Radius of a wheel = 13 inch
= 1.08333 ft
circumference of a wheel = 2×pi×r^2
= 2 × (22/7) × 1.08333^2 ft
= 2 × (22/7) × 1.1736 ft
= (44/7)×1.1736 ft
= 51.6384/7 ft
= 7.3769142857 ft
distance covered in one minute = 37 × 60 ft/min
= 2220 ft/min
now, revolution per minute = 2220 / 7.3769142857
= 300.93884
therefore her wheels are making 300.93884 revolutions per minute
The correct answer would be 9
Answer:
The cost of each Hand towels is $5 and Cost of each Bath towel is $11.

So we can say that;
⇒ Equation 1
Also Given:
99 hand towels and 62 bath towels for his hotel in Lancaster, spending $1,177.
So we can say that;
⇒ Equation 2
Substituting the value of 'x' from equation 1 in Equation 2 we get;

Now taking LCM to make the denominator common we get;


Combining the like terms we get;

Dividing both side by 1109 we get;

Substituting the value of y in equation 1 we get;

Hence The cost of each Hand towels is $5 and Cost of each Bath towel is $11.
