A: -4<br> B: -16<br> C: 15<br> D: -5
baherus [9]
The answer here is B. -16

10 + -16 equals -6 and a negative divided by a negative is a positive so -6 divided by -3 is -2.

Hope this helps!

The ground temperature at an airport was 10 degree temperature dropped 5 degrees for every 1000m above the ground. What was the
Mamont248 [21]
The ground temperature started at 10 degrees.
The rate was: for every 1000 meters (m) of going above the ground, the temperature dropped 5 degrees, meaning that it got cooler.
The ratio is 1000 meters to 5 degrees
So that would mean: 10-5-5-5-5-5=-15 degrees

The surface area of this cylinder is 1,582.56 square feet. What is the height?
Leno4ka [110]
<h3>What's the height of a cylinder formula?</h3>

There are five basic equations which completely describe the cylinder with given radius r and height h:

  1. Volume of a cylinder: V = π * r² * h,
  2. Base surface area of a cylinder: A_b = 2 * π * r²,
  3. Lateral surface area of a cylinder: A_l = 2 * π * r * h,
  4. Total surface area of a cylinder: A = A_b + A_l,
  5. Longest diagonal of a cylinder: d² = 4 * r² + h².

Sometimes, however, we have a different set of parameters. With this height of a cylinder calculator you can now quickly use ten various height of a cylinder formulas which can be derived directly from the above equations:

  1. Given radius and volume: h = V / (π * r²),
  2. Given radius and lateral area: h = A_l / (2 * π * r),
  3. Given radius and total area: h = (A - 2 * π * r²) / (2 * π * r),
  4. Given radius and longest diagonal: h = √(d² - 4 * r²),
  5. Given volume and base area: h = 2 * V / A_b,
  6. Given volume and lateral area: h = A_l² / (4 * π * V),
  7. Given base area and lateral area: h = √(A_l² / (2 * π * A_b)),
  8. Given base area and total area: h = (A - A_b) / √(2 * A_b * π),
  9. Given base area and diagonal: h = √(d² - 2 * A_b / π),
  10. Given lateral area and total area: h = A_l / √(2 * π * (A - A_l)).
