One month = 5000
Number of months before the spark plugs need to change :
15000 ÷ 5000 = 3
The sparks can last 3 months before it needs to be changed.
Number of times it need to change in a year = 12 ÷ 3 = 4
-----------------------------------------------------------------------------
Answer : It needs to be change 4 times a year.

Answer:
after 10 seconds
Step-by-step explanation:
h=-16t^2+v0*t+h0
ground level is h0 with a measure of 0
160 is v or velocity
0=-16t^(2)+160t+0
0=-16t^(2)+160t
0=16t(-t+10)
0/16t=(-t+10)
0=-t+10
-10=-t
10=t
t=10
It is not enough to describe the oppostite rays only with the statement that they have the same endpoint. Besides the same endpoint opposite rays are characterized with opposite drection.
So, the student should answer: VW and VZ are opposite rays because they have the same endpoint and the the opposite direction.
Answer:
The expression is T = b+s
Step-by-step explanation:
If b represents the number of bikes and s represents the number of skateboards Donte is planning to repair to save up money for college, the total number of things he can repair in a day will be expressed as the sum of number of bikes and number of skateboards i.e b+s = T
Given that He can repair up to 2 bikes per day, the total and 4 skateboards per day this means that b = 2 and s = 4
Total number of thing's he can repair in a day given this amount T = 2 + 4 = 6 things
