Hi
The answer in this question is 14.5.
Just add those numbers together and divide it by the amount of students
Answer:
The original price of the sweater was $28
Step-by-step explanation:
To find out the answer to this problem you need to first convert the percent into a decimal which would be 0.4 and then to solve the problem in one step you need it to be 140% which would be 1.4 as a decimal. Then you need to multiply 20 by 1.4 which gives you 28 and 28 would be the total cost of the shirt at it's regular price.
(x,y)=(2,1) where the two lines intercept
so for the first equation you go on the y line and dot -4 then count up 5 times then right 2 times since it’s rise over run
for the second line start at positive 3 on the y line then it’s -1/1 which is up once and left once cause of the negative

Answer: 3/5</h3>
Explanation:
For angle A, the side furthest from here is BC = 15. This is the opposite side for this reference angle.
The hypotenuse is AC = 25, which is the longest side of any right triangle (always opposite the 90 degree angle).
The sine ratio involves dividing the opposite over hypotenuse.
So,
sin(angle) = opposite/hypotenuse
sin(A) = BC/AC
sin(A) = 15/25
sin(A) = (3*5)/(5*5)
sin(A) = 3/5
we know that
The equation of a vertical parabola in vertex form is equal to

where
(h,k) is the vertex
if
-----> then the parabola open upward (the vertex is a minimum)
if
-----> then the parabola open downward (the vertex is a maximum)
The axis of symmetry is equal to

In this problem let's analyze two cases
First case

the vertex is the point 

so
-----> then the parabola open upward (the vertex is a minimum)
The axis of symmetry is equal to

Second case

the vertex is the point 

so
-----> then the parabola open upward (the vertex is a minimum)
The axis of symmetry is equal to
