Answer:
384 oz per hr
Step-by-step explanation:
3 gal per hr
1gal= 128oz
3×128= 384 oz per hr
100/20=5
11×5=55
11/20 = 0.55
Answer:
2nd graph
Step-by-step explanation:
Given
f(x) = x² + 3x - 4
To find the zeros let f(x) = 0 , that is
x² + 3x - 4 = 0 ← in standard form
(x + 4)(x - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 4 = 0 ⇒ x = - 4
x - 1 = 0 ⇒ x = 1
The only graph with zeros at x = - 4 and x = 1 is the 2nd graph
The change is -(1/2 + 3/4 + 3/8).
If you add the fractions, you get -(13/8).
