Answer:
y = 2666.67
Step-by-step explanation:
Well to solve this we can make a system of equations.
x = cost of car alone
y = cost of accesories,
So now we plug in 8y for x in x + y = 24000.
(8y) + y = 24000
9y = 24000
Divide both sides by 9
y = 2666.666666
or 2666.67 rounded to the nearest hundredth.
Now that we have y we can plug that in for y in x=8y.
x = 8(2.666.67)
x = 21,333.33 rounded to the nearest hundredth.
<em>Thus,</em>
<em>accessories "y" cost around 2666.67.</em>

Answer:
Step-by-step explanation:
larger radius R=87/2
smaller radius r=65/2
larger semi circle=1/2×2×π×R=π×R=π×87/2=87 π/2≈136.6 m
smaller semicircle =π×r=π×65/2=65 π/2≈102.1 m
length of track=87+65+136.6+102.1≈390.7 m
Case 1 :
Radius, r = 5 feet.
Area,
Case 2 :
Diameter, d = 56 mm.
So, radius, r = d/2 = 28 mm.
Area,
Hence, this is the required solution.
