In 1957 an earthquake in Alaska measured about 9.0 on the Richter scale. An earthquake with magnitude 6.0 occurred in Japan in early 2007.
How many times more intense was the earthquake in Alaska than the one in Japan?
The number of times more intense that the earthquake in Alaska was than the one in Japan was 1, 000 times more intense.
How does the Richter Scale work ?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:
= 10 x 10 x 10
= 1, 000 times
Note : Alaska and Japan earthquake difference:
= 9 - 6
= 3

The cafeteria sells each apple at one price and each banana at another price. For 5 apples and 3 bananas Dan pays $5.70. For 3 apples and 5 bananas Chris pays $4.70. The price of one apple is how much more then the price of one banana, in cents?
In this question, why do you multiply by 5 to the top equation and 3 to the bottom equation?
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.

Let's call the number of days of labor x, and the number of square feet y.
From the information provided, we can set up the following equation:
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

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

621900 house cost 5.4 mortgage interest rate how  much do you have to pay monthly over 5 years
Over a period of 5 years, the amount that you would have to pay monthly is given as $3,201.37
How to solve for the mortgageTo calculate the monthly mortgage payment for a house that costs $621,900 with an interest rate of 5.4% over 5 years, you can use the following formula:
P = (r(1 + r)^n) / (((1 + r)^n) - 1) * L
Where:
P = monthly payment
r = monthly interest rate (5.4%/12 = 0.0045)
n = total number of payments (5 years x 12 = 60)
L = the loan amount ($621,900)
Plugging in the values, we get:
P = (0.0045(1 + 0.0045)^60) / (((1 + 0.0045)^60) - 1) * 621,900
P = $3,201.37

two runners on an east-west highway are 421.2 feet apart heading east. a hot air balloon is flying ahead of them. the angle of elevation to the balloon of the runner closet to the balloon is 24.5o. if the hot air balloon is 1500 feet directly above a point on the highway east of both runners, what is the angle of elevation to the balloon of the runner the greatest distance from the balloon?
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.

In concave equilateral pentagon ABCDE, angle A = angle B = 108 degrees. What is the degree measure of angle E?
Answer:
In an equilateral pentagon, all angles have equal degree measures, so to find the degree measure of one angle, we need to find the sum of the degree measures of the interior angles and then divide by the number of angles.
Step 1: Find the sum of the degree measures of the interior angles of the pentagon:
180 * (5 - 2) = 540 degrees
Step 2: Divide the sum by the number of angles:
540 degrees / 5 angles = 108 degrees
The degree measure of angle E is 108 degrees.
The degree measure of angle E is 108°.
We can use interior angels theorm.
The sum of the interior angles of a pentagon can be calculated using the formula:
Interior angle sum = (n - 2) × 180
where n is the number of sides of the polygon.
In this case, n = 5, so the sum of the interior angles of the pentagon is (5 - 2) × 180 = 540°.
Since angle A and angle B are both equal to 108°, we can say that:
angle A + angle B = 2 × 108 = 216°.
So, the sum of the remaining three interior angles (angles C, D, and E) is:
540 - 216 = 324°
Since each of these three angles is equal, the measure of each angle must be 324° divided by 3, or:
324 ÷ 3 = 108°
So, the degree measure of angle E is also 108°.

Jeff wants to purchase a television for his first apartmentThe television costs 750. He can get a zerointerest loan for the television if he pays $100 per month. At the same time, he puts away $200 per month in savings. To figure out when his savings will equal the remaining amount he owes on the television , he starts writing a system of equations :
The correct equation for Jeff after every cost will be y = 750 -100x
Cost of the television = $750
Loan amount paid per month = $100
Amount put in savings = $200
A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions.
Since the amount of $200 is being saved, this means that it is not going away or is being spent. Now, as per the question, the initial remaining balance with Jeff is 750. The balance decreases by the loan amount of 100 per month.
This means that the amount is reduced by = 100x.

By solving a system of equations we will see that the larger number is 21 and the smaller one is 6.
How to find the two numbers?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

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
(1/2)^8 * (1/2)^1 = (1/2)^9 = 1/512
