Answer:
The answer is B.180°.
Step-by-step explanation:
The figure is rotationally symmetric is after a rotation of a given angle, it still look the same.
In this case of a rectangle, the only way to rotate it so that is look the same, is by rotating it by multiple of 180°, so that the up and down sides flip over, as well as the right and left sides.
Therefore, the only option that applies is B.180°
The ratio 7:9 can be converted to the fraction
, which is in simplest form
Answer:
277 meters
Step-by-step explanation:
Volume of cone is 10
if the radius is r and height is h
while volume of cylinder is pi r 2nd power h,
volume of cone is 1/3 pi r 2nd power h.
hence with same r and h the volume of cone is one-third of that of cylinder and hence
volume of cone is 10.
Answer:
The solution to the graph are x = -2 and x = 2
Step-by-step explanation:
Here, we want to get the solution to the graph
As we can see, the graph is parabolic; which is a property of a quadratic polynomial
The solution refers to the value at which the graph plot crosses the x-axis
In other words, the solutions to the graph are represented by the point at which we have the graph crossing over the x-axis
We can see this happen at two points
These are the points x = -2 and x = 2
