The following are the ages (years) of 5 people in a room:
23, 20, 15, 12, 17
A person enters the room.
The mean age of the 6 people is now 19.
What is the age of the person who entered the room?
Answer:
multiply 6 by 19 to get the total age of the six people in the room then add the ages of the 5 people in the room and subtract it from the total of the 6 to get your answer
Answer:
27
Step-by-step explanation:
The mean is calculated as
mean = [tex]\frac{sum}{count}[/tex]
let x be the age of the person entering the room , then
[tex]\frac{23+20+15+12+17+x}{6}[/tex] = 19 ( multiply both sides by 6 )
87 + x = 114 ( subtract 87 from both sides )
x = 27
The age of the person who entered the room is 27
Find the length of arc AB. Use 3.14 for pi. Round to the nearest tenth.
Answer:
arc AB = 12.40°
Step-by-step explanation:
diameter = 7.9 x 2 = 15.8
circumference = 15.8 x 3.14 = 49.612
since the central angle of arc AB is 90 °
90/360 x 49.612 = 12.40
Answer:
12.4

Given this situation:
A group of freshmen and sophomores are on a field trip. The
number of freshmen is five less than twice as many than the
number of sophomores.
If there are a total of 40 people on the field trip, how many
are freshmen and how many are sophomores?
Answer:
15 sophomores and 25 freshmen
Step-by-step explanation:
15×2 is 30, five less is 25
15+25=40
how many solutions does d+6+2d=4d+9 have?
Answer:
Only one solution
Step-by-step explanation:
d+6+2d=4d+9
3d + 6 = 4d + 9
3d - 4d = 9 - 6
-d = 3
d = - 3
Share 54 in the ratio 5:4
................................
Answer:
x = 63°
it is an isosceles triangle, so K and M are equal
Step-by-step explanation:
let K be x, since K=M means both equals x
x + x + 54° = 180°
2x + 54° = 180°
2x = 180° minus 54°
2x = 126°
x = 63°
to prove
63° + 63° + 54° = 180°

22 The distance around a meteor crater is 9,031 ft. Find the diameter of the crater. Use 22/7
(Type an integer or decimal rounded to the nearest tenth as needed.)
Answer:
d = 2873.5 feet
Step-by-step explanation:
Given that,
The distance around a meteor crater is 9,031 ft.
We need to find the diameter of the crater. The circumference of a circle is given by :
[tex]C=2\pi r[/tex]
Where
r is the radius of the circle
So,
[tex]r=\dfrac{C}{2\pi}\\\\r=\dfrac{9031}{2\times \dfrac{22}{7}}\\\\r=1436.75\ ft[/tex]
Since,
Diameter, d = 2r
[tex]d=2\times 1436.75\\\\d=2873.5\ ft[/tex]
So, the diameter of the crater is equal to 2873.5 feet.
Below are two parallel lines with a third line intersecting them

What is the slope of y=x??
Answer:
Since we know the slope is the value multiplied by x , the slope is −1.
Step-by-step explanation:
We can rewrite this equation as:
y=1x+0
The slope-intercept form of a linear equation is:
y=mx+b
Where m is the slope and b is the y-intercept value.
For this equation:
y=1x+0
Therefore:
The slope is m=1
The y-intercept is b=0 or (0,0)

Given the following polygon, find the sum of the interior angles and the value of x,
pls help
Answer:
sum of interior angles - 540
x = 112
Step-by-step explanation:
Hello There!
Geometry
The sum of the interior angles can be found using this formula
let x = sum of interior angles and n = number of sides
x = ( n - 2 ) * 180
there are 5 sides so we plug in 5 to n
5 - 2 = 3
3 * 180 = 540 so the sum of the interior angles is 540
Now to solve for x
Remember the sum of the interior angles is 540 so we use this equation to solve for x
Simple Algebra
540 = x + 118 + 105 + 75 + 130
step 1 combine like terms
118 + 105 + 75 + 130 = 428
now we have 540 = 428 + x
step 2 subtract 428 from each side
540 - 428 = 112
we're left with x = 112

Who has the greater mean absolute deviation, and by how much? Show or explain how you know.
Answer:

150*(1 - 5/8) = 150(3/8) = 56.25Option A#2
56.80 + 22.70x = 374.6022.7x = 374.60 - 56.8022.7x = 317.8x = 317.8/22.7x = 14 months#3

how do i solve 7x^{2} +11y^{2} =40
Answer:
Step-by-step explanation:
There is no solution as you have two variables and only one equation. The best you can do is solve for one variable as a function of the other.
[tex]7x^2+11y^2=40\\ \\ 11y^2=40-7x^2\\ \\ y^2=\frac{40-7x^2}{11}\\ \\ y=\sqrt{\frac{40-7x^2}{11}}[/tex]

Jimmy takes gets a student loan to go to college after high school. If he pays $9,000 in interest at a rate of 3% for 4 years, what is the principal amount borrowed?
Answer:Principal=$7,500,000
Step-by-step explanation:
Interest =(Principal X Rate X time ) / 100
Given
Interest =$9,000
rate = 3%
Time= 4 years
Principal=(Interest X 100) / rate X time
Principal,=(9000x 100)/3% x 4
Principal=$7,500,000
A matea le encanta dibujar barquitos.Si traslado su barquito inicial 1 des veces,(2 y 3) ¿Cómo desplazo cada uno de sus puntos?
Answer:
Luego de una búsqueda online, encuentre más información sobre esta pregunta, la cual se puede ver en la imagen del final.
Básicamente lo que tenemos que hacer en este tipo de problemas, es estudiar como los puntos del barco uno cambian cuando hacemos cada transformación, usualmente con un par de puntos ya podremos notar un patrón, y de esta forma entender la transformación que utilizo para mover la figura.
Para conocer las coordenadas de cada punto tenemos que ver el valor de x asociado (el eje horizontal) y el valor de y asociado (el eje horizontal), notar que cada punto está representado por una letra, esto nos permite asociar a los puntos de los distintos barcos.
Entonces, en la transformación de (1) a (2), los cambios en los puntos son:
A (1, 7) --> A₁ (11, 11) (sumamos 10 al eje x, sumamos 4 al eje y)
B (0, 9) --> B₁ (10, 13) (sumamos 10 al eje x, sumamos 4 al eje y)
C (3 , 9) --> C₁ (13, 13) (sumamos 10 al eje x, sumamos 4 al eje y)
Ok, ya con 3 puntos podemos notar un patrón, sea (x, y) un punto cualquiera en el barco (1), el correspondiente punto en el barco (2) va a ser (x + 10, y + 4), esta es la regla utilizada para mover el barco de (1) a (2), lo que es equivalente a decir que movió el barco 10 unidades a la derecha, y 4 unidades para arriba.
Ahora Mateo vuelve a mover el barco, esta vez de (2) a (3).
De vuelta, tenemos que ver como los puntos del barco (2) cambian, y tratar de encontrar un patrón:
A₁ (11, 11) --> A₂ (9, 1) (restamos 2 en el eje x, restamos 10 en el eje y)
B₁ (10, 13) --> B₂ (8, 3) (restamos 2 en el eje x, restamos 10 en el eje y)
C₁ (13, 13) --> C₂ (11, 3) (restamos 2 en el eje x, restamos 10 en el eje y)
De vuelta, ya tenemos suficiente información como para notar el patrón, para un punto (x, y) del barco (2), el correspondiente punto en el barco (3) se escribe como (x - 2, y - 10).
Es decir, movemos el barco (2) 2 unidades para la izquierda y 10 unidades para abajo, asi llegando al barco (3).
