Answer:
1055.99 rad/min
Step-by-step explanation:
Given that,
The diameter of a bicycle, d = 24 inches
Radius, r = 12 inches
The bicycle is travelling at 12 mi/h.
We need to find the angular speed of the wheels in rad/min.
We know that,
1 mi/h = 0.0166667 mi/min
It means,
12 mi/h = 0.2 mi/min
Also,
12 inch = 0.000189394 miles
The angular speeds of the wheels is given by :
So, the angular speeds of the wheels is 1055.99 rad/min.
Answer: M= -5
Step-by-step explanation: -5x+12
4(x - 2) + 6 = 2(5x - 6) <em>use distributive property</em>
(4)(x) + (4)(-2) + 6 = (2)(5x) + (2)(-6)
4x - 8 + 6 = 10x - 12
4x - 2 = 10x - 12 <em>add 2 to both sides</em>
4x = 10x - 10 <em>subtract 10 from both sides</em>
-6x = -10 <em>divide both sides by (-6)</em>
x = 10/6
<h3>x = 5/3</h3>
Answer: Hello there!
we know that she earns $8 in the job 1 and $12 in the job 2; let's call J1 the amount of hours worked in the job 1, and J2 the number of hours worked in the job 2, then we have the system of equations:
J1 + J2 = 30
J1*$8 + J2*$12 = $268
We can isolate J1 in the first equation and obtain:
J1 = 30 - j2, and now we can replace this in the second equation and obtain the value of j2:
J1*$8 + J2*$12 = $268
(30 - J2)*$8 + J2*$12 = $268
$240 +$4*J2 =$268
J2 = ($268 - $240)/$4 = 28/4 = 7 hours
She worked 7 hours in the job 2
you can replace it in the first equation and get:
7 + J1 = 30
J1 = 30 - 7 = 23 hours
she worked 23 hours in the job 1.
