Answer:
The answer to your question is: letter a
Step-by-step explanation:
data
balls diameter = 0.75 in then radius = 0.375 in
rectangular prism = length = 3 in width = 3 height = 7.5 in
Formula
Rectangular prism volume = l x w x h = 3 x 3 x 7.7 = 67.5 in³
ball volume = 4/3 (3.1416)(r³) = 4/3 (3.1416)(0.375)³ = 0.220in³
but 0.220in³ ------------------- 100 %
x ------------------- 190%
x = 0.418 in³
Finally divide the rectangular prism volume by ball volume
# of balls = 67.5 / 0.418 = 161.4 ≈ 160
Answer:
500

Hello from MrBillDoesMath!
Answer:
Choice C, 14
Discussion:
The question is a bit obtuse bust as I understand it if we take x = 14 (Choice C). determined by trial and error, then
sqrt(91x) =
sqrt ( 91 * 14) =
sqrt (1274 ) =
sqrt (49 *26) = => as sqrt(49) = 7 we can simplify the expression
= 7 sqrt(26)
Thank you,
MrB
8. 240/3 = 80 km per hour
80*4 = 320 km answer is A
9.
5.25 / 3 = 1.75 per kg answer is A.
Answer:
For this case they want to proof if the proportion of readers own a Rolls royce is less than 0.29 and that wuld be the alternative hypothesis. The complement would represent the null hypothesis. Then the system of hypothesis for this case are:
Null hypothesis: 
Alternative hypothesis:
