Answer:
Once.
Step-by-step explanation:
To find when they chirp together, we must find the LCM of the two numbers. The LCM, or least common multiple of 13 and 5 is 65. Therefore, after 65 minutes is the first time they chirp together. Then we can multiply 65 by 2 to see if they chirp a second time. 65x2 is 130, but 8AM-10AM is only 120 minutes, therefore they do not chirp together more than 1 time.
Answer:
x+y=5
Step-by-step explanation:
<h3>This cylinder is 8 inches tall and has a volume of 200 π in³. Find the area of the cross section.</h3>
Answer: cross section = 25π in²
Step-by-step explanation:
Cylinder volume is the product of the cross section by height.
Then cross section = cylinder volume/height = 200 π in³/8in = 25π in²
Answer: 25π in²
37/11 is correct just multiply 3*11 and add four
Answer: 15 players.
Step-by-step explanation:
number of games played in the tournament = 105 games
nunber of games played by each player against another = 1 game each.
Solution:
Number if player who participated in the tournament.
if each player played a game against every other player, and they were 105 games played at the tournament.
n ( n – 1 ) /n = m
= n ( n – 1 ) 2 = 105
open the bracket
n^2 – n = 210
n^2 – n – 210 = 0
( n – 15 ) ( n + 14 ) = 0
n = 15
15 players Participated In the tournament.
