Answer:
The answer is D
Step-by-step explanation:
A cant be right because the graph isn't a straight line.
B cant be right because from 0 to 60 the graph the line goes at a(n) upward slope not a straight line.
Although the first part of question c is right, the second part is wrong. From 50-90 the ling goes at a downward slope via decreasing, which isn't equal like it said so question C is wrong.
So the correct answer is D
The answer to your problem would be -60
Answer:
133
Step-by-step explanation:
The two angles add to a straight line
PQR + RQS = PQS
3x-5 + x+1 = 180
Combine like terms
4x -4 =180
Add 4 to each side
4x -4+4 = 180+4
4x =184
Divide each side by 4
4x/4 =184/4
x =46
We want to find PQR
PQR = 3x-5
= 3*46 - 5
= 138 -5
= 133
Apparently, there is a sphere inside a cylinder, and we need to find
(the volume of the cylinder) minus (the volume of the sphere).
This wouldn't be too awfully difficult if we had the measurements we need
in order to calculate the volume of the cylinder and the volume of the sphere.
You did give us a number, thank you, but no description, so we don't even know
what's 12, because we don't know how 'H' figures into anything.
If you have the numbers, here are the formulas you'll need:
Volume of a cylinder = π (radius)² (height or length)
Volume of a sphere = (4/3) π (radius)³
===============================================
Oh I think I get it. There's a little ball stuck inside a cylinder, they
both have the same radius, and the height of the cylinder is 12.
That's still not enough information to do a complete calculation.
I'm afraid we still need that radius. But we can get closer:
Volume of the cylinder = π (radius)² (12)
Volume of the sphere = (4/3) π (radius)³
(Cylinder) minus (sphere) = (4/3) π (radius²) ( 9 - radius ) .
Stuff the number for the radius into that, and you'll have the answer.
And if you need it, remember, the radius is 1/2 of the diameter.
