For this case we have that by definition, the equation in the form of slope-intersection is given by:

Where
Substituting the given point:
and the cutoff point
we can find the slope,
We have:


Thus, the equation is given by:

Answer:

See attached image
1/4 / 1/2 =
1/4 x 2/1 = 2/4 = 1/2
$1.80 if the question was ( he would have 3/5 of the amount he started with)
Answer:
21 feet
Step-by-step explanation:
To solve this question, we would be using the proportion
Shadow /Height
From the question:.
Manny's shadow = 414 feet
Manny's Height = 512 feet
Height of the tree = ? = x
Shadow of the tree = 17 feet
Hence:
414/512 = 17/ x
Cross Multiply
414 × x = 512 × 17
x = 512 × 17/414
x = 21.024154589 feet
x ≈ Approximately = 21 feet
The height of the tree = 21 feet
