Answer:
5√3 miles per hour
Step-by-step explanation:
Throughout their journey, the component of velocity of rowboat B to the east is the same as that of rowboat A:
(10 mph)(cos(π/3)) = 5 mph
Meanwhile, the component of velocity of rowboat B to the north is ...
(10 mph)(sin(π/3)) = 5√3 mph
Since rowboat A is always traveling in a direction that is at right angles to the direction between the boats, it contributes nothing to their relative speed. Since rowboat B is always directly north of rowboat A, its speed to the north is their relative speed.
The distance between the rowboats is increasing at 5√3 mph ≈ 8.66 mph.
Let
3x----> angle exterior 1
4x----> angle exterior 2
5x----> angle exterior 3
we know that
The exterior angles of any polygon add up to 360 degrees
so
3x+4x+5x=360-------> 12x=360----------> x=30°
The largest of exterior angles is equal to the smallest of interior angles
so
the largest of exterior angles is 5x------> 5*30=150°
the smallest of interior angles is 180°-150°=30°
therefore
the answer is
the smallest of interior angle measure 30 degrees
Answer:
15 dollars.
Step-by-step explanation:
That would be 60% of 25
= 25 * 0.6
= 15 dollars.
Answer:
It will take 22.5 minutes to complete 1 mile
Step-by-step explanation:
From the question,
The marching band walks 1/15 miles in 1.5 minutes
First we will determine the miles cover in 1 minute
If the marching band walks 1/15 miles in 1.5 minutes
then, they will cover
miles in 1 minute

Then,

miles
∴ 2/45 miles are covered in 1 minute
Now,
If 2/45 miles are covered in 1 minute
Then, 1 mile will be covered in
minute


∴ 
Hence, it will take 22.5 minutes to complete 1 mile
