ting bikes for x hours.
Mathematics
1 answer:
Katen [24]3 years ago
6 0

Answer:

<em></em>y = 12 + 6x<em></em>

<em></em>

Step-by-step explanation:

Given

Base\ Amount = 12

Additional = 6 per hour

Required

Determine the expression for the cost in x hours

Represent the cost with y

y is calculated using the following expression

y = Base\ Amount + Additional * x

Where x represent the number of hours.

Substitute values for the base amount of bike and the additional cost per hour

y = 12 + 6 * x

y = 12 + 6x

<em>So, the expression to determine the cost of bike in x hours is: </em>y = 12 + 6x<em></em>

The sun is about 93 x 10^6 miles from earth. what is this distance written as a whole number? 
agasfer [191]

For this case we have the number in exponential notation:

93 * 10 ^ 6

We observe that the exponent of the exponential notation is positive.

Therefore, to express the number as a whole number, we must move the comma 6 spaces to the right.

We have then:

93 * 10 ^ 6 = 93,000,000

Answer:

this distance written as a whole number is:

93 * 10 ^ 6 = 93,000,000 miles

9. Calcule el valor de la fuerza que experimenta un ascensor cuando levanta 150 kg en los siguientes casos: a) Cuando asciende c
GenaCL600 [577]

Answer:

a) La fuerza neta que experimenta un ascensor cuando asciende con una aceleración de 4 metros por segundo al cuadrado es 600 newtons hacia arriba.

b) La fuerza neta que experimenta un ascensor cuando desciende con una aceleración de 6 metros por segundo al cuadrado es 900 newtons hacia abajo.

c) Por la fuerza de tensión sobre el cable del ascensor.

Step-by-step explanation:

a) La fuerza neta experimentada por el ascensor (F), en newtons, es:

F = m\cdot a (1)

Donde:

m - Masa, en kilogramos.

a - Aceleración, en metros por segundo cuadrado.

Si sabemos que m = 150\,kg y a = 4\,\frac{m}{s^{2}}, entonces la fuerza neta del ascensor es:

F = m\cdot a

F = 600\,N

La fuerza neta que experimenta un ascensor cuando asciende con una aceleración de 4 metros por segundo al cuadrado es 600 newtons hacia arriba.

b) Si sabemos que m = 150\,kg y a = -6\,\frac{m}{s^{2}}, entonces la fuerza neta del ascensor es:

F = m\cdot a

F = -900\,N

La fuerza neta que experimenta un ascensor cuando desciende con una aceleración de 6 metros por segundo al cuadrado es 900 newtons hacia abajo.

c) De manera simplificada, el ascensor experimenta dos fuerzas que definen la fuerza y aceleración netas: (i) La fuerza de tensión sobre el cable que traslada el ascensor y el peso total del ascensor, opuesta a la anterior y en función de la aceleración gravitacional. Puesto que la masa no varía en ningún caso, se concluye que el peso es constante, entonces la diferencia de valores se debe a la fuerza por tensión del cable. En el descenso, es fuerza es menor que en el ascenso.

(10.5-7)+(4x3) help please
Leno4ka [110]

Answer: 15.5

Step-by-step explanation:

(10.5-7)+(4x3)

following PEDAS we do operations in parentheses first

10.5-7=3.5

4x3=12

we now have 3.5+12 as our intermediate expression

and 3.5+12 = 15.5
