Answer:
Thats the answer from american school
Step-by-step explanation:
The value of the common length BD would be 8 units aprroximately.
What are trigonometric identities?Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.
Given information;
1. Considering line BD as a side of ABD, express its length in terms of variables representing side lengths and angle measures in ABD.
So, We know that
Sin A = BD / AB
Sin A = BD / c
c Sin A = BD
Substitute;
(10) Sin (53.13) = BD
BD = 10 ( 0.79)
BD = 7.99
Therefore, the value of the common length BD would be 8 units aprroximately.

A restaurant critic reviewed restaurants in Oxford and Fairview.
In Oxford, the critic gave 18 negative reviews and 33 positive reviews.
ratio = 18 / 33 = 0.54
In Fairview, 5 of the reviews were negative and 11 were positive reviews.
Ratio = 5 / 11 = 0.45
Thus, the required, the city of Fairview has a lower ratio of negative to positive reviews.

7x+1/2(x+1/4)=3(6x-9)-8
Answers
Answer:
x = 381/24 = 3 29/84
Step-by-step explanation:
7x + 1/2(x + 1/4) = 3(6x - 9) - 8
Use the distributive property to multiply 1/2 by x + 1/4.
7x + 1/2x + 1/8 = 3(6x - 9) - 8
Combine 7x (14/2x) and 1/2x to get 15/2.
15/2x + 1/8 = 3(6x - 9) - 8
Use the distributive property to multiply 3 by 6x - 9.
15/2x + 1/8 = 18x - 27 - 8
Subtract 8 from -27 to get -35.
15/2x + 1/8 = 18x - 35
Subtract 18x from both sides.
-21/2x + 1/8 = -35
Subtract 1/8 from both sides.
-21/2x = -35 - 1/8
-35 is the same as -280/8.
-21/2x = (-280 - 1)/8
Subtract 1 from -280 to get -281.
-21/2x = -281/8
Multiply both sides by -2/21 (reciprocal of -21/2).
x = (-281 * -2)/(8 * 21)
You can cross cancel -2 and 8 by extracting 2 (they become -1 and 4 respectively).
x = (-281 * -1)/(4 * 21)
Multiply -281 by -1 to get 281.
x = 281/(4 * 21)
Multiply 4 by 21 to get 84.
x = 281/84
Can this fraction be simplified into a mixed number? Yes it can. It becomes 3 29/84. (252 (3 * 84) + 29 = 281)
x = 3 29/84
Work check: x is substituted for 281/84 (convenience)
7 * 281/84 + 1/2(281/84 + 1/4) = 3((6 * 281)/84 - 9) - 8
1967/84 + 1/2(281/84 + 1/4) = 3((6 * 281)/84 - 9) - 8
1967/84 + 1/2(302/84) = 3((6 * 281)/84 - 9) - 8
(1967 + 151)/84 = 3((6 * 281)/84 - 9) - 8
2118/84 = 3(1686/84 - 9) - 8
2118/84 = 3((1686 - 756)/84) - 8
2118/84 = 3(930/84) - 8
2118/84 = 2790/84 - 672/84
2118/84 = (2790 - 672)/84
2118/84 = 2118/84
So x = 3 29/84 is correct.

Answer:
an = 6n - 18
Step-by-step explanation:
a3 = 0, a4 = 6, a5 = 12, a6 = 18, a7 = 24
a3 = a + 2d
a4 = a + 3d
a + 2d = 0 (1)
a + 3d = 6 (2)
Subtract (1) from (2) to eliminate a
3d - 2d = 6 - 0
d = 6
Substitute d = 6 into (1)
a + 2d = 0 (1)
a + 2(6) = 0
a + 12 = 0
a = -12
nth term,an = a + (n - 1)d
= -12 + (n - 1) 6
= -12 + 6n - 6
= 6n - 18
an = 6n - 18

Cuatro amigos van al cine dos veces al mes y siempre comen un paquete de palomitas de maiz cada uno si no comia palomitas de maiz los cuatro amigos podrian ir al cine tres veces al mes sabiendo que cada paquete de palomitas de maiz cuesta $28 cual es el precio de cada entrada al cine
Answers
Answer:
El precio de la entrada al cine es de $56
Step-by-step explanation:
Cada uno de los 4 amigos las 2 veces por semana consumen un paquete de palomitas que cuesta: $28 ; entonces debemos multiplicar el costo de las palomitas por las dos veces que las consumen para saber el costo total de las palomitas:
28 x 2 =$56
El ejercicio nos dice que al no comer esas dos veces palomitas pueden ingresar a cine una tercera vez por semana ,lo que significa que al no pagar los $56 en palomitas podrán pagar una tercera entrada,lo que quiere decir que la entrada a cine es de $56.
Entonces podemos hacer la siguiente relación matemática: Precio total de las palomitas dos veces por semana = Precio de la entrada a cine.
