Mary ran 1 3/5 miles on Monday and 7 1/5 miles on Tuesday. How many times her Monday’s distance was her Tuesday’s distance?

By solving a system of equations we will see that the larger number is 21 and the smaller one is 6.

Let's define the variables:

x = smaller number

y = larger number.

We know that the larger of two numbers is 9 more than twice the smaller, so we can write:

y -2x = 9

The sum of the numbers is 3 less than five times the smaller.

x + y = 5x - 3

Then we have a system of equations:

y -2x = 9

x + y = 5x - 3

Now we can isolate y on the first equation to get:

y = 9 + 2x

We can substitute that on the other equation to get:

x + 9 + 2x = 5x - 3

3x + 9 = 5x - 3

9 + 3 = 5x - 3x

12 = 2x

12/2 = x

6 = x

And the value of y is:

y = 9 + 2x

y = 9 + 2*6 = 21

These are the two numbers.

What does a math equation mean?

A mathematical statement that shows the equality of two mathematical expressions is the definition of an equation in algebra. As an illustration, the two equations 3x + 5 and 14 are joined by the equal sign to get the equation 3x + 5 = 14.

3.89y + 122.42x = 2882.48

We also know that y = x + 189

We can substitute the second equation into the first equation:

3.89(x + 189) + 122.42x = 2882.48

Expanding and simplifying:

3.89x + 730.91 + 122.42x = 2882.48

x = (2882.48 - 730.91) / (3.89 + 122.42) = 22.98 days

So the renovation took 22.98 days.

 The binomial distribution is a discrete probability distribution used in probability theory and statistics to explain the number of successes in a set number of trials, where each trial can only result in success or failure. The probability mass function (PMF) shown below defines the binomial distribution as follows:

P(a) = ⁿСₐ * p^a* (1-p)^(n-a)

Where:

a: the number of successes in n trials

n: the total number of trials

p: the probability of success in one trial

ⁿСₐ : n! / (a! * (n-a)!)

      the binomial coefficient, which shows how many different ways there are to select k successes from n trials.

    A variety of phenomena, including coin tossing, die rolling, and other tests with a set number of trials and only two possible outcomes, can be usefully modelled using the binomial distribution.

In a blind tasting test, if participants are unable to distinguish between bottled and tap water, we can assume that their guesses are random. The probability of accurately predicting the type of water in this situation is 50%.

The likelihood that 8 out of 9 people will properly predict their water type is

The angle, ∠B has 2 possible angles, one is 41.81° and the other will be 138.19°

In ΔABC we have been given that

AB = 6 cm

BC = 9 cm

A formula for the area of a triangle is

1/2 X one side X oth sde X sin(common angle)

Hence if we consider AB and BC with common angle, ∠B we get

1/2 X 6 X 9 X sinB = 18

or, sinB = 18/27

or, sinB = 2/3

Now since sin is positive in 2 quadrants, we will have 2 possible values for ∠B

Answer: √196 = 14

Step-by-step explanation: mere guess

Answer:  In this question, we are trying to find the difference in price between one apple and one banana. We can set up a system of two equations with two variables to represent the information given in the problem. Let x be the price of one apple in cents and y be the price of one banana in cents.

The first equation represents the information that Dan paid $5.70 for 5 apples and 3 bananas:

5x + 3y = 570

The second equation represents the information that Chris paid $4.70 for 3 apples and 5 bananas:

3x + 5y = 470

We can use these equations to solve for the value of x (the price of one apple) in terms of y (the price of one banana).

We can use the first equation and solve for x:

5x = 570 - 3y

x = (570 - 3y)/5

We can then substitute this expression of x into the second equation:

3((570 - 3y)/5) + 5y = 470

By multiplying both sides of the equation by 5 and 3 respectively, we can get the equation in a form that we can solve for y and then substitute back for x.

We can solve for y by subtracting 3((570 - 3y)/5) from both sides:

5y = 470 - 3((570 - 3y)/5)

Expanding and simplifying the right side of the equation:

5y = 470 - 3(114 - y)

5y = 470 - 342 + 3y

y = (470 - 342)/8

We can substitute this value of y back into the first equation and solve for x

x = (570 - 3y)/5

x = (570 - 3(470 - 342)/8)/5

x = (570 - 441)/5

Therefore, the price of one apple is (570 - 441)/5 = 129 cents more than the price of one banana.

Step-by-step explanation:

The system of linear equations: 2x-y=18 & 4x-3y = 16 has no solution.

The system of linear equations has no solution if the equations are inconsistent, meaning that there is no set of values for the variables that satisfies all of the equations simultaneously. One way to check for inconsistency is to try to find the solution by solving for one of the variables in one equation and then substituting it into another equation to see if both equations are satisfied. If the equations yield different values for the same variable, then the system has no solution.

In this case, the system of linear equations:

2x-y=18

4x-3y = 16

Has no solution. We can solve for x in the first equation and then substitute it into the second equation. If the equation yields a different value for y, then the system has no solution.

2x-y=18

2x=y+18

x=y/2 + 9

Now, substituting x into the second equation:

4x-3y=16

4(y/2 + 9) - 3y = 16

2y + 36 - 3y = 16

-y = -20

This result implies that y is not a real number, so the system of equations has no solution.

The measure of the amount a figure is rotated about the center of rotation is called the angle of rotation. The angle of rotation is usually measured in degrees. We specify the degree measure and direction of a rotation.

90° clockwise rotation: (x,y) becomes (y,-x)

90° counterclockwise rotation: (x,y) becomes (-y,x)

180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y)

270° clockwise rotation: (x,y) becomes (-y,x)

270° counterclockwise rotation: (x,y) becomes (y,-x)

Given data ,

Let the point be represented as P

The coordinates of P = P ( 5 , 2 )

The number of times more intense that the earthquake in Alaska was than the one in Japan was 1, 000 times more intense.

The Richter magnitude is determined by measuring the height of the greatest wave that has ever been seen at a given distance from the seismic source.

Each order of magnitude is 10 times more intense than the previous one since the Richter scale is a base-10 logarithmic scale. To put it another way, a two is ten times as intense as a one, and a three is one hundred times stronger.

This means that the number of times more intense that the earthquake in Alaska was than the one in Japan was:

The angle of elevation to the balloon of the runner the greatest distance from the balloon is 83.13 degrees.

The concept used in this problem is Trigonometry. Specifically, the problem uses the tangent function, which is one of the three main trigonometric ratios (sine, cosine, and tangent) used to relate the angles and sides of a right triangle.

To solve this problem, we can use the tangent function of trigonometry, which relates the opposite side (the distance from the runner to the balloon) to the adjacent side (the distance from the runner to the point on the highway) and the hypotenuse (the distance from the point on the highway to the balloon).

Let's call the angle of elevation of the runner closest to the balloon as angle A and the angle of elevation of the runner farthest from the balloon as angle B.

tan(A) = opposite / adjacent = (1500 - 421.2) / 421.2 = 878.8 / 421.2

tan(B) = opposite / adjacent = (1500 + 421.2) / 421.2 = 1921.2 / 421.2

We can use the inverse tangent function (arctan) to find the angle of elevation of the runner the greatest distance from the balloon.

B = arctan(1921.2 / 421.2)

The result is in radians, to convert the angle from radians to degrees, we can use the conversion factor of 180/pi.

B = arctan(1921.2 / 421.2) = arctan(4.5536) = 83.13 degrees (approx)

so, the angle of elevation to the balloon of the runner the greatest distance from the balloon is 83.13 degrees.
