Answer:
3/2
Step-by-step explanation:
rise/run
65. It is a pythagorean triple if you divide the numbers by 5
this can be solved by establishing system of
eqution:
let x be the amount of 25 % acid soln needs to
be drained
y is the amount of 70% acid solution
first equation:
<span>(100 – x) + y
= 100</span>
Second equation
0.25(100 – x ) + 0.7y = 0.60(100)
Solving the system of equation
<span>X = 77.78 g of 25 % acid solution is needed to
be drained</span>
The original price is $500.
The new price with the payment plan is $560.
The percent change equation is shown in the picture.
First we find the difference or the amount of change.
560-500= 60.
To find the percent we divide 60 (the amount of change) over 500, the original amount.
60/500= 0.12.
0.12 as a percent is 12%
The answer is B. 12%
