Answer: 210 tickets
Explanation:
1. Multiply the number of tickets he sold on Monday (21) by 3. (21x3=63)
2. Multiply the number of tickets he sold on Tuesday (63) by 2. (63x2=126)
3. Add all of those together to get the answer. (21+63+126=210)
Answer: 12/5 or 2 2/5
2 divide 5=2/5
2/5 times 6 = 12/5
or 2 2/5
<span>Answer:
K = (1/2) mv² + (1/2) Iω², where m is the ball mass, I is the ball's moment of inertia (2/5)mr², and ω is the angular velocity of the ball. Because the ball rolls without slipping, it is easy to see that v=ωr, or r=v/ω. Then,
K = (1/2)mv² + (1/2)(2/5)mr²ω²
= (1/2)mv² + (1/5)mv²
= (7/10)mv²
Setting potential at the top equal to kinetic at the bottom,
mgh=(7/10)mv²
v=âš{(10/7)(gh)}
= [(10/7)(9.8)(0.51)]^(1/2) = 2.672m/s</span>

Answer:
There are 68 dogs in the pound.
Step-by-step explanation:
Number of pit bull dogs in a pound = P = 23
Number of chihuahuas dogs in a pound = C = 17
Number of mutts dogs in a pound = M = 28
Total number of dogs in a pound = T
There are 68 dogs in the pound.
