Answer:Here are some more problems to solve.

Calculate the volume of a paperback book with the following dimensions:

Length = 12 cm

Width = 3 cm

Height = 20 cm

Calculate the volume of a steel bar with the following dimensions:

Length = 5 cm

Width = 2 cm

Height = 30 cm

Now determine the density of the steel bar if its mass is 2.34 kg. (Hint: Convert to grams first.)

A cork has a volume of 5.0 cm3 and a mass of 1.2 grams. Calculate its density.

Water has a density of 1 g/cm3. If you placed a cork and a steel paper clip in a jar of water, what do you think would happen? Use your knowledge of density to explain the outcome.

What is the parallel line and slope of a perpendicular like for 3x+5y=4
jonny [76]

Answer:

a line parallel has the same slope and different y-intercept, and the slope of the perpendicular line would be -3/5

Step-by-step explanation:

3x + 5y = 4

5y = -3x + 4

y = -3/5x + 4/5

Solve x^2 - x - 5/2 = 0 using the quadratic formula.
Soloha48 [4]
Using the quadratic formula, we have:

\frac{1+- \sqrt{11} }{2}, so our solutions are \frac{1+ \sqrt{11} }{2} and \frac{1- \sqrt{11} }{2}.

Through (-4,6) and parallel to y=-3x+4
liraira [26]
Y=mx+b
parallel lines will have the same slope.

using the points (-4,6) and the slope for the parallel line -3 we can find b (the y intercept) for the line.

6 = (-3)(-4) + b
6 = 12 + b
-12 + 6 = -12 + 12 +b
-6 = b
so the line that runs through points (-4,6) and parallel to y= -3x+4 is:
y = -3x -6
