[tex]2 \div \frac{12}{5} \\ = 2 \times \frac{5}{12} \\ = \frac{10}{12} \\ = \frac{5}{6} \\ = 0.83[/tex]
Answer: 5/6
Step-by-step explanation: Another way of writing this problem is 2/1 ÷ 12/5. To solve this division problem, you must multiply the recipricol of the divisor. The recipricol of 12/5 is 5/12, so the new expression will look like this: 2/1 x 5/12. You can solve this by multiplying the numorators and then multiplying the denonimators to get 10/12. The simplified version of 10/12 can be expressed as 5/6.

Step-by-step explanation: in the linear equations y= Kx shows the proportionality relations . Where k is the proportionality constant which can be any number . x an y are the variables, so according to this answer will be y=3/
Answer:
y=3/4x
Step-by-step explanation:
Let's first define some words;
Proportional: If a line or a ray through the origin it proportional
Non proportional: If a line or ray that does not pass through the origin
Origin: Initial point or the starting point
Now we have define the words now let's graph these points by using Desmos.
Graphs are shown below.
Base on the graphs below we can see that;
y=3/4x pass through the origin which means the that this linear equation is proportional.

Brigid has a 25-foot ladder she will use to paint the side of her house. What angle does the ladder need to make with house so she can reach 18 feet up the side of her house
The ladder needs to make an angle of approximately 54.7 degrees with the house in order for Brigid to reach 18 feet up the side of the house.
To determine the angle the ladder needs to make with the house, we can use the tangent function.
First, we'll need to determine the opposite side (the height that the ladder needs to reach) and the adjacent side (the distance from the base of the ladder to the house) of the triangle formed by the ladder and the house.
Opposite side = 18 feet
Adjacent side = 25 feet
We can then use the tangent function to find the angle:
tan(angle) = opposite / adjacent
Solving for the angle, we get:
angle = arctan(18/25) = approximately 54.7 degrees
Therefore, the ladder needs to make an angle of approximately 54.7 degrees with the house in order for Brigid to reach 18 feet up the side of the house.

1.) What is the length of x?
2.) What is the area of the right triangle inside of the parallelogram?
Answer:
The area of x is 4
The area of the right triangle is 6
Step-by-step explanation:
The Pythagorean Theorem can be used when dealing with right triangles. So, if we use the equation a^2 + b^2 = c^2, we can find that 3^2 + x^2 = 5^2 or 9 + x^2 = 25. If we calculate, we can find that x is equal to 4. Now if we multiply by 3 and divide by 2, we can get the answer of 6 as the area of the right triangle.

The true equations are - 15·0 = 015·0, 1.4 + 2.7 = 4.1, and 4(2/3) = 5-(1/3).
What is an equation?
A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").
The first equation is -
5 + 0 = 0
This equation is false, as if 0 is added to any number, the result is the same number itself, and not 0.
The second equation is -
15·0 = 015·0
Any number multiplied by 0, gives the result as 0.
In the above equation LHS = RHS = 0.
Hence, this equation is true.
The third equation is -
1.4 + 2.7 = 4.1
Solving LHS -
= 1.4 + 2.7
= 4.1
So, LHS = RHS and hence, this equation is true.
The fourth equation is -
(2/3) · (5/9) = 7/12
Solving LHS -
= (2/3) × (5/9)
= 10/27
Here, LHS ≠ RHS.
Hence, this equation is false.
The fifth equation is -
4(2/3) = 5-(1/3)
Solving LHS -
4(2/3) = 14/3
Solving RHS -
= 5 - 1/3
= (15 - 1)/3
= 14/3
Therefore, LHS = RHS and hence, this equation is true.

Choose two statements that are true for this expression.
6x3 -8x^2- 40/y+21
Observing the given equation, The answer is The degree of polynomial is 3 and the equation has variables 'x' and 'y'.
What do you mean by equation?An equation is a mathematical statement that asserts the equality of two expressions. It typically consists of two expressions separated by an equals sign (=), for example, 2 + 2 = 4. Equations can be used to express relationships between different quantities and can be used to solve problems in many areas of mathematics and science. Equations can also be represented graphically, and they can be manipulated or transformed to make solving them easier.
What is degree of polynomials?A polynomial is a mathematical expression that is made up of a sum of powers in one or more variables. The degree of a polynomial is the highest power of the variable(s) present in the polynomial. For example, in the polynomial expression 3x^2 + 2x - 5, the highest power of x is 2, so the degree of the polynomial is 2. A degree 0 polynomial is a constant polynomial, which is just a number. The degree 1 polynomial is a linear equation, and degree 2 polynomial is a quadratic equation. In general, the degree of a polynomial can give an idea about the behavior of the polynomial function. As the degree of a polynomial increase, the shape of the function become more complex.

Mrs. Sanders has three grandchildren, who call her regularly. One calls her every three days, one calls her every four days, and one calls her every five days. All three called her on December 31, 2016. On how many days during the next year did she not receive a phone call from any of her grandchildren
By probability, she will not receive a phone call from any of her grandchildren after 146 days
How does probability affect our lives?In those circumstances, probability helps in assessing the likelihood of an event. Probability plays a significant role in daily life. political strategy analysis, blood type determination, sports and gaming strategies, insurance buying or selling, online shopping, and online gaming.
There is a [tex]\frac{2}{3}[/tex] chance that the first child won't call, a [tex]\frac{3}{4}[/tex] chance that the second child won't call, and a [tex]\frac{4}{5}[/tex] chance that the third child won't call on any given day. There is a [tex]\frac{2}{3} *\frac{3}{4} * \frac{4}{5} = \frac{2}{5}[/tex] chance that no child calls her on a randomly selected day.
When we consider a sample of 360 days, in particular, this "unrigorous" reasoning becomes rigorous due to linearity of expectation; over the first 360 days, 360 * 2/5 = 144 days will pass without a phone call. Now, we just check the remaining days. On days $361 and $362, no one calls her. On days 363 and 364, she receives calls from children every three and four days, respectively. On day 365, she receives calls every five days. Therefore, to get our answer of 146, we two more days in 144.
