Ava finishes in 12.89 making her third.
and Savannah finishes in 12.988 seconds making her last.
The elevation represents a distance from the sea level greater than 5 feet,
because the original description specifies a distance greater than 5 feet
below sea level.
Reasons:
The elevation given as a distance is the height or distance above sea level.
In the above description, elevation is a vector, given that it has both
magnitude (distance) and direction (above sea level).
Distance is a scalar quantity, that has only a magnitude that specifies the
space covered during motion.
An elevation of less than -5 feet indicates that distance of the location
above sea level is less than -5 feet, which is the same as; the distance of
the location below sea level is greater than 5 feet.
- Less than -5 feet above sea level = Greater than 5 feet below sea level
Therefore;
- An elevation of less than -5 feet represents a distance from (below) sea level greater than 5 feet

Answer:
13421+402
Step-by-step explanation:
Answer:
5.0 ft - 5.6 ft
Step-by-step explanation:
Given that the structure is to be made using two 12 foot boards, then we expect the total perimeter to be equal to (2*12)= 24 ft.
Using the angle of elevation, 40° and the width of 8 ft then you can apply the formula for tangent of a triangle where ;
Tan α = opposite side length/adjacent length
Tan 40°= h/8
h= 8 tan 40° = 6.71 ft
Applying the cosine of an angle formula to find the length of the sliding side
Cosine β = adjacent length /hypotenuse
Cosine 40°= 8/ sliding side length
sliding side length = 8/cosine 40° =10.44 ft
Checking the perimeter = 10.44 +8+6.71= 25.15 ft
This is more than the total lengths of the boards, so you need to adjust the height as;
24 - 18.44 = 5.56 ft ,thus the height should be less or equal to 5.56 ft
h≤ 5.6 ft
