Eli's bedroom door is 9 feet tall and 3 feet wide. A new door is $4.00 per square foot. How much would a new bedroom door cost in total
Answer:$108
Step-by-step explanation:
Given
Bedroom door is [tex]9\ ft[/tex] tall
width of the door is [tex]3\ ft[/tex]
Rate [tex]R=\$4/ m^2[/tex]
The area of the door is [tex]l\times w[/tex]
[tex]\Rightarrow A=9\times 3=27\ m^2[/tex]
Cost is given by
[tex]\Rightarrow C=27\times 4=\$108[/tex]

Answer:
2nd option
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- [tex]\frac{3}{2}[/tex], 0) and (x₂, y₂ ) = (0, [tex]\frac{3}{4}[/tex] )
m = [tex]\frac{\frac{3}{4}-0 }{0+\frac{3}{2} }[/tex] = [tex]\frac{\frac{3}{4} }{\frac{3}{2} }[/tex] = [tex]\frac{1}{2}[/tex] and c = [tex]\frac{3}{4}[/tex] , then
y = [tex]\frac{1}{2}[/tex] x + [tex]\frac{3}{4}[/tex] ( multiply through by 4 to clear the fractions )
4y = 2x + 3 ( subtract 4y from both sides )
0 = 2x - 4y + 3 , that is
2x - 4y + 3 = 0 ← equation of line

Answer:
53 and 118
Step-by-step explanation:
Just know that all the angles in a triangle add up to 180 degrees. In the first one, you can tell it is a right triangle by the square in the corner and the other angle is 37. So 180-(37+90)=53
For the second one, it is the same case so 180-(42+20)= 118
Answer:
53 degrees
Step-by-step explanation:
sum of angles in a triangle is 180
a right angle is 90
missing angle is B
180 = 90 + 37 + B
180 = 127 + B
B = 53

RULER AND COMPASSES?
(a) (b) 85 (c) 15 (d) 135
The exterior angles of a pentagon are (m+5)°, (2m+3)°, (3m+2)°, (4m+1)° and (5m+4)° respectively. Find the measure of each angle.
Answer:
Step-by-step explanation:
Sum of exterior angles of any polygon =360°
Sum of exterior angles of polygon = 360°
m + 5 + 2m + 3 + 3m + 2 + 4m + 1 + 5m + 4 = 360
m + 2m + 3m + 4m + 5m + 5 + 3 + 2 + 1 + 4 = 360 {Combine like terms}
15m + 15 = 360 {Subtract 15 from both sides}
15m = 360 - 15
15m = 345 {Divide both sides by 15}
m = 345/15
m = 23
m + 5 = 23 + 5 = 28°
2m + 3 = 2*23 + 3 = 46 + 3 = 49°
3m + 2 = 3*23 + 2 = 69 + 2 = 71°
4m + 1 = 4*23 + 1 = 92 + 1 = 93°
5m + 4 = 5*23 + 4 = 115 + 4 = 119°
Answer:
see explanation
Step-by-step explanation:
The sum of the exterior angles of a polygon = 360°
Sum the angles and equate to 360
m + 5 + 2m + 3 + 3m + 2 + 4m + 1 + 5m + 4 = 360, that is
15m + 15 = 360 ( subtract 15 from both sides )
15m = 345 ( divide both sides by 15 )
m = 23
Then
m + 5 = 23 + 5 = 28°
2m + 3 = 2(23) + 3 = 46 + 3 = 49°
3m + 2 = 3(23) + 2 = 69 + 2 = 71°
4m + 1 = 4(23) + 1 = 92 + 1 = 93°
5m + 4 = 5(23) + 4 = 115 + 4 = 119°

The graph shows the volume of ice cubes versus temperature in degrees
Celsius. Whiclestatement is false?
A. The data show a negative linear relationship.
B. Volume is the explanatory variable.
C. Temperature is strongly correlated to the volume of ice cubes.
D. The correlation coefficient is close to -1.
Answer:
A. The data show a negative linear relationship.
Step-by-step explanation:
According to the attached image as we can see that the temperature is in Y axis and volume of ice cubes is in X axis
So the following statements considered to be true
a. The volume represents the explanatory variable
b. Temperature would be strongly correlated to the ice cubes volume
c. As the correlation coefficient is near to -1
But it does not show the negative linear relationship
Therefore the correct option is a.

Considere un proceso industrial en el que se producen vigas de acero las cuales pueden tener defectos de dureza y peso. En el caso de un defecto en la dureza requiere de un estudio de laboratorio. Sin embargo, de procesos anteriores se sabe que 12% de las vigas no pasan la prueba de dureza, que 7% no pasan la prueba de pesado y que sólo 0.5% no pasan ninguna de las dos pruebas.
Si en el proceso se elige una viga al azar y una medición rápida identifica que no pasa la prueba de dureza, ¿cuál es la probabilidad de que el pesado no sea el correcto?

La inferencia estadística comprende dos partes principales, a saber: la estimación de parámetros y la prueba o docimasia de hipótesis. En este capítulo estudiaremos la segunda de ellas, con el fin de desarrollar métodos y observar su aplicación a problemas corrientes de la vida diaria. La inferencia estadística está basada en el supuesto de tomar muchas muestras, todas con igual probabilidad de ser seleccionadas y a través de una de ellas sabremos algo acerca de la población, mediante el cálculo de estimadores, que nos permitan hacer aseveraciones, incorrectas algunas veces, estableciéndose la probabilidad de error. Este método se basa en la aplicación de técnicas de muestreo, para lo cual se requiere de un buen diseño, además de la aplicación de métodos aleatorios de selección, cuando las probabilidades son iguales para cada elemento de una población. En algunos casos no requieren ser iguales, siempre que se conozcan y sean diferentes a cero. CONTENIDO Conceptos generales, usos y procedimientos de aplicación.

Two angles of a quadrilateral measure 110° and 120°. The other two angles are in a ratio of
3:10. What are the measures of those two angles?
Answer:
30, 130
Step-by-step explanation:
sum of internal angles in a quadrilateral is 360.
sum of other two angles
[tex] = 360 - (120 + 110) \\ = 360 - 230 \\ = 130[/tex]
The cost of 2 jackets and 3 skirts was sh 1800. After the cost of a jacket and that of a skirt was increased by 20%,the cost of 6 jackets and 2 skirts was sh4800,what is the new cost of a jacket and that of a skirt
Answer:
New cost of jacket = [tex]1.2x=1.2\times 600=720\ \text{sh}[/tex]
New costs of skirt = [tex]1.2y=1.2\times 200=240\ \text{sh}[/tex]
Step-by-step explanation:
Let original cost of jacket = [tex]x[/tex]
original cost of skirt = [tex]y[/tex]
The equation will be
[tex]2x+3y=1800[/tex]
New cost of jacket = [tex]1.2x[/tex]
New costs of skirt = [tex]1.2y[/tex]
The equation will be
[tex]6(1.2x)+2(1.2y)=4800\\\Rightarrow 7.2x+2.4y=4800[/tex]
The equations are
[tex]2x+3y=1800[/tex] [tex]\times 0.8[/tex]
[tex]7.2x+2.4y=4800[/tex]
[tex]1.6x+2.4y=1440[/tex]
[tex]7.2x+2.4y=4800[/tex]
Subtracting the above two equations we get
[tex]-5.6x=-3360\\\Rightarrow x=\dfrac{3360}{5.6}\\\Rightarrow x=600[/tex]
[tex]7.2\times 600+2.4y=4800\\\Rightarrow y=\dfrac{4800-7.2\times 600}{2.4}\\\Rightarrow y=200[/tex]
New cost of jacket = [tex]1.2x=1.2\times 600=720\ \text{sh}[/tex]
New costs of skirt = [tex]1.2y=1.2\times 200=240\ \text{sh}[/tex].

Mark is increasing his exercise routine by running and walking at least 4 miles each day. His goal is to burn a minimum of 1,500 calories from this exercise. Walking burns 270 calories/mile and running burns 650 calories. Could he meet his goal by walking 3 miles and running 1 mile?
Answer:
No
Step-by-step explanation:
1. (270 * 3) + (650 * 1)
2. 810 + 650
3. 1,460 miles. Therefore, by doing this, Mark would have trekked 1,460 miles.
4. 1500 > 1460, so Mark would not meet his goal by doing this.
