60g/12miles = 5g/mile
So, 1200g / 5g = 240 miles
Draw a diagram to illustrate the problem as shown below.
When the smaller gear rotates through a revolution, it sweeps an arc length of
2π(4) = 8π inches.
Part 1
The same arc length is swept by the larger gear. The central angle of the larger gear, x, is
7x = 8π
x = (8π)/7 radians = (8π)/7 * (180/π) = 205.7°
Answer: 205.7° (nearest tenth)
Part 2
When the larger gear makes one rotation, it sweeps an arc length of
2π(7) = 14π inches.
If the central angle for the smaller gear is y radians, then
4y = 14π
y = 3.5π radians = (3.5π)/2π revolutions = 1.75 revolutions
Answer:
The smaller gear makes 1.75 rotations
Answer:
y < x
y < 4
Step-by-step explanation:
Dotted line means < or >, and since the shaded region is below the lines y = 4 and y = x, the answer is A.

Answer: 1.118
Step-by-step explanation:
Factor x Factor = Product
0.26(Factor) x 4.3(Factor) = 1.118(Product)
To check your work, divide the product by one of the factors and the result you should get is the other factor.
1.118(Product) ÷ 4.3(Factor) = 0.26(Factor)
-or-
1.118(Product) ÷ 0.26(Factor) = 4.3(Factor)
To show work:
