Answer:
Step-by-step explanation:
Angle BOA = length of arc/radius
=8.4/8
= 1.05 radians
= 1.05*180/pi
= 60.16°
= 60°
Angle AOC = 45°
Angle BAC = 60.16 + 45
= 105.16°
Arc BAC = radius * angle (degrees) * pi /180
= 8 × 105.16 × (3.14159/180)
= 14.683 cm
= 14.7 cm
The cost of the milk is in 1950s.
Further explanation:
The price of milk in 2013 was around a gallon.
And it is given that this was eight times as much as one can would have probably paid for a gallon of milk in the 1950s.
It is given that the price of milk in 2013 is a gallon.
Assume the price of milk in 1950 be a gallon.
Now, given that 8 times of is the price of milk in 2013.
Therefore, is the price of milk in 2013 and also
is the price of milk in 2013.
Equating and
equal as both are the price of milk in 2013 as,
Here, x is the price of milk in 1950.
Therefore, the cost of the milk is in 1950s.
