40 cents, divide 20 by .05
Answer: V= 750
Step-by-step explanation: The formula for the volume of a rectangular prism is given as: Volume of a rectangular prism = (length x width x height) cubic units. So try The length, width, and height of a rectangular prism are 15 cm, 10 cm, and 5 cm, respectively.
To find the inverse of a function, stick a y for the f(x).
So, f(x) = 4x + 12 becomes y = 4x + 12
Then switch the x and y.
So, y = 4x + 12 becomes x = 4y + 12
Then solve for y.
x = 4y + 12
x - 4y = 12 <-- Subtract both sides by 4y
-4y = 12 - x <-- Subtract both sides by x
y =

So, the inverse of f(x) is g(x) = -3 + x/4.
Answer:
Step-by-step explanation:
Triangle IJK is a right angle triangle.
From the given right angle triangle
JK represents the hypotenuse of the right angle triangle.
With ∠K as the reference angle,
IK represents the adjacent side of the right angle triangle.
IJ represents the opposite side of the right angle triangle.
To determine Cos K, we would apply trigonometric ratio
Cos θ = adjacent side/hypotenuse. Therefore,
Cos K = 36/85
Cos K = 0.4235
Rounding up to the nearest hundredth,
Cos K = 0.42
Answer is 4.
Right angle= 90
50+ 10(4)= 90
