Answer:
44.75
Step-by-step explanation:
5.5 + (- 2.75) - 7(18 ÷ - 3)
5.5 - 2.75 - 7(- 6)

2.75 + 42
44.75
Answer:
301.44 cubic units
Step-by-step explanation:

Answer:
First find the circumference of both wheels
C = pi d
Large wheel = 3.14 * 60
= 188.4
Small wheel = 3.14 * 18
= 56.52
Divide them both with divide 600 by the circumference
Large wheel = 600/188.4 = 3.18 or <em>3 rotations</em>
Small wheel = 600/56.52 = 10.61 or <em>11 rotations</em>
<em>b. 2 large wheels. This is because you can cover more distance with large wheels that small wheels. Large wheels are also worth the energy.</em>
