Noah is running a portion of a marathon at a constant speed of 6 miles per hour.

If Noah is running 6 miles an hour then we know that for every hour, he is running 6 miles. You have to multiply each hour he’s running by 6.

For the last three answers, since they give you how much time he ran, you have to divide by 6 miles.

Answers:
1 = 6
1/2 = 3
1 1/3 = 8
(I can’t see the fourth one)
1 1/2 = 9
3/4 = 4 1/2

I can only see the numbers for the top half of the table. If you tell me what the bottom half of the table, I will do it.

Time in Hours miles traveled
6 hours 6 miles
1/2 hours 3 miles
1 1/3 8 miles

15/3x =5

x= 5

5+2y= 315

5-5+2y =315-5

2y = 310

2y/2 = 310/2

y=155

Step-by-step explanation:

2x+4y=450

2×5=10

10+(4×155)

=620/155

=4

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.

Which number(s) below belong to the solution set of the inequality? Check all that apply.x + 16 < 51.
natta225 [31]
If you subtract 16 on both sides... x will be alone. Therefore 51-16=35
x=35 (B)

HEY THERE!!

AS we know COSINE =PERPENDICULAR /BASE

SO ACCORDING TO ABOVE IMAGE
PERPENDICULAR is 5 ft
AND BASE
is 8 ft

so now cosine A = 5/ 8

MEAN THE CIRRECT ANSWER IS (D)

For what value of x would the expression below be undefined? 2x − 15 x + 9
Naddik [55]
Hey there!

I'm assuming your expression is actually \frac{2x - 15}{x + 9}. If it's not, let me know and I'll be happy to help you out further. 

If x were equal to –9, your expression would be undefined. If you solve it with this value plugged in for x, you will get the following: 

\frac{2x - 15}{x + 9}

\frac{2(-9) - 15}{(-9) + 9}

\frac{-18 - 15}{0}

\frac{-33}{0}

error

You can't divide anything by zero. This expression would be undefined if x were –9 since it makes the denominator zero. Therefore, x ≠ –9. 

Hope this helped you out! :-)
