Most important rule of Pre- algebra and algebra, do the opposite operation.
So what you do is subtract 3/8 to isolate the variable. 1/2 = 4/8 so just do 4/8-3/8 and get 1/8 so m = 1/8
Answer:
<h2><u>
x = 8.2</u></h2>
Step-by-step explanation:
A^2+B^2=C^2 is the pythagorean theorem to find a missing siede of a triangle.
First triangle on the right:
5^2+B^2=10^2
25+B^2=100
B^2=75
B=8.66025404
B=8.7
Second triangle of left:
3^2+B^2=8.7^2
9+B^2=75.69
B^2=66.69
B= 8.16639455
B=8.2
x=8.2
Answer:
26.3 rev/min
Step-by-step explanation:
The angular velocity (ω) is the linear velocity divided by the radius ( r= 80 feet)
ω = 220/80 = 2.75 rad/s
The angular velocity and the frequency are related by:
ω = 2π*f
2.75 = 6.28*f
f = 2.75/6.28
f = 0.438 rev/s * 60s/1min
f = 26.3 rev/min
Y intersect is the answer
