Harry can rake the leaves in the yard 8 hours faster than his little brother Jimmy can.
<span>If they join to work together they can complete the job in 3 hours. </span>
<span>1/x + 1/(x - 8) = 1/3 </span>
<span>3(x - 8) + 3x = x(x - 8) </span>
<span>x^2 - 14x + 24 = 0 </span>
<span>(x - 12)(x - 2) = 0 </span>
<span>Solutions: </span>
<span>x = 2 </span>
<span>x = 12 </span>
<span>Jimmy can complete the job on his own in 12 hours.</span>

Answer:
7.75 m
Step-by-step explanation:
First find the circumference. Use the formula C = 2πr
C = 2(3.14)(3)
C = 18.84
148° is a fraction of the entire circle which is 360°
Multiply
18.84/1 x 148/360
2788.32/360
7.745
