The length of x to the nearest 10th of an inch is 7.1 inches.

A triangle is a two dimensional figure which consist of three vertices, three edges and three angles.

Sum of the interior angles of a triangle is 180 degrees.

We have law of sine of triangle, which states that,

sin X / x = sin Y / y = sin Z / z

where X, Y and Z are three angles of a triangle and x, y and z are the sides opposite to X, Y and Z respectively.

Using this,

Sin V / v = Sin W / w = Sin X / x

Given that, m ∠V = 76° and m ∠W = 44°

m ∠V + m ∠W + m ∠X = 180°

76° + 44° + m ∠X = 180°

m ∠X = 180° - ( 76° + 44° )

m ∠X = 60°

Also, given that, v = 7.9 inches

Sin V / v = Sin X / x

sin (76°) / 7.9 = sin (60°) / x

x = [sin (60°) × 7.9] / sin (76°)

x = [0.866 × 7.9] / 0.970

x = 7.051 ≈ 7.1

Hence the length of the x is 7.1 inches to the nearest 10th of an inch.

Answer: 120 inches cubed

Step-by-step explanation:

If A is a m × n matrix, with columns a1, . . . , an, and if b is in R

m,

then the matrix equation

Ax = b

has the same solution set as the vector equation

x1a1 + x2a2 + · · · + xnan = b

which, in turn, has the same solution set as the system of linear

equations whose augmented matrix is

a1 a2 · · · an b.

The equation Ax = b is consistent if−2b1 + b3 = 0.

(equation of a plane in R3)

x1a1 + x2a3 + x3a3 = b

if and only if b3 − 2b1 = 0.

Columns of A span a plane

in R3 through 0

Instead, if any b in R3

(not just those lying on a particular line or

The equation is 2000=5[tex](L-10)^{2}[/tex] to find the dimensions of the original cardboard piece.

If she is using a square piece of cardboard, then have in mind that we are dealing with a square of unknown length "L".

Now, consider that you are removing from each corner of that square a smaller square of surface 5 . Once the small 5 in size square pieces are cut, the four flaps that are left (see attached image) are bent through the lines pictured in grey so they form the final box.

Notice that the dimensions of this box will be:

Notice as well that the height of the box will be exactly 5 inches (the length of the square cutting).

This statement is TRUE. When we are doing a problem, we could use these questions " what is the equation asking you do? what is your plan to solve?" as the part of starting solving the problem in math about equation matter.

In mathematics, an equation is an equation statement that contains one or more variables. Solving equations consists of determining which variable values makes an equality true. The variable is also called "unknown" and the value of an "unknown" that satisfies the equation is called the equation solution. There are two types of equations: identity and conditional equations. True identity for all variable values. The conditional equation is true only for certain variable values.

An equation is a mathematical statement in the form of a symbol which states that two things are exactly the same. Equations are written with an equal sign (=), as follows:

The midpoint between a celestial body's greatest and smallest separations from its primary.

The metre is the SI unit for distance (m). Long distances can be measured in kilometres, whereas little distances can be gauged in millimetres (cm) (km).

Distance between P and Q if two points are given P([tex]x_{1}[/tex], [tex]y_{1}[/tex]) and Q([tex]x_{2}[/tex], [tex]y_{2}[/tex]) , PQ = [tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]

The lattice point of the inverse is (3, 0).

To find the lattice points of the inverse of the function f(x), we need to find the points where both x and y are integers.

To find the inverse of the function, we switch the x and y values, then solve for y:

y = log2(-x + 3) - 4

x = log2(-y + 3) - 4

y = 3 - 2^(x + 4)

For x and y to be integers, both 2^x and - 2^(x + 4) must be integers.

This occurs when y is a positive integer and y <= 2, since 2^y becomes larger than 3 for y > 2.

Thus, the only lattice point of the inverse is (3, 0).

There are 214 distinct paths from (-1,2,0) to (1,3,7) in Euclidean three-space.

We can approach this problem using a combinatorial approach.

Let's say that there are a total of n moves from the starting point (-1,2,0) to the ending point (1,3,7). Then, the number of H moves is nh, the number of V moves is nv, and the number of A moves is na, where nh + nv + na = n.

The starting point (-1,2,0) is (1,1,7) moves away from the ending point in the x, y, and z directions, respectively. Therefore, we have the following constraints:

   nh ≥ 1 (to move from x = -1 to x = 1)

   nv ≥ 1 (to move from y = 2 to y = 3)

   na ≥ 7 (to move from z = 0 to z = 7)

The number of distinct paths from (-1,2,0) to (1,3,7) is simply the number of ways to choose nh, nv, and na moves from n total moves such that the constraints are satisfied. This is equivalent to finding the number of solutions to the equation nh + nv + na = n subject to the constraints.

Using the stars and bars technique, the number of solutions can be calculated as:

C(n - 1, 2) = C(n - 1, n - 3) = C(n - 1, na - 1)

where C(n, k) is the binomial coefficient representing the number of ways to choose k items from a set of n items.

Since na ≥ 7, we can start by setting na = 7 and then increasing it by one to see if there are additional solutions. For na = 7, n = 7 + nh + nv. Therefore, n >= 8 and n <= 14. The number of solutions for each value of n can be calculated using the formula above, and the total number of solutions can be obtained by summing up the results for each value of n.

For example, when n = 8, there are C(7, 2) = 21 solutions, when n = 9, there are C(8, 2) = 28 solutions, and so on. The final answer is the sum of all the solutions, which is:

21 + 28 + 35 + 35 + 28 + 21 + 13 + 6 = 214

Therefore, there are 214 distinct paths from (-1,2,0) to (1,3,7) in the Euclidean three-space.

A simple method for adding and subtracting fractions with unlike denominators:

Find a common denominator: The first step is to find a common denominator that is a multiple of both denominators. The smallest common denominator is usually the least common multiple (LCM) of the two denominators.

Convert the fractions to equivalent fractions with the common denominator: Once you have a common denominator, you can convert each fraction to an equivalent fraction with the same denominator by multiplying the numerator and denominator by the same number.

Add or subtract the numerators: Once both fractions have the same denominator, you can add or subtract the numerators to get the numerator of the resulting fraction.

Simplify the resulting fraction: Finally, simplify the resulting fraction by dividing both the numerator and denominator by their greatest common factor, if possible.

Here is an example:

To add 1/3 + 1/4, we first find a common denominator:

The LCM of 3 and 4 is 12, so we multiply both the numerator and denominator of each fraction by 4 to get 12/12 as the common denominator:

1/3 * 4/4 = 4/12

1/4 * 3/3 = 3/12

Next, we add the numerators:

4/12 + 3/12 = 7/12

Finally, we simplify the fraction:

7/12 = (7 ÷ 1) / (12 ÷ 1) = 7/12.

So the result is 7/12.

Answer:

When you rotate a figure around a center point other than the origin, the resulting image is translated or shifted from the original figure's position. This happens because the center of rotation affects the position of the figure after the rotation is performed.

If you rotate a figure around a center point that is not the origin, the figure will still undergo a rotation, but the position of the rotated figure will depend on the location of the center point. The center point of rotation acts as a pivot point and determines the new location of the rotated figure.

In summary, rotating a figure around a center point other than the origin will result in a translated image that is shifted from the original position of the figure. The amount of translation will depend on the location of the center of rotation.

A probability is a number that reflects the chance or likelihood that a particular event will occur. Probabilities can be expressed as proportions that range from 0 to 1, and they can also be expressed as percentages ranging from 0% to 100%

Probability = the number of ways of achieving success. the total number of possible outcomes. For example, the probability of flipping a coin and it being heads is ½, because there is 1 way of getting a head and the total number of possible outcomes is 2 (a head or tail). We write P(heads) = ½ .

The formula for probability states that the possibility of an event happening, or P(E), equals the ratio of the number of favorable outcomes to the number of total outcomes. Mathematically, it looks like this: P(E) = favorable outcomes/total outcomes​

Probability p of a rainy day is 0.25
