Answer:

About 90.73 meters/min.

Step-by-step explanation:

Dimensional analysis is done by multiplying the wanted unit over the current unit in equal measure, or the other way around.

First, we will convert feet to meters, using that 1 ft = .4048 m.

32ft/6.45sec * .3048m/1ft = 32/6.45sec * .3048m = 9.7536m/6.45 sec.

Second, we convert seconds to minutes, using that 60 sec = 1 min.

9.7536m/6.45sec * 60sec/1min = 9.7536*60m/6.45min ≈ 90.7311627m/min.

The average density of the material in intergalactic space is approximately 2.5 × 10–27 kg/m3. what is the volume of a lead samp
Lesechka [4]

Answer:

e. 1.8\times 10^{-6}m^3

Step-by-step explanation:

It is given that,

The density of intergalactic space material is 2.5 \times 10^{-27} kg per cubic meter.

And the volume of intergalactic space material is 8.0\times 10^{24} m^3

So the mass of that much intergalactic space material is,

m= \rho\times v, where 'm' is the mass, and 'v' is the volume.

Putting the values we get,

m=2.5 \times 10^{-27}\times 8.0 \times 10^{24}

m=20\times 10^{(-27+24)}=20\times 10^{-3} kg

It is also given that the mass of lead is the same as the mass of the intergalactic space material. Therefore, the mass of lead is 20 \times 10^{-3}=2 \times 10^{-2}kg

So the volume of lead is,

v=\frac{m}{\rho} =\frac{2 \times 10^{-2}}{11300} = 0.00000177 m^3

v=1.77 \times 10^{-6}=1.8\times 10^{-6}m^3

So the volume of lead is v=1.8\times 10^{-6}m^3.

Emily spent $55 from her savings on a new dress. explain how to descibe the change Emily's savings balance in 2 different ways
Step2247 [10]
S= savings before she bought the dress   s - $55 would be her new balance after she bought the dress.

We could also talk about her savings now (after her purchase).   If we let n=now
n + $55 would be her balance before she bought the dress.

There're some old video games you sell on Ebay for $6, $7 and $9. The titles include " The Pirates", "Under the sea" and "The dr
aniked [119]

Answer:

2/9

Step-by-step explanation:

We have 3 video games

I will assume that pirates have a water theme, so 2 have a water theme

That leaves 1 game with no water theme

P (no water theme) = games with no water theme/ total

                                =1/3

The games are 6 7 and 9 dollars

2 games are at least 7 dollars

P( at least 7 dollars) = games at least 7/ total

                                =2/3

P ( no water theme at least 7 dollars) = P (no water theme) * P( at least 7 dollars)

= 1/3*2/3

 = 2/9
