y^2 / 6x^2 + 2x + z
I'm not that certain that this is it, but my best guess.
In this problem, the reference of the scale is referring to feet. Firstly, convert 72 inches to feet so that you can properly make the proportion.
72 inches = 6 feet
With the scale of 2 inches per 3 feet, we can set up an easy proportion to see how wide the door will be on the drawing.
3 feet 6 feet
——— = ————
2 inc. ‘x’ inc.
3x=12
X=4 inches
Solving the proportion by cross-multiplication reveals that the scale drawing of the patio door would be 4 inches wide.
It’s 20+40=60
24+37=60 rounding to the nearest 10 is 60
If they are 2.5 inches tall and the back splash is 2.5 feet tall that means you can fit 12 tiles vertically.
6 inches is 1/2 of a foot so 16 tiles can fit horizontally in 8 feet.
12 x 16 = 192
Final answer:
192 tiles
Hope I helped :)
we assign x as the upright side of the right triangle, 1 as the hypotenuse. in this case, the horizontal side or the base is square root of (1- x2). arc sin x is equal to theta. tan theta is equal to x / square root of (1- x2). The final answer is x / square root of (1- x2)
