Answer:
10.
8.
Step-by-step explanation:
10. each step is 36, so i added it twice to get 72.
then add 16 twice = 32
this gives us two sides to our triangle.
We can now use tan since we know opp and adj
tan 32/72 = .44
arctan = 23.75
8. since we again know the opposite and adjacent sides to the angle e are trying to find we can use tan again.
tan 12.5/18 = .694
arctan= 34.76
In one year, the Perseid meteor shower had a meteor appear every 1 1/5 minutes on average. That same year, the Leonid meteor shower had a meteor appear every 4 2/3 minutes on average. How many more meteors fell during the Perseid meteor shower?
Answer:
325,452 meteors
Step-by-step explanation:
We all know that :
We have 365 days in a year and in each day there are 24 hours, Likewise an hour has 60 minutes
SO, the total number of minutes in a year is :
365 × 24 × 60 = 525600 minutes
For Perseid meteor:
So one meteor fall at 1.2 minutes interval Thus, in a year, we will have :
1 meteor - 1.2 minutes.
x meteor - 525600 minutes.
1.2x = 525600
x = 438000
∴ 438,000 meteors fell during the Perseid shower.
For Leonid meteor shower:
So one meteor fall at 4.67 minutes interval Thus, in a year, we will have :
1 meteor - 4.67 minutes.
x meteors - 525600 minutes.
x = 112548
112,548 meteors fell during the Leonid Shower.
Finally , the numbers of more meteors that fell during the Perseid meteor shower is calculated by the difference in the number of Perseid meteor shower and Lenoid meteor shower. i.e
438,000 - 112,548 = 325,452
325,452 more meteors fell during the Perseid meteor shower
