The density of a certain material is such that it weighs 10 ounces per gallon of volume. Express this density in pounds per pint

poizon [28]

Answer:

0.08 pounds per pint.

Step-by-step explanation:

Given: The density of a certain material is such that it weighs 10 ounces per gallon.

We are to express this density in pounds per pint.

1 gallon ⇒ 10 ounces

1 pound = 16 ounces

How many pounds? = 10 ounces.

Cross-multiplying gives;

$\frac{10 * 1}{16} = 0.625$ pounds

1 gallon = 8 pints

The density in pounds per pint is;

0.625 pounds ÷ 8 pints = 0.078125 pounds per pint = 0.08 pounds per pint (answer rounded up to the nearest hundredth).

If f(x) = x^3 - 2x^2 , which expression is equivalent to ff(i)?

kkurt [141]

$i=\sqrt{-1}\to i^2=-1\\\\f(x)=x^3-2x^2\\\\f(i)=i^3-2(i^2)=i\cdot i^2-2(-1)=i(-1)+2=2-i$
