Step-by-step explanation:
dₙ = -5 (1/2)n-1
the 3rd term in the sequence means n = 3
d₃ = -5(1/2)(3-1) = -5(1/2)(2) = -5

an isosceles triangle is a triangle with two twin sides, and therefore two twin angles.
if one angle is 98°, well, we can't have another 98° angle because that makes 98+98 = 196°, and the sum of all interior angles in a triangle cannot be more than 180°.
so the other remaining angles must be the twin smaller angles, namely 180 - 98 = 82, and each twin takes half of that, namely 41°.
Check the picture below.
The second day, she sold more.
We know 7/9 is about 0.777777777778
And 0.78 < 0.85
So the second day she sold more.
All of the disks = 100%.
40% are red.
2/5 = 40/100 = 40% are yellow.
40% + 40% = 80%
100% - 80% = 20%
20% of the disks are blue.
20% can also be written as 20/100, which simplifies to 1/5.
1/5 of the disks are blue.
