Can someone me with 1 to 2 . with explanation. and how you got the answers

So, the rate per 7 minutes is 7:196

To find the unit rate (how many spins per minute) we need to divide the 196 by 7.

196/7 = 28

The unit rate is 1:28

At this rate, the unicycle makes 420 revolutions per 15 minutes. We find this by 28 * 15 = 420.

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
