<em>Answer</em><em>:</em>
the surface area of the rectangular pyramid below is 300 units2
Answer:14%
Step-by-step explanation:
final grade score=a
20% of a=15
20/100 x a=15
20a/100=15
Cross multiply
20a=15 x 100
20a=1500
Divide both sides by 20
20a/20=1500/20
a=75
B% of 75=10.5
B/100 x 75=10.5
75B/100=10.5
Cross multiply
75B=10.5 x 100
75B=1050
Divide both sides by 75
75B/75=1050/75
B=14
The <em>correct answer</em> is:
Florian has the correct side lengths because the measurements fit the triangle inequality rule.
Explanation:
The triangle inequality rule states that the sum of any two sides of a triangle must be greater than the third side.
For Florian's measurements, we have:
6+8 > 10
6+10 > 8
8+10 > 6
These measurements work.
Conversely, Michelle's measurements:
7+7 = 14.
This is not greater than, so this does not work.
