Answer:
The minimum amount of breaking strain the crane can handle is 6350 kg. (Since it is measured to 2 sig. figs, 6349 kg would round down to 6300 kg, hence the min. is 6350 kg.)
The maximum weight of each crate would be 94 kg. (Since it is measured to the nearest 10 kg, 95 kg would round up to 100 kg, hence the max. is 94 kg.)
Therefore, the greatest number of crates that can be safely lifted would be (6350/94) crates which is 67.5 crates, which rounded down is 67 crates.
All numbers are taken as integers in this answer.

Answer:
The expression for the total amount of Jamal earned is $ (14 y + 55)
Step-by-step explanation:
Given as :
The bonus amount earn by Jamal = $ 55
According to question
On Thursday
∵ For 1 hour of work , Jamal earn y dollars
∴ For 9 hours of work , Jamal will earn 9 × y = 9 y dollars
On Friday
∵ For 1 hour of work , Jamal earn y dollars
∴ For 5 hours of work , Jamal will earn 5 × y = 5 y dollars
So, The total earning on both days of his work = 9 y + 5 y = 14 y dollars
Since Jamal also earn bonus of $ 55
So, Total earning of Jamal including bonus = 14 y + $ 55
Hence The expression for the total amount of Jamal earned is $ (14 y + 55) Answer

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
