Answer:
Height of the goalpost is 9.25 m.
Step-by-step explanation:
As per the rule of reflection in physics,
Angle of incidence = Angle of reflection
As we can see in the picture attached, both the angles (θ) are equal.
m∠ACB = m∠ECD = 90° - θ
m∠ABC = m∠ADC = 90°
Therefore, both the triangles ΔABC and ΔEDC will be similar.
And by the property of similar triangles, their corresponding sides will be proportional.


ED = 
ED = 9.25 m
Height of the goalpost is 9.25 m.
Answer:
The correct unit price would be $1.23.
The contractor divided 103.32 by 7, resulting in an error.
Step-by-step explanation:
If we know a dozen equals 12, then 7 dozen looks like:

Multiply.

Now we know the contractor purchases 84 pairs of padded work gloves.
Let's find our unit price:
<em>unit price =</em> 
Substitute.
<em>unit price = </em>
Divide.
<em>unit price = </em>
<em />
<em>__</em>
To find the error of the contractor, let's try substituting in a number (7) provided in the question to see if we get $14.76 per pair:

Divide.
