He have to buy 4 bags to put all the dirt at once.
Step-by-step explanation:
Radius = 17 inches
Height = 28 inches
Volume of dirt from the cylindrical hole = π(r x r) h
= π(17 x 17) 28
= (3.14) (289) 28
= 25408.88 cubic inches
1 foot = 12 inches
Volume of dirt the bag can hold= 24 x 18 x 48
= 20736 cubic inches of dirt
The man fills only one third of the bag.
The volume of dirt the man fills = (1/3)20736
= 6912 cubic inches
Total bags = 25408.88/6912
= 3.69
= appx. 4 bags
He have to buy 4 bags to put all the dirt at once.
Answer:
60 squared feet
Step-by-step explanation:
Take in the formula of a half multiplied by the base and the height

<h3>How to graph a quadratic function </h3>
To graph a parabola, we shall follow the following procedure:
- Mark the vertex of the parabola on the <em>Cartesian</em> plane.
- Mark at least two pairs of values on the <em>Cartesian</em> plane, one on the right of the vertex and other on the left of the vertex.
- Match the points to create the resulting curves.
By following all the steps, we generate the curve with the help of a graphing tool.

The rule is:
(a^b)^c=a^(b*c)
In this case:
(9^3)^4=9^(3*4)=9^12
and if you wanted it more simplified you could say:
9^12=(3^2)^12=3^(2*12)=3^24
