I bought four bags of cotton candy for $1.50 each and two soft drinks for 90 cents each. What was my change from a ten dollar bill
Answer:
Your change is $2.20
Step-by-step explanation:
4 x $1.50 = $6
2 x $.90 = $1.80
$6 + $1.80 = $7.80
$10 - $7.80 = $2.20
So it's $2.20. Have a nice day :D
Answer:
$2.20
Step-by-step explanation:
4 bags of cotton candy
$1.50 x 4 = $6.00
2 soft drinks
$0.90 x 2 = $1.80
$6.00 + $1.80 = $7.80
$10.00 - $7.80 = $2.20

A rectangle has an area of 2x2 - 19x +45 ft? What are the dimensions of the rectangle? (hint: factor)
The dimensions of the rectangle will be (2x - 9)(x - 5).
What is a quadratic equation?A quadratic equation is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.
Given that the area of the rectangle is represented by a quadratic equation 2x² - 19x +45.
The dimensions of the rectangle will be the factors of the quadratic equation.
2x² - 19x + 45
2x² - 10x -9x + 45= 0
2x( x - 5 )-9(x - 5)= 0
( 2x - 9 ) ( x - 5 ) = 0
Therefore, the dimensions of the rectangle will be (2x - 9)(x - 5).

Answer:
(0, -10), (2, 0), (-2, -50)
Step-by-step explanation:
Plug in numbers for the x and solve for it
I will start with 0
y = 5(0 - 1)^2 - 5
y = 5(-1) - 5
y = -5 - 5
y = -10
2
y = 5(2 - 1)^2 - 5
y = 5(1) - 5
y = 5 - 5
y = 0
-2
y = 5(-2 - 1)^2 - 5
y = 5(-9) -5
y = -45 - 5
y = -50
You just keep plugging in numbers until your graph finds its shape. Of course, you can chart the numbers I have already found.

Someone pls help. Write the equation in standard form
Answer:
Step-by-step explanation:
Since, zeros of the relation are 5, 6 and y-intercept is (0, 30).
Therefore, equation of the quadratic relation will be in the form of,
y = a(x - 5)(x - 6)
For (0, 30),
30 = a(0 - 5)(0 - 6)
30 = 30a
a = 1
Therefore, equation will be,
y = (x - 5)(x - 6)
y = x² - 11x + 30
y = x²- 2(5.5)x + (5.5)² - (5.5)² + 30
y = (x - 5.5)²+ 30 - 30.25
y = (x - 5.5)² - 0.25 [Standard form}
b). Vertex → (-4, -7) and passes through a point (-2, 1)
Vertex form or standard equation of the quadratic relation is,
y = a(x - h)² + k
Here, (h, k) is the vertex
Therefore, equation will be,
y = a(x + 4)² - 7
Since, (-2, 1) lies on this relation
1 = a(-2 + 4)² - 7
a(2)²- 7 = 1
4a = 8
a = 2
Equation will be,
y = 2(x + 4)²- 7
Part B Isabella's mother sells the peas and gets $3 for each square foot. So, multiply your answer from Part A by 3 to calculate how much money Isabella's mother made.
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete as the solution to part A (or part A itself) is not given. To solve this, I will assume a value to the supposes solution to part A.
From the question:
1 square foot is sold at $3.
This implies that:
p square foot will be sold at $3p.
So, total sales can be calculated using:
[tex]Total = 3p[/tex]
Now assume that p is 10 square feet (from part A).
The total will be:
[tex]Total = 3*10[/tex]
[tex]Total = \$30[/tex]
