Given the following square, solve for x.
(7x+13) °

Answer: 0

Step-by-step explanation:

1/2x = -1/2x cannot be true for any other value of x except when x equals 0. In other words, we need the left and right sides to equal each other, but that would only happen when x=0.

Step-by-step explanation:

To find the probability of the sum of two randomly selected numbers from a set being greater than 12, we need to first find the total number of possible combinations of two numbers and then count the number of combinations that result in a sum greater than 12.

The set contains four numbers, so there are 4 choose 2 possible combinations of two numbers, which is equal to (4! / (2! * (4 - 2)!)), or 6 combinations. These combinations are:

(0,6), (0,12), (0,15), (6,12), (6,15), (12,15)

Next, we'll count the number of combinations that result in a sum greater than 12. These combinations are:

(6,15), (12,15)

There are 2 combinations that result in a sum greater than 12.

Finally, to find the probability, we'll divide the number of favorable outcomes (combinations with a sum greater than 12) by the total number of outcomes (all possible combinations of two numbers), and express the result as a fraction:

probability = 2 / 6

Reducing the fraction, we get:

probability = 1 / 3

So, the probability that the sum of two randomly selected numbers from the set is greater than 12 is 1/3.

That's how you find the probability of the sum of two randomly selected numbers from a set being greater than a certain value. By counting the number of favorable outcomes and dividing by the total number of possible outcomes, you can find the probability of a certain event.

Answer:

(-4,-2)

Step-by-step explanation:

Answer: (-4,-4)

Step-by-step explanation: the y- coordinate stays the same you would have to move the x-coordinate only which would give you -4. Because you are adding 2 to -6.

The linear equation can be written as:

y = (3/2)*x - 21/5

A general linear equation can be written as:

y = m*x + b

Where m is the slope and b is the y-intercept.

First, we know that our line has the same slope than:

3x - 2y = 12

Rewriting that we will get:

3x - 2y = 12

3x - 12 = 2y

(3/2)x - 12/2 = y

So the slope of this line is (3/2).

And our lie has the same y-intercept as 5y + 21 = 4x

We can rewrite that to get:

5y = 4x - 21

y = (4/5)x - 21/5

The y-intercept is -21/5

Then the linear equation is:

y = (3/2)*x - 21/5

The rate of the passenger's train is given as follows:

60 miles per hour.

Velocity is distance divided by time, hence the following equation is built to model the relationship between these variables:

v = d/t.

For the passenger train, the equation is given as follows:

v = 240/t.

vt = 240

t = 240/v.

For the freight train, the velocity is 20 miles slower than for the passenger train, hence:

v - 20 = 160/t

v = 160/t + 20.

Replacing the first equation into the second, the rate of the passenger train is obtained as follows:

v = 160v/240 + 20

v = 2v/3 + 20

v/3 = 20

v = 60 miles per hour.

Answer:The answer is 20000

Step-by-step explanation:

The volume of the composite figure is 2592 cubic feet.

The area that any composite shape covers is known as the area of composite shapes. The composite shape is a shape created by joining a small number of polygons to create the desired shape. These shapes or figures can be constructed from a variety of shapes, including triangles, squares, quadrilaterals, etc. To calculate the area of a composite object, divide it into simple shapes such a square, triangle, rectangle, or hexagon.

The volume of the figure = Volume of the mounted object + Volume of the base object.

The volume of the mounted object is:

V = (l)(b)(h)

V = (9)(12)(6)

V = 648 cubic feet.

The volume of the base object is:

V = (l)(b)(h)

V = (27)(12)(6)

V = 1944 cubic feet.

The total volume of the composite figure is:

V = 648 + 1944

V = 2592 cubic feet

Hence, the volume of the composite figure is 2592 cubic feet.

The ansewr is C

Answer: 523.3cm^3

Step By Step Explanation:-The volume of a sphere can be calculated using the formula:

V = (4/3) * π * r^3

where r is the radius of the sphere. The diameter of the sphere is 10 cm, so the radius is half of that, or 5 cm.

Substituting the radius into the formula, we get:

V = (4/3) * π * (5 cm)^3

= (4/3) * π * 125 cm^3

= approximately 523.6 cm^3

So, the closest measurement to the volume of the sphere in cubic centimeters is approximately 523.3 cm^3.

The number of hours Maria rent the kayak for the paid amount of $40 when hourly rate is $5.50 is equal to 6 hours.

Fees of renting charges paid for kayaks from a local shop = $7

If the diameter of the tub is 8 inches, then the height of gallon tube is,  5.25 inches

Surface area is the sum of the areas of all the faces (or surfaces) of a three-dimensional object. It is a measure of how much area the surfaces of an object take up in two dimensions. The surface area of a solid can be found by adding up the areas of its faces.

The surface area of a cylinder can be expressed as:

SA = 2πr² + 2πr x h

where r is the radius of the cylinder, h is its height, and π is the constant pi (3.14).

The diameter of the tub is 8 inches, which means the radius is 4 inches. We are also given that the total surface area is 232.36 square inches.

So we can write:

232.36 = 2(3.14)(4²) + 2(3.14)(4)(h)

Simplifying and solving for h, we get:

232.36 = 100.48 + 25.12h

131.88 = 25.12h

h = 131.88/25.12

h ≈ 5.25 inches

Therefore, the height of the ice cream tub is approximately 5.25 inches.

Millimeter is the best unit to define the radius of the pencil.

The distance from a circle's centre to any point on its periphery is known as the radius. The radius of a circle is also known as the distance separating any two points on the circle from its centre. The radius of a circle is the separation between its centre and circumference. Always, the diameter is twice the radius. As a result, the formula is created by multiplying the diameter by two.

The smallest unit of measurement is the millimetre. There are a thousand millimetres in a metre, and a dime is somewhat thicker than a millimetre. When measuring anything's length in metric units, you'll be working with meters and variants on meters, including millimeters.
