Answer:

centre = (0, 0 ), radius = 5

Step-by-step explanation:

The equation of a circle centred at the origin is

x² + y² = r² ( r is the radius )

x² + y² = 25 ← is in this form

with centre = (0, 0 ) and r = [tex]\sqrt{25}[/tex] = 5

Answer:

y = x/2

Step-by-step explanation:

Let y represent the number the number of red balls and let x represent the number of blue balls. Since we have that the number of Red balls is half the number of the Blue ones, and the number of red balls equals x, we divide x by 2. So, x/2.

Since x/2 is equal to the number of blue balls and y is the number of blue balls, we write y = x/2.

So, our linear equation in two variables that represents "the statement the number of Red balls is half the number of the Blue ones"​ is

y = x/2

Respuesta:

200 mangos

Explicación paso a paso:

Dado :

Sea el número inicial de mangos = x

Primera venta:

3 / 5x + 2

Número a la izquierda = x - (3 / 5x + 2) = 2 / 5x - 2

Segunda venta:

1/3 (2 / 5x - 2) + 2 = 2 / 15x - 2/3 + 2

Cantidad restante:

2 / 5x - 2 - (2 / 15x - 2/3 +2)

2 / 5x - 2 - 2 / 15x + 2/3 - 2

0,2666666x - 3,3333

Tercera venta:

1/2 (0,2666666x - 3,3333) + 1 = 0,133333x - 1,666665 + 1

0.2666666x - 3.3333 - (0.133333x - 1.666665 + 1) = venta final

0,2666666x - 3,3333 - (0,133333x - 1,666665 + 1) = 24

0,2666666x - 3,3333 - 0,133333x + 1,666665 - 1 = 24

0,133333x - 2,666635 = 24

0.133333x = 24 + 2.666635

0,133333x = 26,666635

x = 26,666635 / 0,133333

x = 200.00026

x = 200 mangos

Answer:

75.06239187

Step-by-step explanation:

1/2bh= Area of a Triangle

6^2+b^2=8.5^2 because we are missing a side we need to use the pythagorean theorem.

36+b^2=72.25

b^2=36.25

b=6.02

6.02+19= base

25.02

Now area

1/2bh

1/2 (25.02*6)

25.02*6= 150.1247

150.1247/2= 75.06239187 is Area

The above decimals before area are rounded.

Answer:

There are 680 buttons altogether

Step-by-step explanation:

Here, we want to get the total number of buttons

From the question, the ratio of number of red to white buttons is 4:7

mathematically, this mean;

r:w = 4:7 = ?/280

thus;

4/7 = ?/280

7 * ? = 280 * 4

? = (280 * 4)/7

? = 40 * 4 = 160

From here, we can see that the number of white buttons is 160

from the second part of the question,

b:r = 3:2 = ?:160

3/2 = ?/160

2 * ? = 160 * 3

? = 480/2

? = 240

Thus, we have the sum total of the number of buttons as;

240 + 280 + 160 = 680

Step-by-step explanation:

iknow

Answer:

C

Step-by-step explanation:

the vertex of the blue is (-4,1)

the matching formula has the vertex in it (h,k)

y = (x-h)^2 + k

notice in the formula h is negative

so since the x value of the vertex is (-4), you make it positive in the formula

the y value is positive in the formula and so is the y value of the vertex (1)

Answer:

0

Step-by-step explanation:

When a number is not included or used, it can be considered 0.

This makes sense, because if it had a actualy value, it would effect the polynomial, and change the answer.

The only time it would  not effect the polynomial is when it 0.

Hope this makes sense :D

Answer:

16

Step-by-step explanation:

the greatest common factor of 16 and 48 is 16

Factors for 16: 1, 2, 4, 8, and 16.

Factors for 48: 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48.

Answer: sqrt(2)/2  which is choice D

======================================================

Explanation

(3pi/4) radians converts to 135 degrees after multiplying by the conversion factor (180/pi).

The angle 135 degrees is in quadrant 2. We subtract the angle 135 from 180 to find the reference angle

180-135 = 45

Then you can use a 45-45-90 triangle to determine that the ratio of opposite over hypotenuse is sqrt(2)/2

sine is positive in quadrant 2

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

Alternatively, you can use a unit circle. Refer to the diagram below. In red, I've circled the angle 3pi/4 radians. The terminal point for this angle has a y coordinate of sqrt(2)/2

Recall that y = sin(theta).

Answer:

x =6

Step-by-step explanation:

The angles are alternate interior angles and alternate interior angles are equal

7x = x+36

Subtract x from each side

7x -x = x+36-x

6x = 36

Divide by 6

6x/6 = 36/6

x = 6

Answer:

Step-by-step explanation:

Answer:

b = - 5 , - 7 , 5 , 7

Step-by-step explanation:

Standard quadratic equation is of the form :

ax² + b x + c , where b = p + q and c = pq

Where p and q are factors of c.

Therefore , we will consider the factors of 6.

Factors of 6 = ( -1 , -6 ) , ( -2 , -3 ) , ( 1, 6 ) , ( 2 , 3)

x² + bx + 6

b = p + q

So, b = - 7 , -5, 7 , 5

Answer:

The answer is D

Step-by-step explanation:

This is because it cant be 13 or any smaller, and if the shorter side is 13 than it can't be any less than double itself, so it's D

Answer:

A)4

Step-by-step explanation:

degree measure of the 4 angles of a trapezoid is 360

so

since we have only 2 angles, 360/2

180=125+(14x-1)

180-125=125+(14x-1)-125

55=14x-1

55+1=14x-1+1

56=14x

4=x or x=4

hope this helps!

Answer:

x = 4

Step-by-step explanation:

The interior angles of a parallelogram always add up to 360 degrees.

We already know that one of the angles is 125 degrees, so we can subtract 125 from 360, leaving us with 235.

The angle right across from the 125 angle is congruent to it and so now we can subtract another 125 from 235, leaving us with 110 degrees.

There are 2 angles left, they are both the same measurement, so we can divide 110 by 2, leaving us with 55.

This means that 14x - 1 = 55

Time to find x

First, we are going to add 1 to both sides in order to cancel it out.

14x - 1 + 1 = 55 + 1

14x = 56

Now, we are going to divide both sides by 14 in order to cancel it out.

14/14 x = 56/14

x = 4

Hope this helps!

Step-by-step explanation:

On Thursday, it would be -7°

I hope this helped♡

The integer showing temperature on Thursday is -7° C

An integer is a number with no decimal or fractional part, and it includes negative and positive numbers, including zero.

Given that, On Wednesday, the temperature was 27° above zero. On Thursday, it was 7° below zero.

Since, below zero, it starts negative numbers,

And, the temperature on Thursday was 7° below zero.

Therefore, the temperature on Thursday was -7° C

Hence, the integer showing temperature on Thursday is -7° C

Step-by-step explanation:

Answer:

PQ' : Q'Q = 3 : 1

Step-by-step explanation:

As Given In Question

We Have A Triangle With Side PQ=8cm

PQ' = 3/4 * PQ

PQ' = 3/4 * 8

PQ' = 6 cm

& Q'Q = PQ - PQ'  

            = 8 - 6 = 2cm

so the line segment PQ is divided into PQ' : Q'Q = 3 : 1
