Answer:
8 and a half hours
Step-by-step explanation:
Time arthur went to bed = 9:30 pm
Time arthur woke up = 6 am
Hours arthur was asleep = 24 - (9 and half + 6)
= 24 - 15 and a half
= 8 and a half
Answer:
f(x) = 4x² + 9x - 28
Step-by-step explanation:
Create the polynomial by multiplying (4x - 7) and (x + 4) together:
f(x) = 4x² + 16x - 7x - 28, or
f(x) = 4x² + 9x - 28
Next time, please share the given answer choices. Thanks.
The answer is B its quite easy if you look at it

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.
