Answer:
Given the mass of the object = 15g
Given the volume of the object = 3 mL
Density = ?
Step-by-step explanation:
We have two values of an object that is mass of the object and volume of the object. Now we are required to find the Density of the object. In order to find the density of the object, we have to divide the given mass with the given volume. Below is the calculation of the density.
Density = Mass / Volume
Density = 15g / 3 mL
Density = 5 g/ml
The answer would be $24.55 per oz of gold alloy so rounded up would be $25
Answer:
B.
Step-by-step explanation:
Area is width times height.
(5p-7)(3p+4)
Multiply using FOIL method
(First, outer, inner, last)
(5p*3p) + (5p*4) + (-7*3p) + (-7*4) =
15p² + 20p -21p - 28 =
15p²-p -28 =
B is the closest one. They might have made a typo.
