Find the volume of 20m, 5m, 18m
HACTEHA [7]

Answer:

600 m³

Step-by-step explanation:

The shape we have is a rectangular pyramid:

Formula:<u><em> (volume of a rectangular pyramid)</em></u>

Volume = (1/3) × Base Area × height

___________________________

In our case :

Base area = L × W = 20 × 18 = 360 m²

height = 5 m

⇒ Volume = (1/3) × Base Area × height

    \Longrightarrow \text{volume} \  =\  \frac{1}{3} \times 360\times 5

\Longrightarrow \  \text{volume} \  =\  600\  m^{3}

What is the solution if the inequality shown below? a+2&lt;-10​
daser333 [38]

Answer:

a < -12

Step-by-step explanation:

Isolate the variable, a. Treat the < as a equal sign, what you do to one side, you do to the other. Subtract 2 from both sides:

a + 2 < -10

a + 2 (-2) < -10 (-2)

Simplify:

a < -10 - 2

a < -12

a < -12 is your answer.
