Solve for x. The triangles in each pair are similar.
Answers
Step-by-step explanation:
similar triangles means that all angles in one triangle are exactly the same as the angles in the other triangle.
and the lengths of all sides of one triangle have the same scaling factor with the lengths of the sides of the other triangle.
so, when we compare the "features" of the triangles, we see that C corresponds to S, B to R and D to T.
so, DC (50) corresponds to TS (70).
and that means that CB (60) corresponds to SR (11x - 4).
the scaling factor from BCD to RST is 70/50 = 7/5.
that means DC × 7/5 = TS.
and CB × 7/5 = SR :
60 × 7/5 = 11x - 4
12 × 7 = 11x - 4
84 = 11x - 4
88 = 11x
x = 8

Find the difference ("subtract") between (x+7) & (3x+4)
Answers
After subtraction (3x+4) - (x+7), the resultant answer is 2x-3.
What is subtraction?One of the four operations used in mathematics, along with addition, multiplication, and division, is subtraction.
Removal of items from a collection is represented by the operation of subtraction.
For instance, in the following image, there are 5 2 peaches, which means that 5 peaches have had 2 removed, leaving a total of 3 peaches.
So, we have:
(x+7) and (3x+4)
We have to subtract as:
(3x+4) - (x+7)
Now, subtract as follows:
(3x+4) - (x+7)
3x+4 - x-7
2x-3
Therefore, after subtraction (3x+4) - (x+7), the resultant answer is 2x-3.

What is $340.372545 rounded to 2 significant decimal figures? a. $340.36 b. $340.372 c. $ 340.35 d. $ 340.37 e. $ 340.373
Answers
When rounding $340.372545 to 2 significant decimal figures, the correct answer is (d) $340.37.
To round $340.372545 to 2 significant decimal figures, we look at the third digit after the decimal point. Since the digit is 2, which is less than 5, we leave the second decimal figure unchanged. The correct rounding rule is to round down if the third digit is less than 5.
Therefore, the answer is $340.37 (option d). This rounds the number to two significant decimal figures, preserving the accuracy of the original number up to that point. The other options do not follow the rounding rule correctly and would result in either truncation or incorrect rounding.

Answers
The number of books published by a small publishing company is 3240.
Given that, a small publishing company is planning to publish a new book. The production costs will include one-time fixed costs and variable costs.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Let the number of books be x.
With one method, the one-time fixed costs will total $44,714, and the variable costs will be $11.50 per book.
That is, 44,714+11.50x
With the other method, the one-time fixed costs will total $17,174, and the variable costs will be $20 per book.
That is, 17,174+20x
Now, the number of books produced will the costs from the two methods be the same.
So, 44,714+11.50x=17,174+20x
⇒ 44,714-17,174=20x-11.50x
⇒ 8.5x = 27540
⇒ x=3,240
Therefore, the number of books published by a small publishing company is 3240.

If the sample has the same mix of people, in the same proportions, as the population being studied then sociologists know if the sample they are using is representative. So the option c is correct.
No subject is off-limits when sociologists use the sociological lens and start asking questions. Every facet of human behaviour has the potential to be studied. Sociologists cast doubt on the society that people have built and inhabit. They observe behavioral patterns as individuals navigate that world.
Sociologists have uncovered workplace patterns that have revolutionized industries, family patterns that have educated parents, and educational patterns that have supported structural changes in classrooms by using sociological methodologies, methodical research, and a scholarly interpretive approach.

Martha's family set a goal to earn $7,507.50 in interest in account 2. How long will it take them to meet this goal?
Answers
It will take them to meet this goal 10.01 years (or approximately 10 years and 1 month)
To solve this problem, we'll need to use a formula:
Simple interest = Principal × rate × time (in years)
We can rearrange the formula as follows:
Time (in years) = Simple interest / (Principal × rate)
As per the formula, to calculate the time it will take the family to earn the interest, we'll need to know the principal and the rate. These values are not given in the question, so we'll assume that the principal is $10,000 and the interest rate is 7.5 percent (or 0.075 as a decimal).
Simple interest = Principal × rate × time (in years)
$7,507.50 = $10,000 × 0.075 × time (in years)
Divide both sides by $10,000 × 0.075 to isolate the time (in years):
time (in years) = $7,507.50 / ($10,000 × 0.075)
time (in years) = 10.01 years
So, it will take the family 10.01 years (or approximately 10 years and 1 month) to earn $7,507.50 in interest in account 2.

Let A={(x-3)/(x-2)ЄR : X<0}
be a subset of real numbers.
i) Define A's supremum and infimum.
Answers
The supremum of the set A does not exist (it is negative infinity), and the infimum of the set A is 1.
To define the supremum and infimum of the set A, we first need to determine the properties of the set.
The set A is defined as A = {(x-3)/(x-2) ∈ R : x < 0}.
To find the supremum (also known as the least upper bound) of A, we need to find the smallest value that is greater than or equal to all the elements of A. In other words, we are looking for the least upper bound of the set A.
Let's analyze the elements of A:
For x < 0, the expression (x-3)/(x-2) can take on different values depending on the value of x. We need to find the maximum value that this expression can reach for all x < 0.
As x approaches 0 from the left side, (x-3)/(x-2) approaches negative infinity. Therefore, there is no finite supremum for the set A.
Next, let's find the infimum (also known as the greatest lower bound) of A. We need to find the largest value that is less than or equal to all the elements of A. In other words, we are looking for the greatest lower bound of the set A.
Again, analyzing the elements of A:
As x approaches negative infinity, (x-3)/(x-2) approaches 1. Therefore, the infimum of the set A is 1.

during the exponential phase, e. coli bacteria in a culture increase in number at a rate proportional to the current population. if the population doubles in 20.4 minutes, in how many minutes will the population triple
Answers
The time required for the population to triple is 7.68 hours. the correct answer is 7.68 hours.
During the exponential phase, the rate of growth of a bacterial population is proportional to the size of the population. If the population doubles in 20.4 minutes, it means that the population is growing at a rate such that it doubles after every 20.4 minutes or every 1.36 hours.
This is because 60/20.4 = 2.94 cycles occur in an hour and 1 cycle corresponds to a doubling of the population. This growth rate can be quantified using the concept of generation time, which is the time taken for the population to double.
Thus, if the population doubles every 1.36 hours, the generation time is 1.36/ln2 = 1.92 hours.
In order to calculate the time required for the population to triple, we need to find out how many generations it takes to achieve this.
Since the population doubles once every 1.36 hours, it will take two generations to double twice or 2 x 1.92 = 3.84 hours for the population to double twice.
Similarly, it will take four generations or 4 x 1.92 = 7.68 hours for the population to double three times.
Thus, the time required for the population to triple is 7.68 hours.

What can you see in this form of the linear equation? 6x+2y=13
Answers
The given equation 6x+2y=13 is a linear equation in two variables. In this equation, x and y are variables while 6 and 2 are their respective coefficients, and 13 is a constant term. The equation can be represented as a straight line on a graph. The slope of this line is -3, and it intersects the y-axis at the point (0, 13/2).
In this equation, if we substitute x=0, then y=13/2, and if we substitute y=0, then x=13/6. These are the two points that the line passes through the x and y-axis.
A linear equation is a polynomial equation that is of the first degree, meaning the variables in the equation are not raised to any powers other than one. This equation is in the standard form where the variables are in the first degree. 6x + 2y = 13 is the form of the given linear equation. x and y are the two variables, and 6 and 2 are their respective coefficients. The equation can be represented as a straight line on a graph. The slope-intercept form of this equation is y = -3x + 13/2. The equation is also in standard form.
When x = 0, the equation becomes 2y = 13. This means that the point of intersection is (0, 13/2) when y = 0, the equation becomes 6x = 13, and the point of intersection is (13/6, 0). The slope of the line is -3. When x increases by 1, y decreases by 3.
