Answer:
[tex]4*10^5[/tex]
Step-by-step explanation:
So whenever sometimes says "how many is x larger than y", it just means what is x divided by y. For example 4 is 2 times as much as 2 because 4/2 = 2
With this being said we can simply divide two numbers
[tex]\frac{2*10^{12}}{5*10^6}[/tex]
Whenever you divide scientific notation you simply divide the two coefficients and subtract the exponents from the base 10
So: [tex]\frac{2*10^{12}}{5*10^6} =\frac{2}{5} * 10^{12-6}[/tex]
This gives you a result of: [tex]0.4 * 10^6[/tex]
Since we want the coefficient to be: [tex]1\le c < 10[/tex] we can take one of the 10s from the base, since 10^6 is just 6 tens being multiplied by each other and we can "borrow" one of them to get: [tex]0.4*10^6=0.4*10*10^5[/tex] which simplifies to: [tex]4*10^5[/tex]

The measure of the angles for the given parallel lines are-
∠1 = 100°∠2 = 80°∠3 = 100°What is defined as the term linear pair?Once two lines intersect at a single point, a linear pair of angles is formed. If the angles are adjacent to one another after the two lines intersect, they are referred to as linear. The sum of the angles of a linear pair always is 180°. These angles are also referred to as supplementary angles. The adjacent angles include those that share a vertex. As a result, the linear angles get a common vertex here as well.For the given question;
The set of parallel lines are given;
Thus,
∠1 + 80 = 180 (linear pair)
∠1 = 100°
Now, two set of parallel line form a parallelogram.
Thus, in parallelogram opposite angles are equal.
∠1 = °∠3 = 100°
So, ∠3 = 100°
And, ∠2 = 80° (opposite angle of 80)
Thus, the measure of the angles are calculated.

The measures of the internal angles of the triangle are given as follows:
Angle A: 55º.Angle B: 90º.Angle C: 35º.What is the sum of the internal angles of a triangle?
A triangle is composed by three internal angles, and the sum of it's measures is of 180º.
In the context of this problem, the measures are given as follows:
Angle A: 3x + 10.Angle B: 6x.Angle C: 2x + 5.Considering that the sum is of 180º, we can build an equation to solve for x as follows:
3x + 10 + 6x + 2x + 5 = 180
11x + 15 = 180
11x = 165
x = 165/11
x = 15
Hence the measures of the angles are given as follows:
Angle A: 3(15) + 10 = 55º.Angle B: 6(15) = 90º.Angle C: 2(15) + 5 = 35º.More can be learned about the sum of the internal angles of a triangle at https://brainly.com/question/25215131

The measure of the angles are;
m∠ A = 55 degreesm∠ B = 90 degreesm∠ C = 35 degreesHow to determine the value of each angleIt is important to note that the sum of angles in a triangle is supplementary.
Also, supplementary angles are defined as pair of angles that sum up to 180 degrees.
Two angles are termed supplementary when they add up to give 180 degrees.
Since, we have that the sum of the interior angles of a triangle are supplementary, then,
Angle A + Angle B + Angle C = 180 degrees
Given the values as;
m∠ A = 3x + 10m∠ B = 6xm∠ C = 2x + 5Now, put or substitute the values into the formula
3x + 10 + 6x + 2x + 5 = 180
collect like terms
3x + 6x + 2x = 180 - 15
Add or subtract like terms
11x = 165
Make 'x' the subject by dividing both sides by the coefficient of x, we have;
11x/11 = 165/11
Find the quotient
x = 15
But we have to find the angles by substituting the value of x
m∠ A = 3x + 10 = 3(15) + 10 = 55 degrees
m∠ B = 6x = 6(15) = 90 degrees
m∠ C = 2x + 5 = 2(15) + 5 = 35 degrees
Hence, the angles are 55 degrees, 90 degrees and 35 degrees respectively.

Please show work.
An infinite set is infinite from start to end, but both sides can have continuity, unlike a finite set, which has both start and end elements. The finite() function in R Language is used to determine whether or not the elements of a vector are Finite values. It returns a Boolean value for each vector element.
What exactly is a finite number?A countable number less than infinity that is the cardinality of a finite set - that is, some natural number, possibly zero. A genuine number, such as the result of a measurement (of time, length, area, etc.)In other words, it is a set that can be finished counting. 1,3,5,7, for example, is a finite set with four elements. The finite set element is a natural number, i.e. a non-negative integer. A set is infinite if it has an infinite number of elements; finite if the elements can be counted.In R, there are two kinds of infinity. Inf and -Inf represent positive and negative infinity, respectively, whereas NaN stands for 'Not a Number.'Hence, The finite() function in R Language is used to determine whether or not the elements of a vector are Finite values.

We have the relation:
y = 4x + 3
Since the slope (4) and the y-intercept (3) were already found, we need now to graph this line.
In order to do so, we can find two points belonging to this line and then draw a line that passes through those points.
The first point can be (0, 3), since we know that the y-intercept is 3, i.e., y = 3 for x = 0.
Now, to find a second point we can choose a value for x, let's say x = 1, and use it in the equation of the line to find the corresponding value of y:
y = 4x + 3 , x = 1
y = 4 * 1 + 3
y = 4 + 3
y = 7
So, (1, 7) is another point we can use.

The mean of the number of shoes according to the obtained results is; 8.49.
The median of the number of pairs of shoes obtained is; 9.
What is the mean and median of the frequency distribution?It follows from the complete task content that the mean and median of the data set are to be evaluated;
Since the mean is the average of all obtained data values, it follows from the mean formula;
Mean = Sum Total/Total Frequency
Mean = { ( 8 × 4 ) + ( 4 × 5 ) + .......+ (13 × 4) } / 65
Mean = 552/65
Mean = 8.49.
Also, the median of the set of 65 data values can be guessed to be the 33rd term.
On this note, the data value which corresponds to a cumulative frequency of 33 upon orderly arrangement is the median term.
Hence, since; 8 + 5 + 4 + 4 + 7 = 28; Hence, upon addition of 14, we have; 42.
Therefore, the median of the number of pairs of shoes is; 9 pairs of shoes.

Because she’s buying online, she must pay a shipping fee of $10. Josie wants to spend $150 or less. How many sets of dishes can Josie buy?
can be represented by equation:
35d + 10 = 150
subtract 10 from both sides:
35d + 10 - 10 = 150 - 10
35d = 140
divide both sides by 35:
35d/35 = 140/35
d = 4
Josie can by 4 dish sets.

Suppose that 15% of the time Danny goes swimming twice a week, 35% of the time he goes swimming once a week, and 50% of the time he doesn't go swimming at all in a given week. What is the expected value for the number of times Danny goes swimming during a week?
The expected value for the number of times Danny goes swimming during a week is 0.65.
Given that:-
Percentage of time Danny went swimming twice a week = 15 %
Percentage of time Danny went swimming once a week = 35 %
Percentage of time Danny doesn't go swimming at all in a given week = 50%
The expected value is calculated by multiplying each of the possible outcomes by the likelihood each outcome will occur and then summing all of those values.
Hence, based on the data given in the question, we can write,
Expected value n how many times Danny will go to swimming in a week = 15 %*2 + 35 % * 1 + 50 % *0 = 0.3 + 0.35 + 0 = 0.65

Una masa de 2,0 kg está unida al extremo de una cuerda de 5,0 m. La masa se mueve en una trayectoria circular sobre una superficie horizontal sin rozamiento. Si la resistencia a la rotura de la cuerda es 40 N, la máxima velocidad lineal con la que se puede hacer girar la masa sin que se rompa la cuerda es aproximadamente
La maxima velocidad lineal de la masa con la que se puede girar la masa es igual a 40 newtons.
¿Cuál es la velocidad lineal máxima permitida por la masa en movimiento circular uniforme?
En este problema tenemos el caso de una masa (m), en kilogramos, conectada a una cuerda y que experimenta un movimiento circular uniforme, en donde la partícula describe un movimiento a velocidad lineal constante (v), en metros por segundo, debido a una aceleración radial que está en la forma de tensión (T), en newtons, a través de la cuerda. En consecuencia, la velocidad máxima permitida es determinada a partir de las leyes de Newton:
T = m · (v² / R)
Donde:
m - Masa, en kilogramos.v - Velocidad lineal, en metros por segundo.R - Longitud de la cuerda, en metros.Si sabemos que m = 2 kg, R = 5 m y T = 40 N, entonces la maxima velocidad lineal permitida es:
40 N = (2 kg) · v² / (5 m)
v = 10 m / s
La maxima velocidad lineal permitida es igual a 10 metros por segundo.
