Write and solve an equation to find the value of x.
Answer:
x = 60
Step-by-step explanation:
Let the two opposite angles be equal and let's call them y.
Because of the theory of angles on a straight line 120 +y = 180
y = 60
Because of the theory of angles on a straight line 2x + y = 180
2x + 60 = 180
2x = 120
x = 60
Alternatively. (also a lot easier)
120 and 2x are opposite angles so they are equal and so;
2x = 120
x = 60

There are two numbers such that one of the numbers is 5 2/7 more than twice the other number. If you multiply the smaller number by 5, the product is twice the larger number. What are the two number? Please no links and answer fast!
Answer:
Smaller number: 10 4/7
Bigger number: 26 3/7
Step-by-step explanation:
How I did this problem was very simple, so first I made my different numbers, the smaller number being x, and the larger number being
2x+5 2/7. Then, I did the equation 5x=4x+ 74/7. How I got this equation was I multiplied 5 2/7 into 2 and got 74/7. After the equation, I got my answers, then double checked them.

Solve x to the nearest tenth
Answer:
12.5
Step-by-step explanation:
We see in the other triangle that the ratios is 2:5 (4 to 10).
Therefore, assuming they are similar, we can assume the ratio is the same for the missing triangle.
So,
10/4 = 2.5
5(given) x2.5 = 12.5
Answer:
7.7
Step-by-step explanation:
10² - 4² = 84
√84 = 9.16 so 9.2
now we now have the hypotenuse of the other triangle
9.2² - 5² =59.64
√ 59.64 = 7.72 so 7.7
How do you find the horizontal asymptote and Y intercept?
The process of finding the horizontal asymptote and y intercept is explained below.
In order to find the steps, we must know that what is meant by asymptote and intercept.
The process of finding the asymptote is defined as the horizontal asymptote of a rational function can be determined by looking at the degrees of the numerator and denominator.
If the degree of numerator is less than degree of denominator then horizontal asymptote at y = 0
Where as if the degree of numerator is greater than degree of denominator by one then there is no horizontal asymptote
Finally if the degree of numerator is equal to degree of denominator then the horizontal asymptote at ratio of leading coefficients.
As per the definition of intercept we have identified that the point that will intersect at the y axis is referred as the y intercept.

Therefore , the answer to the above problem is 5.75 for the mean and 9 for the median.
What is mean?Regardless of whether many elements are discrete or continuous, averages can only be calculated for numeric variables. You may find this by dividing the amount of values present in the dataset by its total number of values in the data. It is possible to perform computations using either raw data or data that has been compiled into frequency tables. The average value in mathematics is obtained by adding up all the integers in a data set and dividing the total by the total number of numbers. For example, in the data below
Here,
Spread it all out here first:
4, 5, 6, 7, 7, 8, 9, 9, 9, 9, 9, 10, 10, 10, 10, 10
The mean is calculated by dividing total total by the total number of scores. Add up each number.
There are 16 numbers total, and they add up to 92. 92 / 16 = 5.75
To get the median, identify the middle number among all the other numbers.
Sadly, there is no "center number" given that there are 16.
Add the ninth and eighth numbers together, then divide by to find the middle.

A company makes chocolate candies in the shape of a solid sphere. Each piece of candy has a diameter of 6cm. If a box contains 15 pieces of candy, how much chocolate does the box contain? Use 3. 14 for π, and do not round your answer
The total amount of solid sphere chocolate in the box is 1695.6 cubic centimeters.
What is volume?The space occupied within an object's borders in three dimensions is referred to as its volume.
What is the volume of sphere?The volume or the space inside the borders of the sphere is given by the formula:
[tex]V = \frac{4\pi r^3}{3}[/tex]
Given that the diameter is 6cm, the radius r = 3cm.
Substituting the value of radius in volume we have:
[tex]V = \frac{4 (3.14)(3)^3}{3}[/tex]
[tex]V= 113.04[/tex]
The box contains 15 candies hence the total volume will be:
V = 15 * 113.04
V = 1695.6 cubic centimeters.
Hence the total amount of chocolate in the box is 1695.6 [tex]cm^3[/tex].

Using the graph below with the following point find the length of the two diagonals to determine if TUVW is a rectangle or not T(-5,0) U(7,3) V(9,-6) W(-3,-9)
The lengths of each diagonal are given as follows:
[tex]TV = \sqrt{232}[/tex][tex]WU = \sqrt{244}[/tex]As the lengths are different, the polygon TUVW is not a rectangle.
How to obtain the diagonals?The diagonal length is obtained using the formula for the distance between two points, presented as follows:
[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
In which [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are the coordinates of each point.
The first diagonal is TV, and the length is given as follows:
[tex]TV = \sqrt{(9 - (-5))^2 + (6 - 0)^2} = \sqrt{232}[/tex]
The second diagonal is WU, and the distance is given as follows:
[tex]WU = \sqrt{(-3 - 7)^2 + (-9 - 3)^2} = \sqrt{244}[/tex]
A rectangle has diagonals of equal length, hence the polygon for this problem is not a rectangle.

The area of each rectangle is:
rectangle_1 = 7 * 20 = 140 cm2
rectangle_2 = 9 * 20 = 180 cm2
rectangle_3 = 9 * 20 = 180 cm2
