Step-by-step explanation:

Explanation:

Place the decimal point between the first two digits to get 5.0

Then we must move the decimal point 4 spots to the right to get back to 50,000

So that's where the "4" comes in with the 10^4

This means 50,000 = 5 * 10^4 which is in scientific notation.

The answer in scientific notation is 5 times 10^4

The exponent of four tells you to multiply 10 by itself 4 times.

10 x 10 = 100 x 10 = 1000 x 10 = 10000

And 10000 times 5 is equal to 50,000.

Step-by-step explanation:

Capitals represents countries as the function

The equation of a line perpendicular to the line is y = (-1/2)x - 9

Slope of the line perpendicular to y = 2x - 1, m =-1/2;

Therefore, equation of line perpendicular to given line in slope- intercept form is; y = (-1/2) x + c;

This line passes through (-8, -5); therefore;

-5 = (-1/2)(-8) + c;

c = -9;

Therefore, equation of required line is y = (-1/2)x - 9;

Perpendicular lines are two non-vertical lines in the same plane that intersect at a right angle. Horizontal and vertical lines are perpendicular to one other, forming the coordinate plane's axes. Negative reciprocals are the slopes of two perpendicular lines.

Vertical and horizontal lines are parallel to each other. In this scenario, the slope of the perpendicular line is equal to the slope of a horizontal line, which is 0. The slope of the parallel line is 0 while the slope of the perpendicular line is unknown.

If a high school student decides to apply four of six famous colleges, then the four colleges can be selected in as many as 15 different combinations.

As per question statement, a high school student decides to apply four of six famous colleges.

We are required to calculate the number of combinations in which the four colleges can be selected.

To solve this question, we need to know the formula of Combination which goes as [tex](nCr)=\frac{n!}{r!(n-r)!}[/tex]

, i.e., we are to select a set or "r" from a set of "n".

Here, we have to select a combination of 4 from a set of 6.

Therefore applying (nCr) formula with (n = 6) and (r = 4), we get,

[tex](6C4)=\frac{6!}{4!(6-4)!} =\frac{6!}{4!2!}=\frac{4!*5*6}{4!*2}=\frac{5*6}{2}=(5*3)=15[/tex].

By solving a system of equations we can conclude that ross has a total of $200 in $5-notes.

Let's define the variables:

We know that there are 15 more $2-notes than $5-notes, then:

y = x + 15

And the total amount of $5-notes is $90 more than the total amount of $2-notes.

x*5 = 90 + y*2

Then we have a system of equations:

y = x + 15

x*5 = 90 + y*2

Replacing the first equation into the second one we get:

x*5 = 90 + (x + 15)*2

Now we can solve this for x:

x*5 = 90  + x*2 + 30

5*x - x*2 = 90 + 30

3*x = 120

x = 120/3 = 40

x = 40

In this way, we conclude that Ross has 40 of the $5-notes, then the total value is:

40*$5 = $200

Answer:

24

Step-by-step explanation:

First, we know the total number of students: 135

Then we can see that 22+31+28 students like two flavours: 81

Then we can see how many students like all three flavours: 15

Because the students who like two flavours are counted twice, we need to subtract them once.

Because the students who like three flavours are counted three times, we need to subtract them twice.

So we get 135-81-15*2

135-81-30

24

24 students do not like any of the given flavours

if this was helpful pls give me brainliest <3

Answer: 24 students dislike any of the flavors

Step-by-step explanation:

Soo since you have the diagram without any error it the other question soo at the start of the question they have told that in total there are 135 students.

so at the all the number of students with the different types of flavors then you will get the total amount of students who like 2 kinds of flavors and all three flavors.

31+22+28+15+15= 111 students  (since the students who like three flavors are counted three times, we need to subtract them twice, I add it here to make it easier *15+15*)

so next you should subtract that amount from the total amount of students  who likes multiple flavors in order to get the number of students who dislikes and of the flavors.

135-111= 24 students dislike any of the flavors

In the garage 33.33 percentage of work were MOTS.

Percentage is defined as per-cent, that is out of hundred. The percentage is calculated by dividing the acquired value by the total value and multiplying the result by 100.

Now in the given problem,

Total number of vehicles on which Keith worked is 105.

The number of MOTS among the 105 is 35.

Now we have to calculate the percentage of the MOTS out of a total 105 vehicles.

Let us use the formula=(number of MOTS ÷ total vehicles)×100

Therefore required percentage=[tex]\frac{35}{105}\times 100\%[/tex]

or, percentage=33.333...%

Therefore we can conclude that the total percentage of MOTS were approximately 33.33%(rounded to 2 decimal places).

Answer:

The third graph

Step-by-step explanation:

We can immediately eliminate the 1st and last graphs because they are decreasing, not increasing. It wouldn't make sense that the more classrooms there are, the fewer students. Y = 22x would be increasing in the graph.

Let's plug some x values into the equation first, to see where our points are at.

Plug 1 into x

Y = 22(1)

Y= 22

(1,22)

Plug 2 into x

Y = 22(2)

Y = 44

(2,44)

Plug 3 into x

Y = 22(3)

Y = 66

(3,66)

Plug 4 into x

Y = 22(4)

Y = 88

The second graph matches the coordinates, so it works, but it isn't a complete function graph. A function graph needs a line drawn through the points. The second graph isn't your answer.

Let's look at the third graph. The coordinates also match up with the graph and it has a line drawn through the points. It's an accurate function graph representing this scenario. Therefore, the third graph is your answer.

Answer: the 2nd graph is what i got right on the test

Step-by-step explanation:

The solutions to the given equation are x = -1, x = 0 and x = 3

From the question, we are to determine the solution of the given equation.

The given equation is

x³ -2x² -3x = 0

The graph of the function y = x³ -2x² -3x is shown below

The solutions of the equation x³ -2x² -3x = 0 are the values where the graph cuts the x-axis

From the graph, we can observe that

The curve cuts the x-axis at x = -1, x = 0 and x = 3

Hence, the solutions to the given equation are x = -1, x = 0 and x = 3

Testing the solutions

For x = -1

x³ -2x² -3x = 0

(-1)³ -2(-1)² -3(-1) = 0

-1 -2(1) +3 = 0

-1 -2+3 = 0

-3+3 = 0

0 = 0

For x = 0

x³ -2x² -3x = 0

(0)³ -2(0)² -3(0) = 0

0 - 0 - 0 =0

0 = 0

For x = 3

x³ -2x² -3x = 0

(3)³ -2(3)² -3(3) = 0

27 -2(9) - 9 = 0

27 -18 - 9 = 0

0 = 0

Since, all the statements are true, then values are solutions of the equation.

From the question, we are to determine the factor by which 1.143 × 10¹ is larger than 9 × 10⁻¹

To determine how many times larger the number is, we will divide 1.143 × 10¹ by 9 × 10⁻¹

Carrying out the division operation

(1.143 × 10¹) ÷ (9 × 10⁻¹)

= (1.143 ÷ 9) × (10¹ ÷ 10⁻¹)

= (1.143 ÷ 9) × (10¹ ÷ 10⁻¹)

= 0.127 × (10¹ ⁻ ⁽⁻¹⁾)

= 0.127 × (10¹ ⁺ ¹)

= 0.127 × (10²)

= 0.127 × 10²

Columnar addition

Answer:

This article is about the basic inequality {\displaystyle z\leq x+y}{\displaystyle z\leq x+y}. For other inequalities associated with triangles, see List of triangle inequalities.

Three examples of the triangle inequality for triangles with sides of lengths x, y, z. The top example shows a case where z is much less than the sum x + y of the other two sides, and the bottom example shows a case where the side z is only slightly less than x + y.

In mathematics, the triangle inequality states that for any triangle, the sum of the lengths of any two sides must be greater than or equal to the length of the remaining side.[1][2] This statement permits the inclusion of degenerate triangles, but some authors, especially those writing about elementary geometry, will exclude this possibility, thus leaving out the possibility of equality.[3] If x, y, and z are the lengths of the sides of the triangle, with no side being greater than z, then the triangle inequality states that

{\displaystyle z\leq x+y,}z\leq x+y,

with equality only in the degenerate case of a triangle with zero area. In Euclidean geometry and some other geometries, the triangle inequality is a theorem about distances, and it is written using vectors and vector lengths (norms):

{\displaystyle \|\mathbf {x} +\mathbf {y} \|\leq \|\mathbf {x} \|+\|\mathbf {y} \|,}\|\mathbf {x} +\mathbf {y} \|\leq \|\mathbf {x} \|+\|\mathbf {y} \|,

John has 7 five-dollar bills, 5 ten-dollar bills and 3 twenty-dollar bills.

Total number of bills with John = 15

Total money with John = $145

John has a mix of $5, $10 and $20 bills

Let the number of $5 bills be x, $10 bills are y and $20 bills be z

Formulating the equations:

5x + 10y + 20z = 145-------(1)

x + y + z = 15--------(2)

As per the question, the number of ten dollar bills is one less than twice the number of twenty dollar bills:

y = 2z - 1

Putting y = 2z-1 in equating (1) and (2) we get:

5x + 10(2z-1) + 20z = 145

5x + 20z - 10 + 20z = 145

5x + 40z = 155--------(3)

x + y + z = 15

x + 2z - 1 + z = 15

x + 3z = 16--------(4)

Multiplying equation (4) with 5 and using Gaussian Elimination to equate (3) and (4)

5x + 40z = 155

5x + 15z = 80

25z = 75

z = 3

Putting z=3 in (4) we get

x = 7 and y = 5

So, John has 7 five-dollar bills, 5 ten-dollar bills and 3 twenty-dollar bills.
