Answer:

The required solution is: [tex]x<\frac{23}{8}[/tex] or x<2.875 or [tex]\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:\frac{23}{8}\right)\end{bmatrix}[/tex]

Step-by-step explanation:

Consider the provided inequity.

[tex]24x>18(4x-6)-30[/tex]

We need to solve the above inequity of x.

Open the parentheses.

[tex]24x>18\times 4x-18\times 6-30[/tex]

[tex]24x>72x-108-30[/tex]

[tex]24x>72x-138[/tex]

Subtract 72x from both sides.

[tex]24x-72x>72x-138-72x\\-48x>-138[/tex]

Multiply both sides by -1 and reverse the inequality.

[tex]\left(-48x\right)\left(-1\right)<\left(-138\right)\left(-1\right)[/tex]

[tex]48x<138[/tex]

Divide both side by 48.

[tex]x<\frac{23}{8}[/tex]

Hence, the required solution is: [tex]x<\frac{23}{8}[/tex] or x<2.875 or [tex]\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:\frac{23}{8}\right)\end{bmatrix}[/tex]

The two expressions should be [tex]-4 \div 2 + 8 = 6\ and\ (10 \times -3) \div -5 = 6[/tex].

Given that,

Based on the above information, the calculation is as follows:

[tex]-4 \div 2 + 8 = 6\[/tex]

6 = 6

And,

[tex](10 \times -3) \div -5 = 6[/tex]

6 = 6

Therefore we can conclude that the two expressions should be [tex]-4 \div 2 + 8 = 6\ and\ (10 \times -3) \div -5 = 6[/tex].

Answer:

See below.

Step-by-step explanation:

I can't see any example but what I would do is first multiply both sides by 3.

4m/3 = 8

4m/3 * 3 = 8 * 3

4m = 24.

The first operation in solving the equation 4m/3 = 8 is multiplying both sides of the equation by 3, which eliminates the fraction and isolates the variable 'm'. After further simplification, the solution to the equation is m = 6.

To solve the equation 4m/3 = 8, the first operation we need to perform is to isolate the variable on one side of the equation. We can do this by multiplying both sides of the equation by 3. This cancels out the fraction on the left side, allowing us to solve for 'm'.

In step by step:

So, "the solution to the equation is m = 6".

Final answer:

A terminating decimal has a finite number of decimal places, whereas a repeating decimal has one or more digits that repeat infinitely. Trailing zeros in a decimal number are significant when they come after a decimal point, affecting precision in arithmetic operations.

Explanation:

The difference between a terminating decimal and a repeating decimal lies in their decimal expansions. A terminating decimal has a finite number of decimal places; once you write out all the decimal places, the number ends. For example, 0.5 or 0.75 are terminating decimals because they stop after one or two decimal places, respectively. On the other hand, a repeating decimal has one or more digits that repeat infinitely. For instance, 0.333... (where the 3s go on forever) is a repeating decimal. The bar above the digit(s) indicates that it repeats indefinitely.

In the context of significant figures and rounding, trailing zeros in a decimal number are significant when a decimal point is present. This precision is important in arithmetic operations. When rounding off in addition or subtraction, the number of decimal places in the result should match the number in the expression with the fewest decimal places. The same concept of precision applies to multiplication and division, where the number of significant figures must align with the term having the least amount of them.

The mean of the given data set, after removing the outlier, is 49.

To determine the mean of a data set, outliers (extremely high or low values) must first be identified and removed. Looking at the given data set: 42, 43, 46, 48, 57, 60, 96, 59, 38, 68, 29; the number 96 is an outlier as it is remarkably higher than the other values.

After removing the outlier, the rest of the data set becomes: 42, 43, 46, 48, 57, 60, 59, 38, 68, 29.

To find the mean (average), sum all these numbers and divide by the count of numbers. The total sum of these numbers is 490, and there are 10 numbers. Therefore, the mean is 49 (490 divided by 10).

The mean of the data set after removing the outliers is c. 49

From the question, we have the following parameters that can be used in our computation:

The data set

Where, we have

42, 43, 46, 48, 57, 60, 96, 59, 38, 68, 29

The outlier in the data set is 96

If we remove them, we will have the following data set:

42, 43, 46, 48, 57, 60, 59, 38, 68 and 29

The mean of this data set is calculated as follows:

mean = (42 + 43 + 46 + 48 + 57 + 60 + 59 + 38 + 68 + 29) / 10 = 49

Hence, the mean without outliers is 49

Answer:

- 4(x + 3)(x - 2)

Step-by-step explanation:

Given

- 4x + 24 - 4x² ← rewrite in standard form, that is

- 4x² - 4x + 24 ← factor out - 4 from each term

= - 4(x² + x - 6) ← factorise the quadratic

Consider the factors of the constant term (- 6) which sum to give the coefficient of the x- term (+ 1)

The factors are + 3 and - 2, since

3 × - 2 = - 6 and 3 - 2 = + 1, hence

x² + x - 6 = (x + 3)(x - 2), and

4x² - 4x + 24 = - 4(x + 3)(x - 2)

The decimal answer is 9.6568 ( round the answer as needed.)

See the attached picture:

#3 is 40 degrees Clockwise.

Answer:

4

Step-by-step explanation:

First off, integers are Whole Numbers (1,2,3,4, etc), so we are rounding the answer to the nearest whole number.

The square root of lets just say 25 means you are finding a number that multiplied by itself will equal 25 (the answer is 5).

Now for 13, there is no perfect square, however the closest whole number that multiplied by itself to 13 is 4.

4*4= 16

3*3=9

5*5=25

As you can see above 4 is the closest number to 13.

Now, the ACTUAL value of the square root of 13 is 3.60555128, but we are rounding up to the nearest whole number which is 4 :)

The square root of 13 is approximately 3.6055, but to the nearest integer (whole number), it's 4.

The question asks for the square root of 13. First, it's important to understand what a square root is. In simple terms, the square root of a number is a value that, when multiplied by itself, gives the original number. So, if you take the square root of 16, for example, it's 4 because 4 multiplied by 4 equals to 16. Now, 13 is not a perfect square, so its square root is not a whole number. If you calculate the square root of 13, you'll get an answer somewhere around 3.6055. However, the question asks for the nearest integer. An integer is a whole number, so we're looking for the whole number closest to 3.6055. In this case, it's 4. So, the square root of 13, to the nearest integer, is 4.

Sadie’s family’s car is slightly more fuel efficient than Nanette’s family’s car.

Answer:

Sadie's car is more fuel efficient.

Step-by-step explanation:

Consider the provided information.

For comparison both quantity should be same. So convert miles per gallon into kilometers per liter.

Sadie tells her family's car is getting 42 miles per gallon.

To convert miles per gallon into liters per km use the formula:

1 miles per gallon = 0.425144 kilometers per liter

Multiply both the sides by 42.

1×42 miles per gallon = 0.425144×42 kilometers per liter

42 miles per gallon = 17.856 kilometers per liter

That means Sadie's car millage is 17.856 kilometer per liter.

Nanette tells Sadie that her family’s car uses 6 liters per 100 km.

6 Liters = 100 km

Divide both sides by 6.

1 Liters = 16.66..

That means Nanette's car millage is approximately 16.67 kilometer per liter.

Hence, Sadie's car is more fuel efficient.

Answer: c=11, m=28

Step-by-step explanation:

c= Chris's score

m= Mike's score

c+m=39                 we know from the equation that their scores

                              add up to 39, so this equation is a good starting

                              point.

c+2(c+3)=39          we also know that Mike's score is twice the sum of Chris's

                              score and 3 so we can substitute that in for his score.

                              now we can solve.

c+2c+6=39             distribute

3c+6=39                 combine like terms

   -6  -6                  

3c=33                     addition property of equality

÷3  ÷3          

c=11                         multiplication property of equality

Now that we know Chris's score, we simply substitute that number in in our simple equation for earlier to find Mike's score.

11+m=39                  substituted in 11 for c

-11     -11                  

m=28                       addition property of equality

There you go! Don't worry, I had a lot of trouble with these types of problems too. That's why I'm so good at them now Hope this helps!
