B.)
I can tell because the sin func starts from the top at 0 (if sin is positive)
C because there are 60 seconds in a minute so if you multiply 600 x 60 you get 36000
64 hours per hour average
350 miles ÷5.25 hours in which it took= 63.63 rounded is 64 mph average
Answer:
3x = 50 - 10y
Step-by-step explanation:
Here, x represents the number of 3 lb weights and y represents the number of 10 lb weights,
So, total weight of 3 lb weights = 3x
And, the weight of 10 lb weights = 10y
Total weight of all his weights = 3x + 10y
According to the question,
Total weight = 50 lb,
⇒ 3x + 10y = 50
Or 3x = 50 - 10y
Which is the required equation.
Second option is correct.
