Volume = length * height * width
= 4 qrt3 + 3 sqrt6 * w
= 12 sqrt18 w
let w = 2 sqrt50 then volume = 2*12 * sqrt 18*50 = 24*30 so this is rational
let w = 4 sqt 12 the v = 48 sqrt12 * sqrt 18 = 48 sqrt30 which is irrational
C and D are rational
answer is B
Answer:
14. m = 7/8
15 x =63
16. y= 21/2
Step-by-step explanation:
14. 7 16
---- = --------
m 2
using cross products
7 * 2 = 16 * m
14 = 16m
divide by 16
14/16 = m
simplifiy
7/8 =m
14. x 14
---- = --------
18 4
using cross products
4 * x = 18 * 14
4x = 252
divide by 4
4x/4 = 252/4
x = 63
15. 30 y
---- = --------
20 7
using cross products
30*7 = 20 y
210 = 20 y
divide by 20
210/20 =y
21/2 = y

Answer:
2995
Step-by-step explanation:
The first quartile (Q1) is defined as the middle number between the smallest number and the median of the data set
1127
1482
2995
3009
3250
3250
3445
3449
4000
6120
rearranging the data sets from the least to the highest
the middle number of the data sets is 3250
the middle number between the smallest number and the median of the data set is 2995
