Answer:

18 Milk Chocolates: 24 dark chocolates

Step-by-step explanation:

The total number of chocolates are 42

So you have Milk: Dark, in the ratio 3:4

You do 3+4 which = 7

You then divide the total ratio outcome by the total number

So you do, 42/7 =6

You then do 6 and put this into the ratio

So you do, 3x6 and 4x6, which = 18 and 24

To check if your answers correct add the ratio outcomes

And If you add 18 and 24 together, you should get your beginning total of 42

Answer:

Sadie took 47 minutes to finish her test.

Step-by-step explanation:

Let Laura's time be x minutes.

Then we have:

x + 3x - 16 = 68

4x = 84

x = 21 minutes.

So Sadie took 3(21) - 16 = 63-16

= 47 minutes.

Answer:

the answer is b

Answer:

First Number = 9

Second Number = -4

Step-by-step explanation:

Let the first number be "x" and the 2nd number be "y"

First number PLUS twice 2nd is 1, so we can write:

x + 2 y = 1

Twice First number PLUS the 2nd number is 14, so we can write:

2x + y = 14

We can write:

y = 14 - 2x

We put this into 1st equation and solve for x:

x + 2y = 1

x + 2(14 - 2x) = 1

x + 28 - 4x = 1

-3x = -27

x = 9

And now y:

y = 14 - 2(x)

y = 14 -2(9)

y = 14 - 18

y = -4

First Number = 9

Second Number = -4

Answer:

[tex]x=36\°\\\angle P=71 \°,\angle N=73 \°,\angle M=36 \°[/tex]

Step-by-step explanation:

Given:

The triangle is shown below.

We know that the sum of all interior angles of a triangle is equal to 180°.

Therefore,

[tex]\angle M+\angle N+\angle P=180 \°\\\\x+2x+1+2x-1=180\°\\\\5x=180\°\\\\x=\frac{180}{5}\\\\x=36\°[/tex]

Now, plugging the value of 'x' in each angle measure and determining its values. We get:

[tex]\angle M=x=36\°\\\angle P=2x-1=2(36)-1=72-1=71\°\\\angle N=2x+1=2(36)+1=72+1=73\°[/tex]

Therefore, the value of 'x' is 36° and the measure of the three angles are 36°, 71° and 73°.

The same solution of the given system of equations will be same as the solution of below system of equations;

⇒ 8x + 4y = −4

17x + 2y = −28

Option A is true.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The System of equation is,

6x + 2y = - 6   ..(i)

3x - 4y = - 18   ..(ii)

Now,

Solve the given system of equation as;

The System of equation is,

6x + 2y = - 6   ..(i)

3x - 4y = - 18   ..(ii)

By equation (i);

6x + 2y = - 6  

2(3x + y) = - 6

3x + y = - 3  ..(iii)

Subtract equation (ii) from (iii), we get;

3x - 4y - (3x + y) = - 18 - (-3)

3x - 4y - 3x - y = - 18 + 3

- 5y = - 15

y = 3

And, By equation (i), we get;

6x + 2y = - 6  

6x + 2 × 3 = - 6

6x + 6 = - 6

6x = - 6 - 6

6x = - 12

x = - 2

Thus, The solution of given system of equation are;

x = - 2 and y = 3

Now,

Substitute the value of x and y in all the given options and find the same solution of given system of equation as;

A: 8x + 4y = −4

17x + 2y = −28

Substitute the value of x = - 2 and y = 3;

8x + 4y = −4

8 × - 2 + 4 × 3 = - 4

- 16 + 12 = - 4

- 4 = - 4

17x + 2y = −28

17 × - 2 + 2 × 3 = - 28

- 34 + 6 = - 28

- 28 = - 28

Thus, This system of equation has same solution.

Therefore, The same solution of the given system of equations will be same as the solution of below system of equations;

⇒ 8x + 4y = −4

17x + 2y = −28

Option A is true.

Answer:

(B) π/12 + π/6 k

Step-by-step explanation:

Points of inflection are where f"(x) = 0 and changes signs.

f(x) = cos²(3x)

f(x) = (cos(3x))²

f'(x) = 2 (cos(3x))¹ × -sin(3x) × 3

f'(x) = -6 sin(3x) cos(3x)

Using double angle formula:

f'(x) = -3 sin(6x)

f"(x) = -3 cos(6x) × 6

f"(x) = -18 cos(6x)

0 = -18 cos(6x)

0 = cos(6x)

6x = π/2 + 2πk or 6x = 3π/2 + 2πk

We can simplify this to:

6x = π/2 + πk

x = π/12 + π/6 k

What is place value

Place value is the value of a digit based on its position within a numeral, especially in the base-10 (decimal) number system.

Each digit in a number has a place value, and the position of the digit determines its contribution to the overall value of the number.

The digit in the hundreds place (6) comes first. Next is the tens digit (7) then lastly the ones digit (1)

This results to 671

Step-by-step explanation:

well if its 1 to 1 that means how ever meany you have of one you will have the same exact amount of the other food

473x1 = 473x1

Final answer:

To find the number of turnips, set up a proportion using the given ratio and cross multiply to solve for the number of turnips.

Explanation:

To find the number of turnips, we can set up a proportion using the given ratio:
Number of potatoes / Number of turnips = Ratio of potatoes to turnips.
Since the ratio of potatoes to turnips is 1:1, the proportion will be:
473 / Number of turnips = 1 / 1.

To solve for the number of turnips, cross multiply:
473 * 1 = Number of turnips * 1.
Number of turnips = 473.

Therefore, there are 473 turnips in this scenario.

Answer:

6[tex]\sqrt{5}[/tex]

Step-by-step explanation:

We can factorize 180 to get 2^2*3^2*5.

We know that 2^2 and 3^2 are squares so we can remove them from under the radical.

So, the simplified square root would be 6[tex]\sqrt{5}[/tex]

To remove perfect squares inside a square root, we simplify the number using prime factorisation. In this case, √180 simplifies to 6√5.

The given value is √180. To simplify it or remove perfect squares, we have to find the prime factors of the number under the square root. We can write 180 as 2 * 2 * 3 * 3 * 5. In square root simplifications, we usually group the factors into pairs, because a pair of same factors gives one factor outside the square root. Here, 2 * 2 becomes 2 and 3 * 3 becomes 3. There is an extra 5 inside the square root that cannot come out because it doesn't have a pair. Hence, √180 simplifies to 6√5.

Answer:

4 M + 2 N = 120

Step-by-step explanation:

If we name "M" the number of tables for four people, and "N" the number of tables for two people, then the total number of people to be seated using M tables (of four people) would be the product "4 * M".

Similarly, the total number of people to be seated if the owner has N number of two person tables, would be: "2 * N".

Therefore, if the owner has M four people tables and N two person tables, the total number of people seated at the restaurant would be the addition:

4 * M + 2 * N. Since he wants this number to be 120, we complete the equation making this expression equal to 120:

4 * M + 2 * N = 120

The equation that represents this situation is 2x + 4y = 120, where x represents the number of tables for two and y represents the number of tables for four. Thus, this mathematical equation reflects the owner's seating arrangement plans for his restaurant.

Let's use x to represent the number of tables for two and y to represent the number of tables for four. Since each table for two can seat 2 people and each table for four can seat 4 people, the total number of people that can be seated is 2x + 4y. The owner of the restaurant wants to seat a total of 120 people, so the equation that represents this situation is 2x + 4y = 120.

In this equation, x and y are the variables. The x value represents the number of tables for two and the y value represents the number of tables for four.

The domain of a function is the set of all possible input values for the function. Reflecting a graph over the x-axis does not change the domain of the function.

The domain of a function is the set of all possible input values for the function. When a graph is reflected over the x-axis, the y-values are negated. In this case, since the graph is a horizontal line, the y-values remain the same after reflection. Therefore, reflecting the graph over the x-axis does not change the domain of the function. The domain will still be the same set of real numbers that satisfy the given condition, which is 0 ≤ x ≤ 20.

When a function is reflected over the x-axis, the domain remains the same and the sign of each value in the range is negated.

When a function f(x) is reflected over the x-axis to form -f(x), it affects both the domain and the range. Let's break it down step by step:

Original Function: f(x)

Domain: The set of all possible input values for x in the function f(x).

Range: The set of all possible output values for f(x).

Reflected Function: -f(x)

Reflected Domain: The domain remains the same because reflecting over the x-axis does not change the x-coordinates. So, the reflected domain is the same as the original domain.

Reflected Range: The range is affected by the reflection. All the positive values in the original range become negative, and all the negative values become positive. If the original function had points (a, b), the reflected function will have points (a, -b). This essentially flips the original range values.

In summary:

Reflected Domain: Same as the original domain.

Reflected Range: The sign of each value in the original range is negated. For example, if the original function had a point (2, 3), the reflected function would have a point (2, -3).
