To ride go carts at Rick's Play Zone, it costs $4 per ride plus $3 to rent a helmet. The total cost, y, in dollars, depends on x, the number of times you ride the go carts. Write an equation to represent this situation.

Reduced form of given fraction is (2 + n)/7

An expression or algebraic expression is any mathematical statement which consists of numbers, variables and an arithmetic operation between them.

Given expression

(2x + nx - 2y - ny)/(7x - 7y)

It can be written as

[(2x - 2y) + (nx - ny)]/(7x - 7y)

Factoring out common factors

[2(x - y) + n(x - y)]/7(x - y)

Again factoring out common factor

(x - y)(2 + n)/7(x - y)

(2 + n)/7

Hence (2 + n)/7 is reduced form of the given expression.

Answer:

89.28

Step-by-step explanation:

First lets find 7% of 96

96 x 0.07 = 6.72

then subtract 6.72 from 96

96-6.72=89.28

The requried, a number that is 7% smaller than 96 is approximately 89.28.

To find a number that is 7% smaller than 96, we need to calculate 7% of 96 and then subtract that value from 96.

Calculate 7% of 96.

7% of 96 = (7/100) * 96 = 0.07 * 96 = 6.72

To get a number that is 7% smaller than 96, we need to subtract the value we found in Step 1 from 96. subtract the calculated value from 96.

Number = 96 - 6.72 = 89.28

Therefore, a number that is 7% smaller than 96 is approximately 89.28.

A student taking thirteen credit hours should plan for approximately 13-15 hours of work outside of class each week.

Generally, if a student is taking thirteen credit hours, they should plan for approximately 13-15 hours of work outside of class each week. This includes attending lectures, studying, and completing assignments. To calculate this, the student should take the total number of credit hours (13) and multiply it by the number of hours per credit (usually 3 hours). This would give the student 39 hours of work outside of class.

However, this number should not be taken as an exact number, as the amount of time needed to complete the course may vary based on the student's learning style, the difficulty of the course, and the amount of time required for each assignment. For example, if a student is taking a particularly difficult course, they may want to plan for more hours than the calculation suggests.

In order to ensure success, students should plan ahead, create a schedule, and stick to it. This will help them stay on track and complete their coursework in a timely manner.

Step-by-step explanation:

There are 2,118,760 possible ways to select 6 cards from a deck of 52 cards if the spade ace must be selected.

If at all you must select the spade ace, you have 51 cards remaining from which to choose 5 more cards. The number of ways to choose 5 cards from 51 is 51C5, where C represents the number of combinations.

Using the formula for combinations, we have:

51C5 = 51! / (5! * (51 - 5)!) = 51! / (5! * 46!)

Using the factorial we can simplify this expression to:

51C5 = 51 * 50 * 49 * 48 * 47 / (5 * 4 * 3 * 2 * 1) = 2,118,760

The equivalent interest rate will be 0.5 % and it will be compounded 24 times

Compound interest is the interest you earn on interest. This can be illustrated by using basic math: if you have $100 and it earns 5% interest each year, you'll have $105 at the end of the first year. At the end of the second year, you'll have $110.25.

Compound interest is calculated by calculating the Amount

A = P( 1+r/n)^ ntp

A = amount

P is the principal

t is the time elapsed

since the interest rate is 6 % , the. monthly compounded interest will be 6/12, since there is 12 months in a year.

= 0.5 %

the number of times it will be compounded will be 12 × 2 = 24 times

therefore the equivalent interest rate is 0.5% per month and it will be compounded 24 times in the space of 2 years.

A reduced row echelon form of a matrix is a way to solve a system of linear equations. A reduced row echelon matrix has the following properties:

For a system of three equations and three variables with no solution, the reduced row echelon form of the augmented matrix would be in the form:

\begin{bmatrix}

1 & a & b & c \

0 & 0 & 0 & d \

0 & 0 & 0 & e

\end{bmatrix}

where a, b, c, d and e are constants and d and e are non-zero.

This form indicates that the system has no solution because the bottom row represents an equation that is false (0 = non-zero).

The reduced row echelon form of a matrix is a way to determine whether a system of linear equations has a solution. A system of linear equations has no solution if and only if the reduced row echelon form of the augmented matrix contains a row in the form of 0 = k, where k is non-zero.

In this case, the reduced row echelon form of the augmented matrix has the bottom row with the form 0 = d, and d is non-zero. This means that the equation is false, indicating that the system has no solution.

So, the fact that the bottom row of the reduced row echelon form has the form 0 = k, where k is non-zero, allows us to determine that the system of linear equations has no solution.

The distance of the parking lot from the first campsite is 3.14 miles.

The scale of the map is 1/24,000, which means that for every 1 inch on the map, it is equal to 24,000 inches in reality. To calculate the distance of the parking lot from the first campsite, we need to first convert the 8.3 inches on the map into inches in reality. To do this, we use the formula:

Actual distance = Map distance x (Map scale)

Actual distance = 8.3 inches x 24,000 inches

Actual distance = 199,200 inches

Now, to convert inches to miles, we can use the formula:

Miles = Inches / 63360

Miles = 199,200 inches / 63360

Miles = 3.14 miles
