Answer:
It will be less than 2 hours because in total that would be an hour and 30 minutes.
Step-by-step explanation:
We know it takes 18 minutes for him to walk to school, and we also know there is 5 days of a school week, so 18x5= 90 minutes, which equals to an hour and 30 minutes, less than 2 hours in one week.
Answer: 1,509.52 meters
Step-by-step explanation:
Hi, since the situation forms a right triangle (see attachment) we have to apply the next trigonometric function.
Tan α = opposite side / adjacent side
Where α is the angle of depression from one mountain to another, the opposite side is the difference between heights, and the adjacent side (x) is the horizontal distance between the two summits.
Replacing with the values given:
Tan 15.9 = 430/x
Solving for x:
x = 430/ (tan 15.9)
x= 1,509.52 meters

Answer: C) twelve over fifty one
Step-by-step explanation:
Formula for probability =
We know that , a standard deck has 52 cards.
Number of hearts = 13
If a heart was drawn on the first draw and not replaced, then the number of hearts left = 13-1=12 (favorable outcomes)
The total number of cards left = 52-1=51 (total outcomes)
Therefore, the probability of drawing a heart from a standard deck of cards on a second draw, given that a heart was drawn on the first draw and not replaced would be :-
Hence, the correct answer is option C) twelve over fifty one
