Answer:

B) is the correct answer

Step-by-step explanation:

You have a perfect 100 until you get a question wrong which each question is worth 3.3 points. So, if you answered 7 wrong the x would be replaced by the 7 and the grade would decrease steadily.

If a globe rotates 150 degrees in 5 seconds, how many rotations does it make in 30 seconds? I got 900 seconds for my answer am I
Maksim231197 [3]

Start with a proportion, to get the number of degrees in 30 seconds:

         (150 degrees / 5 seconds) = ('D' degrees / 30 seconds) .

Cross multiply the proportion:  (150 x 30) = 5 x D

                                                     4,500  =  5 x D

Divide each side by  5 :                  900 = D

The globe turns 900 degrees in 30 seconds.

How many rotations is that ?
Each rotation is 360 degrees.
So 900 degrees is
                               (900 / 360) = <em>2.5 rotations</em> in 30 seconds.
