Answer:
a. 4/5
b. 150 and 120
Step-by-step explanation:
To find the scale factor first find two sides that correspond and have measurements. This is the length of each rectangles which are 50 and 40.
The equation for scale factor when scaling down is
SF = Smaller Length / Longer Length
When scaling up it is
SF = Longer / Smaller
We are scaling down so we plug in our numbers.
SF = 40 / 50
Solve for SF = .8 or 4/5.
For permimiter you add all four sides. Multiply the width of the larger pool by the scale factor. 25*.8 = 20
20 + 20 + 40 + 40 = 120
25 + 25 + 50 + 50 = 150
a. equate yourequation to zero then yourx intercepts are (-6;0) and (4;0)
b. to find the y-intercept...let x=0...where there is x put 0 and your answer is -24 therefore the y-intercept is (0;-24)
A:Kim paid the most
Since 3/7 is 42.8%
Answer: y= 3/2x+8
