Answer:

A. Point

Step-by-step explanation:

A point is infinitely small and comprised of a single location.

hope this helps!! p.s. i really need brainliest :)

The object that is infinitely small among the option is a point. Option A is correct.

All over the world, most things are in use as of common quantity, so people all over the world agree that they have to follow a common system of measurement and that the common system of measurement is called standard measurement.

Here,
The object that is infinitely small among the option is a point. Because there is no instrument that can measure the point. Since a point is nothing but a demonized dot. While line, ray, or plane are infinitely long and their measure can be possible.

Thus, the object that is infinitely small among the option is a point. Option A is correct.

Answer:

The discount is 22.50 and the final price $52.50

Step-by-step explanation:

Discount = Original Price x Discount %/100

Discount = 75 × 30/100

Discount = 75 x 0.3

You save = $22.50

Final Price = Original Price - Discount

Final Price = 75 - 22.5

Final Price = $52.50

Answer:

41

Step-by-step explanation:

For this, you have to make two equations;

One that calculates the amount of coins

and one that calculates the amount of R

I'm going to set

R2 = x

R5 = y

To make this a bit easier to look at

So to do the number of coins, you want to do this:

x + y = 114

This is saying that the total amount of R2 coins plus the total amount of R5 coins will add up to 114

Then, you want to calculate the worth of them.

2(x) + 5(y) = 351

This is saying that for ever R2 coin there is, it will increase the total by 2, and every R5, it will increase the total by 5. When you add these together, it will come out to 351.

Then you have to solve the system of equations:

x + y = 114

2x + 5y = 351

-2 * (x + y = 114)

2x + 5y = 351

-2x + -2y = -228

2x + 5y = 351

3y = 123

y = 41

Since y is the amount of R5 coins, we know we have 41 R5 coins.

So the answer is

41

Answer:

The answer to this equation is 2

Step-by-step explanation:

x-2 = 3(2-x) \4

x-2= 6 -3x/4

cross multiply

4(x-2)= 6-3x

4x-8 = 6-3

collect like terms

4x+3x = 6+8

7x = 14

divide both sides by 7

7x/7= 14/7

x = 2

Answer:

(7, -1)

Step-by-step explanation:

Let's remember our key words:

Down/up means to translate the y axis.

Right/left means to translate the x axis.

Now that we know what to do, let's look at our equation.

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

A point located at (5, 3) is translated down 4 units and right 2 units.

Let's work on the x axis first.

It says that you are translating to the right. That means your value is going higher, so you go to the right 2. 5+2=7

So now that we have our x, (7), let's rewrite our equation. (7, 3)

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

Next, let's do y.

The points are translating down. That means our value will lessen.

Since we are going down on our y axis by 4, we will subtract our current y coordinate with 4. 3-4=-1.

Now we know our y, so let's rewrite our equation with our new y. (7, -1).

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

Our final coordinates are (7, -1).

The length of the arc shown in red is

Step-by-step explanation:

step 1

Find the circumference of the circle The circumference is equal to we have substitute

step 2

Find the length of the arc in red Remember that the length of the circumference subtends a central angle of 360 degrees so by proportion find the length of the arc by a central angle of 110 degrees Simplify

Answer:

Explanation:

⇒ m∠2 = 130°

Then,

⇒ m∠4 = 130° ( vertically opposite angles )

m∠1  + m∠2  + m∠3  + m∠4 = 360°

2(m∠1) = 360° - 130° * 2

⇒ m∠1 = 50°

⇒ m∠3 = 50°

Answer:

m∠1 = 50°

m∠3 = 50°

m∠4 = 130°

Step-by-step explanation:

Vertical Angle Theorem:  When two straight lines intersect, the opposite vertical angles formed are always equal (congruent) to each other.

⇒ m∠1 = m∠3   and   m∠2 = m∠4 = 130°

Linear pair:  Two adjacent angles which sum to 180°.

⇒ m∠1 + m∠2 = 180°

⇒ m∠3 + m∠4 = 180°

⇒ m∠1 + m∠130° = 180°

⇒ m∠1 = 50°

As m∠1 = m∠3 then m∠3 = 50° also

AE || BC

===》 DCB angle = DAE angle

AC /

__________________________________

Thus :

DCB angle = x

And also we know that the submission of interior angles of any triangle must equals to 180 degrees so :

In BCD triangle :

B + C + D = 180

x + x + D = 180

D = 180 - 2x

__________________________________

In the other hand we know that :

BDC angle + BDA angle = 180

because they make a straight line together so ;

180 - 2x + 50 = 180

- 2x = 180 - 230

- 2x = - 50

x = 25
