You have the area of the squares
100 in^2
area of a square = l*w
so length and width of the square both equal 10in
there are 4 squares going across the semi circle so...
diameter of semicircle is 10+10+10+10 =40in and radius is 20in
to find area of semicircle the formula is 1/2 pi r^2
so plug in the numbers 1/2(3.14) (20)^2 = 628 in ^2
now add that to area of big square part of window
40 inches length * 40 inches width = 1600in^2 (or you can just add them all up )
add up the areas now 1600+628= 2228 in^2
i think that is right
Answer:
y= -7 and x= -1
Step-by-step explanation:
To do this, line up the variables so it looks like this...
y-6x=-1
y-3x=-4
The reason why -6x and -3y changes to negative is because that it moved to the other side of the equation.
distribute negative to the bottom equation because the two equations have the same number variable which is y...
y-6x=-1
-y+3x=4
Y cancels out and it will be left with -3x = 3.
X = -1.... plug that in to any of the two equation and you get y = -7.
Hope I helped and have a nice day!!
Answer:
1011.05
Step-by-step explanation:
Let's use 3 as an example.
The angle of depression is the one directly under the ballon.
You also know that the 53 degree angle is part of a 90 degree angle.
so the angle inside the triangle directly under the balloon is 37 degrees.
You know the angle and you know the side from the balloon to the ground is 1680. This is the hypotenuse of the triangle.
So which trig function could you use to determine how high the balloon is from the ground?
SOH CAH TOA
cos 37 = a/1680
a = 1341.71
