D) x ≈ 6.65

Answer:

fast multiply 5 by 39 to get the total age of the five people now as you are told those per 5 so imagine the six person being you if you enter you're going to add to their ages so they mean is going to be for six people so take the six people x their mean age now we have two different total ages for the five people and for the six people subtract the total age of the 5 from the 6th total ages to get the age of the person who entered the room if you don't understand please ask me and be willing to help

Answer:

The age of the person who entered the room is 21.

Step-by-step explanation:

Mean of 5 peoples = 39

i.e.

Sum / 5 = 39

Sum = 39 x 5

Sum = 195

Mean after one person enters the room = 36

Let x be the age of the new person.

Then

Mean = (Sum + x)/ 6

36 = (195 + x)/6

36 x 6 = 195 + x

216 = 195 + x

x = 216 - 195

x = 21

Answer:

L- 23

P-53

O-28

U-43

H-58

Step-by-step explanation:

For this question you must simply replace N in the equation with the number in every letter for example L is 23 because a = 5 x (4) + 3, thus these are your answers!

Answer:

n=4   a=23

n=10  a=53

n=5   a=28

n=8   a=43

n=11   a=58

Answer:

[tex]40\frac{5}{8}mm^2[/tex]

Step-by-step explanation:

To find the area of a triangle, one must use the formula,

[tex]\frac{base*height}{2}[/tex]

It is given that

- base = [tex]9\frac{3}{4}[/tex]

-height = [tex]8\frac{1}{3}[/tex]

Substitute in the values and solve;

[tex]\frac{9\frac{3}{4}*8\frac{1}{3}}{2}[/tex]

In order to multiply the two fractions, one must convert them from mixed number form to improper fraction form. This can be done by multiplying the denominator (the number under the fraction bar), by the "number" part of the mixed number, and then adding the result to the numerator (the number over the fraction bar;

- base = [tex]9\frac{3}{4}=\frac{(9*4)+3}{4}=\frac{36+3}{4}=\frac{39}{4}[/tex]

- height = [tex]8\frac{1}{3}=\frac{(8*3)+1}{3}=\frac{24+1}{3}=\frac{25}{3}[/tex]

Substitute,

[tex]\frac{\frac{39}{4}*\frac{25}{3}}{2}[/tex]

Cross simplify,

[tex]\frac{\frac{325}{4}}{2}[/tex]

Further simplify,

[tex]\frac{325}{4}*\frac{1}{2}\\\\= \frac{325}{8}[/tex]

Convert back to a mixed number divide the numerator by the denominator, write the whole-number result as the number outside of the fraction, and the remainder as the numerator of the fraction,

[tex]40\frac{5}{8}[/tex]

Answer: There is no polygon with the sum of the measures of the interior angles of a polygon is 1920°.

Step-by-step explanation:

The sum of the measures of interior angles of a polygon with [tex]n[/tex] sides is given by:-

[tex](n-2)\times180^{\circ}[/tex]

Given: The sum of the measures of the interior angles of a polygon is 1920°.

i.e. [tex](n-2)\times180^{\circ}=1920^{\circ}[/tex]

[tex]n-2=\dfrac{1920}{180}\\\\ n= \dfrac{1920}{180}+2\\\\ n=\dfrac{2280}{180}=12.67[/tex]

But number of sides cannot be in decimal.

Hence, there is no polygon with the sum of the measures of the interior angles of a polygon is 1920°.

Answer: Option 2 because it's the only one with repeating x coordinates.

Answer:

72 mins

Step-by-step explanation:

The number of minutes Sam spent on exercising is 72 minutes. Therefore, option B is the correct answer.

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

The given function is y = -0.78x + 95

Let x be the number of minutes of television Sam watched each day and y the number of minutes she spent exercising.

Here, x=30

Substitute x=30 in the given function, we get

y = -0.78(30)+95

= -23.4+95

= 71.6

≈ 72 minutes

Therefore, option B is the correct answer.
