Answer:
Rotations of tire to travel 500 feet: 95.54
Step-by-step explanation:
Circumference = 20 x 3.14 = 62.8 in
500 feet = 500 x 12 inches = 6,000 in
Rotations = 6000 / 62.8 = 95.54 rotations of tire
In order to solve the given expression follow these steps:
1. Take the square roots on both sides in order to get rid of the power on the left side:
√(x-5)² = ±√3
x - 5 = ±√3
2. add 5 on both sides:
x-5 + 5 = 5 ±√3
x = 5 ±√3
Then, the solution is x = 5 ±√3

Answer:Option D is correct.Step-by-step explanation:We are given with a solid figure with cuboid in base and square based pyramid in top.we have to find Surface of the figure.Surface Area = Curved surface ares of cuboid + area of base of cuboid + lateral surface area of pyramid.Length of the cuboid, l = 8 cmwidth of the cuboid , w = 8 cm height of the cuboid , h = 11 cm Lateral surface area of pyramid = 4 × Area of a triangle Base of triangle , b = length of cuboid = 8 cmHeight of the triangle ,H = 8 cmSurface Area = 2 × h × ( l+w ) + l × b + 4 × 1/2 × b × H = 2 × 11 × ( 8 + 8 ) + 8 × 8 + 2 × 8 × 8 = 22 × 16 + 64 + 128 = 352 + 192 = 544 cm²Therefore, Option D is correct.
