Answer:
75
Step-by-step explanation:
<h2>A=1/2h(a+b)</h2><h3> =10÷2=5(10+5)</h3>
=5×15
<h2> =75</h2>
So, each square on the grid is 10 inches in length and width
To find the dimension of the diagonal lengths, treat them like a hypotenuse so we can use the Pythagorean theorem.
a^2 + b^2 = c ^2
a and b are our length and width and c is the hypotenuse.
Make each diagonal length part of a triangle. There will then be 4 triangles to work with.
Triangle 1 (Top left)
Triangle 2 (Bottom left)
Triangle 3 (Top Right)
Triangle 4 (Bottom Right)
A right triangle made with the top left diagonal dimension will have a vertical dimension of 30 (10+10+10) and a horizontal dimension of 40 (10+10+10+10)
To find c or the hypotenuse, plug these into the Pythagorean theorem.
30^2 + 40^2 = c ^2
c^2 = 900 + 1600 = 2500
c = sqrt(2500) = 50
You will see that triangles 2, 3, and 4 have the same vertical and horizontal dimensions giving them the same value.
Now combine the dimensions
diagonal = 50+50+50+50 = 200
horizontal = 90+90 = 180
diagonal + horizontal = 380
Y = 3x - 4.....x int can be found by subbing in 0 for y and solving for x
0 = 3x - 4
-3x = -4
x = -4/-3
x = 4/3...so the x int = (4/3,0)
y - 2/3x = 0....in y = mx + b form, the m represents the slope. So ur slope is -2/3
