Answer:
Step-by-step explanation:
let a number be x
let another number be x+1
x+x+1=20
2x=20-1
x=19/2
x=9.5
therefore one number is 9.5 and another number is x+1=9.5+1=10.5
Answer; x=10
add the 4 and 26 which is 30, so the equation then would be; 3x=30 and that’s how you get 10 as you answer.
hope this helped you out!
Wait where’s the x in the equation?
Answer:
<em>The larger gear will rotate through 156°</em>
Step-by-step explanation:
<u>Arc Length</u>
The arc length S of an angle θ on a circle of radius r is:

Where θ is expressed in radians.
The smaller gear of r1=3.7 cm drives a larger gear of r2=7.1 cm. The smaller gear rotates through an angle of θ1=300°.
Convert the angle to radians:

The arc length of the smaller gear is:


The larger gear rotates the same arc length, so:


Solving for θ2:




The larger gear will rotate through 156°
