Answer:
3750, 8888.89, 1920
Step-by-step explanation:
p=m/v
p1=240/(0.04^3)= 3750 kg/m^3
p2=240/(0.03^3)= 8888.89 kg/m^3
p3=240/(0.05^3)= 1920 kg/m^3
Answer: A. 7 hours
Step-by-step explanation: divide
3.4, 4.7, 1.9, 7.6, and 6.5
Rearrange the numbers in ascending orders:
1.9 , 3.4, 4.7, 6.5, 7.6
⇒ The median (the number in the middle) is 4.7
Answer: False
To find the interior angle, you use the formula ((n - 2) x 180) / n (where n is the number of sides).
So, ((20 - 2) x 180) / 20 = 162
To find the exterior angle, you merely take away the interior angle from 180.
180 - 162 = 18, so the exterior angle is 18 degrees
Another, easier, way is to just divide 360 by n. All exterior angles always add to 360. Thus, 360 / 20 = 18 degrees
For this case we have that by definition, the volume of a parallelepiped is given by:
![V = l * w * h](https://tex.z-dn.net/?f=V%20%3D%20l%20%2A%20w%20%2A%20h)
Where:
l: It's the long
w: It is the width
h: It's the height
From the figure we have the following data:
![V = 975 \ ft ^ 3\\h = 9 \ ft\\w = 4ft\\x =?](https://tex.z-dn.net/?f=V%20%3D%20975%20%5C%20ft%20%5E%203%5C%5Ch%20%3D%209%20%5C%20ft%5C%5Cw%20%3D%204ft%5C%5Cx%20%3D%3F)
We must find the value of the length of the parallelepiped:
![975 = x * 4 * 9\\975 = 36x\\x = \frac {975} {36}\\x = 27.083](https://tex.z-dn.net/?f=975%20%3D%20x%20%2A%204%20%2A%209%5C%5C975%20%3D%2036x%5C%5Cx%20%3D%20%5Cfrac%20%7B975%7D%20%7B36%7D%5C%5Cx%20%3D%2027.083)
Answer:
![x = 27.1 \ ft](https://tex.z-dn.net/?f=x%20%3D%2027.1%20%5C%20ft)
