Step-by-step explanation:
let the radius of one circle be r and the other be R,
there fore,
2πr + 2πR = 80
=> 2π( r + R) = 80
but we know that, R =2r
=> 2 π ( 3r) = 80
=> 3r = 40/π
=> r = 40/3π
taking the value of pi to be 3.14
=> r = 40/9.42
=> r = 4.246
hence the larger radius = 2r => 8.492
Answer:
C
Step-by-step explanation: Because Median is all the numbers put in order least to greatest. Then the middle number.
Store A: 15, 25, 45, 55, 64
Store B: 22, 35, 40, 65, 71
4:15 to 5:00 is 45 minutes; 5:00 to 5:50 is 50 minutes. 50+45=95 minutes = 1 hour and 35 minutes.
Because all the digits are the same, each digit is worth 10x the one to its right and 1/10 of the one to its left.
This is because we count in base 10. This is also why we can expand this number to become
9*10^6+ 9*10^5+ 9*10^4+ 9*10^3+ 9*10^2+ 9*10^1 +9*10^0.
