If the mass of a material is 43 grams and the volume of the material is 12 cm^3 what would the density of the material be

1 answer:

7 0

Here, we have,
Mass = 43 g
Volume = 12 cm^3
Density = ?
Using Formula,
Mass = Density * Volume
=> 43 g = Density * 12 cm^3
=> Density = 43/12 g/cm^3
=> Density = 3.58333 g/cm^3

Solve the compound inequality 4x – 7 > 5 or 5x + 4 ≤ –6

bija089 [108]

Answer:

inequality form: x $\leq$ -2 or x > 3

interval notation form: (-∞,-2] ∪ (3,∞)

Step-by-step explanation:

I attached a picture that shows all the work. You begin by isolating then solving for x on both sides. Then form a solution using the information found out about x. For example, you can combine the found inequalities for x to solve that x must be GREATER than 3 while being LESS than -2. Using that you can form an line and make a line. Remember, when writing in interval notation form you always begin from the left to the right (in reference) to the number line.
