Remark
Make up a proportion that relates the tree and its properties to the stick and its properties.
Givens
Stick height (s_h) = 4
Stick shadow(s_s) = 2
Tree shadow = t_s = 18
Tree height = x
Formula
s_h / s_s = x / t_s
Substitute and solve.
4/2 = x / 18 Cross multiply
4*18 = 2 * x
72 = 2x Divide by 2
72/2 = x
x = 36
The height of the tree is 36 feet.
Y = mx + b
M= your slope or rise over run
B = your y-intercept
For example if the rise was 5 and the run is 6, the equation would say
y = 5/6 + b
The / being your fraction bar
The y-intercept is where your line crosses the y-axis
So say that the line crosses the y-axis at 10
y = 5/6 + 10
That about sums it all up!
25.83 x 6 = 154.98
If the purchased television is 245.95 and you make 6 payments that total in
154.98 dollars, the down payment will be what is left.
40.25% = 0.4025
245.95 x 0.4025 = 98.99
98.99 dollars off the original price.
245.95 - 98.99 = 146.96
The down payment made the total come to 146.96.
146.96 + 154.98 = 301.94
The total amount paid is 301.94 including charge and down payment.
answer x = 225 and y = -135
Step-by-step explanation:
x+y = 90 and x= 90-y and x -y = 360 so 90-y -y = 360
