Answer:

200 = 10 Hours, 400 = 5 Hours, 600 = 3 Hours & 18 Minutes.

Step-by-step explanation:

2000 / How many miles it travels per hour.

2000 / 200 = 10

2000 / 400 = 5

2000 / 600 = 3.3..

A sphere rolls up an inclined plane of inclination angle 30 degree. At the bottom of the incline the center of mass of the spher

Zigmanuir [339]

Answer: The sphere is 0.002548 cm travel up the plane.

Step-by-step explanation:

Since we have given that

Inclination angle = 30°

Translational speed = 0.25 m/s

As we know that

$KE=0.5\times lw^2=PE$

and

Length of solid sphere is given by

$l=\dfrac{2Mr^2}{5}$

So, it becomes,

$KE=0.5\times \dfrac{2Mr^2}{5}w^2=Mgd\sin \theta$

And $0.25\ m/sv=rw$

So, it becomes,

$1\times (0.25)^2=5\times d\times 9.81\times \sin 30^\circ\\\\0.0625=49.05d\times \dfrac{1}{2}\\\\\dfrac{0.125}{49.05}=d\\\\d=0.002548$

Hence, the sphere is 0.002548 cm travel up the plane.

8/9 divided by -1 4/15

Marina86 [1]

You can use the keep it, change it, and flip it method. Keep the 8/9. Change the division to multiplication. Flip -14/15 (it becomes -15/14). So, your answer would become 20/21.

3/8x - 1 = 5/8 solve for x

Blababa [14]

Answer: x = 13/3 or x = 4.33333....

Solution: ⅜x -1 +1 = ⅝ + 1

Simplify: ⅜x = 13/8

Multiply both sides by eight: 8 x ⅜x = 133 x 8 divided by 8

Simplify: 3x = 13

Divide both sides by three: 3x/3 = 13/3

Simplify: x = 13/3
