Answer:
25
Step-by-step explanation:
To calculate rate, divide the number of cans by the time to get "Cans per minute".
300/15min = 20/min
Let m represent minutes and c for cans.
We write an equation for the problem:
c = 20m
We want to know the time for 500 cans, so substitute 500 for c.
500 = 20m
Isolate m and solve:
m = 500/20
m = 25
It will take 25 minutes to put 500 labels.
namely, how many times does 0.4 go into 6⅓? or 6⅓ ÷ 0.4.
first off, let's convert the mixed fraction to improper, and the decimal to a fraction . We can always convert the decimal to a fraction by simply <u>adding as many zeros on the denominator as there are decimals and lose the dot atop</u>, let's do so.

Answer: C
Step-by-step explanation:
V 1 = 500 mph,
v 2 = 50 mph
The resultant velocity:
v r² = v 1 ² + v 2 ²
v r ² = 500² + 50² = 250,000 + 2,500 = 252,500
v r = √252,500 = 502.49378 ≈ 502.49 mph
Answer: the magnitude of the resultant velocity is 502.49 mph.
