Can somebody help me evaluate 2000(0.085)

1 answer:

4 0

That represents a simple multiplication, but we can make it with fractions so it is more instructive changing the decimal to fraction:
2000(0.085)
= 2000*0.085
= 2000(85/1000)
= 2*85
= 170
and this way we do not need the calculator nor pencil

Arranging the given data in ascending order:

1, 2, 2, 3, 3, 4, 7, 7, 7, 9

Meadian is the middle-most observation.

i.e. The Median here is average of 3 and 4.

= (3+4)/2

= 7/2

=3.5

Hope it helps...

There are 200 ounces in 6 liters. How many milliliter (ml) are in 6 liters? (How to do in dimensional analysis?)

Dima020 [189]

Answer:

6000 mL

Step-by-step explanation:

The prefix "milli-" is an SI standard prefix meaning 1/1000. So, 1 mL = (1/1000)L.

When doing dimension changes, you always want to use scale factors that have a value of 1, which is to say the numerator is equal to the denominator. For converting liters to milliliters, the scale factor you want will have mL in the numerator and L in the denominator:

(1 mL)/(1/1000 L) or (1000 mL)/(1 L)

To do your conversion, multiply your liter volume by this factor.

$(6\text{ L})\times\dfrac{1000\text{ mL}}{1\text{ L}}=\dfrac{6\times1000\text{ mL$\cdot$L}}{1\text{ L}}=6000\text{ mL}$

6 liters is 6000 milliliters.

You will notice that the dimensions "L" cancel, which is the point of the exercise.

Additional comment

6 L is closer to 202.884 fluid ounces. The conversion factor is ...

$\dfrac{128\text{ fl oz}}{231\text{ in}^3}\times\dfrac{1\text{ in}^3}{(0.254\text{ dm})^3}\times\dfrac{1\text{ dm}^3}{1\text{ L}}=\dfrac{128\text{ fl oz}}{3.785411784\text{ L}}\quad\text{exactly}$

G^2 – 9 factor each expression please help

cestrela7 [59]

Using the difference of squares rule, we can say
g^2 - 9 = g^2 - 3^2
g^2 - 9 = (g-3)(g+3)

So, the answer is (g-3)(g+3). This is the same as (g+3)(g-3)

What angle of inclination (to the nearest whole degree) does a stairway make with the floor if the steps have a tread of 11 inch

faltersainse [42]

tan x = opposite / adjacent
tan x = 6 / 11
tan x = 6 / 11
x = 28.61 (or 29 degrees rounding to the nearest whole degree)
