Answer:

  8 cm

Step-by-step explanation:

See the diagram below.

The triangle formed by the radius, half the chord length, and the distance (d) from the center to the water is a right triangle with hypotenuse 20 cm and one leg length 16 cm. Then the other leg (d) can be found using the Pythagorean theorem:

  d^2 + 16^2 = 20^2

  d = √(400 -256) = 12

The depth of the water is the difference between this distance and the radius, so is ...

  20 cm - 12 cm = 8 cm

The maximum depth of the water in the pipe is 8 cm.

The time t required to empty a tank varies inversely as
vesna_86 [32]

If t and r are inverse proportional to one another, then for some constant volume V we have

V = tr

It takes 45 min to empty a tank containing at 300 gal/min, so the tank contains

V = (45\,\mathrm{min}) \left(300\dfrac{\rm gal}{\rm min}\right) = 13500\,\mathrm{gal}

of liquid.

If it's emptied at 500 gal/min, it would take

13500\,\mathrm{gal} = t \left(500\dfrac{\rm gal}{\rm min}\right) \implies t = \boxed{27\,\mathrm{min}}

Lexi has already jarred 19 liters of jam and will jar an additional 9 liters of jam every day. How many days does lexi need to s
Marysya12 [62]

Answer:

Lexi need to spend <u>6 days</u> to fill the jar with 73 liters of jam.

Step-by-step explanation:

Given:

amount of jam already had in jar =19 liters

amount of jam added each day in jar = 9 liters.

Total number of jam to be needed in jar = 73 liters.

We need to find the number of days required to jar 73 liters.

Solution:

To find the number of days required to jar 73 liters will be equal to amount of jam already had in jar plus amount of jam added each day in jar multiplied by number of days.

framing in equation form we get;

19+9x= 73

Subtracting both side by 19 we get;

19+9x-19=73-19\\\\9x = 54

Dividing both side by 9 we get;

\frac{9x}{9}=\frac{54}{9}\\\\x=6\ days

Hence Lexi need to spend <u>6 days</u> to fill the jar with 73 liters of jam.
