Answer:
150 pi inches or 471.239 inches traveled
Step-by-step explanation:
First, close your eyes, and think about the distance a bike travels after one rotation of the wheel.
You will come to the realization that a full rotation of the wheel makes you travel the circumference of the wheel
The formula for circumference is 2(pi)(r) or (pi)(diameter)
We are given diameter, so let's find distance traveled for one rotation
pi(15 inches) = 15pi inches per rotation.
There are 10 rotations, so:
(15pi inches/rotation)(10 rotations) = 150pi inches travelled
150 x pi = 471.239 inches traveled
U subtract 4x by 5x and then you add 3 by -21 and the answer is x=18
Answer:
Percentage Profit is 63.63%
Step-by-step explanation:
The man buys 440 eggs at 55 pence a score
i.e. he buys 20 eggs for 55 pence
He buys 1 egg for 55/20 = 2.75 pence
Therefore, he buys 440 eggs for = 440 × 2.75 = 1210 pence
10% eggs are unsaleable
thus he sold = 440 - 440 × 10/100 = 440 - 44 = 396 eggs
Eggs sold in dozen = 396/12 = 33
He sold 1 dozen for = 60 pence
Thus, he sold 33 dozen for = 33 × 60 = 1980 pence
Profit = 1980 - 1210 = 770 pence
% Profit = (770/1210) × 100 = 63.63%
