Answer:
2294 balls is the approximate number of balls
Step-by-step explanation:
Find the volume occupied a ball of radius 3inches
Volume of a sphere=4/3 
×r³
where r is the radius in inches
4/3× ×3³ = 36
=113.11 in³
Find volume of a rectangle prism
v=l×w×h where l is length of prism, w is width of prism and h is height of prism
L=10ft=10×12=120 inches
w=5ft=5×12=60 inches
h=3ft= 3×12= 36 inches
v=120×60×36=259200 in³
Number of balls needed
N=volume occupied by a single ball/volume of the rectangular prism
N=259200/113.11 =2291.57⇒2292 balls
Step-by-step explanation:
the sequence is a geometric sequence
simply use the formula:
t(n) = a * (r)^n-1
where n = 8, a = 27, r = 4/3
Answer:
speed = distance/time
Step-by-step explanation:
The faster a sound wave travels, the more distance it will cover in the same period of time. If a sound wave were observed to travel a distance of 700 meters in 2 seconds, then the speed of the wave would be 350 m/s.
Answer: 34
Step-by-step explanation:
Answer:
(B)25
Step-by-step explanation:
From the given diagram:
are on a straight line, and we know by the Linear Postulate that the sum of angles on a straight line is 180 degrees.
Therefore:
The correct option is B.
