Answer:

46.91%

Step-by-step explanation:

The first solution contains 11 * 0.25 = 2.75 L of vinegar

The second solution contains 12 * 0.67 = 8.04 L of vinegar

When mixed together, that adds up to 8.04 + 2.75 = 10.79 L of vinegar

The total volume of the combined solutions is 11 + 12 = 23 L of solution

So the new concentration is 10.79/23 ≈ 0.4691 ≈ 46.91%

Answer:

The output is 5

Step-by-step explanation:

y=x+2,

Let x =3

y = 3+2

y = 5

The output is 5

Answer:

5

Step-by-step explanation:

We are given the relation:

y=x+2

The input is also called "x", and the output is also known as "y". We want to find the output, or y, when x is equal to 3.

Therefore, we must substitute 3 in for x and solve.

y= x+2 at x=3

y=3+2

Add 3 and 2.

y=5

If the relation is y=x+2 and the input is 3, then the output is 5.

Answer:

230 capsules.

Step-by-step explanation:

The following data were obtained from the question:

Taste >>>>>>>>>>> Frequency

Volluto >>>>>>>>>> 12

Livanto >>>>>>>>>> 7

Ristretto >>>>>>>>> 23

Cosi >>>>>>>>>>>> 3

Other >>>>>>>>>>> 5

Next, we shall determine the total frequency.

This is illustrated below:

Total frequency = 12 + 7 + 23 + 3 + 5

Total frequency = 50

Finally, we shall determine the number of Ristretto in 500 capsules.

This can be obtained as follow:

Number of Ristretto = Frequency of Ristretto /total frequency x total capsule

Frequency of Ristretto = 23

Total frequency = 50

Total capsule = 500

Number of Ristretto = 23/50 x 500

Number of Ristretto = 23 x 10

Number of Ristretto = 230.

Therefore, the number of Ristretto in the 500 capsules is 230.

Answer:

4sqrt(2) + 1

Step-by-step explanation:

Well you know that cos 0 is 1

this means that a+b = 9

cos 60 is 1/2

this means 1/2 a + b = 5

a = 8

b = 1

now plug in for x = 45

cos 45 = sqrt(2)/2

Answer:

-3x+10y

Step-by-step explanation:

Given the expression [tex]-4\left(2x-y\right)+y+5\left(x+y\right)[/tex], we are to simplify by combining the like terms. On simplification we have;

[tex]= -4\left(2x-y\right)+y+5\left(x+y\right)[/tex]

Open the parenthesis:

[tex]= -4(2x)-4(-y)+y+5(x)+5(y)\\\\= -8x+4y+y+5x+5y[/tex]

Collect the like terms:

[tex]= -8x+5x+4y+y+5y[/tex]

Sum up the resulting expression

[tex]= -8x+5x+4y+y+5y\\= -3x+10y[/tex]

Hence the required expression on simplification is -3x+10y

Given equation: [tex]x^2 = -8x -7[/tex]

To solve the quadratic equation, we will need to set one side of the equation equal to 0. This can be done by subtracting x² on both sides.

[tex]\implies x^2 - x^2= -8x -7 - x^2[/tex]

[tex]\implies 0= -8x -7 - x^2[/tex]

To further simplify, we can factor -1 from the expression on the R.H.S. Then, we can cancel the -1 since there is a 0 on the other side.

[tex]\implies 0= -1(8x + 7 + x^2)[/tex]

[tex]\implies 0= 8x + 7 + x^2 = x^2 + 8x + 7[/tex]

Finally, factor the expression on the right hand side.

Factoring a quadratic equation can be done in 2 ways.

In this method, we split the middle term into two suitable terms. The suitable terms must follow two conditions.

Then, we factor the first two terms of the expression and the last two terms of the expression. Eventually, we will get a common expression. So, we can further factorize to get a product of two expressions.

In this method, we will compare our equation with the standard form equation to determine the a, b, and c variables. Then, we plug the variables into the formula and simplify to get the roots (solutions).

[tex]\text{Quadratic Formula:} \ \dfrac{-b\ \± \sqrt{b^{2} - 4ac} }{2a}[/tex]

We can use any method to solve for the roots. First, let us check whether the middle term could be split into two suitable terms such that those terms could meet the criteria stated above.

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

We can see that 8x is the middle term and it can be split into the sum of 7x and x. The product of the (middle term) coefficients is 7. The product of the coefficients (first and last terms) is also 7. Since both products match, we can use the splitting method to factorize the expression.

[tex]\implies 0= x^2 + 8x+ 7[/tex]

[tex]\implies 0= x^2 + x + 7x+ 7[/tex]

Now, factor the first two terms and the last two terms separately.

[tex]\implies 0= x^2 + x + 7x+ 7[/tex]

[tex]\implies 0= x(x + 1) + 7(x+ 1)[/tex]

We can see a common expression. Finally, let us factor the common expression to get a product of two expressions.

[tex]\implies 0= (x + 7)(x + 1)[/tex]

Since the factorized expression equals to 0, we can set each expression (inside the parentheses) equal to 0.

[tex]\implies x + 7 = 0; x + 1 = 0[/tex]

[tex]\implies x = -7; x = -1[/tex]

Now, let us try to solve using the Quadratic formula.

[tex]0= x^2 + 8x+ 7[/tex]

Tip: Standard form: 0 = ax² + bx + c

Comparing both equations will allow us to determine the a, b, c variables.

⇒ a = 1; b = 8; c = 7

Now, let us plug these values into the quadratic formula and simplify.

[tex]\implies \dfrac{-b\ \± \sqrt{b^{2} - 4ac} }{2a}[/tex]

[tex]\implies \dfrac{-8\ \± \sqrt{8^{2} - 4(1)(7)} }{2(1)}[/tex]

[tex]\implies \dfrac{-8\ \± \sqrt{64 - 28} }{2}[/tex]

[tex]\implies \dfrac{-8\ \± \sqrt{36}}{2} = \dfrac{-8\± 6}{2} = \dfrac{-8 + 6}{2},\ \dfrac{-8 - 6}{2} = \dfrac{-2}{2} ,\ \dfrac{-14}{2} = -1 , -7 \ \text{(B)}[/tex]

Therefore, in both methods, the answer is -1, -7 (B).

Answer:

Sharika needs 2.5 days to finish the remaining work

Step-by-step explanation:

Sharika can do a work in 6 days palkey can do it in 8 days

Then the amount of work sharika can do in 1 day = 1/6

And the amount of work palkey can do in 1 day = 1/8

The amount of work both of them can do together in 1 day = 1/6 + 1/8

= 7/24

The amount of work both of them can do together in 2 day = (2× 7/24)

= 7/12

Since Palkey left the work,the amount of

work remaining for Sharika to do alone = (1 - 7/12 )

= 5/12

The number of days Sharika take to finish the remainig work. = (5/12 ÷ 1/6 )

= 5/2 days

Therefore, Sharika needs 2.5 days to finish the remaining work.

Value of miles traveled (m) = 13 mile

Step-by-step explanation:

Given:

Equation

3.00 + 0.50 m = 9.50

Find:

Value of miles traveled (m)

Computation:

3.00 + 0.50 m = 9.50

0.50 m = 9.50 - 3.00

0.50 m = 6.50

m = 6.50 / 0.50

m = 13

Value of miles traveled (m) = 13 mile

Answer:

The question is not complete, below is the complete question:

A taxi driver wrote a formula to represent the mileage and fee for his last customer. He wrote the equation 3.00 + 0.50 m = 9.50, where m represents the number of miles traveled.

Which statement shows the meaning of the driver's equation? Check all that apply.

a.) Three dollars added to $0.50 is the same as $9.50.

b.) Three dollars plus $0.50 times the number of miles is equal to nine dollars and fifty cents.

c.) Three dollars more than the quotient of $0.50 and the number of miles is nine dollars and fifty cents.  

d.) The product of the number of miles and the sum of $3 and $0.50 is equal to $9.50.

e.) The sum of three dollars and the product of 50 cents times the number of miles is nine dollars and fifty cents.

Answers

The correct answers are:

b

e.) The sum of three dollars and the product of 50 cents times the number of miles is nine dollars and fifty cents.

Step-by-step explanation:

The formula written by the driver is: 3.00 + 0.50 m = 9.50

where m = number of miles travelled

This means that when the product of 0.50 and the number of miles travelled 'm' is added to $3, the result is 9.50

And this is the same explanation as the following options:

a.) Three dollars($3) plus $0.50 times the number of miles is equal to nine dollars and fifty cents($9.50).

e.) e.) The sum of three dollars and the product of 50 cents times the number of miles is nine dollars and fifty cents;

note that 50 cents is the same as $0.50

After raising the walls of the building of height 2cm 5 times the height of the wall will be 10cms.

Multiplication is a short hand of addition like if we have to add 2 by100  times it is same as multiplying 2 with 100 which is 200.

According to the given question Bryce is making a model building.

Said that he raises the walls of the building by 2 centimeters five times.

So, Either we can sum 2 centimeters 5 times which is (2 + 2 + 2 + 2 + 2) which is

= 10cms.

Or we can multiply the height of the building which is 2 cm by the no. of times he raised it which is 5.

∴(2×5) = 10cms.
