Answer: 4th option

Explanation:

x = 2/3 • pi • r^3
x divide by 2/3 = pi • r^3
x • 3/2 = pi • r^3
3x/2 = pi • r^3
3x/2 divide by pi = r^3
3x/2 • 1/pi = r^3
3x/2(pi) = r^3
Cube root(3x/2(pi)) = r

600 is 10 times as much as what please help me!!!!
djyliett [7]
We can create such equation to solve your problem
10*x=600
where x is variable which we want to know.
To solve this we can just divide 600 by 10 to see what the number we want.
600:10=60
The result is 60

Write the slope-intercept form of the equation of the line parallel to the
ozzi

Answer:

<h2>           y = -2x + 1 </h2>

Step-by-step explanation:

2x + y = 5       ← given line

2x + y = C      ← any parallel line

The line passing through (0, 1), therefore:

2×0 + 1 = C

C = 1

2x + y = 1    ←  the parallel line that passes through (0, 1)

To change it to slope-intercept form we just need to subtract 2x from both sides:

y = -2x + 1

Determine if segment XY is tangent to circle Z.
GrogVix [38]

Answer:

It is not.

Step-by-step explanation:

For XY to be a tangent XY must be perpendicular to radius at point of contact with circle (X).

Perpendicular also means 90° angle between XY and radius.

90° angle means XYZ should be a right angled triangle

Test for right angle triangle: pythagoras theorem.

3.6²+2.7²≠1.8²

Hence not right angled. XY not a tangent.
