I believe its Alan, because I multiplied 5,280x21 and got 15,840 and then I divided that by 60, and got 258. 258≤1750... so Alan is you're answer
Answer: depending on what a equals
Step-by-step explanation:
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:
.87
Step-by-step explanation:
She gets 13 off so 100-13 =87
She will pay 87%
Multiply by .87
Total = Principal * (1 + rate)^years
Total = 25,000 * (1.11)^16
Total =
25,000 * <span>
<span>
<span>
5.3108943321
</span>
</span></span>Total =
<span><span><span>132,772.36
