What is the value of Cosec²a Cot²a?.

The equation -3p + (1/8) = (- 1/4) holds true for p = 0.125.

The equation is as follows:

-3p + ( 1/8 ) = ( - 1/4 )

The denominators of the two terms are different on the left-hand side of the equation.

The LCM of 1 and 8 is therefore 8.

Therefore,

- 3p × ( 8 / 8 ) + ( 1 / 8 ) × ( 1 / 1 ) = ( - 1 /4 )

- 24p / 8 + 1 / 8 = - 1 / 4

( - 24p + 1 ) / 8 = - 1 / 4

Add 8 to both sides of the equation now.

We get,

[ ( - 24p + 1 ) / 8 ]

× 8 = ( - 1 / 4 ) × 8

- 24p + 1 = - 8 / 4

- 24p + 1 = - 2

Add 1 to each side of the equation, then

- 24p + 1 - 1 = - 2 - 1

-24p = - 3

Subtract 24 from each side of the equation now.

- 24p / 24 = - 3 / 24

- p = ( - 1 / 8 )

On each side of the equation, multiply by -1.

( - p ) × ( - 1 ) = ( - 1 / 8 ) × ( - 1 ) ( - 1 )

p = 1 / 8

p = 0.125

The equation will be true for p = 0.125.

No, 45 and 36 are not a Co-prime numbers, because the two numbers have a common prime factor i.e., 9 .

A co-prime number is a number that has exactly one common divisor, which is 1. This means that a pair of numbers is co-prime if their greatest common divisor is 1. Consider x and y are two positive integers, they are called relatively prime if and only if their only common divisor is 1, so gcd(x, y) = 1. There are two numbers 45 and 36. First we determine the divisors of both numbers, then check the greatest common divisor. So, the factors of 45 are 1,3,5,9,15,45.

=> 45 = 1× 3×3× 5

and factors of 36 are 1, 3,2,4,6,9,12,36

=> 36 = 1×2×2×3×3

The tip left by the family at the restaurant is 18.48% of the total bill.

To determine the percentage of the tip, we need to divide the amount of the tip by the total bill, and then multiply by 100 to get the percentage.

The amount of the tip can be calculated by subtracting the cost of the bill from the total amount paid: $49.77 - $42 = $7.77

So the percentage of the tip is:

$7.77 / $42 x 100 = 18.48%

Therefore, the tip left by the family at the restaurant is 18.48% of the total bill.

The percentage is a relative term that expresses a number as a fraction of 100. It is commonly used to express a proportion or rate in terms of a hundred.

Yes, Y = -3x + 10 is a linear function.

A linear function is a function that can be written in the form of y = mx + b, where m is the slope (or rate of change) and b is the y-intercept (the point where the line crosses the y-axis). The equation Y = -3x + 10 can be written in this form, with m = -3 (the coefficient of x) and b = 10 (the constant term).

Linear functions represent straight lines on a graph, and their slope and y-intercept can be used to determine the characteristics of the line, such as its direction and position. In this case, the slope of the function is -3, which means that for every unit increase in x, there is a corresponding decrease of 3 units in y. The y-intercept of this function is (0,10), which means that the line crosses the y-axis at the point (0, 10)

In summary, Y = -3x + 10 is a linear function because it can be written in the form of y = mx + b, and it represents a straight line on a graph.

By applying the division formula, the number of times the ferry crossed the river would be 6 times.

To divide something means to split it into two or more equal pieces, areas, classes, categories, groups, or divisions. Dividing something means to give each component to a separate group, or to create equal parts from the whole. When doing division, the resulting value may or may not be an integer. The final result may occasionally be expressed as a decimal.

To calculate the division, we can use this following formula:

Dividend ÷ Divisor = Quotient + Remainder.

Where:

Dividend = the number, which is being divided

Divisor = the number, which divides the number (dividend) into equal parts

Quotient = the result of the division operation

Remainder = the leftover number in the division operation.

The initial value of b = $3.50 represents the cost of renting skates, while the rate of change m = $3.0 represents the rate per hour.

The initial value, b = $3.50 is the skate rental fee

The rate of change, 'm' is $3.0 is the hourly rate charged by the roller skating rink based on the query we have;

The roller skating rink's fees are comprised of a skate rental fee and an hourly rate.

Skating for two hours will cost you a total of $9.50.

Five hours of skating will cost you $18.50 in total.

Skating's overall cost and its duration in hours are related in a linear fashion.Let 'x' be the number of hours spent skating, and 'y' denote the overall cost;

The equation has the form y = mx + b.

Where;

m = The linear relationship's rate of change

b = The starting point (y-intercept)

X = 2 and Y = 9.50

Consequently, we can write;

9.50 = 2·m + b..(1) (1)

X = 5 and Y = 18.50

Consequently, we can write;

18.50 = 5·m + b..(2) (2)

Equation (1) minus equation (2) results in;

18.50 - 9.50 = 5·m - 2·m + b - b = 3·m

9.0 = 3 × m

∴ m = 9.0/3 = 3.0

m = 3.0 is the rate of change.

Likewise, we have;

We obtain from equation (1);

9.50 = 2·m + b = 2 × 3.0 + b = 6.0 + b

9.50 = 6.0 + b

∴ b = 9.50 - 6.0 = 3.50

The starting point is 3.50.

As a result, the initial value of b = $3.50 represents the cost of renting skates, while the rate of change m = $3.0 represents the rate per hour.

The average age of the zebras at the zoo can be found by adding up all of the ages and dividing by the number of zebras.

In this case, the ages of the zebras are 8, 11, 17, 7, 19.

To find the average age, we add up all of the ages: 8 + 11 + 17 + 7 + 19 = 62

Then we divide by the number of zebras (5): 62/5 = 12.4

So, the average age of the zebras at the zoo is 12.4 years old.

To find the standard deviation, we first need to find the variance.

The variance is the average of the squared differences from the mean.

We can find the variance by taking each value, subtracting the mean, squaring the result, and dividing by the number of zebras.

The standard deviation is the square root of the variance

So, the standard deviation of the zebras age is difficult to calculate by hand, but we can use a calculator to find the standard deviation, which is approximately 4.345 years.

Rounding to the nearest tenth:

The average age is 12.4 years old

In our question, it is given that the Checkpoint 4 value is -99 and the Checkpoint 3 value is -207.

We will use Subtraction. What is Subtraction?

The process of subtracting one number from another is called subtraction. The way to calculate the difference between two numbers is by using the basic arithmetic operation of subtraction, which is represented by the symbol (-).

The operation of subtraction is used to calculate the difference between two numbers. If you have an object group and remove a couple of them, the object group gets smaller. For instance, your friends consumed 7 of the 9 cupcakes you purchased for your birthday party. You are now down to two cupcakes. This can be expressed as a subtraction formula: 9 - 7 = 2, which means "nine less seven equals two." The result of subtracting 7 from 9 is 2, or (9 - 7) Here, we divided two numbers, 9, and 7, by one another to get the difference of 2.

Subtracting the value of Checkpoint 3 from Checkpoint 4, we get:

Checkpoint  - Checkpoint 3 = -207 -(-99)

= -207 + 99 = 108.

Therefore Checkpoint 4 will be higher than Checkpoint 3 by 108.
