Answer:
<em>Donna will have to pay $67.985125 at the register, including the 7% sales tax.</em>
Step-by-step explanation:
Donna bought 3 pairs of pants for $28.50 each.
So, the cost for 3 pair of pants dollars.
She also bought a necklace for $12.25
Thus, the cost for her entire purchase will be: dollars.
She received a discount of 35% off her entire purchase. So, the amount of discount dollars.
Thus, the total selling price will be: dollars.
Percentage of sales tax is 7%. So, the amount of sales tax dollars.
Thus, the total amount Donna have to pay at the register dollars.
Answer:
1. 82.75
2.10.65
3. 93.4, 72.1
4. 104.05, 61.45
5. 114.7, 50.8
6. Yes
7. Because of the placement of these ranges on the graph
8. 35/91 = .38 %
By taking the amount of all of the students who scored a 90 or above and dividing it by the total amount of students.

Answer:
5/31
Step-by-step explanation:
To find a factor you need to see the numbers you get after multiplying for instance:
What r the factors of 7?
7x1 is 7
7x2 is 14
7x3 is 21
7x4 is 28
7x5 is 35
So on and so fourth, whatever your result is in the problem, will be one factor. So this is what you would do to find the factors of 17!
Answer:
y = x² - 8x + 18
Step-by-step explanation:
The minimum value occurs at the vertex, thus the y- coordinate of the vertex is 2
The axis of symmetry is vertical and passes through the vertex , thus the x- coordinate of the vertex is 4
The vertex of the quadratic is therefore (4, 2 )
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier.
let a = 1, then
y = (x - 4)² + 2 ← expand (x - 4)² using FOIL
= x² - 8x + 16 + 2
y = x² - 8x + 18 ← is a possible equation
