Answer: 9 meters

Step-by-step explanation:

A line between two opposite corners splits the floor into two right angled triangles, therefore we can use Pythagoras’ Theorem which is:

a^2 + b^2 = c^2

where c is the hypotenuse, and a and b are the other two sides.

Hypotenuse in this question is 15 metres while one side is 12 metres. The length will now be:

a^2 + b^2 = c^2

12^2 + b^2 = 15^2

b^2 = 15^2 - 12^2

b^2 = 225 - 144

b^2 = 81

b = ✓81

b = 9m

The length of the storage unit is 9m

Solve the triangle. Round lengths to the nearest tenth and angle measures to the nearest degree. B = 15° C = 113° b = 49
VMariaS [17]

Answer:

  A = 52°, a = 149.2, c = 174.3

Step-by-step explanation:

Technology is useful for this. Many graphing calculators can solve triangles for you. The attachment shows a phone app that does this, too.

___

The Law of Sines can give you the value of c, so you can choose the correct answer from those offered.

  c = sin(C)·b/sin(B) = sin(113°)·49/sin(15°) ≈ 174.271 ≈ 174.3 . . . . . third choice

The Beechcraft 1900D is a commuter airplane with a fuel capacity of 665 gallons. The function that represents how the amount of
nalin [4]

Given:

The  function that represents how the amount of fuel changes as a function of distance flown is

f(x)=-0.9x+665

where x represents miles flown, and f(x) represents the amount of fuel remaining.

To find:

The rate of change for this scenario.

Solution:

The slope intercept form of a linear function is

y=mx+b        ...(i)

Where, m is the slope or rate of change and b is the y-intercept.

We have,

f(x)=-0.9x+665        ...(ii)

On comparing (i) and (ii), we get

m=-0.9

Therefore, the rate of change for this scenario is -0.9. It means, the amount of fuel in the airplane is decreasing by 0.9 gallons per mile.
