Answer: z=22
Explanation:
9^2 + z = 103
81 + z = 103
103 - 81 = z

A circle has a diameter of 8 cm. What is the circumference? Round to
the nearest hundredth.
Answer:
C≈25.13cm
Step-by-step explanation:
C=πd=π·8≈25.13274cm
d=2r
C=2πr
(hope this helps)
Step-by-step explanation:
area of a cicle is π[tex]r^{2}[/tex]
the diameter is twice as long as the radius so the radius would have a length of 4 cm.
π[tex]4^{2}[/tex]=50.27
Hope that helps :)

In the figure shown, GD = 3x + 5, GF = 6x-4, and G is the incenter of AABC. Find GE
Answer:
GE = 14
Step-by-step explanation:
The incenter is equidistant from the sides, so GD = GE = GF.
Set the expressions for GD and GF equal to each other and solve for x.
3x + 5 = 6x - 4
5 = 3x - 4
9 = 3x
3 = x
Now plug this value into either expression, say for GD. GD = 3(3) + 5 = 14.
GE must be the same, GE = 14
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.

The measure of two angles are (3x+50) and (4x - 10). What must be true
about the angles if x = 20? What is the sum of their measures?
Answer: The two angles add up to 180 so they are supplementary angles.
The sum of their measures is 180 degrees.
Step-by-step explanation:
Plug in given value for x.
x=20
(3x+50)=
(60+50)=110
110
(4x-10)=
80-10=70
70
There are several true things about these angles you can find from this information but I think you are looking for the answer at top.

Which of these correctly rearranges the terms in this polynomial so like terms are next to each other
Question is not complete, so i have attached it.
Answer:
B: -2x² - 6x² - 6x + 3x + 3 + 2
Step-by-step explanation:
From the image attached, the given polynomial is;
3 - 6x - 2x² + 3x - 6x² + 2
For like terms to be next to each other, we have to rearrange it as follows;
-2x² - 6x² - 6x + 3x + 3 + 2
Like terms are x² and x, thus they are now arranged next to each other.

if 5 bags of sugar with equal weight weigh 35 kg, how many bags of sugar would weigh 56 kg?
Answer:
8 bags
Step-by-step explanation:
If 5 bags equal 35 kg, then each bag will weigh 35/5 or 7 kg. If there are 56 kg and you want to find the number of bags, you divide 56 by 7 and you get 8.

The radius of a circle is 17 in. Find its area in terms of π.
A≈907.92in²
Because:
A=πr2=π·172≈907.92028in²
Answer:
289π or 907.46 in
Step-by-step explanation:
The formula for area of a circle is π r².
The radius is 17, so the first step is 17².
17²= 289
Next, you multiply 289 by pi (3.14).
3.14 x 289 = 907.46.
Therefore, the area in terms of pi is 289π or 907.46 in.

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

What does Bob’s equation predict for the height of a person with an arm span of 162 cm? If entering a decimal value, round to the tenths place.
Answer:a
Step-by-step explanation:
Answer:
y = (10/9)x - 138/9
Height of 164.7 cm for an arm span of 162 cm
Step-by-step explanation:
First we find the slope. (178 - 168)/(174 - 165) = 10/9
Now use the point-slope form of a line
y - 168 = 10/9(x - 165)
9y - 9(168) = 10(x - 165)
9y - 1512 = 10x - 1650
9y = 10x - 138
y = (10/9)x - 138/9
If the arm span is 162 cm, then x = 162
y = (10/9)(162) -138/9
= 180 - 15.3
= 164.7 cm

7/3 + x=3;x math I really need help
Given:
The equation is:
[tex]\dfrac{7}{3}+x=3[/tex]
To find:
The value of x.
Solution:
We have,
[tex]\dfrac{7}{3}+x=3[/tex]
Subtract both sides by [tex]\dfrac{7}{3}[/tex].
[tex]\dfrac{7}{3}+x-\dfrac{7}{3}=3-\dfrac{7}{3}[/tex]
[tex]x=\dfrac{9-7}{3}[/tex]
[tex]x=\dfrac{2}{3}[/tex]
Therefore, the value of x is [tex]\dfrac{2}{3}[/tex] or it can be written as 0.667.
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°
