add 8 1/2 + 2 1/2=11
add 11 + 2 1/2=13 1/2
the area would be 11 x 13 1/2
Answer:
162
Step-by-step explanation:
a=
a=base and the base is 13 ft.
b= also means base which is 23 ft.
h= height which is 9 ft.
so 13+23 is 36
36/2 is 18
and 18 times 9 is 162
sorry for the lengthy answer but i hope this helps :) have a nice day !!
Answer:
125.25 ft
Step-by-step explanation:
The geometry of the problem can be modeled by a right trianlge in which the side adjacent to the angle is 310 ft, and the side opposite the angle is the one we want to find. The relevant trig relation is ...
Tan = Opposite/Adjacent
__
Solving for the Opposite side (the height of the balloon), we find ...
Opposite = Adjacent · Tan
height = (310 ft)·tan(22°) ≈ 125.25 ft
Enola's balloon is about 125.25 ft above the ground.
_____
<em>Additional comment</em>
If we assume Enola's angle measurement can have a possible error of ±0.5°, then the corresponding error in the balloon height is more than ±3 ft. It is a bit of nonsense to report the height to the nearest 0.12 inches, (0.01 ft).
Answer:
Step-by-step explanation:
Lines and are parallel because
The distance between two lines and can be calculated using formula
Divide the equation of the second line by 2:
Hence, the distance between two lines is
Answer:
Step-by-step explanation:
7/15=63/x
7x/15=63
7x=15(63)
7x=945
x=135
So the missing term is 135.
