The chance is 3/5 that the light will be green.
Added together the total seconds for the traffic light to complete the cycle is 120 (38+72 (1 min and 12 sec) +10.
And the green light proportion is: 72/120
We simplify by dividing by 12, which is a factor and we get: 6/10 that simplifies to 3/5.
Hope this helps!
I believe the answer to this is correct and i believe he did this by adding(i think)
Multiples of 30 : 30,60,90,120,150....
and the first one that 4 goes into evenly is 60
It's an easy problems. what equations are you trying to find?
Answer:
$24.50
Step-by-step explanation:
60% of $50= $30
$50-$30= $20
15% of $20= $4.50
$20+$4.50= $24.50
