Is 0 infinite or no solution?.

The quadratic formula is an algebraic formula that provides the solutions to a quadratic equation. A quadratic equation is an equation of the shape ax^2 + bx + c = 0, where a, b, and c are constants.

The quadratic formula gives the values of x that satisfy the equation and is expressed as:

x = (-b ± √ (b^2 - 4ac)) / (2a)

In other words, the quadratic formula provides a method for finding the two roots of a quadratic equation, even if the equation cannot be solved by factoring or other methods.

The formula works for all quadratic equations and is a widely used tool in mathematics and various scientific and engineering fields.

The reason why a chemical equation have to follow the law of conservation of mass is that the mass of the products and the mass of the reactants must be equal.

Antoine Lavoisier discovered in 1789 that mass is neither created nor destroyed in chemical reactions, which led to the formulation of the Law of Conservation of Mass. To put it another way, the mass of any one element at the start of a reaction will be equal to that element's mass at the end of the reaction. . When the total mass of atoms on both sides of a chemical reaction is equal, the reaction is said to be balanced.

According to the rule of conservation of mass, mass is neither generated nor destroyed during a chemical process. The carbon atom in coal, for instance

To solve the 3 4 5 triangle method to find the sides of the right-angle triangle we use the Pythagoras theory.

One type of triangle that has one right (90°) angle is a right triangle.

The Greek mathematician Pythagoras is credited with creating a mathematical formula for calculating the length of the third side of a right triangle given the lengths of the other two sides.

The triangle's right angle is formed by the sides of variables a and b. Either side may utilize either variable. The side that is left, or the side that leans away from the right angle, is represented by the variable c. The hypotenuse, or side c, is the longest side and is always present.

Thus, To solve the 3 4 5 triangle method to find the sides of the right-angle triangle we use the Pythagoras theory.

Answer:

C)  S: {20, 40}

Step-by-step explanation:

Given inequality:

[tex]\dfrac{1}{5}(m-5)\leq \dfrac{1}{10}(m-20)[/tex]

To solve the inequality, multiply both sides by 10:

[tex]\implies \dfrac{10}{5}(m-5)\leq \dfrac{10}{10}(m-20)[/tex]

[tex]\implies2(m-5)\leq m-20[/tex]

Expand the left side:

[tex]\implies 2m-10 \leq m-20[/tex]

Subtract m from both sides:

[tex]\implies m-10 \leq -20[/tex]

Add 10 to both sides:

[tex]\implies m \leq -10[/tex]

Therefore, the true solution set to the given inequality are values of m that are less than or equal to -10.

Answer: List 2

Mark the midpoint between 1/6 and 1/2 (see diagram below)

======================================================

Explanation:

There are 3 meats (ham, turkey, bologna) and 2 vegetables (carrots, celery).

This gives 3*2 = 6 different combos of meat plus a vegetable. This is where we can only pick one of each type.

The 6 different combos are shown in  list 2  

List 1 is not correct because you can choose one vegetable only, and not have both.

----------

Look through list 2 and circle the options that say "ham, carrots" and "turkey, carrots". There are 2 items that are circled. This is out of 6 total.

We arrive at the probability 2/6 = 1/3

The fraction 2/6, aka 1/3, is located at the halfway point between 1/6 and 1/2. This is because 1/6+1/2 = 1/6+3/6 = 4/6, which divides in half to get 2/6.

Answer:

25 cashiers

Step-by-step explanation:

To solve this, you can multiply the number of cashiers at 10:00 am (20) by 1 1/4, which is the same as multiplying by 5/4.

20 x 5/4 = 25

So, there are 25 cashiers at 4:00 pm.

You can confirm this by dividing 25 by 5/4 to see if it equals 20:

25 * 4/5 = 20

Therefore, there are 25 cashiers at 4:00 pm.

A function which has the greater initial value include the following: linear function A.

In Mathematics, the y-intercept is sometimes referred to as an initial value and the y-intercept of any graph such as a linear function, generally occur at the point where the value of "x" is equal to zero (x = 0).

By critically observing the table of values for linear function A, we can reasonably and logically deduce that its y-intercept (initial value) is equal to 8 when the value of "x" is equal to zero (x = 0).

For linear function B, we would substitute the value of x with zero (0) as follows;

The container holds more than 3 cups of sugar, since it holds 3 times the amount used in the recipe.

To calculate the amount of sugar in the container, we need to first determine the amount used in the recipe. The recipe calls for 2 1/3 cups of sugar. This can be converted to a decimal by dividing by 3, resulting in 2.333 cups of sugar used in the recipe. Now that we know the amount used, we can calculate the amount the container holds.

1. 2 1/3 cups = 2.33 cups

2. 3 x 2.33 cups = 6.99 cups

The container holds 3 times the amount used, so we can multiply 2.333 cups by 3, resulting in 6.999 cups of sugar in the container. This is more than 3 cups of sugar, so the container holds more than 3 cups of sugar.

The logarithm of a number with respect to a base is the exponent to which the base must be raised to produce that number. In other words, log_b(x) = y means b^y = x.

To find log_7(x), we can use the change of base formula which is log_b(x) = log_c(x) / log_c(b).

So you can use the logarithm of base 10 (common logarithm) or base e (natural logarithm) and use the above formula to find log7

So for example, log7(49) = log10(49) / log10(7) or log7(49) = ln(49) / ln(7)

There are 4 rows of Soprano. The concept of algebraic manipulation is used to solve the problem.

Given the information that there are 64 fingers in total and 8 fingers in each row of the Tenor, I was able to determine that there are 32 fingers in the Tenor rows by multiplying 8 fingers/row x 4 rows.

Then, We subtracted the number of fingers in the Tenor rows (32 fingers) from the total number of fingers (64 fingers) to find the number of fingers in the Soprano rows, which is also 32 fingers.

Finally, We divided the number of fingers in the Soprano rows by the number of fingers per row (8 fingers/row) to find the number of rows of Soprano, which is 4 rows.

If there are 64 fingers in total and 8 fingers in each row of the Tenor, then there are 8 fingers / row x 4 rows = 32 fingers in the Tenor rows.

Since there are 64 fingers in total and 32 fingers in the Tenor rows, then there are 64 fingers - 32 fingers = 32 fingers in the Soprano rows.

Therefore, there are 32 fingers / 8 fingers/row = 4 rows of Soprano.

Yes, the trinomial 9z 30z + 25 is a perfect square. The square of the binomial equation can be used to construct a perfect square trinomial statement.

A trinomial of the form + bz + c is said to be a perfect square if and only if it satisfies the condition b = 4ac.In a perfect square trinomial, two of your words will be perfect squares. If two perfect square terms are absent, the trinomial is not a perfect square trinomial.

It is now necessary to calculate the square roots of each perfect square word, add the two square roots, and multiply the result by two. The square of this trinomial is perfect. Because both 922 = (3ae)° and 25 = 52 are perfect squares, the only thing left to decide is if the middle term matches when you square (3x-5).In order to at least produce a negative coefficient for the middle phrase, the minus sign was utilised.
