Answer:

The volume is 8^3 = 512 cm^3, and the mass is 1,536g. So the density is 1,536/512 = 0.003 g/cm^3. (Note that the number of significant digits should be 1, as 8 cm being the side length of the cube is in one significant digit.)

Kyle’s bank statement shows a balance of –$18.50. Which describes the magnitude, or size, of the debt in dollars?
oksano4ka [1.4K]

Answer:

C. $18.50.

Step-by-step explanation:

We have been given that Kyle’s bank statement shows a balance of –$18.50. We are asked to determine the magnitude, or size, of the debt in dollars.

We know that the magnitude of a negative number is absolute value of negative number.

\text{Magnitude of debt in dollars}=|-\$18.50|

Since absolute value of a negative number is opposite of the number.

\text{Magnitude of debt in dollars}=-(-\$18.50)=\$18.50

Therefore, option C is the correct choice.

P = 4s

s = 1/4P

Please help me find the value of x with all the work
iVinArrow [24]

Answer:

x = 21

Step-by-step explanation:

the angles 5x - 35 and 3x + 7 are vertical angles and congruent, thus

5x - 35 = 3x + 7 ( subtract 3x from both sides )

2x - 35 = 7 ( add 35 to both sides )

2x = 42 ( divide both sides by 2 )

x = 21
