Answer:
The age of the person who entered the room is 27
Step-by-step explanation:
If there are 6 people and the mean is 19 you would need to multiply 19 by 6. You will get 114 and now you just subtract the age of the others. 114-23-20-15-12-17=27.

The grass in Jamie's yard grew 161616 centimeters in 101010 days. It was growing at a constant rate.
How many days did it take the grass to grow 111 centimeter?
days
How many centimeters did the grass grow in 111 day?
centimeters
Days it took the grass to grow 1 centimeter and centimeters the grass grew in 1 day
0.625 days to grow 1 cm.
16/10 = 1.6 cm in 1 day.
How many centimeters did the grass grow in 111 days?According to the law of proportion, any two ratios or fractions must be equal.
In only a week and a half, the grass in Jamie's backyard grew by 16 cm. it is expanding at an unchanging pace.
We need to determine how many days have passed since the grass has grown one centimeter.
Let's say that x represents the number of days that the grass grew one centimeter.
Given the following definition of proportion:
16/10=1/x
16x = 10
x = 0.625 days
As a result, one centimeter of grass growth occurred after 0.625 days had passed.
b)
Change x into 1. Because x is the number of days.
16/10=1/1

For many years after the war, various individuals and groups sought compensation for the internees. The speed of the evacuation forced many homeowners and businessmen to sell out quickly; total property loss is estimated at $1.3 billion, and net income loss at $2.7 billion (calculated in 1983 dollars based on the Commission investigation below).
The Japanese American Evacuation Claims Act of 1948, with amendments in 1951 and 1965, provided token payments for some property losses. More serious efforts to make amends took place in the early 1980s, when the congressionally established Commission on Wartime Relocation and Internment of Civilians held investigations and made recommendations. As a result, several bills were introduced in Congress from 1984 until 1988, when Public Law 100-383, which acknowledged the injustice of the internment, apologized for it, and provided for restitution, was passed. –Documents from the National Archives: Internment of Japanese Americans According to this source, what was the result of the commission?

abc is right angled triangle,
A triangle in which one of the interior angles is 90° is called a right angled triangle.
The longest side of a right triangle, which is also the side opposite the right angle, is the hypotenuse.The two arms of the right angle triangle are the height and the base.According to the diagram 'ab' is the height or perpendicular 'ac' is the base and 'bc' is the hypotenuse of the triangle.
Sin θ = [tex]\frac{perpendicular}{hypotenuse}[/tex]
Cos θ = [tex]\frac{base}{hypotenuse}[/tex]
Tan θ = [tex]\frac{perpendicular}{base}[/tex]
Cosine angle at b will be represented as Cos b = [tex]\frac{base}{hypotenuse}[/tex] = [tex]\frac{ab}{bc}[/tex]
the base considered for the angle at 'b' will be 'ab' since Cosine uses the base attached to the angle.
Sine angle at c will be represented as Sin c = [tex]\frac{perpendicular}{hypotenuse}[/tex] = [tex]\frac{ab}{bc}[/tex]
the perpendicular considered for the angle at 'c' will be 'ab' since Sine uses the perpendicular which lies opposite to the angle considered.

How do I graph y+4=5x?
To graph a linear equation, including the function y + 4 = 5 · x, we needed to rewrite the equation into its explicit form, mark two distinct points on a Cartesian plane and pass a line through them. The result is presented in the image attached below.
How to graph a linear equationHerein we find a linear equation in a non-canonical form and to which we are asked to graph. According to geometry, lines can be created by knowing the location of two distinct points on Cartesian plane. The detailed procedure is now shown.
First, clear the variable y to obtain the explicit form of the linear equation:
y = 5 · x + 4
Second, look up for two distinct points on Cartesian plane by evaluating the expression at distinct values of x:
x = 0
y = 5 · 0 + 4
y = 4
x = 1
y = 5 · 1 + 4
y = 9

Step-by-step explanation:
The x-intercept is when the line crosses the x-axis, so when y = 0.
Therefore, the two points on the line are:
(1, 0)(-1, -4)To find the equation of the line when given two points from the line, first find the slope:
[tex]\textsf{slope}\:(m)=\dfrac{\textsf{change in $y$}}{\textsf{change in $x$}}=\dfrac{-4-0}{-1-1}=2[/tex]
Now substitute the found slope and one of the points (1, 0) into the point-slope form of a linear equation:
[tex]\implies y-y_1=m(x-x_1)[/tex]
[tex]\implies y-0=2(x-1)[/tex]

Write each expression in simplest form. (3x²/₃)⁻¹
The given expression would be simplified by solving for the negative exponent.
In this expression, the base term is 3x^2/3 and the exponent is -1.
A positive exponent tells us how many times a number is multiplied by itself while the negative exponent tells us how many times the base number has to be divided. It can also be described as the number of times the reciprocal of the base number is multiplied by itself.
The negative exponent rule states that: a^-x=1/a^x
Hence, applying the rule:
(3x^²/₃)^-1=1/(3x^²/₃)^1
Multiplying the power and simplifying,
1/(3x^²/₃)^1=1/3^1x^²/₃*1=1/3x^²/₃
The simplest form of the expression (3x^²/₃)^-1 is 1/3x^²/₃.
