outcomes where your friend loses or there is a tie.
d) The subset consists of all the outcomes where you do not lose.
Both are correct.
Step-by-step explanation:
The subset A= { 1,3,4,6,7,9} removes 2,5 and 8 from the sample space of the game. Those three numbers are the ones for which your friend wins, therefore, the subset consists of all outcomes for which you either win (your friend loses) or there is a tie.
Checking the given alternatives, there are actually two correct ones. Alternatives a) and d) describe the same sample space (you not losing = your friend not winning).
Therefore, the two possible answers are:
a) The subset consists of all the outcomes where your friend loses or there is a tie.
d) The subset consists of all the outcomes where you do not lose.
The answer is 10 so good job
