Answer 1
10x-6-10x-2
10x-8-10x
= -8
Answer 2

Answer:

Step-by-step explanation:

1) group any number with an X together and rewrite answer (if there is a negative in front of a number always carry it with it when rearranging.)

10x-10x-6-2

2) lets solve the numbers with Xs together

10x+10x= 20x

3) now lets solve whole numbers

-6-2=-8

4) bring down the 20x and the -8/ rewrite problem with your solved numbers

20x-8

5) we have to have X alone so in order to get rid of the 20 in front of the X you must divide 20 by 20x,

20x/20 ( it cancel's out and now you're left with X)

X=-8

6) but whatever you do to one side of the equal sign you have to do to the other side so now you must divide -8/20 which will leave you with

Answer: X=-0.4 or -2/5

What is the vertex form of y equals 2 x squared minus 8 x plus 1?

Answers

According to the given information, the vertex form is 2(x - 8)² + 1.

What do we mean by vertex form?A quadratic function has the vertex form f(x) = a(x - h)2 + k, where a, h, and k are constants. A vertex form in geometry is a location where two or more curves, lines, or edges converge. As a result of this definition, vertices are the intersection of two lines that create an angle as well as the corners of polygons and polyhedra. The four corners of a square, for instance, are each referred to as a vertex.

So, vertex form:

Vertex form: f(x) = a(x - h)² + k

Now, substitute the given values as:

2(x - 8)² + 1

Answers

The coordinates of the point P is P(x, y) = (1, - 26 / 7). (Correct choice: C)

How to calculate a resultant point's coordinates using the weighted averages method?

We must locate the third point by applying a method based on a weight average-like formula after finding the coordinates of two points on the Cartesian plane:

P(x, y) = (2 / 7) * A(x, y) + (5 / 7) * B(x, y)

P(x, y) = (2 / 7) * (- 4, 2) + (5 / 7) * (3, - 6)

P(x, y) = (- 8 / 7, 4 / 7) + (15 / 7, - 30 / 7)

P(x, y) = ( 7 / 7, - 26 / 7)

P(x, y) = ( 1, - 26 / 7)

Calculate the percent of each type of snake. Use the percent that you find and multiply each times 360° to
find the number of degrees for each sector.

I need help solving the percent and degree

Answers

Percent of vipers is 20% and its degree is 72 degrees.

Percent of colubrids is 46% and its degree is 165.60 degrees.

Percent of elapids is 18% and its degree is 64.80 degrees.

Percent of giant snakes is 16% and its degree is 57.60 degrees.

How we do calculate the percent and degree?

The percent can be calculated as follows:

Percent of vipers = (Number of vipers / Total number of snakes) * 100 = (10 / 50) * 100 = 0.20 * 100 = 20%

Percent of colubrids = (Number of colubrids / Total number of snakes) * 100 = (23 / 50) * 100 = 0.46 * 100 = 46%

Percent of elapids = (Number of elapids / Total number of snakes) * 100 = (9 / 50) * 100 = 0.18 * 100 = 18%

Percent of giant snakes = (Number of giant snakes / Total number of snakes) * 100 = (8 / 50) * 100 = 0.16 * 100 = 16%

The degrees can be calculated as follows:

Degree of vipers = Percent of vipers * 360 = 20% * 360 = 72 degree

Degree of colubrids = Percent of colubrids * 360 = 46% * 360 = 165.60 degree

Degree of elapids = Percent of elapids* 360 = 18% * 360 = 64.80 degree

Help me solve this problem please.

Answers

Answer:

  C.  1889

Step-by-step explanation:

Given fixed weekly costs of $3778 and a variable cost per handle of $1, you want to know how many handles must be produced weekly for sale at $3 each to break even.

Contribution margin

The "contribution margin" of each handle is the difference between its variable cost and its selling price:

  $3 -1 = $2

Break even

The enterprise will break even when the sum of contribution margins is equal to the fixed costs. If h is the number of handles produced and sold, then to break even, we must have ...

  2h = 3778

  h = 1889

1889 handles must be molded weekly to break even.

__

Additional comment

You get the same result if you write the profit equation and solve for the number of handles that makes profit be zero.

  profit = revenue -cost

  0 = (3h) -(3778 +1h)

  3778 = 2h . . . . . as above

  1889 = h

The mural in the art gallery is 7 meters tall. It's 69 centimeters taller than the marble sculpture. How tall is the sculpture?

Answers

Mural Height = 7 meters

Find the height of the marble sculpture if the mural is 69 centimeters taller.

Solution:

Convert the height of the mural into centimeters to easily calculate how tall it is from the marble sculpture.

1 meter = 100 cm

7 meters = 700 cm

Subtract 69 cm from 700 cm in order to get the height of the marble sculpture.

700cm - 69 cm = 631 cm

Convert 631 cm into meters by dividing it with 100.

=631 /100

subtract ax from both sides

Answers

The total amount payable at the end of 4 years is 406

In this given sum we are provided with the values of principal , rate of interest , and the number of years , we are asked to calculate the amount payable after 4 years that is the matured amount which is calculated with the addition of the principal amount and the simple interest. For that we had to first find out the amount of interest and then we need to add that with the principal amount to get the matured amount or the amount that is payable at the end of 4 years.

here we have to apply the formulla of simmple interest :

(principal × rate of interest × no. of years )/ 100

In the given sum principal (p) = 350 , rate of interest (r) = 4% pa , no. of years (n) = 4

Its name comes from the shape of the tool. It is one fourth of a whole circle, and quad means four. When this tool was originally built, it had many purposes. First, astronomers used it to determine the height of stars above the horizon. Second, land surveyors used it to measure the height of manmade creations like buildings and landforms such as mountains. Third, soldiers used the quadrant to aim weapons with accuracy.As years passed, sailors found use for the quadrant, too. By the 16th century, sailors needed a better way to navigate their ships. In the past, they used key landmarks to find their positions. However, when exploring new lands, they had to travel through waters that were unfamiliar to them. Another challenge they faced was that at times, they were surrounded by only water and had no landmarks to follow. Luckily, many sailors understood the movement of the Pole Star, called Polaris. It moved very little because of its location above the North Pole. The height of Polaris changed depending on a ship's latitude. Latitude is the distance north or south of the equator. Knowing how high Polaris was in relation to their ship could help sailors navigate the waters, quickly and with ease.To find the height of the star, sailors used the quadrant, the first latitude-measuring tool. For sailors, the quadrant was a simple tool made from wood or metal. Due to its simplicity, sailors learned quickly how to use the instrument. First, they would line the sights of the quadrant up with Polaris. Using the tool, they could measure the angle between the horizon and Polaris to determine their latitude. To do this, they looked at the recordings of the degrees along the arc of the tool. The quadrant remained one of the most common navigational tools used by sailors for a long time. It used a combination of astronomy and math to lead them successfully to the New World.quadrantSelect the best evidence to support the inference that the quadrant and Polaris helped sailors navigate unknown waters.Group of answer choicesTo do this, they looked at the recordings of the degrees along the arc of the tool.Luckily, many sailors understood the movement of the Pole Star, called Polaris.A combination of astronomy and math to lead them successfully to the New World.When exploring new lands, they would be traveling through unfamiliar waters.
