Answer:
320cm.²
Step-by-step explanation:
= 5
2 + 2[5] = 96 ↷
2 + 10 = 96 ↷
12 = 96 ↷
= 8 [plug this back into the top equation to get 40 units]
[8][40] = 320 [Area]

The formula for percentage increase is the increase in the original value. Between last year and this year, there was an increase of 9 science projects, so the increase = 9. The original number of science projects = 43.
9 divided by 43 = 0.2093, about. Multiply it by 100 to get it as a percentage: 20.93%
Since the problem requests it rounded to the nearest tenth, the percent change in the number of projects submitted is 20.9%.
Answer:
it should be <...........
The height of the chimney above the floor of the observation deck is 52.4 ft
Two right angle triangle will be formed.
<h3>Right angle triangle:</h3>
Right angle triangle are triangle that has one of its angle as 90 degrees.
Therefore, using trigonometric ratio,
adjacent side = distance of observer from the bottom edge of the Delaware River drawbridge observation deck
Therefore,
tan 40 = opposite / adjacent
Where
x = height of the observer to the top of the observation deck
tan 40 = x / 200
x = 200 tan 40
x = 167.819926235
x = 167.82 ft
tan 30 = opposite / adjacent
y = height of the observer to the bottom of the observation deck
tan 30 = y / 200
y = 200 tan 30
y = 115.470053838
y = 115.47 ft
The height of the chimney above the floor of the observation deck = height of the observer to the top of the observation deck - height of the observer to the bottom of the observation deck
The height of the chimney above the floor of the observation deck = 167.82 - 115.47 = 52.35 ft
