Answer:
x ≥ 4
Step-by-step explanation:
Since there is a closed circle at x = 4, this indicates that x can be equal to 4
The line to the right is shaded indicating values of x greater than 4
Thus x ≥ 4 ← is the inequality represented in the number line
11 is your answer because 11* 11 is 121
C.24 is supplementary to 7
Answer:
Volume = 144 ft
Step-by-step explanation:
1. Let's write some things down, so we don't forget them!
Length = 12 ft
Height = 2 ft
Width = 6 ft
2. We can probably assume the sandbox is a rectangle. The formula for the volume of a rectangle is Length x Height x Width. So, 12 x 2 x 6 = 144, therefore that's the volume!
Answer:

Step-by-step explanation:
the formula for density is:

where d is density, m is mass, and V is volume.
solving for m in the last equation:

so if we find the volume and multiply it by the density
we will get the mass of the object.
The volume of a rectangular prism is given by:

where
is length,
is width and
is height:

we substitute to find the volume:

since the density has units of
we need the volume also in units of
, so we make the conversion using:

multiplying by 30:

and now we find the mass with the equation:

substituting d and V:

the nearest gram is:
