Respuesta: 50N

Explicación paso a paso:

Dado lo siguiente:.

Tensión (T) = 52,9 N

Masa (m) = 10,5 kg

La normal se obtiene usando la relación:

N = mg - T; donde N = normal, g = aceleración debida a la gravedad (9,8 m / s²)

N = mg - T

N = (10,5 * 9,8) - 52,9

N = 102,9 - 52,9

N = 50 N

Answer:

5,000,000= 625000 this many tickets if there 8 $

Step-by-step explanation:

And the ticket is  8$

How you would solve it is you take the number of money and divide it by how much each of the tickets are then the finished product is how many you have to sell.

Answer:

$6 Each

Step-by-step explanation:

First, add all the costs together:

3 $6 apps

   3*6=18

2 $3 desserts:

   2*3=6

Add the totals up to get a total of $24, then divide that by 4 since it's being split between 4 people.

Answer:

The rate of change or the slope is 7. (If you were to graph this, you would use 7/1.

Step-by-step explanation:

To find the slope when you're given two sets of points, you must find the distance from the y values and the distance from the x values!

Y values: distance from -2 to 5 is +7

X values: distance from -2 to -1 is +1

7/1 or just 7.

Answer:

Side = [tex]5\sqrt5\ \text{feet}[/tex]

Step-by-step explanation:

Given that,

Area of a square room is 125 square feet

We need to find the length of one side of the room.

The area of a square shaped room is given by :

[tex]A=x^2[/tex]

Where, x is side of the square room

[tex]x=\sqrt{A} \\\\x=\sqrt{125}\\\\x=\sqrt{5\times 5\times 5}\\\\x=5\sqrt5\ \text{feet}[/tex]

So, the side of the room is [tex]5\sqrt5\ \text{feet}[/tex].

Answer:

It seems that the slope of this line is 1/5, yet none of the answers correspond to this. Double-check by finding two points on the line, and use the slope formula: (y2-y1/x2-x1). Also, remember that slope is rise/over run. I hope this can guide you!

Answer: the answer is not included in the options

Step-by-step explanation:

The slope of the line can be depicted by the following formulas: 1. Rise/run 2. Y1-y2/ x1-x2

If we were to use the second formula and “plug” in numbers for the variables, the slope we calculate is less than 1

Answer:

x = -6

Step-by-step explanation:

Simplifying

5x + 7 = 3x + -5

Reorder the terms:

7 + 5x = 3x + -5

Reorder the terms:

7 + 5x = -5 + 3x

Solving

7 + 5x = -5 + 3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3x' to each side of the equation.

7 + 5x + -3x = -5 + 3x + -3x

Combine like terms: 5x + -3x = 2x

7 + 2x = -5 + 3x + -3x

Combine like terms: 3x + -3x = 0

7 + 2x = -5 + 0

7 + 2x = -5

Add '-7' to each side of the equation.

7 + -7 + 2x = -5 + -7

Combine like terms: 7 + -7 = 0

0 + 2x = -5 + -7

2x = -5 + -7

Combine like terms: -5 + -7 = -12

2x = -12

Divide each side by '2'.

x = -6

Simplifying

x = -6

The solution to the equation 5x + 7 = 3x - 5 is x = -6.

We have,

To solve the equation 5x + 7 = 3x - 5, we need to isolate the variable x on one side of the equation.

Here's how we can do that:

Start by subtracting 3x from both sides of the equation to move all the x terms to one side:

5x + 7 - 3x = 3x - 5 - 3x

Simplifying, we get:

2x + 7 = -5

Next, subtract 7 from both sides of the equation to isolate the term with x:

2x + 7 - 7 = -5 - 7

Simplifying, we get:

2x = -12

Now, to solve for x, we divide both sides of the equation by 2:

(2x)/2 = (-12)/2

Simplifying, we get:

x = -6

Thus,

The solution to the equation 5x + 7 = 3x - 5 is x = -6.

Step-by-step explanation:

Answer:

[tex]m=20c[/tex]

Step-by-step explanation:

Let m represent the total money collected and c represent the amount of cars washed.

We know that the money collected is directly proportional to the number of cars washed. So, we can write the following equation:

[tex]m=kc[/tex]

Where k is a constant.

We know that the money collected after 7 car washes is $140. So, let's find our k by substituting 140 for m and 7 for c. This yields:

[tex]140=7k[/tex]

Find k. Divide both sides by 7:

[tex]k=20[/tex]

So, the value of k is 20.

We can now substitute k back into our direct variation equation:

[tex]m=20c[/tex]

This means that every car costs $20 to wash.

And we're done!

Answer:

7x140=980

Step-by-step explanation: 50x0.8=40

Okay, maybe im wrong? But i dont see how its 4 thats more than half.

Rodger can do 46 pushups.

50 * 0.92 = 46

Edit: To better clarify, 0.92 is from 1.00 - 0.08.  

... 8 percent fewer than 100 percent is 92 percent; 1.00 - 0.08 = 0.92

Keep in mind that:

1.00 = 100%

0.08 = 8%

0.92 = 92%

After finding this you may multiply 50 * 0.92 to get 46.
