Answer:

Step-by-step explanation:

18=2(3)3

36=2(2)3(3)

The GCF will be the product of their common factors, specifically 2(3)3=18

Tomando el cociente entre la masa de la muestra y la masa de un átomo, veremos que hay 1.7*10^21 átomos de uranio en la muestra.

Para determinar el número de átomos en la muestra, simplemente debemos dividir la masa de la muestra (0.7 gramos) por la masa de un átomo de uranio (4*10^(-25) kg)

Donde la complicación viene por que tenemos distintas unidades.

Para resolver esto, podemos escribir la masa de la muestra en kilogramos.

Sabemos que: 1g = 1*10^-3 kg

Entonces podemos reescribir la masa de la muestra como:

0.7g = (0.7)*(10^-3 kg) = 7*10^-4 kg

Ahora si podemos tomar el cociente, el número de átomos esta dado por:

[tex]N = \frac{7*10^{-4}kg}{4*10^{-25}kg} = 1.7*10^{21}[/tex]

Así podemos concluir que hay 1.7*10^21 átomos de uranio en la muestra.

Answer:

45

Step-by-step explanation:

each bracelet takes 15 min

15*3=45

1 hour = 60 minutes..

In 1 hour she makes 4

In 2 hours (120 minutes) she makes 8

So in each hour she makes 4 ( 8 /2 = 4)

So In 3 hours she will make 3 x 4 = 12 bracelets

Answer:

r=1, h=9

r=2, h=2.25

r=5, h=0.36

r=12, h=0.0625

r=r, h=9/r²

Step-by-step explanation:

Volume of a cone = πr²h/3

3π=πr²h/3

r²h=9

when r=1?

r²h=9

1²h=9

h=9

when r=2?

r²h=9

2²h=9

4h=9

h=2.25

when r=5?

r²h=9

5²h=9

25h=9

h=0.36

when r=12?

r²h=9

12²h=9

144h=9

h=0.0625

when r=r?

r²h=9

h=9/r²

The height of a cone is dependent on its radius. The height for a cone radius of 1 is 9.

Volume is the amount of space that is occupied by a three dimensional object.

The volume of a cone (V) is given by:

V = (1/3)πr²h

Where r is the radius and h is the height.

For a radius of 1:

3π = (1/3)π*(1)² * h

h = 9

For a radius of 2:

3π = (1/3)π*(2)² * h

h = 2.25

For a radius of 5:

3π = (1/3)π*(5)² * h

h = 0.36

For a radius of 12:

3π = (1/3)π*(12)² * h

h = 0.02

The height of a cone is dependent on its radius. The height for a cone radius of 1 is 9.

Answer:

900 miles long

Step-by-step explanation:

Given data

Le the total mile of the trip be x

Autumn fell asleep at 39% of the trip, which is equal to 351 miles

so

=39/100*x= 351

0.39x= 351

divide both sides by 0.39

x= 351/0.39

x= 900 miles

Hence the trip is 900 miles long

Answer:

B. (3x - 12)° = (2x + 8)°

Step-by-step explanation:

This equation can be used to solve x.

3x - 12 = 2x + 8

3x - 2x = 12 + 8

x = 20°

-------------------------------------------------------------------

Verification:

3(20) - 12 = 2(20) + 8

60 - 12 = 40 + 8
