Answer: Her measuring cup has 8.25 mL of medicine.
Step-by-step explanation:
As per given,
In 11 mL of medicine, there are 20 drops.
That means quantity in 1 drop = 
mL
Now , the quantity in 15 drops = 15 x quantity in 1 drop
= 
= 8.25 mL
Hence, her measuring cup has 8.25 mL of medicine.
Check the picture below.
so then γ ≈ 180 - 69 - 43, γ ≈ 68.
A) Height -7 = base
B) .5 * height * base = 60
Substituting A into B
B) .5 * height * (height -7) = 60
B) .5*height^2 -3.5*height = 60
B) .5*height^2 -3.5*height -60 = 0
Using the quadratic formula:
Height = 15
Subtracting 7 gives us the base length
Base = 8
**************************************************************
Double-Check
.5 * 15 * 8 = 60
24/5
I think this is the right answer, hope this help
