Answer:
E = J, and X = 11
Step-by-step explanation:
Okay. So we know that the total degree in a triangle is 180 degrees. We see that the two triangle are similar (E = J) so J = 80, S = 36, and P = 4x +20
We can make this into the equation 80 + 36 +4x +20 = 180
We then simplify 136 + 4x = 180
Isolate 4x 4x = 180 - 136
4x = 44

Answer:
688.7
Step-by-step explanation:
Top and Bottom
Area = 3/4 * pi * r^2
r = 6
Area = 3/4 * 3.14 * 6^2
Area = 84.78
Don't round yet.
Vertical surface
Vertical surface = 3/4 * pi * d * h
d = 12 inches (the diameter)
Vertical surface = 3/4 * 3.14 * 12 * 15
Vertical surface = 423.9
Two inner faces
They are both rectangles
Area = 2 * L * W
L = 15
w=6
Area = 2 * 15 * 6 180
Total 688.68
Total = 688.7
En un estacionamiento cobran $12.00 la hora y $3.00 por 1/4 de hora ¿Cuánto debo pagar si estacione mi coche a las 11.15am y los saque a las 3.00pm
Ayuda plis doy coronita.
Answer:
$45
Step-by-step explanation:
De 11.00am a 3.00pm hay 4 horas de diferencia.
Eso seria 12x4=$48
Pero necesitamos restarle 1/4 de hora, por lo que se estaciono a las 11.15am y no a las 11.00am
1/4 de hora o 15min= $3.00
48-3=45

Find the center and radius of this
circle:
(x + 9)2+(y – 6)2= 25
Center = ([ ? ],[])
a
Radius = []
Answer:
Center= (-9,6) Radius=5
Step-by-step explanation:
correct answer:
( x + 9 ) ² + ( y - 6 ) ² = 25
center = ( -9, 6 )
radius = 5
equations:
we know from the given equation that the center would be (-9, 6) because we have to plug into the equation; ( x – h ) ² + ( y – k ) ² = radius²
how to find the center coordinates:
if youre confused on how we got the -9, by using the negative addition rules:
x - (-9) we can simplify that to ( x + 9 ) like shown above so that how we got -9. It's a little easier to find the 6 because its just x - 6 so we dont have to simplify anything its just 6.
how to find the radius:
the radius is a little more difficult to find, but, since we are given 25, we can just type the square root of 25 (√25) which would be 5!
thats it!! hope this helps<3
Please answer this math question for me
Answer:35 51 98
Step-by-step explanation:
Answer:
Hello! Thanks for posting the question again!
Anyways here are the answers...
d = 35 because its a vertical angle
e = 51 because its a vertical angle
Now to find f we have to add these up then subtract by 360 then ÷ by 2 so 51 + 51 + 35 + 35 = 172 360 - 172 = 188 188 ÷ 2 = 94 so f = 94

A bus makes a stop at 2:30, letting off 10 people and letting on 8. The bus makes another stop ten minutes later to let off 5 more people. How does the number of people on the bus after the second stop compare to the number of people on the bus before the 2:30 stop?
Answer:
7 less people
Step-by-step explanation:
You let 10 people off then you let 8 on meaning there are 2 less people. Then 5 more people get off meaning there are 7 less people

What is the vertex of the graph of the quadratic function f(x) = x2 + 6x +10?
F (3,-1)
G(-3,-1)
H(-3,1)
J(3,1)
Answer:
(-3, 1) (Answer H)
Step-by-step explanation:
f(x) = x^2 + 6x +10 can be rewritten by "completing the square" as
f(x) = (x + 3)^2 + 1, and by comparing this to y = (x - h)^2 + k, we see that h is -3, k is 1, so the vertex, (h, k), is at (-3, 1) (Answer H)

Jose desea que la puerta de su cuarto solo se pueda abrir hasta cierta posicion (ver figura). Si uno de los angulos de la abertura mide (x + 5)° y la otra (2x + 13)°. Cual seria la medida del angulo de la abertura menor?
Answer:
La medida del ángulo de la abertura menor es 29°.
Step-by-step explanation:
Podemos calcular la medida del angulo de la abertura menor hallando el valor de "x" en la siguiente ecuación:
[tex] (x + 5) + (2x + 13) = 90 [/tex] (1)
Dado que en la figura podemos observar que la suma de ambos ángulos de abertura resulta en un ángulo rectángulo.
Al resolver la ecuación (1) tenemos:
[tex] x + 2x = 90 - 13 - 5 [/tex]
[tex] 3x = 72 [/tex]
[tex] x = 24 [/tex]
Ahora, podemos encontrar los ángulos de abertura.
Angulo de abertura menor:
[tex] x + 5 = 24 + 5 = 29^{\circ} [/tex]
Angulo de abertura mayor:
[tex] 2x + 13 = 2*24 + 13 = 61^{\circ} [/tex]
Por lo tanto, la medida del ángulo de la abertura menor es 29°.

The Pythagorean Identity states that:
(sin x)2 + (cos x)2 = 1
Given sin 0 = 2/5, find cos 0.
cos O = ✓21/ [ ? ]
Simplify the fraction.
Answer:
cos (theta) = √21/5
Step-by-step explanation:
sin (theta) = 2/5
(sin (theta))^2 = 4/25
4/25 + (cos (theta))^2 = 1
(cos (theta))^2 = 1 - 4/25 = 21/25
cos (theta) = √21/5
