To determine what percent of 10 is 6, you multiply 6/10 by 100, which equals 60%, thus 6 is 60% of 10.

To find what percent of 10 is 6, we can use the formula for percentage which is (Part / Whole) * 100.

In this case, the 'part' is 6 and the 'whole' is 10.

So the equation to find the percentage is (6 / 10) * 100.

Calculating that out, we get 0.6 * 100, which equals to 60%.

Therefore, 6 is 60% of 10.

This is a basic concept in mathematics where you are trying to find out how one number compares to another in terms of percentage.

To determine the size of an angle and its supplement when the angle is four times the size of its supplement, we use the equation x = 4(180 - x) and solve for x to find that the angle measures 144 degrees and its supplement measures 36 degrees.

To find the measures of an angle and its supplement when the angle is four times its supplement, we use the expressions x and 180 - x. We can set up the equation x = 4(180 - x). Then we can solve for x to find the measures of the angle and its supplement.

By expanding and rearranging the equation, we get:

Thus, the angle measures 144 degrees and its supplement measures 36 degrees (since 180 - 144 = 36).

Answer: Option A inverse variation

Explanation:

when we  compare the values from the given  table  x is increasing and y is decreasing hence we can see it is  an inverse variation.

In option B difference among  all consecutive  values of x is 2 but in y it is not same among  all consecutive  terms. In linear function change in y over change in x must be same.

In option C  x is increasing but y is decreasing which is violating the property of logarithmic function. In logarithmic function  if  x  increases then y should increase.

In option D first value of x is 2 following quadratic property meaning giving square of itself in y which is 4. But not all values of y are square of x except first value. In quadratic function value of y should be square of x.

The type of function that best models the table given is: A. inverse variation.

Inverse variation can be described as a relationship between two variables, whereby, the product of the two variables will give a constant. It is expressed as, k = xy.

In an inverse variation, if one variable increases, the other variable decreases.

The table shows an inverse variation because as x increases, y decreases, and can be expressed as k = xy.

Therefore, the type of function that best models the table given is: A. inverse variation.

The supplementary angles are defined as when pairing of angles addition to 180° then they are called supplementary angles. There are two types of supplementary angles.

Premise: If two angles form a linear pair, they are supplementary.

If two angles are supplementary, the total of their measurements equals 180.

Conclusion: If two angles form a linear pair, the total of their measurements equals 180.

If two angles form a linear pair, they are always supplementary.

Thus, if two angles form a linear pair, the total of their measures is 180°; however, if two angles are supplementary, it does not ensure that they will form a linear pair.

So the given argument is valid by the law of syllogism.

Hence, the correct answer would be option (C).

They need to earn 7 yards on the fourth down to have a 10 yard gain from their starting position

Step-by-step explanation:

To gain a new set of downs, a football team has four downs(tries) to gain 10 net yards, in total.

Gained 6 yards on first down

Net of 6 yards gained

Needs 10-6 = 4 yards

Lost 15 yards on second down

6 - 15 = -9

In all, they have lost 9 yards, so they need

4 + 15 = 19 yards

Gained 12 yards on third down

-9 + 12 = 3 net yards(need 10)

19 - 12 = 7

They need to earn 7 yards on the fourth down to have a 10 yard gain from their starting position

The coordinates of the midpoint of the segment HK are (7, 6).

The midpoint coordinates of a line segment can be found using the midpoint formula:

Midpoint =[tex]\((\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2})\)[/tex]

Given the endpoints of the segment as H(8,2) and K(6,10), let's plug these values into the formula:

Midpoint =[tex]\((\frac{8 + 6}{2}, \frac{2 + 10}{2})\)[/tex]

Midpoint =[tex]\((\frac{14}{2}, \frac{12}{2})\)[/tex]

Midpoint =[tex]\((7, 6)\)[/tex]

The coordinates of the midpoint of the segment HK are (7, 6).

To calculate the midpoint of a line segment, you can follow these steps:

1. Identify the coordinates of the endpoints of the segment. Let's call them[tex]\( (x_1, y_1) \) and \( (x_2, y_2) \).[/tex]

2. Use the midpoint formula:[tex]\( \text{Midpoint} = \left( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} \right) \).[/tex]

3. Substitute the coordinates into the formula and calculate.

In this case, the endpoints are H(8,2) and K(6,10). Plug these values into the midpoint formula:

Midpoint = [tex]\( \left( \frac{8 + 6}{2}, \frac{2 + 10}{2} \right) \).[/tex]

Simplify the equation:

Midpoint =[tex]\( \left( \frac{14}{2}, \frac{12}{2} \right) \).[/tex]

Finally, calculate the values:

Midpoint =[tex]\( (7, 6) \).[/tex]

So, the coordinates of the midpoint of the segment HK are (7, 6).
