carlos has a collection of old vinyl records. to play some of the records, the turntable rotates through an angle of 3 2 π radians in 1 second. how many revolutions does the record make in one minute?

2.093 revolutions per minute

Step-by-step explanation:

1)just multiply the equation by 60 because their is 60 seconds in 1 minute.

SO

    (  3/2(pi))times 60

            =2.093 revolutions in 1 minute  

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
