Answer:
the center: (-3; 2)
the radius: √65
the equation of the circle: (x + 3)² + (y - 2)² = 65
Hey!
You must divide the amount of money he spent by the amount of money each ticket costs:
32 ÷ 8 = 4
So, Mr. Chen bought 4 tickets.
Step-by-step explanation:
The car travels 600 feet in 20 seconds
=> 30 feet per second
The moyorcycle travels 300 feet in 12 seconds
=> 25 feet per second
Since 30 > 25, the car travels faster than the motorcycle.
Answer:
1- 51.496yd 2- 39.25ft 3- 163.28cm 4- 53.38mm 5- 50.24in 6-94.2ft 7-18.84yd 8- 207.24m
Step-by-step explanation:
So how you do circumference is you find the diameter and times it by pi.
for 1. you will do 8.2 times 2 for the diameter then times it by pi and get 51.496 yards.
for 2 you would do 12.5 times pi and get 39.25ft
for 3 you would do 26 times 2 which is 52 then multiply it by pi which is 163.28cm
for 4 you do 17 times pi which is 53.38mm
for 5 you do 16 times pi which is 50.24in
for 6 you do 30 times pi which is 94.2ft
for 7 you do 3 times 2 which is 6 then multiply by pi which is 18.84yd
for 8 you do 33 times 2 which is 66 then multiply by pi which is 207.24m.
