Equality Properties

Step-by-step explanation:

<u>Step 1: Define</u>

(r - 74)/4 = 4

<u>Step 2: Solve for </u><em><u>r</u></em>

  1. Multiply 4 on both sides:                    r - 74 = 16
  2. Add 74 on both sides:                        r = 90

Oil leaked from a tank at a rate of r(t) liters per hour. the rate decreased as time passed, and values of the rate at two hour
Galina-37 [17]
The given data is
t, h:            0     2     4     6     8   10
r(t), L/h:   8.6  7.9  6.8  6.4  5.7  5.3

The lower and upper estimates for the total amount that leaked may be computed as the Left and Right Riemann sums.

The shape of the graph of r versus will determine which of the two sums yields an upper or lower sum.
The plot of the graph is shown below.

The Left Riemann sum is
Sl = 2*(8.6+7.9+6.8+6.4+5.7) = 70.8 L

The Right Riemann sum is
Sr = 2*(7.9+6.8+6.4+5.7+5.3) = 64.2 L

Answer:
The lower estimate for oil leakage is 64.2 L
The upper estimate for oil leakage is 70.8 L

Easy Question, Easy Points<br><br><br>Topic: Volume<br><br><br>Focus on question 12
Sever21 [200]

Answer:

The air is .6m^3

Step-by-step explanation:

The volume of a cube is

V = s^3 where s is the side length

The volume of the tank is

V = 1^3 = 1 m^3

The volume of the water is 1 by 1 by .4

V = l*w*h

   = 1 *1*.4

   = .4 m^3

The difference must be filled by air

1- .4 = .6 m^3

The air is .6m^3
