Step-by-step explanation:

1 milk = 1 3/4 cup of flour

1 flour = 3/7 cup of cocoa powder

4 cups of milk = 1 3/4 x 4 = 7/4 x 4/1 = 7 cups of flour

7 cups of flour = 7 x 3/7 =  7/1 x 3/7 = 3 cups of cocoa powder

Kenneth needs 3 cups of cocoa powder for the chocolate cakes he is making with 4 cups of milk.

To find out how many cups of cocoa powder Kenneth needs for his chocolate cakes, we should first determine how much flour is necessary for 4 cups of milk and then how much cocoa powder is needed for that amount of flour. Kenneth uses one and 3/4 cups of flour for each cup of milk. So for 4 cups of milk, he needs:

1 ¾ cups of flour/cup of milk x 4 cups of milk = 7 cups of flour

Next, for every cup of flour, Kenneth needs 3/7 cup of cocoa powder. Therefore, to find out the total cups of cocoa powder for 7 cups of flour, the calculation is:

3/7 cups of cocoa powder/cup of flour x 7 cups of flour = 3 cups of cocoa powder

So Kenneth needs a total of 3 cups of cocoa powder for his cakes.

To change the story from first person to third person point of view, first-person pronouns like 'I', 'me', and 'we' should be changed to third-person pronouns such as 'they', 'he', 'she', or the friends' names.

To change the point of view of the story from first person to third person, it is necessary to change the pronouns used in the narration. If the original story used first-person pronouns such as I, me, and we, these would need to be changed to third-person pronouns such as they, he, she, or the friends' names to reflect the third person point of view.

For example, a sentence that originally reads "We went to the park after school" would change to "They went to the park after school" in the third person point of view. This shift enables the story to be told as if an outside observer is describing the events that happen to the group of friends, rather than the friends themselves narrating the story.

Answer:

The correct option is A.

Step-by-step explanation:

The given inequality is

[tex]y\leq -2x[/tex]

The sign of inequality is ≤, it means the points on relation line lie in the solution set.

The related equation of the inequality is

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

At x=0,

[tex]y=-2(0)=0[/tex]

At x=1,

[tex]y=-2(1)=-2[/tex]

Plot the points (0,0) and (1,-2) on a coordinate plane.

The sign of inequality is ≤, it means we have shade below the line.

The point (-2,4) and (3,-6) are in solution set because,

[tex]4\leq -2(2)\Rightarrow 4\leq 4[/tex]            (True)

[tex]-6\leq -2(3)\Rightarrow -6\leq -6[/tex]           (True)

Therefore option A is correct.

The points (1,2) and (1,3) are not in the solution set because,

[tex]2\leq -2(1)\Rightarrow 2\leq -2[/tex]            (False)

[tex]3\leq -2(1)\Rightarrow 3\leq -2[/tex]           (False)

Therefore options B,C and D are incorrect.

Answer:  (1,2) (-2,-4)

Step-by-step explanation:

Answer:

The answer is C (4,-3)

Step-by-step explanation:

When you reflect over the x axis that means you flip the image to the opposite side over the x (horizontal) line. So if the first line is (4,3) then the reflection is (4,-3)

Answer:

Option A is correct.

d = 50t shows the relationship between d and t

Step-by-step explanation:

Point slope form: For a point [tex](x_1, y_1)[/tex] and a slope m, the equation of the line can be written as

[tex]y-y_1=m(x-x_1)[/tex] ......[1], where m is the slope of the line.

Here, d represents the total distance ( in miles) and t represents the time (in hours).

From the given table:

Consider any two points (1, 50) and (2, 100).

Calculate slope:

Slope(m) =  [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

               = [tex]\frac{100-50}{2-1}=\frac{50}{1} =50[/tex]

⇒[tex]m= 50[/tex]

Now, by point slope intercept form:

Substitute  m= 50 and (1, 50) in [1]

we have;

[tex]y -50 = 50(x-1)[/tex]

Using distributive property: [tex]a\cdot(b+c) = a\cdot b+ a\cdot c[/tex]

y -50 = 50x -50

Add both sides 50 we get;

y -50+ 50= 50x -50 + 50

Simplify:

[tex]y =50x[/tex]

∵y = d represents the distance and x = t represents the time;

then, our equation become:

[tex]d = 50t[/tex]

The equation representing the relationship between the distance covered (d) and time (t) in the given situation is d = 50t. This signifies that the distance covered is equal to 50 times the time.

In the given data, we observe that the total distance (d) travelled by the car in an hour is always 50 miles. This means that every hour, the car covers a distance of 50 miles.

Therefore, the relationship between the distance covered (d) and time (t) can represent this situation is d = 50t.

This signifies that 'd', the distance covered, is equal to 50 times 't', the time in hours. For example, when t=1 hour, d = 50*1 = 50 miles. Similarly, when t=2 hours, d = 50*2 = 100 miles. This continues accordingly.

Answer:

Correct choice is D (In a whole pepperoni pizza are 660 calories, in  in a whole ham and pineapple pizza are 580 calories).

Step-by-step explanation:

Let x calories be the number of calories a whole pepperoni pizza contains and y calories be the number of calories a whole ham and pineapple pizza contains.

1. If half a pepperoni pizza plus three fourths of a ham and pineapple pizza contains 765 calories, then

[tex]\dfrac{1}{2}x+\dfrac{3}{4}y=765.[/tex]

2. If 1/4 of a pepperoni pizza plus a whole ham and pineapple pizza contains 745 calories. then

[tex]\dfrac{1}{4}x+y=745.[/tex]

3. Multiply each equation by 4 and get a system of two equations:

[tex]\left\{\begin{array}{l}2x+3y=3060\\x+4y=2980\end{array}\right.[/tex]

From the second equation [tex]x=2980-4y[/tex], then

[tex]2(2980-4y)+3y=3060,\\ \\5960-8y+3y=3060,\\ \\-8y+3y=3060-5960,\\ \\-5y=-2900,\\ \\y=580.[/tex]

Then

[tex]x=2980-4\cdot 580=2980-2320=660.[/tex]

The whole pepperoni pizza contains 660 calories and the whole ham and pineapple pizza contains 580 calories. These values are obtained using a system of two equations obtained from the given statements.

Let's denote 'P' as the calories in a whole pepperoni pizza, and 'H' as the calories in a whole ham and pineapple pizza. We can then interpret the problem as two equations based on the given information.

First equation (from the first sentence in the question): 0.5P + 0.75H = 765.

Second equation (from the second sentence in the question): 0.25P + H = 745.

Now we just need to solve this system of equations. Multiply the second equation by two to match the 'P' terms in both equations: 0.5P + 2H = 1490.

Subtract the first equation from this new equation: 0.5P + 2H - (0.5P + 0.75H)= 1490 - 765. This simplifies to: 1.25H = 725, meaning H = 580 calories.

We can then substitute H = 580 into the first original equation to solve for P: 0.5P + 0.75*580 = 765. Solving this gives P = 660 calories.

So, a whole pepperoni pizza contains 660 calories, and a whole ham and pineapple pizza contains 580 calories. This corresponds to the option d) in the given list.

Answer: Variant A

Step-by-step explanation:

The range of a function is the set of y-values the function contains. Thus, in this case, the range would be the set of values under the y column, as this represents the y-values the function produces.

We see "2, 3, 4, 2" under the y column. Since we are establishing a set of values, we are going include all the values under the column, which includes 2, 3, and 4. We are not going to repeat the second 2 because it isn't necessary, as 2 is already in the set thus.

Thus, the final set for the range of the function is {2, 3, 4}, or Choice A.

Answer:

The correct answer is B) x equals quantity of 2 plus or minus 2i square root of 2 all over 3.

Step-by-step explanation:

We are given the following quadratic equation:

[tex]-3x^2-4x-4 = 0[/tex]

Since, it cannot be factorized so we will use the quadratic formula:

x = [tex]\frac{-b+-\sqrt{b^2-4ac} }{2a}[/tex]

Substituting in the values of a, b and c in the above formula to get:

x = [tex]\frac{-(-4)+-\sqrt{(-4)^2}-4(-3)(-4) }{2(-3)}[/tex]

x = [tex]-\frac{2}{3} +i \frac{2\sqrt{2} }{3}[/tex], x = [tex]-\frac{2}{3} -i \frac{2\sqrt{2} }{3}[/tex]

Therefore, the correct answer option is B) x equals quantity of 2 plus or minus 2i square root of 2 all over 3.

When adding like terms, they simply add together:

6y + 3y = 9y

The rule of adding two powers are as follows:

[tex]y^{4}  + y^{4} = y^{4 + 4} = y^{8}[/tex]

So 6y⁴ + 3y⁴ = 9y⁸

Answer:

Moira's solution is..... incorrect

6y4+3y4 is the same as...... (6*y^4) + (3*y^4)

Answer:

Area of the floor of the classroom is 72 inch².

Step-by-step explanation:

We are given the dimensions of the rectangular floor as,

Length = 36 feet and Width = 32 feet

Since, the scale drawing have the length = 9 inches

This gives, the ratio of the actual length to the scale drawing length = [tex]\frac{36}{9}[/tex]

Thus, we have,

[tex]\frac{36}{9}=\frac{32}{x}[/tex], where x is the width in the scale drawing.

So, on solving,

[tex]x=\frac{32\times 9}{36}[/tex] i.e. x= 8 inches

Since, Area of the rectangle= Length × Width

Thus, area of the rectangular floor = 9 × 8 = 72 inch².

Thus, the area of the floor of the classroom is 72 inch².

The area of the floor of the scale drawing and the scale factor are 72 in² and 1/4 respectively

The scale factor = 9 / 36 = 1/4

The length of the model canbe calculated thus :

Model width = 32 × 1/4 = 8 inches

The Area of a rectangle can be calculated using the relation :

Area of floor = 8 inches × 9 inches = 72 inch²

Therefore, the area of the floor of the scale drawing is 72 in²

Final answer:

The equation given to calculate the distance between the trains is D = |262.5 - 120T|. To find the values of T for which D = 50, substitute 50 for D in the equation and solve for T. By solving the equations, we find that T is approximately 1.8 and 2.6.

Explanation:

The equation given to calculate the distance between the trains is D = |262.5 - 120T|, where T is the time after Train B departs. To find the values of T for which D = 50, substitute 50 for D in the equation and solve for T.

50 = |262.5 - 120T|

To remove the absolute value, we can split the equation into two cases:

Solving these equations will give us the values of T for which D = 50.

By solving both equations, we find that T is approximately 1.8 and 2.6, so the answer is A) 1.8 and 2.6.
