Answer:
5.12 minutes ≈ 5 minutes 7.2 seconds
Step-by-step explanation:
The flight path of the airplane is along the line ...
y = -125/135x = -25/27x
The perpendicular line through Mt. Rainier's location is ...
y = 27/25(x -56) -40
In standard form, these two equations are ...
- 25x +27y = 0
- 27x -25y = 2512
The point of closest approach has the coordinates that are the solution to these two equations:
(x, y) = (33912/677, 31400/677)
The distance d from the origin to this point is given by the Pythagorean theorem (distance formula) as ...
d = 1256√(2/677) . . . . . km
This distance can be converted to time using the speed of the airplane:
5.12 minutes after departing JBLM you will be closest to Mt. Rainier.

Answer:
A
Step-by-step explanation:
The right answer is Option B and Option E.
Step-by-step explanation:
Given value is;
2% of 90.
Percent can also be written fraction form, therefore, we can write it as;
If we divide the 2 the by 100, then it would become,
Therefore,
and 0.02*90 have same value as 2% of 90.
The right answer is Option B and Option E.

He went around 24 times and 4 times is a mile so 24/4 will tell us how many miles he biked. He biked 6 miles in thirty minutes. The formula distance = rate(time) will tell you how fast he is going.
6 = r(1/2) divide each side by 1/2 (The time has to be in hours)
12 = r
So he was going 12 miles an hour.
Answer:
132+180+ 168=480
Step-by-step explanation:
3/8 of 480= 180 (tuna)
35% of 480=168 (beef)
ratio is 132 (ham)
and adds up to 480
