Answer:
- 35 grams of 11.43% solution
Step-by-step explanation:
The end solution has same volume as initial volumes of mixture.
The concentration of solution is calculated as below
- 10*0.15 + 25*0.1 = 4 g
- 4 / 35*100% = 11.43% (rounded)
Answer:∠1 and ∠5
Step-by-step explanation:
(A) ∠3 and ∠6 forms the interior angles on the same side of the transversal. Thus, this option is incorrect.
(B) ∠1 and ∠4 forms the linear pair on the straight line a, thus this option is incorrect.
(C) ∠1 and ∠5 forms the corresponding angle pair, thus this option is correct.
(D) ∠6 and ∠7 forms the linear pair on the straight line a, thus this option is incorrect.
Arrange in ascending order:-
6 7 11 13 14 15 15 19 21
median = 14
lower quartile = mean of 7 and 11 = 9
upper quatile = mean of 15 and 19 = 17
Interquartile range = 17 - 9 = 8
answer is 8
Answer:
160
Step-by-step explanation:
4 is too low, 90 cant be divided by 8 and 160 is the only answer even though it is highest number
