Answer: After 5 minutes, the plane is at 20,000 feet. It descended a total of 10,000 feet.
Step-by-step explanation:
f = feet above ground
r = rate of descent
m = minutes
f = 30000 - r · m
f = 30000 - 20000m
After five minutes:
f = 30000 - 2000(5)
f = 30000 - 10000
f = 20000

Answer:
3:5
Step-by-step explanation:
Let's create a ratio
Mushroom : Cheese
15 : 25
⬆The ratio above can be simplified
Divide both sides by 5
3 : 5
The answer is 3:5
Hope this helps :)
Have a nice day!
In a regular octagon all the interior angles are of the same value.
sum of the interior angles in octagon = (n-2) *180°
n - number of sides, in this case, n = 8
interior angles sum = (8-2)*180° = 6*180° = 1080°
since there are 8 equal angles = 1080/8 = 135°
Angle x + one interior angle of the octagon = 180 ° (as its a straight line)
x + 135 = 180
x = 45°
