Find the value of X please help

11. The formula for finding a number that's the square root of the sum of another number n and 6 is

Dafna1 [17]

Answer:

x = $\sqrt{x+6}$

Step-by-step explanation:

The question states that it is the square root of the sum of both n and 6. That means n and 6 are added first before square rooted. Between B and C, choose the answer that has the parenthesis around x and 6, like (x + 6).

The scale on a model railroad train set is 3.5 millimeters to 1 foot. If the length of a model car in the set is 150 millimeters

Vera_Pavlovna [14]

Answer:

The approximate length of the actual car is 43 feet.

Step-by-step explanation:

Given:

The scale on a model railroad train set is 3.5 millimeters to 1 foot. If the length of a model car in the set is 150 millimeters.

Now, to find the approximate length of the actual car.

Let the actual length of the car is $x.$

The length of a model car in the set is 150 millimeters.

As, given the scale on a model railroad train set is 3.5 millimeters to 1 foot.

So, 3.5 millimeters equivalent to 1 foot.

Thus, 150 millimeters to $x$ .

Now, to get the actual length of the car by using cross multiplication method:

$\frac{3.5}{1} =\frac{150}{x}$

By using cross multiplying we get:

$3.5x=150$

Dividing both sides by 3.5 we get:

$x=42.85\ feet.$

The approximate length of the actual car = 43 feet.

Therefore, the approximate length of the actual car is 43 feet.

D is the centroid of triangle abc. what is the value of x when bd=2x+40 and bf=18x

Luda [366]

The value of x= 20 units

BD = BF

BD =2x + 40

BF = 18x

Equate the expressions thus:

2x + 40 = 2/3(18x)

2x + 40 = 12x

Collect like terms

2x - 12x = - 40

-2x = - 40

Divide both sides by - 2

x = 20

Hence, x = 20 units

The centroid is the center point of the item. The factor in which the 3 medians of the triangle intersect is known as the centroid of a triangle. it is also defined because of the point of intersection of all the 3 medians. The median is a line that joins the midpoint of a facet and the opposite vertex of the triangle.

Then, we can calculate the centroid of the triangle by means of taking the common of the x coordinates and the y coordinates of all of the three vertices. So, the centroid method can be mathematically expressed as G(x, y) = ((x1 + x2 + x3)/3, (y1 + y2 + y3)/three).

The centroid of a triangle is the point at which the 3 medians coincide. The centroid theorem states that the centroid is 23 of the space from each vertex to the midpoint of the opposite aspect.
