Answer: 170.37 acres
Step-by-step explanation:
In 2005, x= 2005
Substituting x=2005 in the equation.
A(2005) = (2078x-94458)/(13x-2164)
A(2005) = 4071932/23901
A(2005) = 170.37 acres
Answer:
36.7 ft
Step-by-step explanation:
Measurements for the sides of the canal is given as: 40 ft. and 16 ft.
You solve the above question using Pythagoras Theorem
The distance across the canal is calculated as:
√(40² - 16²)
= √(1344)
= 36.66060556 ft
Approximately = 36.7 ft
Therefore, the distance x across the canal = 36.7 ft
Answer:
y = -1 x = 4
Step-by-step explanation:
(X+3y=1) 5 Multiply this equation by 5 to cancel out the x
-5x+4y=-24
-5x + 4y= -24
+ 5x + 15y = 5 Add both equations together
19y = -19 Divide both sides by 19
y = -1
Plug -1 for y into one of the equations
x + 3(-1) = 1 Multiply 3(-1)
x - 3 = 1
+ 3 + 3 Add 3 to both sides
x = 4

=74 m
Step-by-step explanation:
given that three locations are marked next to a river. Points B and C are on the same side of the river, and point A is on the other side of the river. To find the distance AB across a river, a distance BC of 241 meters is laid off on one side of the river. It is found that the angle at point B is 108.6° and the angle at point C is 14.9°.
we have information about triangle ABC as side BC =241, Angle B = 108.6 and angle C = 14.9 degrees.
Hence this is an obtuse scalene triangle.
Angle ∠A = 56.5° (III angle)
Using sine formula we get
So distance AB is 74 metres.
