Answer:
The answer can be calculated by doing the following steps;
Step-by-step explanation:
Part A.
We are given the total volume of the amount of sand she will want to fill
we are also given the shape and dimensions of the cylinders
Total volume of the sand = 1,000
Cylinder= radius 4 in, and height 8 in
the volume of a cylinder is V=πr^2h
We will solve for the volume of the cylinders
V=πr^2hV=π(4)^2*(10)
V = π (16) * (10)
V = π 160
The volume of the cylinders she wants to fill is 502.65 in^3
How many cylinders will she need
Well,
1000/502.65 <span>≈ 1.98
She will need two cylinder cans to fill with the 1,000 in^3 of sand
Part B.
To see if this is true, we find the half of the original cylinder's radius and height then solve for the volume and compare
</span>V=πr^2h
<span>The height and radius of the original cylinders were 4 r and 8h
we will find half of that which will be : 2 r and 4 h
Now solve for the volume </span>V=πr^2h
V=π(2)^2* (4)
V=π (4)*(4)
V = π 16
V ≈<span> 50.26 inches ^3
The volume of the original cylinders was </span>502.65 in^3 and the volume of the new cylinders is 50.26 in^3... Clearly the volume of the new cylinders is NOT half of the original. Sally is not correct!

The answer is 1230.93
The hundredth position is 0.0<span>0
</span>So, in 1230.932567, the hundredth position is 1230.93
Answer: 500 investigated @ 12%, 1,000 @ 13%, 1,500 @ 14%.
Process:
Suppose $x investigated at 12%, $y @ 13%, $(x+y) @ 14%.
According to the question we can set up the equations:
x+y+x+y=3000
0.12x+0.13y+0.14(x+y)=400
Solve it: x=500, y=1,000.
So x+y=1,500.
Answer: I don't know if this is correct
Step-by-step explanation:
With ECDIS as the primary source of navigation, the Navigating Officer can plan and summarise the passage much faster than on Paper Charts.
This is the setting which will sound an alarm if the vessel is within the limit specified.
Shallow Contour: This setting indicates the non-navigable area and marks the boundary outside of which the vessel may safely navigate.
