Using the simplification of an equation we can get the value of x to be,

x = 10 2/11.

Equations are mathematical statements with the equals (=) symbol and two algebraic expressions on either side. This illustrates the equality of the relationship between the expressions printed on the left and right sides. The formula LHS = RHS (left hand side equals right hand side) is utilised in all mathematical equations. To determine the value of an unknown variable that represents an unknown quantity, you can solve equations. A statement is not regarded as an equation if it has no "equal to" symbol. It'll be regarded as a term.

Here in the question,

The given equation is:

(x-4 8/11) + 1 9/11= 7 3/11

Simplifying it, we get:

(x - 52/11) + 20/11 = 80/11

Subtracting 20/11 from both sides:

x - 52/11 = 60/11

Adding 52/11 on both side:

x = 112/11

x = 10 2/11

Answer:

2π inches or approximately 6.28 inches

Step-by-step explanation:

The formula for the arc length of a circle is:

arc length = (central angle / 360) x 2πr

where r is the radius of the circle.

Plugging in the given values, you get:

arc length = (60/360) x 2π(6)

arc length = (1/6) x 12π

arc length = 2π

So, the measure of the arc length associated with a central angle of 60° and a radius of 6 inches is 2π inches or approximately 6.28 inches.

Answer: Let u = ln(x). Then, we have:

y = y(u)

dy/dx = dy/du * du/dx = dy/du * (1/x)

d^2y/dx^2 = d/dx (dy/du * du/dx) = d^2y/du^2 * (1/x)^2 - dy/du * (1/x^2)

Substituting these into the original differential equation yields:

d^2y/du^2 - dy/du + (4 - e^u)y = e^(2u)

This is now a second-order ordinary differential equation in y with constant coefficients, which can be solved using standard methods such as the characteristic equation or undetermined coefficients.

The answer is C. 60(x-3)=45x. This equation is based on the information that the 45 expensive wood costs $3.00 more than the 60 cheap wood. In other words, if the price of the 60 cheap wood is x, the price of the 45 expensive wood is x + 3.

Algebra involves working with numbers, equations, and variables to solve real-world problems and understand abstract relationships.

To solve this equation, we must use algebra and solve for x. First, we multiply both sides of the equation by 4/5. This gives us:

48x + 36 = 45x

-36 = 3x

Finally, we divide left side of the equation by 3, giving us the final solution:

x = -12

Therefore, the price of the 60 cheap wood is $12, and the price of the 45 expensive wood is $15. This equation shows the correct relationship between the two types of wood that the contractor purchased.

The simplest form of the radical expression (√2 + √3) / (√2 - √3) is -5 - 2√6.

Given the radical expression in the question;

(√2 + √3) / (√2 - √3)

To simplify the expression, we need to eliminate the radical in the denominator.

We can do this by multiplying both the numerator and denominator by the conjugate of the denominator, which is (√2 + √3):

[(√2 + √3) / (√2 - √3)] × [ (√2 + √3) / (√2 + √3) ]

= (2 + √6 + √6 + 3) / (2 - √9)

= (5 + 2√6) / (2 - 3)

= (5 + 2√6) / (-1)

= -5 - 2√6

it will take you approximately 31.4 seconds  to run around the baseball field at a rate of 9 feet per second.

The time it takes to run around the baseball field will depend on the distance around the field.

Assuming the field is a perfect circle and has a diameter of 90 feet (which is a common size for a baseball field).

The circumference of a circle with diameter 90 feet is:

C = πd = π(90) = 90π feet

To run around the perimeter of the baseball field, you will need to cover a distance of 90π feet.

Using the formula:

time = distance / rate

we can calculate the time it takes to run around the baseball field:

time = (90π feet) / (9 feet/second)

time = 10π seconds

time ≈ 31.4 seconds (rounded to the nearest tenth of a second)

Therefore, it will take you approximately 31.4 seconds (rounded to the nearest tenth of a second) to run around the baseball field at a rate of 9 feet per second.

Answer:

The surface area of the triangular prism is approximately 16.222 square feet, and the volume of the triangular prism is 12 cubic feet.

Step-by-step explanation:

formulas:

Surface Area = 2B + Ph

Volume = Bh

where B is the area of the triangular base, P is the perimeter of the base, h is the height of the prism, and B and h are both in the same units (inches, feet, etc.).

Given:

Height of the triangular prism = 1 foot

Base of the triangular prism = 6 inches

Height of the triangular base = 4 inches

Length of the other two sides of the triangular base = 5 inches

First, we need to find the area of the triangular base (B):

B = (1/2) x base x height

B = (1/2) x 6 inches x 4 inches

B = 12 square inches

Next, we need to find the perimeter of the triangular base (P):

P = sum of all three sides

P = 6 inches + 5 inches + 5 inches

P = 16 inches

Now, we can use the formulas to find the surface area and volume:

Surface Area = 2B + Ph

Surface Area = 2(12 square inches) + (16 inches)(1 foot)

Surface Area = 24 square inches + 16 square feet

Surface Area = 16.222 square feet (rounded to three decimal places)

Volume = Bh

Volume = 12 square inches x 1 foot

Volume = 12 cubic feet

Therefore, the surface area of the triangular prism is approximately 16.222 square feet, and the volume of the triangular prism is 12 cubic feet.

Reading, writing, and mathematics are, or should be, inseparable. Hands-on mathematics can stimulate curiosity, engage student interest and build important prior knowledge before students read or write about the topic. The more students know about a topic, the better they comprehend and learn from text on the topic. Prior knowledge is the strongest predictor of student ability to make inferences from text.

Hands-on mathematics, though, must be combined with minds-on activities. Reading and writing activities can help students analyze, interpret and communicate mathematical ideas. These are skills needed to evaluate sources of information and the validity of the information itself, a key competency for mathematically literate citizens.

Many of the process skills needed for mathematics are similar to reading skills and, when taught together, would reinforce each other. Examples of common skills are predicting, inferring, communicating, comparing and contrasting, and recognizing cause and effect relationships. Teachers who recognize the interrelatedness of mathematics and literacy processes can design instruction that reflects these similarities. Becoming a Nation of Readers suggests that the most logical place for instruction in most reading and thinking strategies is in the content areas rather than in separate lessons about reading.

The importance of writing in the mathematics classroom cannot be overemphasized. In the process of writing, students clarify their own understanding of mathematics and hone their communication skills. They must organize their ideas and thoughts more logically and structure their conclusions in a more coherent way. Competency in writing can only be accomplished through active practice; solving mathematics problems is a natural vehicle for increasing students’ writing competence.

The total number of players at the baseball game was 16.

To solve this problem, we can use a proportionality equation.

If we let "p" be the total number of players at the baseball game and "y" be the number of players who chose a bottle of water, we can set up the equation:

y ÷ p = 3 ÷ 4

According to the problem statement, 12 players chose a bottle of water, which is 3/4 of the total number of players.

So we can substitute that in:

12 ÷ p = 3 ÷ 4

To solve for "p", we can cross-multiply and simplify:

12 × 4 = 3 × p

48 = 3 × p

p = 48 ÷ 3

p = 16

For equation log y = -0.02396x + 4.8153 the value of y when x = 0 is 6842.9.

The number -0.02396 is the slope of the line in the linearized equation. Since it is negative, this tells us that there is a negative correlation between x and y in the original data set.

In other words, as x increases, y decreases.

b. When x = 0, the term -0.02396x becomes 0

so the equation becomes:

log y = 4.8153
