Answers

Answer 1

Answer:

The answer is 215=55x+40 or 215=40+55x

Step-by-step explanation:

The reason it is that is because the plumber charges $55 for a service and he adds 40 for each hour he works so that is why this is the answer Remember the total bill cost 215 so that comes as the equation is equal to.

Hope that helps

In the diagram below of triangle KLM, N is a midpoint of KL and P is a midpoint
of LM. If mZPNL = 2x + 61, and MKN = 97 - 7x, what is the measure of
ZPNL?

Answers

Answer:

Solution:

(1/12)^(-2b) * 12^(-2b+2) = 12

(12^-1)^(-2b) (12)^(-2b+2) = 12

(12^2b)(12)^(-2b+2) = 12

12^(2b-2b+2) = 12

12^2 = 12

144 does not equal 12

No solution.

Step-by-step explanation:

The measure of angle PNL will be equivalent to 69 degrees.

What is triangle?

A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically -

∠x + ∠y + ∠z = 180°

The sum of two sides of a triangle is greater then the third side. Mathematically -

a + b > c

There are different types of triangles such as -

equilateral triangle , scalene triangle , isosceles triangle etc.

Given is a triangle KLM such that N is a midpoint of KL and P is a midpoint of LM.

Triangles LMP and LKM are similar to each other. Therefore, PN will be parallel to MK. So angle PNL will be equal to angle MKN. Therefore -

2x + 61 = 97 - 7x

9x = 97 - 61

9x = 36

x = 4

So, angle PNL will be equal to -

2 x 4 + 61

69 degrees

Therefore, the measure of angle PNL will be equivalent to 69 degrees.

Find the distance between (-4,5) and (4,0) round to the nearest hundredth

Answers

Answer:

Solution: 9.43

Step-by-step explanation:

Remember that we can determine the distance between any two points using the distance formula, d = √(x₂ - x₁)² + (y₂ - y₁)². Let's substitute known values to determine the distance:

[tex]\mathrm{Compute\:the\:distance\:between\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2},}\\ \\\\\mathrm{d}= \sqrt{(4 - (-4))^2 + (0 - 5)^2} = \sqrt{(4 + 4)^2 + (- 5)^2} \\= \sqrt{(8)^2 + 25} = \sqrt{64 + 25} = \sqrt{89}[/tex]

Hence the distance between the points (-4,5) and (4,0) is exactly √89. The question asks us to round off to the nearest hundredth, so your solution will be approximated off to two digits → 9.43.

A cyclist rode 3.75 miles in 0.3 hours. How fast was she going in miles per hour? Round your answer to the tenths (first) decimal place.

Answers

Answer:

12.5 miles per hour

Step-by-step explanation:

The speed is the distance divided by time.

3.75 miles/0.3 hours= 12.5 miles per hour

Answer:

12.5 miles per hour

Step-by-step explanation:

To answer this question you have to make sure that the hours (denominator) equals to 1. To do this, divide 3.75 by 0.3, thus making the 0.3 hours into 1 hour. This results in 12.5 miles per hour, the correct answer. Hope this helped!

A text message plan costs $2 per month plus $0.23 per text. Fine the monthly cost for x text messages

Answers

Answer:

y= 2 + 0.23x

Step-by-step explanation:

Giving the following information:

A text message plan costs $2 per month plus $0.23 per text.

First, we need to structure the total cost formula:

y= total cost

x= number of text messages

y= 2 + 0.23x

Now, we can calculate the total cost for any number of text:

x= 200

y= 2 + 0.23*200

y= $48

x^2 - 4x - 3

Step-by-step explanation:

f(x) = x^2 - 6x

g(x) = -2x + 3

(f - g)(x) is the subtraction of the functions, f(x) - g(x)

You need to write it carefully using parentheses for function g(x).

(f - g)(x) = f(x) - g(x) =

= x^2 - 6x - (-2x + 3)

Now take care of the parentheses by distributing the negative sign to its left. It will change every sign inside the parentheses.

= x^2 - 6x + 2x - 3

What is the y-intercept of a function?

The intersection of the graph of the function with the y-axis gives the y-intercept of that function.

The y-intercept is the value of y on the y-axis at which the considered function intersects it.

Assume that we've got: y = f(x)

At y-axis, we've got x = 0, so putting it will give us the y-intercept.

Thus, y-intercept of y = f(x) is y = f(0)

The y-intercept is where a line crosses the y-axis, so this is the point where x = 0.

From the graph, we can see that the graph crosses the y-axis at (0,-3)

Hence, the correct answer is A (0,3).

The picture shows the Alamillo bridge in Seville, Spain. In the picture m<1=58 and m<2=24. Find the measure of the supplement of <1= and of <2. Someone please help!

Answers

Answer:

Supplement of <1 = 122°

Supplement of <2 = 156°

Step-by-step explanation:

Two pairs of angles are said to be supplementary, if their measures in degrees add up to give us 180°. A supplement of am angle is simply 180° - the measure of that angle.

Given that meadure of angle 1 = 58°, the supplement of angle 1 = 180° - 58° = 122°

Also, if the measure of angle 2 = 24°, the supplement of angle 2 = 180° - 24° = 156°.

Thus:

Supplement of <1 = 122°

Supplement of <2 = 156°

Step-by-step explanation:

If B lies on AC it makes the line segments AB and BC.

The value of BC is 2 which is the correct answer that would be an option (A).

What is a Line Segment?

A line segment is defined as a measured path between two places. Line segments can make up any polygon's sides because they have a set length.

The figure given below shows a line segment AC , where the length of line segment AC refers to the distance between its endpoints, A and C.

Point B lies on AC between A and C.

A______________B______________C

Given that B lies on AC it makes the line segments AB and BC.

AB = 8 and AC = 10

⇒ AB + BC = AC

⇒ AB + BC = 10

⇒ 8 + BC = 10

⇒ BC = 2

Therefore, the value of BC is 2 which is the correct answer that would be an option (A).
