hey can someone tell me why 132 is wrong? and help me with the right answer pls
Answer:
∠CBA = 132
Step-by-step explanation:
Bisectors split up an angle into two identical angles
Thus, 7x - 11 = 2x + 44
This is the equation we will use to solve for x
7x - 11 = 2x + 44
step 1 add 44 to each side
44 + 11 = 55
-11 + 11 cancels out
we now have 7x = 2x + 55
step 2 subtract 2x from each side
7x - 2x = 5x
2x - 2x cancels out
we now have 5x = 55
step 3 divide each side by 5
5x / 5 = x
55 / 5 = 11
we're left with x = 11
The question is asking for the measure of ∠CBA
To find the measure of ∠CBA we plug in 11 for x in one of the given expressions and multiply that by 2 ( this is because the two angles are identical so there is no need to find the measures of both because ∠CBD≅∠ABD )
7(11) - 11
7 * 11 = 77
77 - 11 = 66
66 * 2 = 132
a A Straight line passes through A(-2,1) and B(2,-k). The
line is perpendicular to a line 3y+2x=5 . determine k
Given :
A Straight line passes through A(-2,1) and B(2,-k).
The line is perpendicular to a line 3y+2x=5 .
To Find :
The value of k.
Solution :
Let, slope of line is m.
We know, product of slope of in straight line is -1.
[tex]m \times \dfrac{-2}{3} = -1\\\\m = \dfrac{3}{2}[/tex]
We know, slope is given by :
[tex]\dfrac{y_2-y_1}{x_2-x_1} = \dfrac{3}{2}\\\\\dfrac{1-(-k)}{-2 - 2} = \dfrac{3}{2}\\\\\dfrac{1+k}{-4} = \dfrac{3}{2}\\\\k = -7[/tex]
Therefore, the value of k is -7.
Draw the graphs of the equations y=8/3x and y=-8/3x on the same coordinate plane. Name their point of intersection as p. State the coordinate of the point p.
Answer:
Here we want to graph the equations:
f(x) = y =(8/3)*x
and
g(x) = y = -(8/3)*x
To graph these you need to find some coordinate points of each one, and then connect them, such that the graph of these two equations can be seen below.
Where the blue one is f(x) and the green one is g(x)
We now want to look at the graph and find the point of intersection p.
By looking at the graph below, we can see that the intersection is at the origin, then p = (0,0)
Also remember that an intersection of two functions means that:
f(x) = g(x)
for that particular x value, then we can solve this for our functions and get:
(8/3)*x = -(8/3)*x
That equation is only true when x = 0
Then we have the intersection at x = 0, and the correspondent y value is given by f(0) or g(0) (will be the same value)
y = f(0) = (8/3)*0 = 0 = -(8/3)*0 = g(0)
Then we also found analytically that the intersection is in the point (0, 0)
Different size containers. Tanner used for storing dry goods. The largest container held 12 /3/4 cups of dry goods. 2/3 of the amount in container a, 2/3 of the amount in container b. What was the total amount in cups of dry goods. That tanner could store in all three containers
Answer:
29 3/4 cups
Step-by-step explanation:
total amount of tanner in the 3 containers = sum of tanners in each container
total cups in containers b and c = 2/3 x 12 3/4
2/3 x 51/4 = 17/2 cups or 8 1/2 cups
total capacity = 8 1/2 + 8 1/2 + 12 3/4 = 17 + 12 3/4 = 29 3/4
Jasmine is planning a ski trip in the mountains with her friends. She can rent skis at the resort for $30 per day or she can buy skis to take with her for $150. Jasmine will also have to budget for a lift pass that costs $15 per day. How many days does she need to plan to ski in order for the cost of renting versus buying skis to cost the same for the trip?
Answer:
5 days.
Step-by-step explanation:
Jasmine has two options:
Rent skis at the resort for $30 per day.
Then if she rents the skis for N days, the cost will be:
C(N) = N*$30
Buy skis for $150
Now we can ignore the lift pass because she will pay that in both cases.
Now we want to find the number of days N such that the cost of renting is the same as the cost of buying.
Then we need to solve:
C(N) = $150
N*$30 = $150
N = $150/$30 = 5
So if you rent the skis for 5 days, you will pay the same as if you bought the skis.

Write the point-slope form of the equation of the line through the given point with the given slope.
through: (-5, -3), slope =4/9
Answer:
-3 - 1 = 4/9(-5 - 4)
Step-by-step Explanation:
Point-Slope form uses the formula y-y1=m(x-x1).
m is the slope, which they gave you, so you can substitute it into the formula:
y - y1 = 4/9(x - x1).
They also gave you a first point (-5, -3) So you can substitute the x and y of those into the formula as well.
-3 - y1 = 4/9(-5 - x1)
y1 and x1 are for another point. By drawing a graph and then using the rise and run of the slope (up 4 and over 9), you can get another point (as shown in the picture).
Substitute the x and y values of that point into the equation as well and you have your answer:
-3 - 1 = 4/9(-5 - 4)

Suppose we want to choose to letters without replacement three letters a b and c. How many ways can this be done if the order of the choices is relevant? How many ways can this be done if the order of the choices is not relevant?
Answer:
6 ;
3
Step-by-step explanation:
Letters = (a, b, c)
Number of letters to be chosen = 2
If the order is relevant, then we use permutation :
nPr = n! ÷ (n-r)!
3P2 = 3! ÷ (3-2)!
3P2 = (3 * 2 * 1) ÷ 1
3P2 = 6
If the order is not relevant ; We use combination :
nCr = n! ÷ (n-r)!r!
3C2 = 3! ÷ (3-2)!2!
3C2 = 3! ÷ 1!2!
3C2 = (3 * 2!) ÷ 2! * 1
3C2 = 3

A team of scientists is traveling by boat to study a pod, or group, of dolphins. The equation y = 0.2x can be used to find the distance, y, in miles the boat travels in x minutes. The dolphins are currently 8.4 mi from the boat. If the dolphins stay to where they are, how long will it take the boat to reach them? Show your work.
Answer:
42 minutes.
Step-by-step explanation:
We know that:
y = 0.2*x
is the equation that that defines the distance, in miles, that the boat travels in x minutes.
We know that the dolphins are at 8.4 miles from the boat.
Then when we have y = 8.4, this will mean that the boat reached the dolphins.
Then we need to solve the equation:
y = 8.4 = 0.2*x
for x
To do that, we just need to isolate x in one side of the equation, so we can just divide both sides by 0.2 to get:
8.4/0.2 = (0.2*x)/0.2
42 = x
And x is time in minutes, thus, the boat needs to travel for 42 minutes to reach the dolphins.

Si 1 kg de naranjas cuesta 14 pesos y al final del día el dueño de la frutería cuenta 1124 pesos por venta de naranjas, a) ¿cuántos kilogramos vendió? b) ¿cuánto cuesta comprar 3⁄4 de kg de naranjas? Si una señora compra dos naranjas cuyo peso fue de 0.3 kg, c) ¿cuánto pagó? Si en la compra de 5 kg de naranja se hace un descuento del 10%, d) ¿cuánto se paga? e) ¿Cuántos tipos de números hay en el problema?
Answer:
La respuesta a cada una de las preguntas es:
a) Se vendieron 562/7 kilogramos de naranjas.b) Comprar 3/4 de kg de naranjas cuesta 10.5 pesos.c) La señora pagó 4.2 pesos.d) Se paga 63 pesos por 5 kg de anaranja con el descuento.e) Se utilizan números racionales y números naturales.Step-by-step explanation:
a) Para calcular los kilogramos de naranjas vendidos durante el día, al tener el costo por kilogramo (14 pesos/kg) y la venta total (1124 pesos), puedes calcular de la siguiente forma:
Kilogramos vendidos = venta total / costo por kilogramoKilogramos vendidos = 1124 pesos / (14 pesos/kg)Kilogramos vendidos = 562/7 kg de naranjas.b) Para identificar el costo de 3/4 de naranja, debes multiplicar 3/4 por el valor del kg de naranja (14 pesos/kg):
Costo de 3/4 kg = (3/4 kg) * (14 pesos/kg)Costo de 3/4 kg = 10.5 pesos.c) Si la señora compra un peso total de 0.3 kg de naranja, para obtener el costo debes realizar la misma operación del ejercicio anterior, es decir, multiplicar los kilos comprados (0.3 kg) por el costo de cada kilogramo de naranja (14 pesos/kg):
Costo de 0.3 kg = 0.3 kg * (14 pesos/kg)Costo de 0.3 kg = 4.2 pesosd) Para calcular el costo de 5 kg de naranja con un descuento del 10%, debemos multiplicar el costo por kilogramo (14 pesos/kg), por el número de kilogramos comprados (5 kg), y luego por el porcentaje restante tras el descuento (90%), puesto que el total es el 100% y le restamos el 10% de descuento, nos queda el 90%:
Precio total de 5 kg de naranja tras descuento = (14 pesos/kg * 5 kg) *90%Precio total de 5 kg de naranja tras descuento = 70 pesos * 90%Precio total de 5 kg de naranja tras descuento = 63 pesos.e) De entre todos los tipos de números que hay, dentro de los ejercicios resueltos se hace uso de los números racionales (por el uso de fraccionarios) y de los números naturales (por el uso de los números enteros positivos).
