Answer:
Step-by-step explanation:
Area = side*side
side * side = 49
side * side = 7*7
side = 7 inches
Perimeter = 4*side
=4 * 7
= 28 inches
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
Answer:
The first step should be adding 14 to both sides of the equation.
Step-by-step explanation:
14 must be added on both sides of the equation to get 13y by itself. The ultimate goal is to get y by itself if we are solving for y.
Once 14 is added on both sides, you'll get:
13y = 56.
Then 13 would be divided from both sides.
y = 4.3
