Given that a certain shade of pink is created by adding 3 cups of red paint with 7 cups of white paint.
That means ratio of red paint and white paint must 3:7 .
Let x be the amount of red paint cups for 1 cup of white paint.
Then ratio of red paint to white paint is
Hence cups of red paint is needed for 1 cup of white paint.
The number in "?" is or 0.04286 cups.
The height of the ramp above the ground from its highest end is 7.9 inches.
<h3>What is height?</h3>
Height is the vertical distance between two points.
To calculate the height of the ramp above the ground, we use the formula below.
Formula:
- h = Lsin∅............. Equation 1
Where:
- h = Height of the ramp above the ground
- L = Length of the fiberboard
- ∅ = Angle of elevation from the ground
From the question,
Given:
Substitute these values into equation 1
- h = 27×sin17°
- h = 7.89
- h ≈ 7.9 inches
Hence, the height of the ramp above the ground is 7.9 inches.
