Answer:

2/3 Rupees

Step-by-step explanation:

Lets say Chocolate is C and a rupee is R.

Then, 15C = 10R. We can simplify to 3C = 2R. Now we divide both sides by Three to get C = 2/3R, which means a chocolate is 2/3 of a rupee!

Check that 2b+b and 3b have the same value when b is 1,2, and 3. Do 2b+b and 3b have the same value for all values of b? Explain

Inessa [10]

Answer:

Expression 2b+b and 3b have same values for all values of b.

Step-by-step explanation:

Given the two expression $2b+b$ and $3b$ and values of b as 1, 2 and 3.

Consider first expression that is, $2b+b$ .

Substituting the value of $b=1$ ,

$2\left(1\right)+\left(1\right)=2+1=3$ ....1

Substituting the value of $b=2$ ,

$2\left(2\right)+\left(2\right)=4+2=6$ ....2

Substituting the value of $b=3$ ,

$2\left(3\right)+\left(3\right)=6+3=9$ ....3

Consider second expression that is, $3b$ .

Substituting the value of $b=1$ ,

$3\left(1\right)=3$ ....4

Substituting the value of $b=2$ ,

$3\left(2\right)=6$ ....5

Substituting the value of $b=3$ ,

$3\left(3\right)=9$ ....6

For value of b=1, equation 1 and equation 4 are same, for value of b=2, equation 2 and equation 5 are same and for value of b=3 equation 3 and equation 6 are same.

Therefore both expression are same for all values of b.

¿Qué altura tiene un poste que proyecta una sombra de 21 metros, al mismo tiempo que una persona de 1.75 metros de estatura lo o

prisoha [69]

Respuesta:

27,22 metros

Explicación paso a paso:

Dado :

Sombra del poste = 21 metros

Altura de la persona = 1,75 metros

Sombra de la persona = 1,35 metros

Altura del poste =?

Usando la relación:

Altura de la persona / sombra de la persona = altura del poste / sombra del poste

1,75 / 1,35 = x / 21

Cruz multiplicar

1,35 * x = 1,75 * 21

x = (1,75 * 21) / 1,35

x = 27,22

Here is the function for the number of zombies, N, after t years, with the negative exponent expressed using the fraction ½: N(t

Xelga [282]

The correct answer should be: Eight years. To get ½ of the 300, you need 0.5^(t/8) to equal ½, or 0.5. That means that the exponent must be 1. This happens when t = 8 years.
