Number of people can hold in each car = 10
Solution:
Number of cars in the Blazing Bullet = 6
Total number of people can ride at one time = 60
Number of people can hold at one Bullet car = ?
Let n be the number of people in each car can hold.
Now write a equation to find the number of people in each car.
Number of cars × number of people in each car = Total number of people
⇒ 6 × n = 60
⇒ 6n = 60
Now, solving this equation.
⇒ 6n = 60
Divide both sides of the equation by 6.
⇒ n = 10
Hence 10 people can hold in each car.
Answer: 57°
Given : In triangle PQR, the side PQ is 17, QR is 15, and PR is 14.
We use law of cosine formula
225 = 196 + 289 - 476 cos(P)
225 = 485 - 476 cos (P)
Subtract 485 on both sides
-260 = -476 cos(P)
= cos(P)
P =
P= 56.89202
So measure of angle P is 57 degrees
