maybe the second option
Answer:
28126 total
Step-by-step explanation:
1240-780=460
24.50 - 20%=4.90
24.50-4.90
780*24.50=19110
19.60 * 460=9016
19110+9016=28126
You got a picture for this
Answer:
20 seconds
Step-by-step explanation:
The speed of A is:
sA = 18 units / 3 seconds = 6 units/second
The speed of B is:
sB = -15 units / 3 seconds = -5 units/second
The relative speed is:
s = sA − sB
s = 6 units/second − (-5 units/second)
s = 11 units/second
The time for the distance between them to be 220 units is:
220 units = 11 units/second × t
t = 20 seconds
Y = 3
This is because according to the all the numbers we have, all they did was divide the numbers from the bigger triangle by 2. So, 10 divided by 2 is equal to 5. That is where the 5 came from. 7 divided by 2 is equal to 3.5. That is where the 3.5 came from. 6 divided by 2 is equal 3. That is why y is equal to 3.
Hope this helps, have a great day, stay safe and positive.
