Answer: The equation of a line in the form y = mx + b can be written as y - mx - b = 0. So we can rewrite the equation of the line as 2y - 3x + 5 = 0. This means that the slope of the line is -3/2.
The slope of a line perpendicular to this line would be the negative reciprocal of -3/2, which is 2/3. Let's call the point M (x, y). We know that the line passing through (2, 6) has a slope of 2/3. So we can write the equation of this line as:
y - (2/3)x - b = 0
Substituting the point (2, 6) into this equation, we get:
6 - (2/3)(2) - b = 0
b = 4
So the equation of the line passing through (2, 6) is:
y - (2/3)x - 4 = 0
To find the coordinates of point M, we need to find the point where these two lines intersect. Setting the two equations equal to each other and solving for x and y, we get:
2y - 3x + 5 = y - (2/3)x - 4
5 - 2y = y - (5/3)x + 4
(5/3)x = 3 - y
x = (3 - y) * (3/5)
Substituting this expression for x into one of the original equations, we can solve for y:
2y - 3((3 - y) * (3/5)) + 5 = 0
2y - (9 - 3y)(3/5) + 5 = 0
(10/5)y - (9/5) + 5 = 0
y = (9/5) + (5/5)
y = 2
Substituting this value for y back into the expression for x, we get:
x = (3 - 2) * (3/5)
x = 1
So the coordinates of point M are (1, 2).

The fourth term of an arithmetic sequence is 20. The common difference is -1/5 times the first term. What is the first term? Graph the sequence.
As a result, the first term of the answer to the given arithmetic mean problem is 14.
What does arithmetic mean?The Arithmetic Mean or Average of the Group is the product of the sum of all the numbers in a group and the amount of items in that list, divided by both. The Geometric progression is also same as this .This average of the numbers 5, 7, and 9 is, for instance, 4, as 5 + 7 + 9 is 21, and 21 split by 3 [there really are three numbers] equals 7.
Here,
In this case, t(n) = (a + ((n — 1) * d)),
The value of the nth term is t(n),
The first term of the AS is a.
The position of a value in the A.S. is represented by the positive whole integer n, and
The constant common difference among A.S. words is d.
In light of the question, we can say:
11 = (5 + ((4 — 1) * d)),
Take 5 away from both sides.
11 — 5 = (5 + ((4 — 1) * d)) — 5,
On the RHS, the fives cancel one another out.
6 = 3d,
d = 2.
In summary, the common distinction is: 2.
=> 20 = a + 3d
=> 20 - 6
=> a =14
As a result, the first term of the answer to the given arithmetic mean problem is 14.

Ann's car can go 210 miles on 6 gallons of gas. During a drive last weekend, Ann used 7 gallons of gas. How far did she drive?
Answer:
245 miles
Step-by-step explanation:
210 = 6 gallons
210/6 = how far you can travel with one gallon
210/6 = 35
7*35 = how far you can travel with 7 gallons
7*35 = 245
Answer:
Ann drove 245 miles during her drive last weekend.
Step-by-step explanation:
If Ann used 7 gallons of gas during her drive last weekend, we can use the car's MPG to find out how far she drove by multiplying the number of gallons used by the MPG:
7 gallons * 35 miles/gallon = 245 miles
Each other 11 letters of the word mathematics with written on a separate piece of paper and placed in a bowl what is the probability of drawing
Therefore, the probability of drawing "OBJ" from the bowl is (1/11) * (1/11) * (1/11) = 1/1331
Define Probability.The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
Define Statistics.The study of statistics focuses on gathering, organizing, organizing, analyzing, interpreting, and presenting data. It is customary to start with a statistical population or a statistical model to be researched when applying statistics to a scientific, industrial, or social problem.
The word "mathematics" has 11 letters, so there are 11 letters in the bowl. The probability of drawing the letter "O" is 1/11, since there is only 1 "O" in the 11 letters. Similarly, the probability of drawing the letter "B" is 1/11, and the probability of drawing the letter "J" is 1/11 as well.
Since the events of drawing the letter "O", "B", and "J" are independent of each other, the probability of drawing all three letters in order is the product of their individual probabilities.
Therefore, the probability of drawing "OBJ" from the bowl is (1/11) * (1/11) * (1/11) = 1/1331
It is a very low probability, the chances of drawing that sequence are very low.

What are a ratio and proportions?
A ratio is a way of comparing two or more values by division. A ratio expresses a relationship between two or more quantities. It is a comparison of one quantity to another. For example, the ratio of 3:2, 3 is being compared to 2.
A proportion is an equation that states that two ratios are equal. It can be written as:
a/b = c/d or a:b = c:d, where a,b,c,d are numerical values.
The ratio of tablespoons of vinegar to tablespoons of oil in the salad dressing is given by the ratio of the number of tablespoons of vinegar to the number of tablespoons of oil.
In this case, the ratio is 22 tablespoons of vinegar to 11 tablespoons of oil, or 22/11.
You can simplify this ratio by dividing both numerator and denominator by their greatest common divisor, that is 11
So the ratio of tablespoons of vinegar to tablespoons of oil is 2:1
Another way to express this is that for every 1 tablespoon of oil, 2 tablespoons of vinegar are needed.
So, If you want to know how many tablespoons of vinegar are needed for every tablespoon of oil you can use the proportion:
vinegar/oil = 22/11 = 2/1
Hence, you need 2 tablespoons of vinegar for every 1 tablespoon of oil.

Answer:
To find the resultant force of an object, we need to add up all the forces acting on it. The resultant force is the overall force that the object experiences, taking into account all the individual forces.
In this case, we are given four objects, A, B, C, and D, and the forces acting on them. To find the object with the largest resultant force, we need to calculate the resultant force for each object by adding up all the forces acting on it.
For object A, the forces acting on it are: 10 N, 10 N, and 10 N, for a total of 10 N + 10 N + 10 N = 30 N.
For object B, the forces acting on it are: 5 N, 5 N, 5 N, and 5 N, for a total of 5 N + 5 N + 5 N + 5 N = 20 N.
For object C, the forces acting on it are: 30 N and -5 N, for a total of 30 N + (-5 N) = 25 N.
For object D, the forces acting on it are: 10 N and -5 N, for a total of 10 N + (-5 N) = 5 N.
Therefore, the object with the largest resultant force is object C, with a resultant force of 25 N.

Marita purchased an item for 25% off the original price, plus an additional 20% off the
sale price. She also had a $10-off coupon, which the salesclerk applied after these two discounts. Marita's
final purchase price for the item was $30. Assuming she paid no sales tax, what was the original price of the
item Marita purchased?
Answer:
Marita had a $10-off coupon, so she paid $50 - $10 = $40 for the item
Step-by-step explanation:
To find the original price of the item, we need to work backwards through the discounts and find the price of the item before any discounts were applied.
We'll call the original price of the item "x."
First, we know that Marita received a 25% discount on the item, which means she paid 100% - 25% = 75% of the original price.
Then, Marita received an additional 20% discount on the sale price, which means she paid 100% - 20% = 80% of the 75% discounted price.
So, Marita paid 80% of the original price, which was reduced by a 25% discount. That means she paid 0.8 * 0.75 = 0.6 * original price = $30.
Therefore, the original price of the item was $30 / 0.6 = $<<30/0.6=50>>50.
Finally, Marita had a $10-off coupon, so she paid $50 - $10 = $40 for the item.
Which equation can be used to find B in the triangle below?
Right triangle A B C is shown. Side A B has a length of 6, side B C has a length of 10, and side A C has a length of 8.
The measure of angle B is 53°.
The equation used to find B is
B = [tex]sin^{-1}[/tex](4/5).
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
Right triangle ABC.
AB = 6
BC = 10
AC = 8
In order for the triangle to be a right triangle it must satisfy the Pythagorean theorem.
So,
BC² = AB² + AC²
100 = 6² + 8²
100 = 36 + 64
100 = 100
This means,
B

Now,
Sin B = 8/10 = 4/5
B = [tex]sin^{-1}[/tex] (4/5)
B = 53°
Sin C = 6/10 = 3/5
C = [tex]sin^{-1}[/tex] (3/5)
C = 37°
We see that,
∠A + ∠B + ∠C = 180
90 + 53 + 37 = 180

the point (3, 1) is located on a line with slope of 1/3. which point could also be located on the line?
The point (5,5/3) also lies on the line.
A point (x, y) is located on a line with slope m if and only if it satisfies the equation:
y = mx + b
where b is the y-intercept of the line. In this case, we know that the point (3, 1) is located on the line, so we can use the information to find the value of b and then write the equation of the line in slope-intercept form.
The y-coordinate of the point (3, 1) is 1, so we can substitute this into the equation and solve for b:
1 = (1/3) * 3 + b
This simplifies to:
1 = 1 + b
so, b = 0
So, the equation of the line is
y = 1/3 * x +0
Now we can use this equation to find the coordinates of any point that lies on the line. So any point (x, y) that satisfies this equation could also be located on the line.
For example, we can pick any x, calculate corresponding y.
x=5, y=5/3
