A prism with a base area of 5 ft² and a height of 10 ft is dilated by a factor of 65 . What is the volume of the dilated prism?
mina [271]

Answer:

The volume of the dilated prism is 86.4ft^3.

Step-by-step explanation:

The original prism has base area 5ft^2 and a height of 10ft.

The volume of the original prism is v=5\times 10=50ft^3.

The prism is dilated by a scale factor of k=\frac{6}{5}.

To find the volume of the dilated prism, we multiply the volume of the original prism by k^3=\frac{216}{125}.

V=\frac{216}{125} \times 50ft^3

\Rightarrow V=86.4ft^3

What is the solution of 4x - 30 ≥ -3x + 12?
amid [387]
First, let's add 30 to both sides:
4x - 30 +30 ≥ -3x + 12+30


4x ≥ -3x + 42

Now, let's add 3x to both sides
4x +3x ≥ -3x+3x + 42
7x ≥ 42

Let's divide both by 7:

x ≥ 6
