5 hours
715/11 = 65
325/65 = 5
Answer:
14 : 21
Step-by-step explanation:
---> 2:3 ----> 2+3=5
---> Stick's length = 35 inches
<u />
<u>For the first portion</u>
2/5 x 35
2/1 x 7
= 14 inches
<u>For the second portion</u>
3/5 x 35
3/1 x 7
= 21 inches
To confirm: 14 + 21 = 35 inches
14 : 21
Divide both by 7
2 : 3
Y = 2x-3
The second line will have its Y-Intercept at -3 and its slope will be up 2 and over 1 which will allow it to go through (4,5) and the line will be parallel to Y = 2x+2
Answer:
3.5 (D)
Step-by-step explanation:
focusing on the right side of the decimal, 5 rounds 5 to 6. 6 rounds 4 to 5. Anything 5 or above rounds up! So the .5 rounds 4 to 5, making the answer 3.5. So sorry if this doesn't make sense, its kind of hard to explain.
Find the rate in which both balls make one full rotation around the track.
Ball A:

It takes 30 seconds for Ball A to make a full rotation.
Ball B:

It takes 20 seconds for Ball B to make a full rotation.
Find the least common multiple of 20 and 30 to find the time at which they'll meet.
Multiples of 20: {20,40,60}
Multiples of 30: {30,60}
60 is the least common multiple of both 20 and 30.
The balls will meet again at
60 seconds.
