Answer:

308.65 Pounds

Step-by-step explanation:

Since one kilogram is 2.20462 pounds you can multiply 140 by 2.20462 to get 308.6468 and rounded to the nearest hundredth it would be 308.65.

The weight of a 140 kilogram person in pounds is approximately 308.64 pounds, when rounded to the nearest hundredth.

To find the weight of a 140-kilogram person in pounds, we first need to understand that weight is a measure of the force of gravity on an object and can be calculated by multiplying the mass of the object by the acceleration due to gravity.

However, here, we are converting kilograms to pounds, which is a conversion of mass units, not weight. The conversion factor from kilograms to pounds is approximately 2.2046.

Therefore, to convert 140 kilograms into pounds, we multiply 140 by 2.2046:

140 kg * 2.2046 = 308.644 pounds.

And rounded to the nearest hundredth, we get 308.64 pounds.

The closing bracket ']' in the inequality solution set (–∞, 6.5] indicates that 6.5 is included, making it a solution to the inequality.

The solution to an inequality is (–∞, 6.5]. To determine if 6.5 is a solution to the inequality, we look at the notation used. The parenthesis '(' indicates that the number at this end of the interval is not included in the solution set, while the bracket ']' indicates that the number at this end is included. Since 6.5 is associated with a closing bracket, it means that 6.5 is indeed a solution to the inequality. Therefore, any number less than or equal to 6.5 is a solution to this particular inequality.

The correct explanation among the given options is the following:

"The solution includes numbers from negative infinity to 6.5. Because a bracket is used, the solution includes 6.5."

In interval notation, brackets ([ and ]) indicate that the endpoint is included in the solution, while parentheses (( and )) indicate that the endpoint is not included.

Here, with (-∞, 6.5], the closing bracket means 6.5 is included in the solution to the inequality.

Thus, 6.5 is a valid solution to the inequality.

The complete question is : The solution to an inequality is (-, 6.5]. Is 6.5 a solution to the inequality? Explain your answer

The solution includes numbers from negative infinity to 6.5. Because a bracket is used, the salution does not

include 6.5. The solution includes numbers from 6.5 to infinity. Because a parenthesis is used, the solution does not include 6.5.

The solution is the point(, 6.5). Because a bracket is used, 6.5 is a solution to the inequality.

The solution includes numbers from negative infinity to 6.5. Because a bracket is used, the solution includes 6.5.

Answer:

B) 9.2

Step-by-step explanation:

To find an average, you have to combine all of your numbers and then divide by how many there are.

So first, combine the values.

9.7 + 8.6 + 9.3 = 27.6

Now, divide by how many numbers you had, which is 3.

27.6 ÷ 3 = 9.2

Firstly , combine the all values

[tex]9.7 + 8.6 + 9.3 = 27.6[/tex]

Now , divided by 3

[tex] 27.6 \div 3 \\ \\ \frac{27.6}{3} \\ \\ 9.2 [/tex]

The correct answer is 9.2 - option (b) (✔)

To solve this you must use a proportion like so...

[tex]\frac{part}{whole} = \frac{part}{whole}[/tex]

60 is a percent and percents are always taken out of the 100. This means that one proportion will have 60 as the part and 100 as the whole

We want to know out of what number is 12 60%. This means 12 is the part and the unknown (let's make this x) is the whole

[tex]\frac{12}{x} =\frac{60}{100}[/tex]

Now you must cross multiply

12*100 = 60*x

1200 = 60x

To isolate x divide 60 to both sides

1200/60 = 60x/60

20 = x

This means that 60% of 20 is 12

A Quadratic Equation can have upto 2 roots maximum. So,if one of the roots is a Real number, there are following two possibilities:

1) The other root is also a real number, but a different number

2) Its a repeated root, so the other root is the same number.

The other root cannot be a complex number as its not possible for one root to be real and other to be complex. Either no root will be complex or both will be complex roots.

Step-by-step explanation:

To find a significant figure you just count how many numbers are before and after the decimal place but if the first number is zero then it does not count.

Final answer:

The values with 3 significant figures are A. 10.1 and D. 129, as non-zero numbers are always significant, and there are no leading, captive, or trailing zeros to consider in these cases.

Explanation:

The values that have 3 significant figures are:

A. 10.1

D. 129

In A, all the digits are significant because they are all non-zero numbers. In D, similarly, all digits are significant since non-zero numbers are always counted as significant figures.

For the options not chosen:

B. 100.05 has 5 significant figures because zeros between non-zero numbers are significant and so are the ending non-zero numbers.

C. 120 may be seen as having 2 or 3 significant figures depending on whether the zero is considered significant; additional context such as writing the number in scientific notation or a decimal point (120.) is needed to clarify its significance.

[tex]x<-2\\\\y\leq-x-2[/tex]

Step-by-step explanation:

From the given graph , the shaded region is bounded by two lines ( one is dotted and another is solid line).

Dotted line :  It is parallel to y-axis and intersecting the x -axis at .

so the equation of the line is x=-2.

But it is represented in dotted form it means the inequality sign used here is strictly less than.

i.e. the equation for dotted line = [tex]x<-2[/tex]

Solid line : It is passing through (-2,0) and (-1,-1).

Equation of line passing through (a,b) and (c,d) :-

[tex](y-a)=\dfrac{d-b}{c-a}(x-b)[/tex]

Then equation of sold line:

[tex](y-0)=\dfrac{-1-0}{-1-(-2)}(x-(-2))\\\\\Rightarrow\ y=\dfrac{-1}{-1+2}(x+2)\\\\\Rightarrow\ y=\dfrac{-1}{1}(x+2)\\\\\Rightarrow\ y=-x-2[/tex]

Hence, the inequality represents solid line(≤)= [tex]y\leq-x-2[/tex]

Hence, the system of linear inequalities is graphed will be :-

[tex]\textbf{$\left[\begin{array}{cc}x & y\\-3 & 12\\-6 & 24\\-9 & 36\end{array}\right]$}[/tex]

Two variables have a proportional relationship if the ratios are equivalent. In other words, in this type of cases two quantities vary directly with each other, so we can write this in a mathematical language as follows:

[tex]y=kx[/tex]

Here [tex]k[/tex] is the slope of the linear equation defined above. So, verifying that k is constant we have:

[tex]k=\frac{24-12}{-6-(-3))}=\frac{36-24}{-9-(-6)}=\frac{36-12}{-9-(-3)}=-4 \\ \\ \therefore \boxed{k=-4}[/tex]

One way to prove this is by writing the equation that represents the table. From the two-point intercept form of the equation of a line we have:

[tex]y-y_{1}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}(x-x_{1}) \\ \\ P(x_{1},y_{1})=P(-3,12) \\ \\ P(x_{2},y_{2})=P(-6,24) \\ \\ Subtituting \ x_{1}, x_{2}, y_{1}, y_{2}: \\ \\ y-12=\frac{24-12}{-6-(-3)}(x-(-3)) \\ \\ y-12=-4(x+3) \\ \\ Solving: \\ \\ y-12=-4x-12 \\ \\ Adding \ 12 \ to \ both \ sides: \\ \\ y-12+12=-4x-12+12 \\ \\ \boxed{y=-4x}[/tex]

So, this implies that the ordered pairs of the last option represent a proportional relationship

Answer:

Step-by-step explanation:

In this case, an proportional realtionship refer to the existence of a contant ratio of change between variables, that is, each y-value can be found by multiplying each x-value with this constant ratio of change.

So, notice that in the first table, is we multiply by four, you can get the first two pairs, but the last one doesn't fall into the ratio. That's not the answer.

Similarly, the second table doesn't have a constant ratio of change, because the last pair has different ratio.

However, the last table shows a constant ratio of change, because each x-value can be multiplied by -4, to get each y-value, that is

-3 x -4 = 12

-6 x -4 = 24

-9 x -4 = 36

Therefore, the right answer is the last table.

Answer:

no

Step-by-step explanation:

to know if a number is divisible by 4, you need to look only at the last two digits and see if that is divisible, 15 is not divisible by 4 and therefore the whole number isnt.

if you tried to divided 262,015 by 4 you would get 65503.75, a decimial so not divisible

Answer:

No, 262,015 will not divide evenly into 4.

Step-by-step explanation:

262,015 ÷ 4 = 65503.75.

Therefore, it will not divide evenly into 4.

Another way to do this is to check if the last two digits are divisible by 4.

The last two digits are 15. 15 is not divisible by 4. Therefore, the entire number will not be divisible by 4.
