Answer:
2.1 m
Step-by-step explanation:
The gutter is in the shape of a cylinder.
Its volume is 20 liters and its diameter is 11 cm (0.11 m).
Its radius is half of its diameter => r = 0.055 m.
The volume in cubic metres:
1 litre = 0.001 cubic metres
20 litres = 20 * 0.001 = 0.02 cubic metres
The volume of a section of guttering is given as:
where h = length of the guttering
Therefore:
The length of the section of guttering is 2.1 m long.
Answer:
The side length of the cube is 9.
Step-by-step explanation:
To find the volume of a cube you use the equation V=E³, although edge can mean length.
Since we already know the volume though, we have to do this equation backwards, and find the cubed root of 729.
To do this we do which will give us our answer of 9 cubic inches.
Hope this helped!

Step-by-step explanation:
A.)Priscilla made a mistake when applying the horizontal shift. That "x+2" indicates a horiz. shift to the LEFT, not to the right.
Answer:
In the second step, 5 should have been distributed to both the p and the 3. To correct this, step two should say 5p+15>4p+2
If Lucas used 3/4, that means he is left with 1/4 which is what 12 is. So multiply 12*4 which equals 48. So 48-12= 36.
Lucas used 36 nails.
