Answer 1

Answer:

[tex]B = 50.5^\circ[/tex]

Step-by-step explanation:

Given

[tex]AB = 11[/tex]

[tex]BC = 7[/tex]

See attachment

Required

Determine [tex]\angle ABC[/tex]

[tex]\angle ABC[/tex] implies that we calculate the angle at B.

Given that:

[tex]AB = 11[/tex] --- Hypotenuse

[tex]BC = 7[/tex] --- Adjacent of B

We apply cosine formula

[tex]\cos(B) = \frac{Adjacent}{Hypotenuse}[/tex]

[tex]\cos(B) = \frac{BC}{AB}[/tex]

[tex]\cos(B) = \frac{7}{11}[/tex]

[tex]\cos(B) = 0.6364[/tex]

Take arccos of both sides

[tex]B = cos^{-1}(0.6364)[/tex]

[tex]B = 50.5^\circ[/tex]

What is diameter:

in geometry, a diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle. Both definitions are also valid for the diameter of a sphere.

What is radius:

In classical geometry, a radius of a circle or sphere is any of the line segments from its center to its perimeter, and in more modern usage, it is also their length. The name comes from the Latin radius, meaning ray but also the spoke of a chariot wheel.

Explanation:

The diameter is the line that goes across the center of the circle and double the radius which is half, therefore KR is the correct answer.

Answer:

KR, D, or the last option.

Statement answer:

Segment KR is the Diameter of Q.

En una tienda en la que todo está rebajado el 15% he comprado un pantalón por el que he pagado 102 €. ¿Cuál era el precio antes de la rebaja?

Answers

Answer:

120 euros

Step-by-step explanation:

X= 100% del precio (antes de la rebaja)

Pagaste el 85% pues habia descuento del 15%

85%--------------102

100%---------------x

CROSS MULTIPLICATION

85X  =  10200

Divide cada parte por 85

x= 120

Teniendo en cuenta la definición de descuento, el precio antes de la rebaja era 120 €.

En una operación de descuento, el valor que se paga después de haberle practicado el descuento se denomina “valor actual”.  

Recordando que el porcentaje representa una parte del total, el valor actual se puede calcular multiplicando el porcentaje a descontar por el precio original,  al cual luego se divide por cien. Finalmente, se resta al precio original este valor de descuento calculado. De esta manera se averigua el precio de venta.

Entonces, sea el precio original del producto p. Por lo que el descuento del precio original será:

15% de p= (15×p) ÷10

Sabiendo que se ha pagado 102 € por el pantalón, entonces:

p - (15×p) ÷10 = 102

Resolviendo

p - 0,15×p= 102

0,85×p= 102

p= 102÷0.85

p= 120

Finalmente, el precio antes de la rebaja era 120 €.

Events A and B are mutually exclusive. Suppose event A occurs with probability 0.36 and event B occurs with probability 0.31. Compute the following. (If necessary, consult a list of formulas.) (a) Compute the probability that A does not occur or B does not occur (or both). 0. x 5 ? (b) Compute the probability that either A occurs without B occurring or A and B both occur. 0.36​

Answers

Answer:

Events A and B are dependent

Step-by-step explanation:

If A and B are two events such as A and B are dependent then

P(A∩B)  P(A) P(B)

An event A will occur with probability 0.4 that is  

An event B will occur with probability 0.6 that is  

The probability that both A and B will occur is 0.20 that is P(A∩B) = 0.20

Therefore,

P(A∩B)  P(A) P(B)

Adam jogs at an average speed of 10km/h from his house to the airport. The airport is 7km away from his house. At what time must Adam leave his house in order for him to reach the airport at 7:20 am.

Answers

Answer:

6:38am

Step-by-step explanation:

From the question we are told that

Average speed [tex]V_{avg}=10km/h[/tex]

Distance traveled [tex]d=7km[/tex]

Generally the velocity across a distance is mathematically given given as [tex]V=d/t[/tex]

[tex]10=\frac{7}{t}[/tex]

[tex]t=0.7h\\t=42minutes[/tex]

Therefore

7:20-42 minutes =6:38am
