525/1000 = 105/200 = 21/40
Answer:
4,200 liters
Step-by-step explanation:
The flow rate is given by:
Integrating the flow rate expression from t=0 to t=30 minutes, yields the total volume that flows out of the tank during that period:
4,200 liters of water flow from the tank during the first 30 minutes.
1. You con solve the quadratic equation x^2+20x+100=50<span> by following the proccedure below:
2. Pass the number 50 from the right member to the left member. Then you obtain:
x^2+20x+100-50=0
</span><span> x^2+20x+50=0
</span><span>
3. Then, you must apply the quadratic equation, which is:
x=(-b±√(b^2-4ac))/2a
</span><span>x^2+20x+50=0
</span><span>
a=1
b=20
c=50
4. Therefore, when you substitute the values into the quadratic equation and simplify ir, you obtain that the result is:
-10</span>±5√2 (It is the last option).
The answer would be 10 because 9+-5=4+-1=5+5=10
Answer:
32*15 = 480
1500-480 = 1020
1020/10
102 races
