Answer:
-0.45, 2/5, 54%
Step-by-step explanation:
54%=54/100
=87/50
2/5=20/50
-0.45 must be the smallest as it is negative
Answer:
Sketch the following three graphs:
1) y = (x - 5)²
2) y = -(x - 5)²
3) y = x - 5
First two are parabolas with vertex at (5,0)
Third one is a line which intersects both the parabolas as (5,0)
Let w = width
then
5w-3 = length
w(5w-3) = 14
5w^2-3w = 14
5w^2-3w-14=0
(5w+7)(w-2) = 0
w = {-7/5, 2}
throw out the negative solution leaving
w = 2 centimeters
length:
5w-3 =5(2)-3 =10-3 = 7 centimeters

<span> A toy jeep is 12 1/2 inches
Actual jeep is 18 ¾ feet long
before we determine the ratio, let’s convert first each size into the same unit
of measure and decimal points
=> 12 ½ = 25/2
=> 12.5 inches
=> 18 ¾ = 75/4
=> 18.75 feet
Now, let’s convert feet to inches to know the ratio
=> 1 foot = 12 inches
=> 12.5 inches : 225 inches
=> 225 / 12.5
=> 18 inches
thus in every 1 inch of toy car represents 1.5 feet of actual car.
