This is the concept of density, volume and mass of different materials; To calculate for the volume of an aluminium material with density of 2.375 grams per cubic centimeter and a mass of 0.78 Kilogram we proceed as follows;
Density=mass/volumemaking volume the subject we get;volume=mass/densitythus;mass=0.78 kg= 780 gdensity=2.375 g/cm^3Hence,volume=780/2.375=328.421 cm^3

The volume of a packing box is 5 – x cubic feet. The width of the box is x feet and the length is x – 2 feet. The height is give
photoshop1234 [79]
By definition we have that the volume is given by
 V = h * w * l
 where
 V: Volume
 h: height
 w: width
 l: length
 Clearing the height we have:
 h = V / (w * l)
 h = (5 - x) / ((x) * (x - 2))
 The expression is not defined for the values of x that make the denominator zero:
 ((x) * (x - 2)) = 0
 x = 0
 x = 2
 Answer
 h = (5 - x) / ((x) * (x - 2))
 x = 0
 x = 2

What is a solution to (x + 6)(x + 2) = 60?
Reika [66]

Solution of the equation (x+6)(x+2)=60 is x=4 and x=-12

Step-by-step explanation:

We need to solve the equation: (x+6)(x+2)=60

Solving:

(x+6)(x+2)=60

Multiplying terms on the left hand side

x(x+2)+6(x+2)=60

x^2+2x+6x+12=60

x^2+8x+12=60

x^2+8x+12-60=0

x^2+8x-48=0

Now factorizing:

x^2+12x-4x-48=0

x(x+12)-4(x+12)=0

(x-4)(x+12)=0

(x-4)=0\,\,and\,\,(x+12)=0

x=4\,\,and\,\,x=-12

So, solution of the equation (x+6)(x+2)=60 is x=4 and x=-12

The pentagon below has an area of 8.3 square centimeters and a side of 2.2. What is the approximate length of the apothem? A.0.4
nalin [4]

Answer:

C. 1.5 cm

Step-by-step explanation:

A pentagon is a polygon with 5 sides.  

The formula for the area of a regular polygon is

A=\frac{1}{2}ap

where a is the apothem and p is the perimeter.  The perimeter is found by multiplying the number of sides of the figure by the length of 1 of those sides:

5(2.2) = 11

Now we have everything we need to solve for the length of the apothem.  

8.3=\frac{1}{2}a(11)

Begin by multiplying both sides by 2 to get rid of the fraction, so

16.6 = 11a  Divide both sides by 11 to get

a = 1.5090909 or

C. 1.5 cm
