Answer:

1 3/40

Step-by-step explanation:

4/20 + 7/8

We can simplify 4/20 by dividing the top and bottom by 4

1/5 + 7/8

We need to get a common denominator of 50

1/5 * 8/8 = 8/40

7/8 * 5/5 = 35/40

8/40 + 35/40

43/40

Changing this to a mixed number

1 3/40

1,400 • 5 = 7,000

So no, it it's not reasonable.

g My Notes Water flows from the bottom of a storage tank at a rate of r(t) = 200 − 4t liters per minute, where 0 ≤ t ≤ 50. Find

Arada [10]

Answer:

4,200 liters

Step-by-step explanation:

The flow rate is given by:

$r(t) = 200 - 4t$

Integrating the flow rate expression from t=0 to t=30 minutes, yields the total volume that flows out of the tank during that period:

$\int\limits^{30}_0 {r(t)} = \int\limits^{30}_0 {(200 - 4t} )\, dt \\V=(200t - 2t^2)|_0^{30}\\V= (200*30 -2*30^2)-(200*0 -2*0^2)\\V=4,200\ liters$

4,200 liters of water flow from the tank during the first 30 minutes.
