Answer:
x=1
Step-by-step explanation:
1) (-4) + (-9) = -13
2) 5 + (-12) = -7
3) -6 + 5 = -1
4) -7 + 7 = 0
<span>5) -7 + 2 ___ 3 + (-9)
- 5 ____ - 6
</span>-7 + 2 > 3 + (-9)
6) <span>4 + (-8) ___ 6 + (-8) + (-6)
- 4 ____ - 8
</span><span>4 + (-8) > 6 + (-8) + (-6)
7) </span><span>$66
8) </span><span>-$12

Answer:
Approximately 67.348 litres can be put in six hemispherical bowl with a diameter of 35 centimetres.
Step-by-step explanation:
The volume of a hemisphere (
), measured in cubic centimetres, is obtained from this formula:

Where
is the radius of the hemisphere, measured in centimetres.
We know that radius is the half of the diameter (
), measured in centimetres, then:

(
)


Now, we get the volume of each hemispherical bowl:


The total volume of six hemispherical bowl is:



From Physics we know that 1 litre equals 1000 cubic centimetres. Then:

Approximately 67.348 litres can be put in six hemispherical bowl with a diameter of 35 centimetres.
