Answer:
The Average Speed of the Ball is 3.925 m/s
Step-by-step explanation:
Add All The Numbers Together
0.2+0.5+5+10
Divide By How Many Measurements There Are
And There Are 4 Measurements
15.7/4 = 3.925
Answer:
Step-by-step explanation:
slant height = l = 15 mm
radius = r = 7 mm
Surface area of cone = πr (l + r) square units
= 3.14 * 7 *(15 + 7)
= 3.14 * 7 * 22
= 483.56 square mm
Answer:
<em>1</em>
Step-by-step explanation:
It only has 1 symmetry line. It's the line that connects the vertex of the vertex angle of the triangle to the midpoint of the base of the triangle.
Answer:
x = 3
Step-by-step explanation:
In a 30-60-90 triangle the side between 60 and 90 degree angle is a, the side between 30 and 90 degree angle is a√3, and the hypotenuse is 2*a.
Given that the side that is supposed to be a is currently √3, we know that the missing side x must be:
a√3 (We know that a, in this case, is √3, so substitute)
x = (√3) * (√3)
x = 3
