Answer: 228 Feet
Step-by-step explanation: 271 feet - 43 feet = 228 feet descended.
Value of an expression 8<span>3
</span>in where 8 is the base number and 3 is the exponent.
To get the answer, simply multiply the base number as many times as the exponent says.
Since the exponent is 3 and base is 8, we need to multiply 8 three times.
=> 8 x 8 x 8
<span>=> 512 </span>
Thus, the value of the given equation 83 is equals to 512
to check if our answer is correct, simply divide 512 by 8 twice.
<span>=> 512 / 8 </span>
=> 62 / 8
<span>=> 8</span>
We know that
The arrangement forms an isosceles triangle with equal legs of 8 miles.
The angle between the legs is equal to

°
Therefore, the other two angles are
Angles = (180-60)/2 = 120/2 = 60°
It can, therefore, be noted that all angles are equal and thus the resulting triangle is actually an equilateral triangle and thus all the sides are equal.
Hence
the answer is
the distance between the two ships is 8 miles apart
alternative Method
Applying the law of cosines
<span>c²=a²+b²-2*a*b*cos C
</span>where
a=8 miles
b=8 miles
C is the angle between the legs-------> 123-63------> 60 degrees
c is the distance between the two ships
so
c²=8²+8²-2*8*8*cos 60------> c²=64-------> c=√64------> c=8 miles
Answer:

What is 2/5 * 7/10
7/10 x 2/5 = 7/25
Step-by-step explanation:
As you Can See Here I have Explained how to Multiply Fraction.
we multiply two fractions, such as 7/10 x 2/5, we simply multiply the numerators by each other and the denominators by each other.
To multiply the two fractions, first multiply the top numbers by each other, then multiply the bottom numbers by each other,
___________________________________________________________
7/10 and 2/5 = ?
1. Multiply both numerators
7 x 2 = 14
2. Multiply both denominators
10 x 5 = 50
Which Equals 14/50
14/50 is an equivalent fraction for 7/10 times of 2/5, and its simplified term is 7/25.
Therefore Making the Answer 7/25.
