He surface area of a piece of paper is 692 cm2. Use the fact that 10 mm = 1 cm to convert this area to mm2. Give your answer as
spin [16.1K]

Answer:

Surface area = 6.92 cm²

Step-by-step explanation:

<u>Given the following data;</u>

Surface area = 692 cm²

To convert the area in cm² to mm²;

<u>Conversion:</u>

10 mm to cm = 10/10 = 1 cm

1 mm² to cm² = 1/100 = 0.01 cm²

692 mm² to cm² = 692 * 0.01 = 6.92 cm²

Therefore;

692 mm² = 6.92 cm²

<em>In conclusion, the surface area of the piece of paper is 6.92 square centimeters.</em>

How many solutions are there if m &lt; 0 and p &gt; k ? <br><br><br><br> p + m| x + n| = k
neonofarm [45]

9514 1404 393

Answer:

  2

Step-by-step explanation:

The solutions are ...

  p +m|x +n| = k . . . . . given

  m|x +n| = k -p . . . . . . subtract p

  |x +n| = (k -p)/m = (p -k)/-m . . . . . . must have (p-k)/-m ≥ 0

  x = -n ± (p -k)/-m

For the given conditions, m < 0, p > k, we are guaranteed that (p-k)/-m > 0, so there are 2 solutions.

The amount of oil used by a ship traveling at a uniform speed varies jointly with the distance and the square of the speed. The
frosja888 [35]

Answer:

Step-by-step explanation:

Joint variation has the equation

y = kxz

k is the constant of variation and needs to be solved for using the initial conditions, then filled in later to another equation related to the given info to solve for something else.  We are given y = amount of oil used, x = distance traveled, z-squared is the speed.  Our equation looks like this, to be exact:

y=kxz^2

Filling in with the initial conditions:

34=k(60)(20)^2 which gives us the

k = .0014166667

Now we need to find the amount of oil used, y, under other circumstances, but this time we have our k.

y=(.0014166667)(32)(23)^2

which gives us that the amount of oil used, when rounded to the tenths,

y = 24.0 barrels
