The plane descends, on average, 42.22 feet per second.
Given that an airplane flying at 15, 000 ft descends to land at an airport, and during the airplane's final approach it descends from 15,000 ft to 7, 400 ft in 3 min, to determine the average descent per second, the following calculation must be performed:
- (15,000 - 7,400) / (3 x 60) = X
- 7600/180 = X
- 42.22 = X
Therefore, the plane descends, on average, 42.22 feet per second.

Answer:
He jogged 4/15 of a mile farther.
Step-by-step explanation:
To find the difference between Monday and Tuesday, you have to subtract .
You can simplify this equation and make it .
Then you have to turn them into equivalent fractions with the same denominator. They can share a common denominator of 15, so the equation becomes .
Then you subtract and get .
Hope this helps!
Answer:
The single transformation that maps shape A onto shape B is a reflection across the line y = 2
Step-by-step explanation:
The coordinates of the A are A(-1, 3)
The coordinates of the corresponding point on B is (-1, 1)
Therefore, given that the x-coordinates of the pre-image A and the image B are the same, therefore, we have that image B is a reflection of image A
Also half the vertical distance between figure A and B = (3 - 1)/2 = 1
Therefore, figure A is obtained from figure B by reflection across a horizontal line, 1 unit below the lowest y-coordinate of figure A which is the line y = 3 - 1 = 2
Therefore, we have;
The single transformation that maps shape A onto shape B is a reflection across the line y = 2
Step-by-step explanation:
1..x=110/2. ( inscribed angle is half of central angle)
2..given,
in triangle DFE
angleDFE=angle DAE ( inscribed angle on same arc are equal)
angle DFE=55°
angle EDF= angle FED (base angle of isosceles triangle r equal)
now,
angle EDF+angleDFE+angle FED =180°{ sum of angle of triangle)
z+z+55=180°
2z=180-55
z=125/2
z=62.5°
3.. y=90°{ angle at circumference of circle by center is 90°}
hope it helps.
