The points are (-3,3) and (2,2) then you use distance formula to find the distance between them
The conclusion that is valid based on the result of the test would be : A. Her students on average, do not take 30 minutes on the quiz, contrary to what the textbook company stated
we can see in the statement that the average student only need about 25 minutes to take the quiz
hope this helps
Answer: 
Step-by-step explanation:
We can use the following formula to solve this exercise:
In this case "T" is the time in hours it takes to both taps fill the pool working together, "A" is the time in hours for the first tap filling the pool alone an "B" is the time in hours for the second tap filling the pool alone.
We can identify that:
Then, we must subsitute the known values into the formula:
And finally we must solve for "B".
Then we get:
Answer:
157.075, yes, it was reasonable
Step-by-step explanation:
15.25×10.3=157.075
First you have 2 triangles and 3 rectangles so you will get the area of 5 of them
for the first face of rectangle
2.5x10=25
second face
2x10=20
for the third rectangle which is the base
10x1.5=15
for the two triangles
1/2xBasexHeight
1/2x1.5x2=1.5 ——> this is for one triangle so multiply by 2 to get both triangles
1.5x2=3
so the total surface area is equal to 3+25+20+15=63
