Answer – TrueA design is said to have Rotational symmetry if all its characteristics remain the same after it has been rotated about an axis lying in its plane. In other words, rotational symmetry is the quality possessed by a shape has when it looks the same after it has undergone some rotation by a partial turn about an axis lying in its plane. Rotational symmetry is also referred to as radial symmetry.
In this question , it is given that a weather balloon is launched from a height of 475 feet above sea level. the balloon rises at a constant rate of 85 feet per minute.
Here we use the slope intercept form, which is

Where, y is the height h, x is the time, t. And m represents slope, which is 85.
b represents the initial height , which is 475 feet.
On substituting these values, we will get

And at t = 16 minutes, we will get

Answer:
1166.4
Step-by-step explanation:
Assuming this is the whole question, you multiply the weight of a single box by the amount in a case to find the weight of a case, hence 24.3*48 =1166.4
13/25 is greater than 7.50%.
13/25 is 50%
Hope this helps :)
