Answer 1
Answer:

Answer:

D The volume of a cube increases by a factor of 8 when its edge length doubles

Step-by-step explanation:

Volume of a cube is represented by the function

V(x)=x^3

where x represents the edge length of the cube

Now when x=2x i.e., when the edge length is doubled we have

V(2x)=(2x)^3\n\Rightarrow V(2x)=8x^3\n\Rightarrow V(2x)=8(V(x))

It can be seen that the volume of the cube increased by 8 times when edge length doubles.

Solve the equation . (-2 1/7)p=-3

Answers

Answer:

p = (7)/(5)

Step-by-step explanation:

change the mixed number to an improper fraction

- 2 (1)/(7) = - (15)/(7), hence

- (15)/(7) p = - 3 ( multiply both sides by 7 )

- 15p = - 21 ( divide both sides by - 15 )

p = (-21)/(-15) = (7)/(5)



Final answer:

To solve this question, convert '-2 1/7' to an improper fraction (-15/7), then divide both sides of the equation by this value. This simplifies to p = 1.4 which is the solution.

Explanation:

In order to solve the equation (-2 1/7)p=-3, it's helpful to remember that multiplying each side of an equation by the same value does not change the solution. In this case, (-2 1/7) represents a fraction (-15/7) when converted to an improper fraction. Now, to isolate p on one side of the equation, divide both sides of the equation by (-15/7). This provides the solution: p = -3 / (-15/7), which simplifies to p = 1.4. Therefore, the solution to the equation is p = 1.4
