Answer:
22.5 newtons
Step-by-step explanation:
the vertical Component of force = Fv,
Fv = F. sin 65°
= 25 . (0.9)
= 22.5 newtons
He will need 6 tenth size strips because if you put 3/5 vertically with another fraction beside of it that had the numerator blank and the bottom 10. You do this because Jeff uses fifth size strips so 5 represents the strips and you need tenth size strips so you find our numerator for the tenth size strips. You find out how many times 5 can go into 10 or 5 times what equals 10 and it's 2. So whatever you do to the bottom you do to the top. You times 5 by 2 at the bottom and get 10 for the tenth size strips and 3 times 2 at the top yoi get 6 and that is 6/10 is your answer
The total number of people that all the cars can hold is greater than 480 and less than 500 people.
A: According to the given situation, where both the number of trolley cars and the number of people in each car must have two digits and be less than 30.
Hence, the possible number of trolley cars in the park = 22 and a possible number of people in each car= 22
B: explain how you found your answer.
Lets suppose the number of cars be =c and the number of persons be= p
As the number of cars and number of person are same, so c=p
so,
should lie the given range of 480 to 500.
Now, the nearest perfect square that lies between 480 and 500 is 484.
The square root of 484 is 22. So, the number of cars and people are 22.
C: This is the only hit and trial method for solving this question.
