Answer:
3x-3
Step-by-step explanation:
You have to combine like terms. <em>x</em> and 2<em>x</em> have the same variable, so this equals 3x, and then you subtract 3 so:
x-3=2x-3-x
=3x-3
24987.2 meters cubed.
Step-by-step explanation:
A Hemisphere is 1/2 of a sphere, so let's find the volume of a sphere and then cut it in half.
The volume of a sphere is V= (4/3)πr3
The diameter is double the size of the radius, so we can find r, the radius, by dividing the diameter,
45.7m, by 2. So r = 22.85 meters
so the volume of the sphere is (4/3)π(22.85 meters)3, which is 49974.35787 meters cubed.
Since we're actually looking for the Hemisphere, we can divide this volume in half to get the volume of the hemisphere as 24987.17894 meters cubed.
And because the answer must be to 1/10th of a cubic meter, that means we only want one decimal point. So we round to 24987.2 meters cubed.
The answer to this problem situation would be D.
To solve this problem you would simply divide 1 by 6 (the line between the 1 and 6 in the fraction is a division sign with the denominator always out and the numerator in)
1) 1÷6= 0.1666666666667
Now you traditionally and usually would round up but if the direction says otherwise then round down.
2) 0.17
And 0.17 would be your final answer!
