Answer:
y=15
Step-by-step explanation:
Because of the exterior angle theorem angle A plus angle b or equal to 146.
so you set 5y+3+4y+8=146 and solve
5y+3+4y+8=146
9y+11=146
9y=135
y=15
Answer: circumference = 2Πr²
Where r= 3
Π=3.14
Therefore Circumference = 2×3.14× 3²
= 2×28.26
Circumference=56.52
Formula:
Subtitute in 3 for r.
Solve and the answer is 28.26
Answer:
Distance in meters D = 167.75 meters
Step-by-step explanation:
Distance covered in 5 seconds is given by:
Distance, D = Speed (S) X Time (T)
Where,
Distance = ?
Speed = 75mph
Time = 5s
Since we are calculating distance in meters, we have to convert 75miles per hour to meters per second
75mph = 75miles/1hr X 1km/0.621miles X 1000m/1km X 1hr/60mins X 1min/60s
= (75X1000) / (0.621X60X60) meter per second
= 75000/2235.6 meter per second
= 33.55 meter per second
∴ Distance D = 33.55 meter per second X 5 seconds
= 167.75 meters
Answer:
Step-by-step explanation:
