Answer:
Its B, y=-0.89x^2+3.24x+11.93
Step-by-step explanation:
mark brainest pls
So, let's say the soft drink equals y and the sandwich equals x.
x + y = 9.9
The sandwich costs 3.5 times as much as the soft drink
x = 3.5y
Therefore, we can replace x with 3.5y since they're the same thing
3.5y + y = 9.9 <-- That's the equation :)
Answer:
1225π
Step-by-step explanation:
The question concerns the volume of the cylinder.
The formula of the volume is:
, where r is the radius and h is the height.
Plugging the given numbers into the formula, we find that:

The result - 1225π shows that the cylinder can be filled fully with that given amount.
Answer:
14 gel pens/minute
Step-by-step explanation:
divide the amount by time.
210/15 = 14
6x^2 + 37x - 60 = 6x^2 - 8x + 45x - 60 = 2x(3x - 4) + 15(3x - 4) = (3x - 4)(2x + 15)
