Answer:
80 units
Step-by-step explanation:
v = 1/3 bh
v₁ = 1/3 * b * h₁ = 344
v₂ = 1/3 * b * h₂ = 301
v₁ / v₂ = h₁ / h₂ = 344 / 301
h₂ = h₁ - 10
h₁ / (h₁ - 10) = 344 / 301
344 * (h₁ - 10) = 301 * h₁
344* h₁ - 3440 = 301 * h₁
43 * h₁ = 3440
h₁ = 80
You pretty much just flip the second fraction and factor

Answer:
C
Step-by-step explanation:
you add 15 and 10 witch gets you 25 and then you add 3 for the students that don't play either witch gets you 28 and then subtract 28 from 32, or just count up from 28 to 32 but you get the same answer.
She has 6 1/3. The larger dress need 3 2/3. So 6 1/3 - 3 2/3 = 2 2/3
So Mrs. Rodriguez will need 2 2/3 for the smaller dress
