It's ....c 8000 lbs because there is 2000 lbs in a ton so you do 4x2 which equals 8 then you add your 3 zeros. Hope I was able to help.
The angles are complementary.
This means they add to 90 degrees.
(2x + 1) + (x + 5) = 90.
3x + 6 = 90. (Combine like terms)
3x = 84. (Subtract 6 from each side)
x = 28. (Divide 3 from each side)
x = 28
D is correct
Substitute everything in first
3(-2)-1-3(-2)
Then simplify
-6-1+6 = -1
The answer is -1
Answer:
Step-by-step explanation:
The formula for the volume of a sphere is
In order to use this formula we have to have a value for the radius and right now we don't. But we can find it indirectly by using the circumference formula. The circumference formula is
If the circumference is 20π, then we will fill that in for "C" and solve for r:
20π = 2πr and if you divide both sides by 2π, you'll get that r = 10. Now we have a radius.
Using that in the volume formula:
and then simplifying a bit:
and
which divides to give you
, third choice down.
