Honda Atlas issued 100,000 shares of stock. In 1990, each share of stock was worth Rs. 152.50. In 1993, each share of the stock
noname [10]

Answer:

Rs.13,130 ,000

Step-by-step explanation:

Lets solve first for year 1990

Value of stock in 1990 = Rs. 152.50

No. of stocks issued in 1990 = 100,000

Total value of these stocks in 1990= Value of stock in 1990* no of stocks issued in 1990  = 152.50*100,000 = Rs. 15,250,000

Let solve first for year 1993

Value of stock in 1993 = Rs. 21.20

No. of stocks   1993 = 100,000

Total value of these stocks in 1993 = Value of stock in 1993* no of stocks issued in 1993  = 21.20*100,000 = Rs. 2,120,000

Decrease in value of stock in 1993 in comparison to 1990 = Total value of the stocks in 1990 -Total value of the stocks in 1993

 =  Rs. 15,250,000 - Rs. 2,120,000

 = Rs.13,130 ,000

Thus, the 100,000 shares worth Rs.13,130 ,000 lesser in 1993 than in 1990.

PLEASE HELP FASTTT!!!
nirvana33 [79]

Answer:

5 seconds

Step-by-step explanation:

Looking at your function (h(t) = -16t^2 + 48t + 160), I see that the peak height will be 196 feet, and that is achieved in 1.5 seconds.

h(1.5) = -16(1.5)^2 + 48(1.5) + 160

h(1.5) = -16(2.25)+ 48(1.5) + 160

h(1.5) = -36 + 48(1.5) + 160

h(1.5) = -36 + 72 + 160

h(1.5) = 36 + 160

h(1.5) = 196

Going down from that height, it would take 3.5 more seconds, so it would take 5 seconds in total

h(5) = -16(5)^2 + 48(5) + 160

h(5) = -16(25) + 48(5) + 160

h(5) = -400 + 48(5) + 160

h(5) = -400 + 240 + 160

h(5) = -400 + 400

h(5) = 0

-9 a que conjunto pertenece -4/4 a que conjunto pertenece -5.124 a que conjunto pertenece rapidoo pls
Hunter-Best [27]

Answer:

-9 al conjunto de los números enteros.

-4/4 pertenece a los enteros.

-5.124 pertenece al conjunto de los racionales

Step-by-step explanation:

En esta pregunta, básicamente lo que debes hacer es clasificar cada uno de los números de acuerdo al conjunto numérico. Como podrás ver en la foto 1, tienes una representación gráfica de los conjuntos numéricos existentes.

Los números naturales (N), comprenden desde el 1 hasta el infinito.

Los números enteros (Z) comprenden los negativos, el cero y todos los naturales.

Finalmente los números racionales (Q) comprenden los números enteros, los naturales y también fracciones y números decimales.

De acuerdo a estas definiciones y la foto, podemos observar que todos los números dados acá pertenecen al conjunto general de los racionales (Q), pero veamos ahora específicamente a cual:

El número -9 (o el 9) si es negativo, pertenece a los enteros; si es positivo sería entero y natural.

El número -4/4 es una fracción, que al ser dividida da como resultado el número -1, y este pertenece a los enteros.

El número -5.124 (o 5.124) es un número decimal finito, por lo que proviene de una fracción, asi que pertenece a los números racionales.

Espero que esto te ayude.
