2x 5x+6 please simplify ​

we know that

The side splitter theorem states that if a line is parallel to a side of a triangle and the line intersects the other two sides, then this line divides those two sides proportionally

so

18/6=DC/11

solve for DC

DC=3*11

DC=33

Find the length of BD

BD=BC+DC

BD=11+33=44 units

therefore

the answer is 44 units

Answer: i think B

Step-by-step explanation:

im not that sure tho

2r + 7 = 4r - 13

subtract 4 from both-side of the equation

2r - 4r + 7 = 4r - 4r - 13

-2r + 7 = -13

subtract 7 from both-side of the equation

-2r + 7 = -13 - 7

-2r = -20

divide both-side of the equation by -2

r = 10

Let the number of miles I can travel for $33 be x;

The total cost of taxi ride from the airport is;

Flat fee + Tolls fee + Charge/Mile = Total cost

Flat fee = $2.00

Toll fee = $3.50

Charge per mile = 0.50x

Total cost = $33.00

Thus, we have;

Thus, the number of miles

Answer:

Explanation:

From the information given, 3

For this exercise you need to use the following formula:

Where θ is the Central angle in radians, "S" is the arc length and "r" is the radius of the circle.

In this case, you can identify that:

Knowing these values, you can substitute them into the formula and then evaluate, in order to find the measure of the Central angle in radians. This is:

The answer is:

Answer: KM = 18

Step-by-step explanation:

K---------------L---M

         15        +  3 = 18

step 1

Find the slope m

we need two points

so

(200,100) and (80,220)

m=(220-100)/(80-200)

m=120/-20

m=-6

step 2

Find the equation of the line in point slope form

y-y1=m(x-x1)

we have

m=-6

(x1,y1)=(200,100)

substitute

y-100=-6(x-200)

Convert to slope intercept form

y-100=-6x+1200

step 3

Find the equation in standard form

Ax+By=C

where

A is a positive integer

B and C are integers

so

y=-6x+1300

Since angles ACB and ECD are vertical angles, they are congruent, so we have

Calculating the sum of internal angles in triangle ABC, we have:

Since triangles ACB and DCE are congruent, we have [tex]\begin{gathered} DEC=ABC \\ 5x=65 \\ x=13 \end{gathered}[/tex]

we have the exponential decay function

Part b

Estimate the population of the country in 2018

Remember that

t=0 -----> year 1995

so

t=2018-1995=23 years

substitute in the function above

Part c

After how many years will the population of the country be 2 ​million, according to this​ model?

For P(t)=2

substitute

Solve for t

Apply ln on both sides

t=229 years

Solution:

Let t be the number of hours Mai works as a tutor.

Given that She earns $12 a hour as a tutor, this implies that for t number of hours, she will earn

For the month, she worked a combined total of 85 hours. This implies that

Her total eranings for the month is expressed as

Recall that she earnes $7 an hour while working as a waitress.

Thus, we have her combined total amount in dollars expressed as

Hence, the expression is

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data

s = 50in

d = 20in

surface area of a cone = ?

Step 02:

surface area of a cone

SA = πr² + πrs

r = d/2 = 20in / 2 = 10in

SA = 3.14*(10in)² + 3.14*50in*10in

SA = 314in² + 1570in²

SA = 1884in²

The answer is:

SA = 1884in²

To find the angle measure "n", we proceed as follows:

Step 1: Recall that the sum of angles at a point is 360 degrees, as below:

Therefore, the meas

The bar graph is attached below.

The heights of the rectangular bars in a bar graph, which displays complete data, are proportionate to the values they indicate. The graph's bars can be displayed either vertically or horizontally. Bar graphs, commonly referred to as bar charts, are a visual depiction of groups of data. It is one method of processing data. A bar graph is a great tool for representing data that are unrelated to one another and do not need to be displayed in any particular sequence. The bars provide a visual representation for comparing amounts in several categories. The x and y axes, commonly known as the horizontal and vertical axes, the title, labels, and a bar graph are all included.

Hence we frame the desired bar graph.

Answer:

To find the perimeter of the triangle, you would add p + m + n. To find the area of the triangle you would use (p x m) /2. To find a missing side of the triangle, given that it is a right triangle, you would use p^2 + m^2 = n^2

First, we need to find the sides of the triangle.

The base of the triangles is 8ft - 5ft = 3ft.

The height for the triangle is 7ft - 4ft = 3ft

Now, we need to find the area of the triangle:

Replacing the values:

Then

Now, we need to find the area for the rectangle:

Area for a rectangle = Length * Width

In this case:

Length = 8ft

Width = 7ft

Therefore:

Then

Finally, to find the area of the shaded region we need to subtract the triangle area from the rectangle area:

Therefore:

Hence, the area for the shaded region is 51.5 ft².

Area of the triangle is 225 sq. cm.

Given:

The base of the triangle is, b = 30cm.

The height of the triangle is, h = 15cm.

The objective is to find the area of the triangle.

The formula to find the area of the triangle is,

Now, substitute the given values in the above formula.

Hence, the area of the triangle is 225 sq. cm.

Answer:

3056 can be be formed as the smallest four digit number

In order to solve the equation for y, we just need to isolate the variable y in one side of the equation. So we have:

So the answer is y = 4 - 1/3 x

If one line passes through the points (x₁, y₁) and (x₂, y), the slope of the line can be calculated using the formula:

Additionally, the equation can be expressed in point-slope form as:

From the problem, we identify:

Then, we calculate the slope of the line using (1):

Finally, we find the equation of the line using (2):

The absolute value gives always a positive number.

If a is negative, then a|x| is negative and |ax| is positive.

Therefore, the graph of y=a|x| won't be the same as the graph of y=|ax|.

Another way to see it, is by using the property:

Since a is negative, then |a| = -a. So, |ax| = -a|x|, which is clearly different from a|x|.

Okay, here we have this:

Considering the provided information, that in a rhombus opposite angles are equal, and that the sum of the angles of a triangle is 360 °, we obtain:

360°=100°+100°+4(m∠DBC)

Now, let's clear "m∠DBC":

360°=200°+4(m∠DBC)

4(m∠DBC)=360°-200°

4(m∠DBC)=160°

m∠DBC=160°/4

m∠DBC=40°

Finally we obtain that the correct answer is the option A.

Hello there. To answer this question, we need to plug in the value given by the question and solve for C, the temperature in Celsius.

We want to find the equivalent temperature in Celsius to 14 degrees Fahrenheit.

Knowing that F = 9/5C + 32, making F = 14 lead us to:

14 = 9/5C + 32

Subtract 32 on both sides of the equation

9/5C = -18

Multiply both sides of the equation by a factor of 5/9, in order to get:

C = 5/9 (-18) = -10.

This is the equivalent temperature we were looking for.
