5-3/2x>1/3what is x?

Answers

Answer 1

Coco, this is the solution to the inequality:

5 - 3x/2 ≥ 1/3

Subtracting 5 at both sides:

5 - 3x/2 - 5 ≥ 1/3 - 5

-3x/2 ≥ 1/3 - 15/3

-3x/2 ≥ -14/3

LCD (Least Common Denominator) between 2 and 3 : 6

-9x/6 ≥ -28/6

Dividing by -9/6 at both sides:

-9x/6 / -9/6 ≥ -28/6 / -9/6

x ≥ 28/9

In consequence, the correct answer is C. x ≥ 28/9

Based on the experimental probability, predict the number of times that you will roll a 5 if you roll the number cube 300 timesExperiment result on previews question: The number 5 was rolled 9 times out of 20 on a previous question

Answers

Explanation: To understand this problem we need to know that there are two different types of probability. The experimental probability and the theoretical probability.

- The experimental probability occurs once you conduct the experiment and after the experiment, you calculate the probability using the result of the experiment.

- The theoretical probability occurs before the experiment. Once you have information about the situation so you calculate the probability the get a specific result before trying.

Step 1: For this question, once we have a number cube with faces 1,2,3,4,5 and 6 and we want to know the experimental probability to get a 5 once you roll the cube 300 times you would need to get in real life a number cube and to roll it 300 times. After this experiment we would get all the results of each time we roll it and we would know how many times (from 300 times) we got a number 5. After that, we would use the following formula

[tex]Experimental_{probability}=\frac{number\text{ of times we got a number 5}}{300}[/tex]

Once the get this result we finish the question.

Find the expression for the possible width of the rectangle.

Answers

Given the area of the rectangle is given by the following expression:

[tex]A=x^2+5x+6[/tex]

The area of the rectangle is the product of the length by the width

So, we will factor the given expression

To factor the expression, we need two numbers the product of them = 6

and the sum of them = 5

So, we will factor the number 6 to find the suitable numbers

6 = 1 x 6 ⇒ 1 + 6 = 7

6 = 2 x 3 ⇒ 2 + 3 = 5

So, the numbers are 2 and 3

The factorization will be as follows:

[tex]A=(x+3)(x+2)[/tex]

So, the answer will be the possible dimensions are:

[tex]\begin{gathered} \text{Length}=x+3 \\ \text{Width}=x+2 \end{gathered}[/tex]

Explain when you can cancel a number that is in both the numerator and denominator and when you cannot cancel out numbers that appear in both the numerator and the denominator.

Answers

Let me write here an example of a common number/term in both numerator and denominator that we can cancel.

[tex]\frac{4xy}{4}=xy[/tex]

In the above example, we are able to cancel out the common number 4 because they are stand alone numbers. We can divide 4 by 4 and that is 1. Hence, the answer is just xy.

Another example:

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

In the above example, we are able to cancel out (x + 2) because this term is a common factor to both numerator and denominator.

In the example, we can also see that -1 is a common number however, we cannot cancel it out because the number -1 is not a standalone factor. It is paired with other number/variable. (x - 1) and (2x - 1) are both factors but are not the same, that is why, we are not able to cancel that.

Another example:

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

As we can see above, (x + 2) is a common term however, we cannot cancel it. We can only cancel common terms if they are common factors of both numerator and denominator. (Notice the plus sign in the middle. )

The term (x + 2) above is not a factor of the numerator and denominator, hence, we cannot cancel it.

Answers

Answer:

P = 0.04

Explanation:

The probability is equal to the number of options where the first spinner is landing on the color pink and the second spinner is landing on the number 5 divided by the total number of options.

Since there is only one option that satisfies the condition P5 and there are 25 possible outcomes, the probability is:

Use technology to write an equation for the line of best fit from the data in the table below. Round all values to two decimal places.

Answers

1) Let's visualize the points

2) To find the equation for the line of best fit we'll need to follow some steps.

2.1 Let's find the mean of the x values and the mean of the Y values

2.2 Now It's time to find the slope, with the summation of the difference between each value and the mean of x times each value minus the mean over the square of the difference of the mean of x and x.

To make it simpler, let's use this table:

The slope then is the summation of the 5th column over the 6th column, we're using the least square method

Answers

The given line is

[tex]\begin{gathered} m\cdot m_1=-1 \\ m\cdot(-2)=-1 \\ m=\frac{-1}{-2} \\ m=\frac{1}{2} \end{gathered}[/tex]

Now, we use the slope, the point, and the point-slope formula to find the equation.

Use the graph below to determine the equation of the circle in (a) center-radius form and (b) general form.10-(-3,6)(-6,3(0,3)-10(-3,0)1010

Answers

Question:

Solution:

An equation of the circle with center (h,k) and radius r is:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

This is called the center-radius form of the circle equation.

Now, in this case, notice that the center of the circle is (h,k) = (-3,3) and its radius is r = 3 so that the center-radius form of the circle would be:

[tex](x+3)^2+(y-3)^2=3^2[/tex]

To obtain the general form, we must solve the squares of the previous equation:

[tex](x+3)^2+(y-3)^2-3^2\text{ = 0}[/tex]

this is equivalent to:

[tex](x^2+6x+3^2)+(y^2-6y+3^2)\text{ - 9 = 0}[/tex]

this is equivalent to

[tex]x^2+6x+9+y^2-6y\text{ = 0}[/tex]

this is equivalent to:

[tex]x^2+y^2+6x-6y\text{ +9= 0}[/tex]

so that, the general form equation of the circle would be:

[tex]x^2+y^2+6x-6y\text{ +9= 0}[/tex]

thus, the correct answer is:

Jackson purchased a pack of game cards that was on sale for 22% off. The sales tax in his county is 6%. Let y represent the oeiginal price of the card.. Wrote an expression that can be used to determine the final cost of the cards.

Answers

Given:

Discount - 22% = 0.22

Sales Tax - 6% = 0.06

Required:

Expression for the final cost of the cards, x

Solution:

Let: y represent the original price of the card.

x represent the final cost of the cards

D represent the discounted cost of the cards

Assume that the the sales tax is applied to the price after the discount.

D= Original Price ( 1 - Discount) = y ( 1 - 0.22) = 0.78y

To compute for the final cost,

Final Cost = D + Tax

Tax = 0.06 D

x = D + 0.6(D)

x = 1.06D

x = 1.06 ( 0.78 y)

x = 0.827y

Answer:

The final cost of the card can be describe by the expression:

x = 0.827y

Composite functions is a function that depends on another function.  A composite function is created when one function is substituted into another function.

In other words, a composite function is generally a function that is written inside another function.

Therefore,

f(x) = 2x

g(x) = 3x²

Hence, the composite function can be simplified as follows:

(f + g)(x) = f(x) + g(x)  = 2x + 3x²

(f - g)(x) = f(x) - g(x)  = 2x - 3x²

(f. g)(x) = f(x) . g(x) = (2x)(3x²) = 6x³

(f / g)(x) = f(x) / g(x) = 2x / 3x² = 2 / 3x

- If each triangle subtends an angle α at the center of the hexagon, it means that we can find the value of α since all the α angles are subtended at the center of the hexagon using the sum of angles at a point which is 360 degrees.

- That is,

[tex]\begin{gathered} α=\frac{360}{6} \\ \\ α=60\degree \end{gathered}[/tex]

- We also know that regular hexagon is made up of 6 equilateral triangles.

- Thus, the formula for finding the area of an equilateral triangle is:

[tex]\begin{gathered} A=\frac{\sqrt{3}}{4}x^2 \\ where, \\ x=\text{ the length of 1 side.} \end{gathered}[/tex]

- Thus, the area of the hexagon is:

[tex]A=6\times\frac{\sqrt{3}}{4}x^2[/tex]

- With the above formula we can find the length of the regular hexagon as follows:

[tex]\begin{gathered} 40.6=6\times\frac{\sqrt{3}}{4}x^2 \\ \\ \therefore x=15.626947286066 \end{gathered}[/tex]

- The formula for the volume of a hexagonal pyramid is:

[tex]\begin{gathered} V=\frac{\sqrt{3}}{2}b^2\times h \\ where, \\ b=\text{ the base} \\ h=\text{ the height.} \end{gathered}[/tex]

- Thus, the volume of the pyramid is

[tex]\begin{gathered} V=\frac{\sqrt{3}}{2}\times15.626947286066^2\times3.7 \\ \\ V=782.49cm^3 \end{gathered}[/tex]

SOLUTION:

Case: Circle theorems

Method:

From the given circle

Theorem: The angle at the center of the circle is twice the angle at the circumference formed by the same segment.

The implication to the circle in the question is:

[tex]\begin{gathered} \hat{mST}=2m\angle2 \\ OR \\ m\angle2=\frac{1}{2}(\hat{mST}) \end{gathered}[/tex]

Final answer

[tex]m\operatorname{\angle}2=\frac{1}{2}(\hat{mST})[/tex]
