I think that Harry should use 1.5-2 cups of flour for his cake. It depends on the size of the cake so if its pretty small, 1.5 cups should work. If you want to take a risk, use more cups of flour.
To find the optimized value you need to find where the vertex(tip) of the parabola
use
to find the optimized x value
y= -w^2 +100w + 0
x = 50
answer: 50
I would say D) because even though it has a higher ARP but it does have a lower annual fee
The sum of the interior angles of any polygon is (n-2)*180° (n being the number of sides) so for a triangle the sum of the interior angles is 180°. The sum of the interior and exterior angles is also 180°. To work out which sets are possible you subtract each number from 180° and then add all three answers together. If you get 180° then that set of numbers is possible. Using this method, you will find that the following sets <span>can be the measures of the exterior angles of a triangle:
</span><span>120°, 110°, 130°
</span><span>120°, 120°, 120°</span>
