Step-by-step explanation:
$72500
Answer:
1 MPH = 1.61 KMHR
Step-by-step explanation:
For an approximate result, multiply the speed value by 1.609
There are two interleaved arithmetic sequences here.
Odd terms are 5, 7, 9, 11, increasing by 2 each time.
Even terms are 1, 0, -1, decreasing by 1 each time.
The next two terms will be -2, 13.
Ok, let’s take it step by step.
Let x = number of gallons of 70% solution
100 = number of gallons of 25% solution
Then x + 100 = number of gallons of a 60% solution.
0.70x + 0.25(100) = 0.60(x + 100)
0.70x + 25 = 0.60x + 60
0.10x = 35
x = 350 gal
So, you can mix 350 gal of a 70% solution with 100 gal of a 25% solution to get 450 gallons of a 60% antifreeze solution.
