10.A water tank has strps inside it. A monkeyis sitting on topmost floor(i.e.,the first step).The water level is at ninth step.

soldi70 [24.7K]

Answer:

7 steps.

Step-by-step explanation:

Since the monkey is sitting on the first step already you can subtract 9 by 1 to find the amount of steps left.

9-1 = 8 steps left

The monkey jumps 3 steps down

8-3= 5 steps

Then jumps 2 steps up

5 + 2 = 7 steps

The monkey has 7 more steps until he reaches the water level.

Two gears are connected and are rotating simultaneously. The smaller gear has a radius of 2 inches, and the larger gear has a ra

shutvik [7]

R - radius of the larger circle
r - radius of the smaller circle

Circumference of the larger circle = $2R\pi=2\times 8\pi=16\pi$
Circumference of the smaller circle = $2r\pi=2\times 2\pi=4\pi$

Part 2: During one complete rotation of the larger gear both gears pass the same distance $16\pi$ .
Therefore, the smaller gear makes $\frac{16\pi}{4\pi}=4$ complete rotations.

Part 1: During one complete rotation of the smaller gear both gears pass the same distance $4\pi$ .
Therefore, the larger gear makes $\frac{4\pi}{16\pi}=\frac{1}{4}$ of a complete rotation.
Since one complete rotation corresponds to 360 degrees, 1/4 of a complete rotation corresponds to 360/4=90 degrees.
