Answer:
A. Yes, the slope is the same between each pair of points
Step-by-step explanation:
First of all, B and D are stating 2 opposite things in the same sentence, allowing us to instantly eliminate those choices. Second of all, you got C, and it said it was wrong, which makes sense because it does show a constant rate of change. This concludes by process of elimination, that the answer is A. Third of all, I hope this helps!
2 Gallons = 32 Cups.
32 - 12 (because he served them to his guests)= 20.
20 Cups of soup were left after the party.
Answer:
Step-by-step explanation:
It's geometric. The nth term differs by -5 when compared to the n+1 term.
Sum 0 to n a(-5)^n-1 where a = 2
I think this is what you want, but there is also a formula. See below.
Sum = a (r^n - 1)/(r - 1)
Is that supposed to be y=-2x+1?
i cannot solve without the proper equation lol
Answer:
It takes 100 minutes to fill the tank.
Step-by-step explanation:
Let the length of the pipe used for filling the tank be h
Then
Volume of the pipe = volume of the tank
Step 1: Finding the volume of the pipe
The pipe is in cylindrical form with height h and diameter 20m
The volume of the pipe =
Where r is the radius of the pipe
r =
r =
r = 10cm =
The volume of the pipe
=>
=>
=> -----------------------------------(1)
Step 2: Finding the volume of the tank
The volume of the tank =
Where r is the radius of the tank
r =
r =
r = 5
The volume of the pipe
=>
=> -------------------------------------(2)
Equating (1) and (2)
=
= 50
h = 50 X 100
h =5000m =5km
The flow rate of water through the pipe = 3 km/hr
time taken to travel 3 km = 1 hours
so time taken 1 km = hours
To Travel 5 km
=> hours
=> hours
converting into minutes
=>
=>
=> 100 minutes
