The cost of a t-shirt was $30. Now the t-shirt costs $37.50. What is the percent of change? Do the work on your own paper and write your answer as a number.

Answers

Answer:

25%

Step-by-step explanation:

Given that,

Initial cost of a t-shirt = $30

Final cost of a t-shirt = $37.50

We need to find percent of change. The percentage change in any value is given by :

[tex]\%=\dfrac{\text{final value-initial value}}{\text{initial value}}\times 100\\\\=\dfrac{37.5-30}{30}\times 100\\\\=25\%[/tex]

Hence, the percentage error is 25%.

3x = 33

x = 11

CD = 9x - 25 = 99 - 25 = 74

DE = 6x+8 = 66 + 8 = 74

CE = 10x - 73 = 110 - 73 = 37

17 apples and 12 oranges cost $10.44. 3 apples and 4 oranges cost $2.84. How much does 1 orange cost?

Answers

Answer:

0.48$

Step-by-step explanation:

Cost of 1 Apple = A

 

Cost of 1 Orange = O

 

 

Six apples and three oranges cost $3.36 equivalent to:

 

6A + 3O = 3.36 (1st equation).

 

Two apples and five oranges cost $3.04 equivalent to:

 

2A + 5O = 3.04 (2nd equation).

 

 

Now we have to solve the 2 equations with 2 uknowns (the cost of 1 Apple = A, and the cost of 1 Orange = O).

 

6A + 3O = 3.36 (Equation 1)

2A + 5O = 3.04 (Equation 2), multiplying this equation by 3 we get:

 

6A + 3O = 3.36 (Equation 1)

6A + 15O = 9.12 (Equation 2), Now equation 2 minus equation 1 we get:

 

 

6A-6A +15O -3O = 9.12-3.36 equivalent to:

 

12O = 5.76 => O = 5.76/12 = 0.48 ( the cost of one Orange is 0.48$)

 

Go back to equation 1 and solve for the cost of 1 apple:

 

6A + 3x0.48 = 3.36 =>

6A + 1.44 = 3.36 =>

6A = 1.92 =>

A = 1.92/6 = 0.32 ( the cost of one apple is 0.32$)

 

Summary: The cost of one apple is 0.32$ and the cost of one orange is 0.48$.

Maya is going to watch a movie in her collection. She has 3 action movies, 11 comedies, and 9 dramas. She will randomly select one movie. What is the probability that the movie she selects is not a comedy?

Answers

Answer:

The probability is 12/23

Step-by-step explanation:

We calculate the number of movies in her selection

Mathematically, that will be;

3 + 11 + 9 = 23

The number of movies that are not comedy will be;

3 + 9 = 12

So the probability of selecting a movie that is not comedy will be 12/23

HELP PLEASE! Write a quadratic function that passes through the point (-1,9), has an axis of symmetry of x=-3 and a minimum value of 7.

Answers

Answer:

[tex]y = \frac{1}{2}x^{2} - 3x + 11.5[/tex]

Step-by-step explanation:

Vertex Form of a quadratic equation;

[tex]y = a( x - h )^{2} + k[/tex]

Vertex of the parabolas (h, k)

The vertex of the parabola is either the minimum or maximum of the parabola. The axis of symmetry goes through the x-coordinate of the vertex, hence h = -3. The minimum of the parabola is the y-coordinate of the vertex, so k= 7. Now substitute it into the formula;

[tex]y = a ( x + 3 ) ^{2} + 7[/tex]

Now substitute in the given point; ( -1, 9) and solve for a;

[tex]9 = a( (-1 ) + 3)^2 + 7\\9 = a (2)^{2} + 7\\9 = 4a + 7\\-7 -7\\2 = 4a\\\frac{1}{2} = a\\[/tex]

Hence the equation in vertex form is;

[tex]y = \frac{1}{2}(x - 3)^{2} + 7[/tex]

In standard form it is;

[tex]y = \frac{1}{2}x^{2} - 3x + 11.5[/tex]
