Answer:

x = 11, CD = 74, DE = 74, and CE = 37

Step-by-step explanation:

9x-25 = 6x+8

3x - 25 = 8

3x = 33

x = 11

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

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

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

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%.

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]

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

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$.

The answer is 48¢... Hope it helps!!

How much does the depth of the lake increase in four years? Read the passages:Passage A Minerals, water, air, organic matter, and organisms make up the material we call soil. This material covers the Earth's surface and supports life. Without soil, plants would not grow, and animals would not survive.Even though speaking about soil seems simple enough, it is actually very complex. That is because soil comes in many different forms which are made of layers, called horizons. When you look at the horizons together, you get a soil profile. Each horizon has its own set of characteristics. Some soil characteristics are the amount of sand, the type of minerals, and the amount of decomposing leaves found in the soil. All of these characteristics will help determine what kind of plant life the soil can support.Passage B Healthy plants are plants that are able to take sunlight, water, and nutrients and turn them into food. Their roots absorb two of these ingredients from the soil around them. The ideal soil for growing is one that contains the right amount of water without being too wet. It also contains many nutrients.How do nutrients make it into the soil? The answer is actually quite complex. Nutrient-rich soil contains organic matter, which is broken-down plant and animal matter. As the plant and animal matter decays, or decomposes, it releases nutrients into the soil. Then, it is absorbed by living plants and turned into food. Therefore, the richer the nutrients in the soil, the healthier the plant.Based on the information in Passages A and B, how do the nutrients in the soil determine what kind of plant it can support? In order to get nutrients into the soil, plants and animals decompose, which means they are broken down and absorbed as food. Plants absorb the nutrients they need from the soil to make food, so the type of nutrients in the soil need to match the type of nutrients needed by the plant. Soil horizons share their nutrients so that plants and animals have enough food to survive, especially during the summer season. The minerals, water, and organic matter in the soil keep plants from growing large, so plants need to choose a spot that doesn't have any of those things. Plants appear green because they do not absorb the green wavelengths of light. What happens to those green light waves when they hit a plant? The are diffracted. They are absorbed. They are reflected. They are refracted.
