he uses 100 grams for 10 cups
20% more would be 100 *1.20 = 120 grams for 10 cups
15/10 = 1.5
120*1.5 = 180
he needs 180 grams for 15 cups.
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 simplify, the result is:
-10</span><span>±5</span>√2 (It is the last option).<span>

1) L×W 12×12=144
2) 12+12+12+12=48
3) L×W×H 5×5×5= 125
5) B×h/2 12×9=108/2=54
When the rocket accelerates up, the thrust is greater than the combined lift and drag, therefore making it go upward. Thrust from the engine / or whatever the power source is makes it lift.
Hope that helps!
