Answer:

Amount of  vinegar. 100% : 20 milliliters

Amount of  Italian dressing: 140 milliliters

Step-by-step explanation:

Let's call A the amount of  vinegar. 100%

Let's call B the amount of  Italian dressing . 12% vinegar

The resulting mixture should have 23%  vinegar, and 160 milliliters.

Then we know that the total amount of mixture will be:

Then the total amount of pure antifreeze in the mixture will be:

Then we have two equations and two unknowns so we solve the system of equations. Multiply the first equation by -1 and add it to the second equation:  We substitute the value of B into one of the two equations and solve for A.

Answer:

[tex]Mother = 30\ years[/tex]

[tex]Son = 10\ years[/tex]

Step-by-step explanation:

Given

[tex]M = Mother[/tex]

[tex]S = Son[/tex]

From the first statement:

[tex]M = 3S[/tex]

From the second:

[tex]M - S = 20[/tex]

Required

Find M and S

We have:

[tex]M = 3S[/tex] and

[tex]M - S = 20[/tex]

Substitute [tex]M = 3S[/tex] in [tex]M - S = 20[/tex]

[tex]3S -S =20[/tex]

[tex]2S = 20[/tex]

Divide both sides by 2

[tex]S = 10[/tex]

Substitute [tex]S = 10[/tex] in [tex]M = 3S[/tex]

[tex]M = 3 * 10[/tex]

[tex]M = 3 0[/tex]

Hence;

[tex]Mother = 30\ years[/tex]

[tex]Son = 10\ years[/tex]

Answer:

Step-by-step explanation:

CI ( 95 % )   means   α = 5 %    α  = 0,05   α /2 = 0,025

If we have a normal distribution and build a CI by symmetry such CI has as a middle point the mean in this case

CI 95 %  =  ( 520 ;  560 )

the mean is (520 + 560 ) / 2  

mean  = 540

Answer:

If we know the area of the circle we can find the radius by using the formula for

Area = πr²

Answer:

The diameter is always double the radius. Hence, the formula is derived by dividing the diameter by 2.

Step-by-step explanation:

                  Radius Formulas

v - at = u

u = v - at

Answer:

Which function is represented by this graph?

9

The last option is not even a function, because it ambiguously defines the endpoints.

The first option doesn't define the endpoint, because they are always excluded.

So, the correct option is the second one, because it includes the left endpoint and excludes the right one

m<QRS = 80 degrees.

Supplementary angles = a total of 180 degrees. So if angle ABC = 100, angle QRS would = 80 degrees.

Please mark as brainliest :D

Answer:

Solution given:

<ABC+<QRS=180°[supplementary]

<QRS=180°-100°

<QRS=80° is your answer

Answer:

The expanded form is y=716x7

Step-by-step explanation:

Expanded form or expanded notation is a way of writing numbers to see the math value of individual digits. When numbers are separated into individual place values and decimal places they can also form a mathematical expression. 5,325 in expanded notation form is 5,000 + 300 + 20 + 5 = 5,325.

Answer:

Step-by-step explanation:

Parts + 3($40 labor)=183.30

parts + 120=183.30

parts=63.30 but it includes tax. To find costs of parts before tax you

63.30/1.055=60 so parts are $60

or to solve with one equation:

parts(1.055) + 3($40 labor) = 183.30

parts(1.055) + 120=183.30

parts(1.055)=63.30

Parts = 63.30/1.055

parts = 60
