Answer:
f = 4d -400
Step-by-step explanation:
First, let's make some variables.
f = size of Falls Lake
d = size of Lake Drummond
d = (1/4)*f + 100
We can now rearrange the equation to find the size of Falls Lake.
d - 100 = (1/4)*f
4d - 400 = f
f = 4d - 400
Answer:
the submarine is 92.994 feet ≈ 93 feet deep from the surface of the water
Step-by-step explanation:
We can think in a triangle where the hypotenuse is the detection distance and the angle with the horizontal surface of water is the depression angle, then the underwater distance is the vertical side of the triangle.
If we denote Ф as the angle of depression ,d as the detection distance and x as the unknown depth of the submarine, using trigonometry:
x = d* sin Ф
thus
x= d * sin Ф = 238 feet * sin 23° = 92.994 feet ≈ 93 feet
Answer:
2/5 with an exponent of 3 is 8/125 or 0.064
Step-by-step explanation:
Given:
A fraction = 2/5
Exponent = 3
To find the value of the fraction using the exponent.
We know that :
⇒ 
The exponents is the number of times a number is multiplied.
So,
⇒ 
⇒ 
⇒ 
On further division the number can be written as 0.064
