Explicación paso a paso:
Workdone = Fuerza * distancia movida en la dirección de la fuerza
Dado
Fuerza f = 40N
Distancia = 6 m
El trabajo realizado por la fuerza F es:
Trabajo hecho = 40 * 6
Trabajo terminado = 240 Nm
El trabajo realizado por la fuerza de la gravedad es el trabajo realizado por el cuerpo de 2 kg:
W = mg
W = 2 * 10
W = 20N
Trabajo realizado = 20 * 6
Trabajo terminado = 120 Nm
En un cuartel, los 2/3 de las personas que hay son soldados y el resto son oficiales, suboficiales y jefes. El número de jefes es 1/12 del resto y el número de oficiales es cuatro veces mayor que el número de jefes. Halla el número de oficiales, suboficiales y jefes, sabiendo que hay 600 soldados. *
Answer:
25 jefes
100 oficiales
175 suboficiales
Step-by-step explanation:
Se nos dice que hay 600 soldados que está representado por una fracción de 600
Podemos obtener el número total de personas en el cuartel.
Representemos el número total de personas en el cuartel como: B
2/3 × B = 600
2B / 3 = 600
Cruz multiplicar
2B = 600 × 3
B = 1800/2
B = 900
Por lo tanto, el número total de personas en el Cuartel es de 900 personas.
De la pregunta se nos dice que:
el resto son oficiales, suboficiales y jefes.
Calcule el número total de personas en el cuartel con 1
El resto se representa como:
1 - 2/3 = 1/3
El número de jefes es 1/12 del resto
Por lo tanto,
= 1/12 de 1/3
= 1/12 × 1/3
= 1/36
El número total de personas = 900
Por tanto, el número de jefes = 1/36 × 900
= 25 jefes
Tenemos 25 jefes
El número de oficiales es cuatro veces mayor que el número de jefes.
= Número de oficiales = 4 (1/36)
= 4/36
= 1/9
El número total de personas = 900
Por lo tanto, el número de oficiales = 1/9 × 900
= 100 oficiales
Tenemos 100 oficiales
El número de suboficiales se calcula como:
900 - (600 + 25 + 100)
= 900 - 725
= 175

Find the sum of the interior angle measures of a convex 20-gon (a twenty-sided polygon).
Answer:
3,240°
Step-by-step explanation:
Sum of interior angles of n-sided polygon is given as (n - 2)180. Where n = number of sides of the polygon.
Sum of angles of a convex 20-gon = (20 - 2)180
= (18)180 = 3,240°
Sum of interior angles of a convex 20-gon = 3,240°
Answer:
3,240
Step-by-step explanation:
(n-2)180 n is the number of sides
Substitute 20 for n, then simplify
(20 - 2)180 = (18)180 = 3,240
Martina purchased a prepaid phone card for $15 . Long distance calls cost 8 cents a minute using this card. Martina used her card only once to make a long distance call. If the remaining credit on her card is $11.48 , how many minutes did her call last?
Answer:
44 minutes
Step-by-step explanation:
With regards to the above information, we can calculate the minutes in which Martina's call lasted as shown below;
We can make y represent the minutes
15 - 8y/100 = 11.48
15 - 0.08y = 11.48
15 - 11.48 = 0.08y
0.08y = 3.52
y = 3.52/0.08
y = 44
It therefore means that Martina's call lasted for 44 minutes.

Answer:
z =6
Step-by-step explanation:
so we simplify from both side.
2( 2z - 3) = 18
*2 *2
4z - 6 = 18
+ 6 +6
4z = 24
then we divide both sides from 4

Alden measured the water level in his pool each day. Ever day, the water level went down 1 1/2 inches he measured the pool for 5 straight days. Which value in this situation could be represented by a negative number?
Answer:
Decrease or decline in water level per day
Step-by-step explanation:
Given the question above ;
The situation which could be repress Ted by a negative number is the decrease in the water level of the pool being measured :
It could be expressed as - 1 1/2 inches per day
Fall, decrease, loss or reductions are usually modeled in mathematics using the negative sign as it portrays a negative adjustment or reduction in the original amount of a commodity, item or phenomenon.
Furthermore, total decline after 5 days will be ;
-1 1/2 * 5 = (-3/2 * 5) = - 15/2 = - 7.5 inches

minutes in the competition tonight, how many mistakes will she
make?
A. 12
B. 15
C. 16
D. 27
E. 30
Answer:
(A) 12
Step-by-step explanation:
This is actually very simple!
If Talia makes 2 mistakes every 3 minutes then the ratio is 2:3
Going along with that if you know how ratios work then that should be easy. But this is also the long way. You dont really need to know ratios you just need to know the steps but knowing ratios would be helpful.
You first divide
18 / 3 = 6
Then multiply
6 x 2 = 12
That's it!

Answer:
- 12x + 24
Step-by-step explanation:
Since the perimeter is 2(length) + 2(width) your equation would start out as:
2[-2(3x-1)] + 2(10x)
2[-2(3x-1)] + 20 = 2(-6x + 2) + 20
2(-6x + 2) + 20 = - 12x + 24

21) 64=8(r+2)
Step 1: Simplify both sides of the equation.
64=8(r+2)
64=(8)(r)+(8)(2)(Distribute)
64=8r+16
Step 2: Flip the equation.
8r+16=64
Step 3: Subtract 16 from both sides.
8r+16−16=64−16
8r=48
Step 4: Divide both sides by 8.
8r
8
=
48
8
r=6
29) Step 1: Simplify both sides of the equation.
−4(r+6)=−63
(−4)(r)+(−4)(6)=−63(Distribute)
−4r+−24=−63
−4r−24=−63
Step 2: Add 24 to both sides.
−4r−24+24=−63+24
−4r=−39
Step 3: Divide both sides by -4.
and you get r= 39\4
hope that helps
Answer: r = 6
Step-by-step explanation:
64= 8(r+2)
64/8 = 8(r+2) / 8 divide both sides by 8
8 = r + 2 The eights cancel out
- r = 2 + 8 Move the variable to the left and change its sign
- r = - 6 to get id of the negative -r make the 6 a positive
r=6
-4(r + 6) = -63
- 4r - 24 = -63 Distribute 4 through ( ) -4 x4 -4 x6
-4r =63 + 24 Move -24 to the right (making it a positive )
-4r = 39
-4r / -4 = 39 /4 divide both sides by -4
r= 39/4
I’m having trouble solving this problem, please help!
Help me quickly please
Answer:
Yes
Step-by-step explanation:
To determine whether a relation is a function or not, we can do a vertical line test. First, get something like a ruler, put it vertical, then scan it on the relation. If the ruler hits one point of the line, then it is a function. If the ruler hits two points at once, then it is not a function. This passes the vertical line test, because when the ruler hits the relation it only hits one point at a time, making it a function. I hope this helps, I hope it's not wrong but I don't think it is.
