Eli's strawberry milk has a stronger strawberry taste than Arjun.

According to the question we have been given that

Arjun ,       adds milk = 90ml

                in strawberry syrup = 20ml

Eli,             adds milk = 180ml

                in strawberry syrup = 45ml

We need to find whose strawberry milk has stronger strawberry taste that is we have to find the concentration of the solution.

The formula for the concentration is given as :

   Concentration of the solution = [tex]\frac{volume of solute}{volume of solution}[/tex]  * 100%

For Arjun,  

        Volume of solvent = 90ml

      Volume of solute = 20ml

     Volume of solution = 20+90 ml = 110 ml

Concentration = (20/110)*100%

                        = 18.18%

For Eli,

         Volume of solvent = 180ml

      Volume of solute = 45ml

     Volume of solution = 180+45 ml = 225 ml

Concentration = (45/225)*100%

                        = 20%

As we can see that the Eli's concentration of the solution is greater than Arjun's. Hence Eli's strawberry milk has a stronger strawberry taste.

The measure of the sides is 27, 23 and 16 and the perimeter is 56 respectively

The triangle is a 2 dimensional shape that has 2 sides.

Given the following sides

l = m + n - 12

n = m - 7

m = l - 1/4n

l = m + 1/4n

Substitute

m + 1/4n = m + m - 7 - 12

m + 1/4(m-7) = 2m - 19

m + 1/4m - 7/4 = 2m - 19

-m + 1/4m = -19 + 7/4

-3/4m = -19(4)+7/4

-3/4m = -69/4

-3m = -69

m = 23

Hence the value of m from the given expression is 23

n = 23 - 7

n = 16

l = 23 + 16 -12

Answers:

4 liters of the 18% acid

8 liters of the 45% acid

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

Explanation:

Let's call the bottles A and B

x = amount, in liters, of bottle A used

12-x = amount, in liters, of bottle B used

Bottle A has 0.18x liters of pure acid

Bottle B has 0.45(12-x) liters of pure acid

These amounts must add to 0.36*12 = 4.32 liters of pure acid since we want 12 liters of a 36% solution.

So,

0.18x + 0.45(12-x) = 4.32

0.18x + 0.45(12)+0.45(-x) = 4.32

0.18x + 5.4-0.45x = 4.32

-0.27x + 5.4 = 4.32

-0.27x = 4.32 - 5.4

-0.27x = -1.08

x = (-1.08)/(-0.27)

x = 4 liters which is the amount of bottle A needed

12-x = 12-4 = 8 liters is the amount of bottle B needed

--------------------

Check:

Using 4 liters of bottle A means we contribute 4*0.18 = 0.72 liters of pure acid from this bottle alone.

Using 8 liters from bottle B adds another 8*0.45 = 3.6 liters of pure acid

Then, 0.72+3.6 = 4.32 which matches with the 4.32 mentioned earlier. Therefore, the answer is fully confirmed.

Using a system of equations, it is found that it sold 27 lower-priced speaker docks.

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

For this problem, the variables are given as follows:

Last week the store sold three times as many lower-priced speaker docks as higher-priced speaker docks, hence:

x = 3y -> y = x/3.

Combined sales totaled $3,870, hence, considering the price of each speaker:

80x + 190y = 3870.

Since x = 3y:

240y + 190y = 3870.

430y = 3870

y = 3870/430

y = 9.

Hence:

x = 3y = 3 x 9 = 27.

Answer:

[tex](1, -1)[/tex] and [tex](-\frac{1}{5}, \frac{7}{5})[/tex]

In decimal form this would be (1, -1) and (-0.2, 1.4)

Step-by-step explanation:

Basically here we are trying to solve a system of 2 equations. The first one is a straight line and the second is a circle. This can be done graphically and graph is attached. There will be two points where the line cuts the circle so two solution sets

The equations are

Line Equation [tex]y = 1 - 2x[/tex]    (1) and

Circle Equation [tex]x^2+ y^2 = 2[/tex]   (2)

[tex]y=1-2x[/tex]

Plug this value of y into the second equation for the circle
[tex]x^2 + (1-2x)^2= 2[/tex]

Apply the perfect squares formula [tex]\left(a-b\right)^2=a^2-2ab+b^2[/tex]

[tex](1-2x)^2 = 1^2-2\cdot \:1\cdot \:2x+\left(2x\right)^2\\= 1-4x+4x^2\\\\[/tex]

So equation (2) becomes
[tex]1-4x+4x^2 +x^2 = 2 \\\\\\5x^2 -4x - 1 = 0[/tex]

Solve using the quadratic formula
[tex]x_{1,\:2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

Here a is the coefficient of x ², b is the coefficient of x and  c is the constant

So
[tex]x_{1,\:2}=\frac{-\left(-4\right)\pm \sqrt{\left(-4\right)^2-4\cdot \:5\left(-1\right)}}{2\cdot \:5}[/tex]

Now,

[tex]\sqrt{\left(-4\right)^2-4\cdot \:5\left(-1\right)} = \sqrt{\left(-4\right)^2+4\cdot \:5\cdot \:1}[/tex]

= [tex]\sqrt{16+20} = \sqrt{36} = 6[/tex]

Therefore
[tex]x_{1,\:2}=\frac{-\left(-4\right)\pm \:6}{2\cdot \:5}[/tex]

[tex]x_1=\frac{-\left(-4\right)+6}{2\cdot \:5}[/tex] = [tex]\frac{-\left(-4\right)+6}{2\cdot \:5} =[/tex]  [tex]\frac{10}{2\cdot \:5}[/tex] [tex]= 1[/tex]

[tex]x_2 = \frac{-\left(-4\right)-6}{2\cdot \:5}[/tex] [tex]= \frac{4-6}{2\cdot \:5}[/tex] = [tex]-\frac{1}{5}[/tex]

To find corresponding values for [tex]y_1 y_2[/tex] plug these values of [tex]x_1, x_2[/tex] into the line equation

[tex]y_1 = 1- 2(1) = -1[/tex]
[tex]y_2 = 1 - 2(-\frac{1}{5}) = 1 + \frac{2}{5} = \frac{7}{5}[/tex]

So the two points of intersection are

[tex](1, -1)[/tex] and ([tex](-\frac{1}{5}, \frac{7}{5})[/tex].

In decimal form this would be (1, -1) and (-0.2, 1.4)

Antonio can make 6 whole loaves of bread, and he will be left with 1/2 cup of flour, which is used to make 3/4th of a loaf.

In the question, we are given that Antonio is making bread. He has 9/2 cups of flour. We are also informed that each loaf uses 2/3 cup of flour.

We are asked for the number of whole loaves of bread that Antonio can make, and also, we are asked whether he will be left with some flour or not. If yes, then how much?

To find the number of loaves Antonio will make, we will divide the quantity he has by the quantity required for one loaf.

Thus, the number of loaves = (9/2) ÷ (2/3) = 9/2 × 3/2 = 27/4 = 6 3/4.

We will ignore the fractional part as we are asked for whole loaves. Thus, we can say that Antonio will make 6 whole loaves.

Also, he will be left with 3/4th of a loaf, that is, 3/4 of 2/3 cup of flour = 1/2 cup of four.

Thus, Antonio can make 6 whole loaves, and he will be left with 1/2 cup of flour, which is used to make 3/4th of a loaf.

By concept of translation, the coordinates of new triangle A'B'C' are given as follows:

A' (14, 3), B' (-6,2), C (-8, 6).

A translation can be define or represented by a change in the graph of a function, which are done by the means of operations such as multiplication, addition or subtraction either in it’s range(i.e. the values of y) or in it’s domain(i.e. the values of x). Examples are compression of points or shifting  left right or bottom up, stretching and reflections over the axis that is the x-axis or the y-axis, or rotations around the origin.

For the given question, the translation rule is given as follows:

(x , y) -> (2x, y-3).

Applying the rule to each point of triangle, we have that:

A': (2(7), 6-3) = (14, 3).

B': (2(-3), 5-3) = (-6, 2).

C': (2(-4), 9-3) = (-8, 6).

with the original length as 15.17 feet and the new length as 18.57 feet, there is an increase of 22.41 % in the length of the garage.

We are given that Yossi has a garage of area = 230 feet²

We know that area of square is:

A = side²

230 = s²

s = √ 230

s = 15.17 feet

Now area is increased by 50 %

New area = 230 + 50% of 230

A' = 230 + 115

A' = 345 feet²

s² = 345

s = √ 345

s = 18.57 feet

Percent increase in length = 18.57 - 15.17 / 15.17 × 100

Let B denote the number of children wearing black costumes to the party.

Then n(B) = 18

Let O denote the number of children wearing orange costumes to the party.

Then n(O) = 12

We are asked to find how many children will wear both orange and black. That is to find n(B ∩ O).

We are also given that half of the guests are wearing costumes that are neither black nor orange.

Then n(B ∪ O)' = n(P)/2 = 46/2 = 23, where n(B U O)' denotes the complement of n(B U O).

We also know that n(B ∪ O) = n(P) - n(B U O)' = 46 - 23 = 23

⇒ n(B U O) = n(B) + n(O) - n(B ∩ O)

⇒ 23 = 18 + 12 - n(B ∩ O)

⇒ 23 = 30 - n(B ∩ O)

⇒ n(B ∩ O) = 30 - 23 = 7
