Answer:
13 l of 15%, 13 l of 25%, 26 l of 70%
Step-by-step explanation:
solutions:
final solution:
This includes 0.45*52l= 23.4 l acid
Let's assume:
- amount of 15% solution= x
- amount of 25% solution= y
- amount of 70% solution= z
- and we have z=2y
so there are 2 equation:
or
- x+y+2y= 52 ⇒ x+3y= 52 ⇒ x= 52- 3y
- 0.15x+1.65y=23.4
- 0.15*(52-3y)+1.65y=23.4
- 7.8-0.45y+1.65y=23.4
- 1.2y=23.4-7.8
- 1.2y= 15.6
--------
- x= 52- 3*13= 13 l
- z= 2y= 2*13= 26 l
Answer:
21.4 units
Step-by-step explanation:
Greater angle: 180 - 80 = 100
diagonal² = 14² + 14² - 2(14)(14)cos(100)
diagonal² = 460.0700856454
diagonal = 21.4492444073
20 miles a gallon? 120 divided by 6
Answer:1/3
Step-by-step explanation:
3-2 2/3 its easy because if you have 3 wholes and then only 2 2/3 of that is being taken away then you have 1/3 of 3 left over
