Answers

Answer 1

Answer:

-8 degrees

Step-by-step explanation

Half of negative 16 would be negative 8.

Answer 2

Answer:

-8

Step-by-step explanation:

-16 ÷ 2 = -8

You could also do:

16 ÷ 2 = 8

and then put a negative in front of 8

And to prove it's true,

8 x 2 = 16

-8 x 2 = -16

Answers

Answer is 8g^15
Pls mark me brainliest

Answer:

Your answer should be 8g^15

Step-by-step explanation:

If cubed (power of 3) is on a parenthesis, that means you have to cube every expression inside that parenthesis. In order to distribute exponents, mutliply them. This gives you g^5 times ^3, which is g^15. ^3 has to also be distributed to the 2, which is 2^3 = 8. 8 and g^15 is 8g^15.

C. 4.2 pounds Brand A. 0.8 pounds Brand B
D. 2.3 pounds Brand A. 2.7 pounds Brand B

Answers

Answer:

C. 4.2 pounds Brand A. 0.8 pounds Brand B

Step-by-step explanation:

How much of each brand of coffee is needed to make 5 pounds that will cost

$6.75/pound?

Let the number of pounds for Brand A = x

Let the number of pounds for Brand B = y

Brand A coffee sells for $7/pound, while Brand B sells for $5.40/pound.

$7 × x + $5.40 × y = $6.75 × 5

7x + 5.40y = 33.75.......Equation 1

x + y = 5 .......Equation 2

x = 5 - y

7(5 - y)+ 5.40y = 33.75

35 - 7y + 5.40y = 33.75

35 - 33.75 = 7y - 5.40y

= 1.25 = 1.6y

y = 1.25/1.6

y = 0.78125 pounds.

Approximately to the nearest whole number, Brand B = 0.8 pounds.

x = 5 - y

x = 5 - 0.8 pounds

x = 4.2 pounds

Brand A = 4.2 pounds

Step-by-step explanation:

have an amazing day luv

Answer:

10 students would pay for lunch with $30.

Step-by-step explanation:

This is how I know $30 is the correct answer:

1. To figure out how much money it would cost for 1 student I would take the $12 the four students paid for lunch and divide it by 4 so we would know the exact cost for one students lunch (12/4=3 or $3)

2. Now we know $3 is the cost for 1 student. We can now multiply the $3 by 10 (students) so we can get the cost for 10 lunches (3(10)=30 or $30)

3. We got our final answer of $30=10 students lunches.

I hope this helps:)

A square has a perimeter of 51.6 inches. What is the length of each side?
13 inches
129 inches
12.9 inches
1.29 inches

Answers

Answer:

12.9

Step-by-step explanation:

A square has even lengths on each side. Since there is 4 sides on a square. We divide perimeter by 4.

51.6/4 = 12.9 inches

The length of each side of the square is 12.9 inches if perimeter of square is 51.6 inches.

What is Quadrilateral?

A quadrilateral is defined as a two-dimensional shape with four sides, four vertices, and four angles.

The perimeter of a square is the sum of the lengths of all its sides.

Let a be the length of each side of the square, then the perimeter P is given by:

P = 4a

We are given that the perimeter is 51.6 inches, so we can set up the equation:

51.6 = 4a

Solving for a, we divide both sides by 4:

a = 51.6/4

a = 12.9

Therefore, the length of each side of the square is 12.9 inches if perimeter of square is 51.6 inches.

cy-5=-3d+6y for y. Only on solution

Answers

Answer:

This is the answer for your question. I hope it helps you!!!! Pls Mark as the brainliest answer!!!

Step-by-step explanation:

Simplifying

Cy + -5 = -3d + 6y

Reorder the terms:

-5 + yC = -3d + 6y

Solving

-5 + yC = -3d + 6y

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-6y' to each side of the equation.

-5 + -6y + yC = -3d + 6y + -6y

Combine like terms: 6y + -6y = 0

-5 + -6y + yC = -3d + 0

-5 + -6y + yC = -3d

Add '5' to each side of the equation.

-5 + -6y + 5 + yC = 5 + -3d

Reorder the terms:

-5 + 5 + -6y + yC = 5 + -3d

Combine like terms: -5 + 5 = 0

0 + -6y + yC = 5 + -3d

-6y + yC = 5 + -3d

Reorder the terms:

-5 + 3d + -6y + yC = 5 + -3d + -5 + 3d

Reorder the terms:

-5 + 3d + -6y + yC = 5 + -5 + -3d + 3d

Combine like terms: 5 + -5 = 0

-5 + 3d + -6y + yC = 0 + -3d + 3d

-5 + 3d + -6y + yC = -3d + 3d

Combine like terms: -3d + 3d = 0

-5 + 3d + -6y + yC = 0

Answers

Answer:

Y = (0, 3)

Step-by-step explanation:

Notice that the first the transformation is a rotation of 90 degrees around the origin, and then a reflection around the x axis.

If a reflection around the x axis resulted in (3, 0)  that means the point was already on the x axis.

Then in order for a rotation in 90 degrees to take the point Y to (3, 0), Y must have been on the y-axis as (0, 3)

What is the slope of a line that is perpendicular to the line 3y - 4x = -8?

Answers

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

[tex]3y - 4x = - 8[/tex]

Add sides 4x

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

[tex]3y = 4x - 8[/tex]

Divide sides by 3

[tex] \frac{3}{3} y = \frac{4}{3} x - \frac{8}{3} \\ [/tex]

[tex]y = \frac{4}{3} x - 8 \\ [/tex]

This is the slope-intercept form of the line.

We that the coefficient of the x in slope-intercept form , is the slope of the line.

Thus ;

[tex]slope = \frac{4}{3} \\ [/tex]

_________________________________

Remember from now on ;

Multiply of the slopes of the lines which are perpendicular to each other equal -1 .

Suppose the slope of the line which question asked is m.

So :

[tex] \frac{3}{4} \times m = - 1 \\ [/tex]

Multiply sides by 4

[tex]4 \times \frac{3}{4} \times m = 4 \times ( - 1) \\ [/tex]

[tex]3m = - 4[/tex]

Divide sides by 3

[tex] \frac{3}{3} m = \frac{ - 4}{3} \\ [/tex]

[tex]m = - \frac{4}{3} \\ [/tex]

choose a linear function for the line representing by the point slope equation y-5=3(x-2)

Answers

multiply 3x and -2 by 3 and add 5 to right side of equal sign to get y = -1

Answer:

y=3x-1

Step-by-step explanation:

To find the linear function you first need to put the equation into standard slope intercept form which is y=mx+b. m represents the slope and b represents where the line intercepts the y axis.

To figure it out you need to solve for y.

y-5=3(x-2)

Expand 3(x-2) to 3x-6.

y-5=3x-6

Isolate the y by adding 5 to both sides, giving you y=3x-1.

The slope is 3 and the Y intercept is -1.

Which example shows the Socratic teaching method Plato recorded?A. Yes, Polemarchus, - Thrasymachus said . . . .B. Yes, said Cleitophon, interposing, . . . .C. I am only repeating what you are saying, . . . .D. To be sure, he replied, they are liable to err.The Republic by PlatoPlato was a student of the Greek philosopher, Socrates. He recorded many conversations between Socrates and the men of Athens in the 5th century A.D. These conversations often took a form that has come to be known as the Socratic Method, as Socrates asked questions and added examples to lead his companions to draw correct conclusions about such concepts as virtue, beauty, friendship, truth, and justice. In the following passage from The Republic, the topic is justice.Great or small, never mind about that: we must first enquire whether what you are saying is the truth. Now we are both agreed that justice is interest of some sort, but you go on to say 'of the stronger'; about this addition I am not so sure, and must therefore consider further.Proceed.I will; and first tell me, Do you admit that it is just for subjects to obey their rulers?I do.But are the rulers of states absolutely infallible, or are they sometimes liable to err?To be sure, he replied, they are liable to err.Then in making their laws they may sometimes make them rightly, and sometimes not? True.When they make them rightly, they make them agreeably to their interest; when they are mistaken, contrary to their interest; you admit that?Yes.And the laws which they make must be obeyed by their subjects, and that is what you call justice?Doubtless.Then justice, according to your argument, is not only obedience to the interest of the stronger but the reverse?What is that you are saying? he asked.I am only repeating what you are saying, I believe. But let us consider: Have we not admitted that the rulers may be mistaken about their own interest in what they command, and also that to obey them is justice? Has not that been admitted?Yes.Then you must also have acknowledged justice not to be for the interest of the stronger, when the rulers unintentionally command things to be done which are to their own injury. For if, as you say, justice is the obedience which the subject renders to their commands, in that case, O wisest of men, is there any escape from the conclusion that the weaker are commanded to do, not what is for the interest, but what is for the injury of the stronger?Nothing can be clearer, Socrates, said Polemarchus.Yes, said Cleitophon, interposing, if you are allowed to be his witness.But there is not need of any witness, said Polemarchus, for Thrasymachus himself acknowledges that rulers may sometimes command what is not for their own interest, and that for subjects to obey them is justice.Yes, Polemarchus, - Thrasymachus said that for subjects to do what was commanded by their rulers is just.Yes, Cleitophon, but he also said that justice is the interest of the stronger, and, while admitting both these propositions, he further acknowledged that the stronger may command the weaker who are his subjects to do what is not for his own interest; whence follows that justice is the injury quite as much as the interest of the stronger.But, said Cleitophon, he meant by the interest of the stronger what the stronger thought to be his interest, this was what the weaker had to do; and this was affirmed by him to be justice.Those were not his words, rejoined Polemarchus.Never mind, I replied, if he now says that they are, let us accept his statement. Tell me, Thrasymachus, I said, did you mean by justice what the stronger thought to be his interest, whether really so or not?Certainly not, he said. Do you suppose that I call him who is mistaken the stronger at the time when he is mistaken?Yes, I said, my impression was that you did so, when you admitted that the ruler was not infallible but might be sometimes mistaken.
