Answer:
Each piece of ribbon lengths 2.55 feet.
Step-by-step explanation:
A 30-foot piece of ribbon that Elena has cut for a craft project. Then she cuts off 7 feet from this.
So, the remaining length of the ribbon for the craft project will be (30 - 7) = 23 feet.
Now, then she cuts the remaining piece into 9 equal lengths of feet each.
Hence, each piece of ribbon lengths 
feet. (Answer)
<span>"Rate of change" is how much one variable changes when the other changes. In linear equations this is know as "slope" (since slope equals the change in Y relative to the change in X). Next remember that any linear equation can be written in the form: y = mx + b, where m = slope and b = y-intercept (place where line crosses the y-axis). Therefore to figure out rate of change (or slope) of a linear equation simply rewrite the equation in the y = mx + b form. In your case, the equation is already written that way. y = 1.5x (note that in this case b = 0) So in this formula m = 1.5. The rate of change is equal to 1.5. Another way this could be said is that when x increases by one unit, y will increase by 1.5 units. Plugging in any set of numbers will show this is true: If X = 1; Y = 1.5 If X = 2; Y = 3 (X increases by 1; Y increases by 1.5) If X = 3; Y = 4.5 (Again X increase by 1; Y increase by 1.5) ...</span>
Opportunity cost when 3 military outfits are produced is 30
Opportunity cost when 4 military outfits are produced is - 35.
Opportunity cost when 5 military outfits are produced is -50.
As military outfit increases, opportunity cost declines.
<h3>What is the opportunity cost?</h3>
Opportunity cost of the next best option forgone when one alternative is chosen over other alternatives
<h3>What is the opportunity cost of producing military outfits? </h3>
Opportunity cost = change in the total pounds of butter produced / change in total outfit produced
Opportunity cost when 3 military outfits are produced = (85 - 115) / (3 - 2) = 30
Opportunity cost when 4 military outfits are produced = (50 - 85) / (4 - 3) = - 35
Opportunity cost when 5 military outfits are produced = (0 - 50) / (5 - 4) = -50

Find volume of right circular cylinder
V = pie * r * r * h
= 3.14 * 1.35/2 * 1.35/2 * 5 ft^3
= 7.153 ft^3
Since 1ft^3 = 7.5 gallons
7.153 ft^3 = 7.5 * 7.153 gallons
i.e equal to 53.65 gallons
Answer:
71º
I would give an explanation, but it sound like you could use this answer sooner than later.
