URGENT!

A scientist begins an experiment with 20.25 milliliters of a chemical. She adds 0.75 milliliter of water to the chemical every 10 minutes, starting at 1:30 P.M.

The scientist continues adding the 0.75 milliliters to the mixture until amount of chemical and water are EQUAL. At that point she uses 2/3 of the mixture for further experiments.

How many milliliters of the mixture are unused?

Answer:

just divide them

Answer:

m = 810 movies

Step-by-step explanation:

6,840 = 3(1740) + 2m

6,840 = 5,220 + 2m

Subtract 5,220 on both sides

1,620 = 2m

Divide each side by 2

m = 810

Answer:

p(x)=(2x²-9x+7)(x-2)

=(2x²-2x-7x+7)(x-2)

Answer:

4 bottles of Water

Step-by-step explanation:

First, we need to find how much each water costs. So, I created this equation below.

9/12=?

The answer to the equation is .75, or 75 cents.

So, we can now make yet another equation to find the amount to buy with 3 dollars.

3/.75=?

The answer to that equation is 4.

Thus, the answer is 4 bottles of water.

Answer:

x=50

Step-by-step explanation:

since its an isosceles triangle, both of the base angles are going to be the same. Since all of a triangle's angles combined equal 180, and you already have one angle, subtract the 80 from 180.

this leaves you with 100. since there are two angles left, divide 100 by two and thats the value of x

hope this helps!! :)

Answer:

50?

Step-by-step explanation:

I would say 50 because x and the blank angle looks the same and 80+x+?=180

80+x2=180

x*2=100

x=50

Answer:

180 ahhahaahahhahaahahahhaa

Answer:

180

Answer:

10

Step-by-step explanation:

The measure of an angle∠I  is 10 degrees between the 450 cm and 640 cm sides.

The Law of Cosines (also called the Cosine Rule) is defined as it relates all three sides of a triangle with an angle of a triangle.

c² = a² + b² − 2ab cos(C)

The cosine rule, also known as the law of cosines, relates all 3 sides of a triangle with an angle of a triangle. it relates the lengths of the sides of a triangle to the cosine of one of its angles.

In the given triangle ΔHIJ,

Sides:

h = 450 m

i = 210 m

j = 640 m

The angle of ∠I  is 10 degrees between the 450 cm and 640 cm sides.

According to the cosine rule,

j² = h² + i² − 2ab cos(I)

Substitute the values in the Cosine Rule,

450² = 210² + 640² - 2(210)(640)cos(I)

After solving we get the value of  angle ∠I :

∠I = 9.56038°

Rounded to the nearest degree.

∠I = 10°

Thus, the measure of an angle∠I  is 10 degrees.

Step-by-step explanation: to find 2/6 we can start with finding 1/6 because it’s easier. To do that we divide 30 by 6 which equals 5. because 5 is 1/6 5x2 is 2/6 so the answer is 10

Answer:

you put 30 over 1 than you then you 2 over 6 then subtract then

Step-by-step explanation:

so it would look like this

30/1 - 2/6=

Answer: The answer is x=3/7.

Step-by-step explanation:

So first you subtract on both sides by 5x and get -7x+6=3 then subtract 6 on both sides so you get -7x=-3 then lastly divide by -7 which is x=3/7. I hope this helps. The point of this problem is to isolate the x variable.

The solution to the equation 6 - 2x = 3 + 5x is x = 3/7.

Given that,  the equation 6 - 2x = 3 + 5x.

As for an example of a different equation, consider the equation 2y + 5 = 17.

To solve this equation, isolate y:

2y = 17 - 5

2y = 12

y = 12/2

y = 6

The solution set for this equation is y = 6.

In general, the solution set can have various forms, such as a single value, multiple values, an interval, or even an infinite set of solutions, depending on the equation and its variables.

To solve the equation 6 - 2x = 3 + 5x, to isolate the variable x on one side of the equation.

Simplify the equation step by step:

6 - 2x = 3 + 5x

First,  gather the x terms on one side and the constant terms on the other side:

-2x - 5x = 3 - 6

Combining like terms:

-7x = -3

Next,  isolate x by dividing both sides of the equation by -7:

x = (-3) / (-7)

Simplifying the right side:

x = 3/7

The solution set is a collection of values or a range of values that satisfy the given equation. In this case, the solution set consists of a single value, which is x = 3/7.

Therefore, the solution to the equation 6 - 2x = 3 + 5x is x = 3/7.

Answer: chemical decomposition produced by passing an electric current through a liquid or solution containing ions. In chemistry and manufacturing, electrolysis is a technique that uses direct electric current to drive an otherwise non-spontaneous chemical reaction. Electrolysis is commercially important as a stage in the separation of elements from naturally occurring sources such as ores using an electrolytic cell. Electrolysis is used in industry for the production of many metals and non-metals (e.g., aluminium, magnesium, chlorine, and fluorine). Electrolysis is commonly employed for coating one metal with another. The method of coating one metal with another using an electric current is called electroplating.

62° + 28°

First, we must determine the slope, then we find the y-intercept using slope formula and slope-intercept form.

For slope:

[tex]m = \frac{5 + 2}{-3 + 4} = \frac{7}{1} = 7[/tex]

Slope (m) = 7

For y-intercept:

[tex]5 = 7(-3) + b\\\\5 = -21 + b\\\\26 = b[/tex]

Y-intercept (b) = 26

Using this information, we can now create the equations for this line.

[tex]y= 7x + 26\\\\y - 5 = 7(x + 3)[/tex]

Formulas:

Slope formula: y₂ - y₁/x₂ - x₁

Slope-intercept form: y = mx + b

Point-slope form: y - y₁ = m(x - x₁)

*Note: (x₁, y₁), (x₂, y₂) = 2 points on the line
