Grace rides her horse 36 miles in 2 hours 15 minutes. what is the average speed in miles per hour? The correct answer and explanation is: To find the average speed, use the formula for speed, which is: Average Speed=Total DistanceTotal Time\text{Average Speed} = \frac{\text{Total Distance}}{\text{Total Time}} In this case, the total distance is 36 miles, and the […]

The contract efficiency role of accounting is associated with The correct answer and explanation is: The contract efficiency role of accounting is associated with reducing information asymmetry and ensuring that all parties involved in a contract have access to the same, accurate financial information. This function helps in achieving more efficient contracts by providing a

All halogens are highly reactive. What causes these elements to have similar chemical behavior? The correct answer and explanation is: Halogens are highly reactive due to their similar electronic configurations. All halogens belong to Group 17 of the periodic table, which means they have seven electrons in their outermost electron shell. This configuration is just

Write 4x + 3y = 6 in the form y = mx + b. The Correct Answer and Explanation is: To rewrite the equation 4x+3y=64x + 3y = 64x+3y=6 in the form y=mx+by = mx + by=mx+b, which is the slope-intercept form of a linear equation, we need to isolate yyy on one side of

4x + 3y = 6 -4x + 2y = 14 Solve the system of equations. The Correct Answer and Explanation is: We have the following system of equations: We will solve this system using the elimination method. The idea is to manipulate the equations such that one of the variables cancels out when the equations

Give your answer in the form (x, y) and leave any fractions in fraction form. Provide your answer below: FEEDBACK MORE INSTRUCTIONS Content attribution The Correct Answer and Explanation

When 1,3 -butadiene reacts with one mole of HBr, two isolable products result. Propose a mechanism to explain this. The Correct Answer and Explanation is: When 1,3-butadiene reacts with one mole of HBr, the reaction proceeds through an electrophilic addition mechanism, leading to two different products due to the possibility of two carbocation intermediates forming

Explain the instruction ( fliplr) with example? Your answer The Correct Answer and Explanation is: The instruction fliplr stands for “flip left to right” and is commonly used in programming, especially in MATLAB and other languages like Python, to reverse the elements of an array or matrix along the horizontal axis (left to right). When

The Correct Answer and Explanation is: Correct Answer:6x² + 23x – 18 Explanation: The problem requires us to multiply two binomials, (3x – 2) and (2x + 9), and express the result as a trinomial, which is a polynomial with three terms. A common and reliable method for multiplying two binomials is the FOIL method.
