Just write the number in a calculator and press equal. It'll give you the number in fraction

Answer:

So, the rational number is \(\frac{52}{12}\) .

Step-by-step explanation:

Let x be the other number.

We know ,

\(\frac{7}{36}\) + x = \(\frac{5}{6}\)

To find x, we need to convert both to have a common denominator.

So, if we multiply \(\frac{7}{36}\) by \(\frac{10}{36}\)  ,

\(\frac{10}{1}\) × \(\frac{7}{36}\) + x = \(\frac{56}{10}\)

After multiplication the fraction  \(\frac{7}{36}\) becomes \(\frac{70}{360}\)  .

\(\frac{70}{360}\)+ x =  \(\frac{56}{10}\)

Now we have common denominator of 360in both fraction,

Now,

we can simplify the equation ,

\(\frac{70}{360}\)  + x = \(\frac{56}{10}\)

70 + 360x = 56 × 36

2520 + 360x = 2016

504 + 360x = 2016

360x = 1512

x = \(\frac{1512}{360}\)

   =\(\frac{52}{12}\)

So, the rational number is \(\frac{52}{12}\) .

Consider the complete question is "Ben, Cam, and Justin are lumberjacks. The number of trees they chop down is given by b+2c+3j, where b is the number of hours Ben spends chopping, c is the number of hours Cam spends chopping, and j is the number of hours Justin spends chopping. How many trees do they chop down after Ben spends 8 hours chopping, Cam spends 3 hours chopping, and Justin spends 4 hours chopping?"

Given:

Total number of trees chopped by them = \(b+2c+3j\)

b = number of hours Ben spends chopping = 8

c = number of hours Cam spends chopping = 3

j = number of hours Justin spends chopping = 4

To find:

The numerical value of total number of trees chopped by them.

Solution:

Total number of trees chopped by them = \(b+2c+3j\)

Put \(b=8, c=3\) and \(j=4\) in the given expression.

\(Total=8+2(3)+3(4)\)

\(Total=8+6+12\)

\(Total=26\)

Therefore, total number of trees chopped by them is 26.

The number of dimes Joe has is 6.

Joe has dimes and nickels, the total amount is $1.45

We have to find the number of dimes Joe has.

Suppose the number of dimes is d, so we have the number of nickels is 2d + 5

Now from the question, we get an equation:

0.10d + 0.05( 2d+ 5) = $1.45

To know the value of d we need to solve the equation:

0.10d + 0.10d + 0.25 = 1.45

0.20d = 1.20

d = 120/20

   = 6

Hence we get the total number of dimes Joe has is 6.

A direct relationship between two variables is reflected in a "POSITIVE" correlation coefficient.

Correlation is a statistical technique for measuring and describing the relationship between two variables.

The variables move in the same direction when they have a positive correlation. In other words, as one variable increases, so does the other, and conversely, as one variable decreases, so does the other.

Typically, the two variables are simply observed rather than manipulated. Two scores from the same individuals are required for the correlation.

Answer:

#9. y = -250x

#10. y = -2500, x = 100

Step-by-step explanation:

y = mx +b

y: y-value

m: slope

x: x-value

b: y-intercept

since your answer for #8 is -250, the slope would be -250 or m would be -250

y = -250x+b

now to solve for b, we take one of the points and plug it in, any works, but we'll use (1,-250)

plug in the points

-250 = -250(1)+b

solve for b

b = 0

thus the equation is y = -250x + 0 or y = -250x

#10 plug in x values and y values into equation to get answer

x = 10 -> y = -250(10) = -2500

y = -25,000 -> -25,000 = -250x

x = -25,000/-250

x = 100

The largest value of s is **0.25**.

We know that |f(x)-4| < 1/2 when 0 < |x-1| < s. This means that the distance between f(x) and 4 is less than 1/2.

We can see that this is true when 0 < |x-1| < 0.25. If |x-1| is greater than 0.25, then the distance between f(x) and 4 will be greater than 1/2.

Therefore, the largest value of s that satisfies the condition is 0.25.

The largest value of s is **1**.

We know that |f(x)-5| < 1 when 0 < |x-2| < s. This means that the distance between f(x) and 5 is less than 1.

We can see that this is true when 0 < |x-2| < 1. If |x-2| is greater than 1, then the distance between f(x) and 5 will be greater than 1.

Therefore, the largest value of s that satisfies the condition is 1.

The 3 sided die is a unique type of dice with three sides instead of the usual six, and the probability of rolling any of the sides is equal to 1/3 or 33.3%.

A 3 sided die, also known as a triangular or tetrahedral die, is a unique type of dice that has three sides instead of the usual six. It is often used in games, puzzles, and simulations that require a random number generator.

Mathematically speaking, the probability of rolling any of the three sides on a 3 sided die is equal to 1/3 or 33.3%. This is because each of the sides has an equal chance of landing face up when the die is rolled.

To calculate the probability of rolling a specific number on a 3 sided die, we divide the number of ways that number can appear by the total number of possible outcomes.

For example, if we want to know the probability of rolling a 2, we would divide 1 (since there is only one side with a 2) by 3 (the total number of sides on the die). This gives us a probability of 1/3 or 33.3%.

Step-by-step explanation:

I think thats right! If not, let me know.

When we calculate probabilities involving one event AND another event occurring, we multiply their probabilities.

According to me , independent is the word which is associated with multiplication when computing probabilities . Because when the events are independent then we multiply the probabilities .

According to the multiplication rule of probability, the probability of occurrence of both the events A and B is equal to the product of the probability of B occurring and the conditional probability that event A occurring given that event B occurs.

The probability of the union of two events is equal to the sum of individual probabilities. The union of two set contains all the elements of previous sets. The union is denoted by ∪. The equation for the students earnings will be expressed as P(A∪B). The occurrence of event A changes the probability of B then the events are dependent. If the probability of two events happening together is zero then the events are mutually exclusive.

The formula for the surface area of the box, in terms of the length of one side of the square base (s), is A = s^2 + 4s^2 = 5s^2.

The derivative of the surface area function with respect to s, denoted as dA/ds, gives us the rate of change of the surface area with respect to the length of one side of the base.

1. The surface area of the box consists of the area of the square base and the four equal sides. The area of the square base is s^2, and each side has a length of s. Therefore, the total surface area is given by A = s^2 + 4s^2 = 5s^2.

2. To find the derivative of the surface area function, we differentiate 5s^2 with respect to s using the power rule of differentiation. The power rule states that if we have a function f(x) = cx^n, then the derivative is f'(x) = cnx^(n-1).

  Applying the power rule, we have dA/ds = d(5s^2)/ds = 10s.

3. The derivative, dA/ds = 10s, represents the rate of change of the surface area with respect to the length of one side of the square base. This means that for every unit increase in s, the surface area increases by 10s units.

  The derivative does not provide information about minimizing the amount of material used. To find the dimensions of the box that minimize the amount of material used, we need to set up an optimization problem and solve for the critical points. This involves setting the derivative equal to zero and finding the values of s that satisfy this equation. However, since the problem statement does not provide a specific volume constraint or objective function, we cannot proceed with the optimization process.

Therefore, the temperature of the can of soda after 115 minutes is approximately 55°F, rounded to the nearest degree.

A mathematical equation is an expression with equality on both sides of the equal to sign that connects two other expressions. Think about the equation 3y = 16 as an illustration.

To find the value of k, we need to use the information given to solve for k in the equation T = Ta + (To - Ta) * \(e^(-kt)\), where T is the temperature of the can of soda, Ta is the ambient temperature (73°F), To is the temperature of the refrigerator (39°F), and t is the time elapsed in minutes.

We know that after 15 minutes, the temperature of the can of soda reaches 61°F, so we can substitute these values into the equation and solve for k:

61 = 73 + (39 - 73) * \(e^(-k * 15)\)

-12 = -34 * \(e^(-15k)\)

0.3529 =\(e^(15k)\)

㏒(0.3529) = 15k

k = -0.0301

So k is approximately -0.0301, rounded to the nearest thousandth.

To find the temperature of the can of soda after 115 minutes, we can use the same equation with the value of k we just found:

T = 73 + (39 - 73) * \(e^(-0.0301 * 115)\)

T = 73 + (-34) * \(e^(-3.47)\)

T = 73 + (-34) * 0.54

T = 54.62

Therefore, the temperature of the can of soda after 115 minutes is approximately 55°F, rounded to the nearest degree.
