Question 1) x=4
the rest I rly dk
Answer:
d ≈ 87.85 yards
Step-by-step explanation:
The circumference ( C) of a circle is calculated as
C = πd ( d is the diameter ), then
276 = πd ( divide both sides by π )
= d , so
d ≈ 87.85 yards ( to the nearest hundredth )

Answer: 2.79 hours.
Step-by-step explanation:
Given that the function for the learning process is T(x) = 2 + 0.3 1 x , where T(x) is the time, in hours, required to produce the xth unit
To calculate the time for the new worker to produce 10 units, substitute 10 for x in the equation above.
T(x) = 2 + 0.31 (10)
T(x) = 2 + 3.1
T(x) = 5.1 hours
To calculate the time for the new worker to produce 19 units, substitute 19 for x in the equation above.
T(x) = 2 + 0.31(19)
T(x) = 2 + 5.89
T(x) = 7.89 hours
The time required for a new worker to produce units 10 through 19 will be
7.89 - 5.1 = 2.79 hours
