The volume of the composite figure is 145.68 cubic meters

<h3>Volume of composite figures</h3>

Composite figures are figures that is made up of more than one shape. The volume of the figure is expressed as:

Volume = volume of cylinder + volume of prism

Volume = πr²h + lwh

where

r is the radius of cylinder

h is the height

l, w and h are the length, width and height respectively

Substitute the dimensions

Volume = 3.14(2)² * 3 + (2.4*5*9)

Volume = 37.68 + 108

Volume = 145.68 cubic meters

Hence the volume of the composite figure is 145.68 cubic meters

All you have to do is look at how much sandstone Dean has and how much marble he has, then put the amount of sandstone infront of the amount of marble because in the question it says what is the ratio of sandstone to marble and you see that sandstone is first.

Hope this helps! :)

During a period of 30 working days, Deborah was late 80% of the time. How many days was she late?
erik [133]
Fairly straightforward question. She works 30 days and is late 80% or 0.8
We can model our equation
Num days late = late percentage * num working days
Basically fine portion of working days that she was late.

Num days late = 0.8 * 30=24

So Deborah was late 24 out of 30 working days. Would appreciate a brainliest

Answer:

3rd option: f(x)⇒ +∞ as x⇒-∞ and f(x)⇒ -∞ as x⇒ +∞

Step-by-step explanation:

This is a negative cubic graph, therefore:

Looking at the graph, as x goes towards negative infinity, the y values go toward positive infinity.

On the other hand, as x goes towards positive infinity, the y values go towards negative infinity.
