9. A small airplane is 60 miles from the airport and is going down for landing with some angle of depression. However its naviga
Svetradugi [14.3K]

Answer:

13.98 degrees

Step-by-step explanation:

Let the airplane be at point A, the airport at point B and the point of overshoot, point C.

If the plane is on path AC and the pilot wants to adjust to the path AB, the angle by which the pilot will adjust the airplane heading is the angle between AB and AC which is A.

Using Cosine Rule

Cos A=\dfrac{b^2+c^2-a^2}{2bc} \\Cos A=\dfrac{65^2+60^2-16^2}{2(65)(60)} \\Cos A=0.9704\\A=arcCos (0.9704)\\\angle A=13.98^\circ

The pilot should adjust the plane's heading by 13.98 degrees.

worty [1.4K]

Answer:

2 miles

Step-by-step explanation:

Given that :

Distance from home to store and back = 1/2 mile

In a week :

Number of times he walked from home to store and back = 1 time

Number of times she rode to store and back = 3 time

Note distance does not change whether she rode or walked:

Hence,

miles walked = 1/2 miles * 1 = 1/2 miles

Miles biked = 1/2 miles * 3 = 3/2 miles

Total Number of miles :

(1/2 + 3/2) = (1 + 3) /2 = 4/2 = 2 miles

Kendra has a painting canvas that is 22 inches wide by 38 inches high. She painted a red rose, which covered 30% of the canvas.
Wittaler [7]

<u>Given: </u>

  • Breadth of canvas is 22 inches.
  • Length of canvas is 38 inches.

<u>To Find:</u>

  • If kendra covered 30% of the canvas by painting red rose, what will be the area of canvas covered by red rose?

<u>Solution: </u>

To find the area of red rose, first we have to find the area of canvas.

★ Area of Rectangle = Length × Breadth

➝ 22 × 38

➝ 836 in²

So, Area of canvas is 836 inches².

★ Area of red rose:-

➝ 30% of 836 in²

➝ 0.30 of 836

➝ 250.8

Hence, Area covered by the red rose is <u>2</u><u>5</u><u>0</u><u>.</u><u>8</u>

<h2> ____________________</h2><h3><u>Additional</u><u> </u><u>Information:</u><u> </u></h3>

★ Triangle => ½bh

★ Rectangle => Length × Breadth

★ Circle => πr²

★ Square => Side × Side

★ Parallelogram => Base × Height

★ Sphere => 4πr²
