Step-by-step explanation:
we just have to set up a simple expression
0.59(640)
this equals

Answer:
0.6 hours
Step-by-step explanation:
Let's say J is Jen's speed (cake pops per hour), and let's say M is Maryna's speed (cake pops per hour).
Let's say there are 12 cake pops total that need to be made. Jen made half of the cake pops in 3 hours, so she made 6 cake pops in 3 hours. So her speed is 2 cake pops per hour.
Then, Jen and Maryna made the other half of the cake pops in 1/2 hour. Therefore, their combined speed is:
J + M = 6 cake pops / (1/2 hr)
J + M = 12
2 + M = 12
M = 10
So Maryna can make 10 cake pops per hour.
If Maryna was working alone, the amount of time it would take her to make 6 cake pops is:
6 cake pops / (10 cake pops per hour) = 0.6 hours
It would take 0.6 hours, or 36 minutes.
The first one is d and the second is b!! also i recommend downloading mathpapa it will really help u :D
The domain is all possible x values.
In this case it goes from -2 to 6
So your domain is [-2,6] which is option b
Since the values -2 and 6 are included you use greater than or equal to and less than or equal to.
