Step-by-step explanation:
11mg_6.5mg=4.5mg
in 24mins 4.5mgwas gone.
6.5mg_2mg=4.5mg
you have to lose 4.5mg more
answer 24+ 24
48 minutes

Answer:
109
Step-by-step explanation:
every straight line equals 180 so the sum of the angles should add up to 180
180-71= 109
side note- interior angles add up to 180
One way to locate the vertex is to obtain the coefficients a, b and c from the quadratic and then calculate
-(-16)
x = -b / (2a). Here, x = ---------- = -2
2(-4)
Next, evaluate y at x = -2: y = -4(-2)^2 - 16(-2) - 12 = -16 + 32 - 12
y = 4
the vertex is at (-2,4).
