Answer: Apply the formula for the volume of a sphere.
Step-by-step explanation:
The volume of a sphere is
4
π
r
3
3
We just need to insert
r
=
2
c
m
into this to get the volume.
4
π
2
3

The approximate volume is
33.5103217
Answer:
30
Step-by-step explanation:
2x + x =90
3x=90
x=90/3
x is 30
Answer:
B.
Step-by-step explanation:
Plug in those x and y values into your equations.
(x, y) = (5, 1)
2x + 5y = 15
2(5) + 5(1) = 15
10 + 5 = 15
5x + 10y = 35
5(5) + 10(1) = 35
25 + 10 = 35
This proves those values are true. So the answer is B.
Answer:
The y -intercept of a graph is the point where the graph crosses the y -axis. (Because a function must pass the vertical line test , a function can have at most one y -intercept . ) The y -intercept is often referred to with just the y -value.
Step-by-step explanation:
Y - intercept represents the position of a point on y-axis or when a line passes through y-axis, it, actually, passes through a point on y-axis. And that point is called the y intercept. It is usually represented by and as a point, it is represented as.
It's called the "y intercept" and it's the y value of the point where the line intersects the y- axis. For this line, the y-intercept is "negative 1." You can find the y-intercept by looking at the graph and seeing which point crosses the y axis. This point will always have an x coordinate of zero.
Hoped this helped! :D
Answer:
Y=-5
Step-by-step explanation:
-4y on each side then -2y on each side so it is know -3=y+2. Y must be -5 because -3-2=-5
