similarity of right angle triangle
Answer:
The triangles pictured are similar (SSS), that is the corresponding sides are in the same ratio. Hence the matching angles are the same. For any right-angled triangle similar to triangle ABC, the ratio of the matching sides will be the same.
Write 24 as the product of two factors. One of the factors should be a sum.

Resolver las siguientes inecuaciones cuadráticas y presentar el conjunto solución en forma de intervalo y gráficamente. 1) X2 < 10 – 3x 2) 2x2 + 3x ≥ 2
Respuesta:
1) (-5,2)
2) [tex](-\infty,-2]U(\frac{1}{2},\infty)[/tex]
Explicación paso a paso:
1)
[tex]x^{2}<10-3x[/tex]
Para comenzar este problema, debemos moverlo todo al lado izquierdo de la inecuación, por lo que obtenemos:
[tex]x^{2}+3x-10<0[/tex]
Ahora podemos factorizar el lado izquierdo para obtener:
[tex](x+5)(x-2)<0[/tex]
Ahora podemos cambiar el símbolo < por un = para encontrar los valores de x en los cuales la inecuación es igual a cero.
(x+5)(x-2)=0
Y luego despejamos x.
x+5=0
x=-5
y
x-2=0
x=2
Ahora construimos nuestros intervalos posibles.
[tex](-\infty,-5)[/tex]
(-5,2)
y
[tex](2,\infty)[/tex]
Y escogemos algunos valores de prueba. Estos nos ayudarán a determinar si cada intervalo hace que la inecuación sea verdadera o falsa.
[tex](-\infty,-5)[/tex]
Para este intervalo escojamos -6 y evaluemoslo en la inecuación.
(x+5)(x-2)<0
(-6+5)(-6-2)<0
(-1)(-8)<0
8<0
falso, así que este intervalo no es parte de nuestra respuesta.
(-5,2)
para este escojamos x=0 y probémoslo en la inecuación.
(x+5)(x-2)<0
(0+5)(0-2)<0
(5)(-2)<0
-10<0
verdadero, así que este intervalo es parte de nuestra respuesta.
[tex](2,\infty)[/tex]
Para este escojamos 3 y probémoslo en unestra inecuación.
(x+5)(x-2)<0
(3+5)(3-2)<0
(8)(1)<0
8<0
falso, así que este intervalo no es parte de nuestra respuesta.
así que nuestra respuesta es: (-5,2)
Vea imagen adjunta para representación gráfica.
2)
[tex]2x^{2}+3x\geq2[/tex]
Para resolver este problema, comenzamos moviéndolo todo al lado izquierdo de la inecuación.
[tex]2x^{2}+3x-2\geq0[/tex]
Ahora podemos factorizar el lado izquierdo de la inecuación para obtener:
[tex](2x-1)(x+2)\geq0[/tex]
Ahora podemos cambién el símbolo ≥ por un símbolop de = para obtener los valores de x que hacen que la inecuación sea igual a 0.
(2x-1)(x+2)=0
y ahora despejamos x.
2x-1=0
[tex]x=\frac{1}{2}[/tex]
y
x+2=0
x=-2
Ahora construimos nuestros intervalos posible.
[tex](-\infty,-2][/tex]
[tex][-2,\frac{1}{2}][/tex]
y
[tex][\frac{1}{2},\infty)[/tex]
Ahora escogemos los valores de prueba correspondientes.
[tex](-\infty,-2][/tex]
para este, escojamos -3 y probémoslo en la inecuación.
[tex](2x-1)(x+2)\geq0[/tex]
[tex](2(-3)-1)(-3+2)\geq0[/tex]
[tex](-7)(-1)\geq0[/tex]
[tex]7\geq0[/tex]
verdadero, así que este intervalo es parte de nuestra respuesta.
[tex][-2,\frac{1}{2}][/tex]
para este, utilicemos 0 como valor de prueba.
[tex](2x-1)(x+2)\geq0[/tex]
[tex](2(0)-1)(0+2)\geq0[/tex]
[tex](-1)(2)\geq0[/tex]
[tex]-2\geq0[/tex]
falso, así que este intervalo no es parte de nuestra respuesta.
[tex][\frac{1}{2},\infty)[/tex]
para este, utilicemos 1 como valor de prueba.
[tex](2x-1)(x+2)\geq0[/tex]
[tex](2(1)-1)(1+2)\geq0[/tex]
[tex](1)(3)\geq0[/tex]
[tex]3\geq0[/tex]
verdadero, así que este intervalo es parte de nuestra respuesta.
Así que nuestra respuesta es la unión entre los dos intervalos que resultaron verdadero, por lo que nuestra respuesta es:

The large sphere has a diameter of 20 feet. Which expression represents the volume, in cubic units, of the shaded part of the sphere? 4f 0 (106) + M4 ㅇ (10) - [4) ㅇ (20) + (4) ㅇ (20) - (43)
Answer:
it would be (10)- (4)
Step-by-step explanation:
The expression for the volume of the shaded part of the sphere is (4/3)π(10)³, or 4,188.7902 cubic feet.
What is diameter?Diameter is a straight line passing through the centre of a circle or other safe, or the length of first as millimetre centimetre inches and feet.
here, we have,
The expression that represents the volume of the shaded part of the sphere is (4/3)πr³,
where r is the radius of the sphere,
which is 10 feet (1/2 the diameter).
Therefore, the expression for the volume of the shaded part of the sphere is
(4/3)π(10)³,
or 4,188.7902 cubic feet.
Hence, The expression for the volume of the shaded part of the sphere is (4/3)π(10)³, or 4,188.7902 cubic feet.

Which statement is true?
A.
The situation can be modeled by an exponential decay function with a percent change of -10%.
B.
The situation can be modeled by an exponential growth function with a percent change of 11%.
C.
The situation can be modeled by an exponential decay function with a percent change of -11%.
D.
The situation can be modeled by an exponential growth function with a percent change of 10%.
The situation can be modeled by an exponential decay function with a percent change of -10%, option A is correct.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
The ratio between the value after 1 year and the value after 0 years is 18,000/20,000 = 0.9.
The ratio between the value after 2 years and the value after 1 year is 16,200/18,000 = 0.9.
The ratio between the value after 3 years and the value after 2 years is 14,580/16,200 = 0.9.
Since the ratio between consecutive values is constant and less than 1, we can conclude that the situation can be modeled by an exponential decay function.
r = (18,000/20,000) - 1 = -0.1
So the percent change per year is -10%, which means that statement A is true.
Hence, the situation can be modeled by an exponential decay function with a percent change of -10%, option A is correct.

Jordan places two boards end to end to make one shelf. The first board is 47/100 meter long, the second board is 5/10 meter long. What is the total length, in meters, of the two boards?
A. 9 7/10
B. 5 2/10
C. 97/100
D. 52/100
Please help ASAP!
Answer:
97/100 meters
Step-by-step explanation:
here's the link
=> the measure of first board = 47/100 meters
=> the measure of second board = 5/10 meters
=> total length = 47/100 + 5/10
=> length = (47+50)/100
=> length = 97/100 meters

Step-by-step explanation:
A is wrong, because the standard deviation is +/-0.15 (the measure up or down from the mean)
B is wrong, because the mean is exactly 0.5
C is wrong, because 1 standard deviation up from the mean is 0.65, and 0.7 is outside of that.

Answer:
more than half are being used
Step-by-step explanation:
Perhaps easiest to understand is the most straightforward: figure the total number of seats and the number of seats being used. Check to see if that is more than half.
The 1 first-class carriage has usage of ...
(3/8)(64 seats) = 24 seats.
The 6 standard carriages have usage of ...
(7/13)(6 · 78 seats) = 252 seats.
The total number of seats used is ...
24 + 252 = 276 . . . . seats used
__
The total number of seats on the train is ...
1·64 +6·78 = 532 . . . . seats on the train
Half of the seats on the train will be ...
532/2 = 266 seats . . . . half the seats
The 276 used seats are more than half of the total number. More than half the seats are being used.
_____
Alternate solution
Another way to look at this is to compare utilization to 1/2 in each carriage class.
In first class 1/2 -3/8 = 1/8 of 64 seats = 8 seats fewer than 1/2 the seats are being used.
In standard class, 7/13 -1/2 = 14/26 -13/26 = 1/26 of 78 seats = 3 seats more than 1/2 the seats are being used. There are 6 standard class carriages, so 6·3 = 18 more than half the seats in the standard-class carriages are being used.
This number is 10 more than the 8 under-utilized seats in first class, so more than half the train seats are being used.
