The answer is A) 1/8 or -1/8
So let’s sort out the c:
So 6c - c = 5c
Then let’s sort out the d:
4d + 7d = 11d
So the equation simplified is :
5c + 11d
Answer:
<u>63 km</u>
Step-by-step explanation:
<u>Given</u> :
- Speed = 315 km/h
- Time = 12 minutes
<u>Solving</u> :
<u>Convert minutes into hours so that the units are </u><u>equal</u><u>, otherwise your answer will not be correct.</u>
- There are 60 minutes in an hour
- Therefore, 12 minutes is equal to :
- 12/60 hours
- 1/5 hours
- 0.2 hours
<u>Calculating distance</u>
- Distance = Speed x Time
- Distance = 315 km/h x 0.2 h
- Distance = <u>63 km</u>

Answer:
Area segment = 3/2 π - (9/4)√3 units²
Step-by-step explanation:
∵ The hexagon is regular, then it is formed by 6 equilateral Δ
∵ Area segment = area sector - area Δ
∵ Area sector = (Ф/360) × πr²
∵ Ф = 60° ⇒ central angle of the sector
∵ r = 3
∴ Area sector = (60/360) × (3)² × π = 3/2 π
∵ Area equilateral Δ = 1/4 s²√3
∵ The length of the side of the Δ = 3
∴ Area Δ = 1/4 × (3)² √3 = (9/4)√3
∴ Area segment = 3/2 π - (9/4)√3 units²
