5500 milliliters equal how many liters show work
Eva8 [605]

Answer:

5.5 liters

Step-by-step explanation:

1 milliliter equals to 1/1000 part of a liter, which is 0.001 liter.

1 milliliter = 1 * 0.001 liter

So if you have 5500 milliliters that means it equals to 5500 times one milliliters and 1 milliliter = 1 * 0.001 liter, so for 5500 milliliters it is 5500 times as much

5500 * 0.001

5500 * 1/1000

5500 / 1000

5.5 liters

As long as you know this number 0.001 , then it is easily to calculate between liters and milliliters.

EXTRA:

To convert from amount A which is given in a certain quantity, to another quantity, you sometimes have to multiply and in other cases you need to divide by a certain factor. The factor defines the relationship between the quantities.

Suppose you have 1000 times 1 milliliter then you can find the amount in liters by multiplying that number of milliliters times 0.001.

It is easy to see that

1000 * 1/1000

1000 / 1000

= 1 liter, but that is easy, because I choose an easy number for the amount of milliliters to convert into liters. But it works exactly the same for any amount!

help me if you can...20-22 the midpoint M and one endpoint of GH are given. find the coordinates of the other endpoint.
kenny6666 [7]

Midpoint

x = (x1 + x2)/2

y = (y1 + y2)/2

19)

x = (x1 + x2)/2 = (5 + 4 )/2 = 4.5

y = y = (y1 + y2)/2 = (-6 + 3)/ 2 = -3/2= -1.5

Answer: Midpoint (4.5, -1.5)


20)

x = (x1 + x2)/2 = (-3 -2 )/2 = -2.5

y = y = (y1 + y2)/2 = (7 + 5)/ 2 = 6

Answer: Midpoint (-2.5, 6)

21)

x = (x1 + x2)/2 = (-2 + 8 )/2 = 3

y = y = (y1 + y2)/2 = (9 + 0)/ 2 = 4.5

Answer: Midpoint (3, 4.5)

22)

x = (x1 + x2)/2 = (-4 - 13/2 )/2 = -5.25

y = y = (y1 + y2)/2 = (1 - 6 )/ 2 = -2.5

Answer: Midpoint (-5.25, -2.5)

1.) p^2+14p-38=0<br> what the vertex?
Lelu [443]

Answer:

vertex = (- 7, - 87)

Step-by-step explanation:

given a parabola in standard form : ax² + bx + c : a ≠ 0

Then the x- coordinate of the vertex is

x_{vertex} = - \frac{b}{2a}

p² + 14p - 38 is in standard form

with a = 1, b = 14, c = - 38, hence

x_{vertex } = - \frac{14}{2} = -7

substitute x = - 7 into the equation for corresponding value of y

y = (- 7)² + 14(- 7) - 38 = 49 - 98 - 38 - - 87

vertex = (- 7, - 87)

I'm stuck on C, please help. Thank you
jonny [76]

Step-by-step explanation:

(x {}^{4}  - x) {}^{4} -  ( {x}^{4}  - x)

x {}^{16}   +  4( {x}^{12} ) - x + 6( {x}^{8} )( {x}^{2} ) + 4( {x}^{4} )( -  {x}^{3} ) +  {x}^{4}  -(  {x}^{4}  - x)

{x}^{16}  - 4 {x}^{13}  + 6 {x}^{10}  - 4 {x}^{7}  +  {x}^{4}  -  {x}^{4}  + x

{x}^{16}  - 4x {}^{13}  + 6 {x}^{10} - 4 {x}^{7}   + x

A supervisor finds the mean number of miles that the employees in a department live from work. he finds x overbar = 29 and s = 3
V125BC [204]

A supervisor finds the mean number of miles that the employees in a department live from work is 24. Then the correct option is B.

<h3>What is a z-score?</h3>

The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.

The z-score is given as

z = \dfrac{x-\mu }{s}\\

x = 29

s = 3.6

z = 1.5

Then the mean will be

1.5 = \dfrac{29 - \mu }{3.6}\\\\\mu = 29 - 5.4\\\\\mu = 23.6 \approx 24

More about the z-score link is given below.
