Answer:
2.05 and 14.61
Step-by-step explanation:
On Edg
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
3 and 3/5
I believe thats a mixed number .. sorry its been so long
For this case, what you must do is add the area of each of the triangles to find the total area of the polygon.
We have then:
A = 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2
A = 16
Equivalently, as the area of each triangle is the same, then:
A = 2 * (8)
A = 16
Answer:
the area of the polygon is:
16
Option 3
6 math books would be 126
5 English books would be 150
126+150=276
