Answer:
The slope would be 0
Step-by-step explanation:
Answer: 1.78 L are needed to complete the gallon and it will take 29.66 min to completely fill it
Step-by-step explanation:
The question in english is:
A gallon of water needs to be filled, in 2 liters it takes 30 minutes. How many liters do I need to complete the gallon and what is the time it takes me to fill it?
We know 1 gallon is equal to 3.78 liters:
In addition, we are told you have filled the gallon with 
at a rate of 
.
So, if we want to know how many liters are left to completely fill the gallon, we have to sbstract the to the total amount of a gallon:
This is the amount you need to complete the gallon
On the other hand, the rate is defined as:
Isolating 
:
Then, if we input the 
we need to fill the gallon we will have the time:
This is the time you need to fill the gallon
We have consecutive odd numbers for the sides of a triangle, perimeter 201. We could write an equation, but clearly the middle side is 201/3 = 67, so the other two sides are 65 and 69.
This is almost an equilateral triangle, angles around 60 degrees, so not obtuse, meaning one angle over 90 degrees.
Scalene means the sides are all different lengths; we didn't even have to solve the problem to know this is true.
Smallest side 61, false.
Largest side 69, true.
This last one doesn't make much sense to me. What's a unit here? Dilation of 1/3 means all the linear measures become 1/3 as big, including the perimeter. It would decrease much more than 3 inches, since it would go from 201 inches to 67 inches. If I have to answer I'd go with false.
