Answer:
Therefore the area of the screen cleared is 1414.28 cm².
Step-by-step explanation:
Given:
a windscreen wiper of a vehicle of length 30 cm
Consider this length as Radius of Semicircle, r = 30 cm
clears out an angle of 180 degrees implies Semicircle Shape
pie=22/7
To Find:
Area of the screen cleared
= ?
Solution:
We have

Substituting r and pie we get

Therefore the area of the screen cleared is 1414.28 cm².
102 multiply 5 is equally to 610 so that's gonna be 6.10 I think
Answer:
Parallel lines
Step-by-step explanation:
Line BC:

Line AD:

Adding both equations, in this case, gives us the point at which the lines intersect:

Since zero will never equal fourteen, the equation above means that lines BC and AD will never intersect. When two lines have no point in common, they are said to be parallel lines.
Answer:
x=-2
Step-by-step explanation:
Hey there!
In order to solve this equation, you need to combine like terms
The equation after combining the x terms and the contants will look like this
10x+3=12x+7
Now you have to take 10x away from both sides
3=2x+7
Now bring all the constants to the left side
3-7=2x
Simplify
-4=2x
divide 2 on both sides to get x by itself
x=-2
So, the answer is x=-2
