(b) use the your rewglts of part (a) to caloylate the exact valus of the following, (eave radicals, if any, in your anewers)s cos t sin e sin u tan s tan u 3. a farris whoel has radius 35 foet and it rotates at 1.4 revolutions per miute. (a) calculate its anrular speed in radians per minute. (b) calculate the linear speed of a point cn its rim in feet per minute. 4. the radius of each tire of a pick-up truck is 20 inches. it is moving at a speed of 72 miles per hour. (a) calculate its speed in inches per second. (b) calculate the angular speed of its tires in radians per second. (hint: make use of the linear speed in part (a) and the radius of the tires), (c) how many revolutions are the tires turning per second? round off to the nearest whole mumber. 2

step-by-step explanation:

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
