Step-by-step explanation:
In m/s=( 200×1000) m/3600s
= 200000m/3600s
= 55.55m/s
Step-by-step explanation:
with 45 45 90 triangles which is what ACB is. the hypotenuse can be equalized with and the two legs have a length of x
so the side length for AB and BC is 6.
and since Triangle BCD is a 30 60 90 triangle.
the side lengths that would be corresponding would have the ratio of
x, , and 2x
so if 2x=6 x=3
then the value for x or BD is 3
Hope that helps :)
Answer:
31.4 in³
Step-by-step explanation:
The box is just big enough to hold the 3 balls, so it must have a length 6 times the radius of each ball, a width 2 times the radius, and a height 2 times the radius.
The volume of the box is:
V = (6r)(2r)(2r)
V = 24r³
The volume of the 3 balls is:
V = 3 (4/3 π r³)
V = 4πr³
So the volume of the air is:
V = 24r³ − 4πr³
V = (24 − 4π) r³
Since r = 1.4 inches:
V = (24 − 4π) (1.4 in)³
V ≈ 31.4 in³
