Answer:
The rate of change for the number of parakeets seen is 1/2
Step-by-step explanation:
The sightings can be approximated by the equation:
y = (1/2)*x + 3
Which represents a line. Any line can be writen by an equation in the following form:
y = m*x + b
Where m is the slope of the lane or it's rate of change and b is the value for "y" when "x" equals zero. Applying this knowledge to the equation of the bird sightings we can se that the sightings grows 1/2 for every one unit that x grows, therefore the rate of change is 1/2.
2 burgers for $7.79
1 bowl of soup for $4.99
4 drinks for $1.39
They paid 6% tax. They then paid a tip that was about twice the amount of the tax they paid. Which is the closest estimate of the total amount Ethan and his friends paid for their food, drink, tax and tip?
A) $50
B) $35
C) $35
D) $60
6.29 * 2 = 12.58
7.79 * 2 = 15.58
4.99
1.39 * 4 = 5.56
12.58 + 15.58 + 4.99 + 5.56 = 38.71 <-- total without tax/tip
38.71 * .06 = 2.32 <-- tax
2.32 * 2 = 4.64 <-- tip
38.71 + 2.32 + 4.64 = 45.67 <-- total cost
The closet to the total cost would be option A) $50

Answer:
No, the ratios 20:8 and 7:3 do not form a proportion.
Step-by-step explanation:
If it is 20:8 to 7:2.8 then it would form a proportion.
Hope this helps.
