I got the answer right on my quiz

The following statements are true:

- To begin converting the equation to standard form, subtract 36 from both sides.

- To complete the square for the x terms, add 4 to both sides.

- The center of the circle is at (-2, 3).

- The radius of the circle is 7 units.

A circle is a two-dimensional figure with a radius and circumference of 2pir.

The area of a circle is πr².

We have,

To convert the equation to standard form, we need to complete the square for both the x and y terms.

x² + y² + 4x - 6y - 36 = 0

x² + 4x + y² - 6y = 36

(x² + 4x + 4) + (y² - 6y + 9) = 49

(x + 2)² + (y - 3)² = 7²

So the center of the circle is at (-2, 3) and the radius of the circle is 7 units.

Therefore, the following statements are true:

- To begin converting the equation to standard form, subtract 36 from both sides.

- To complete the square for the x terms, add 4 to both sides.

- The center of the circle is at (-2, 3).

- The radius of the circle is 7 units.

And,

The statement "The center of the circle is at (4.-6)" is false, and the statement "The radius of the circle is 49 units" is also false.

Thus,

The following statements are true:

- To begin converting the equation to standard form, subtract 36 from both sides.

- To complete the square for the x terms, add 4 to both sides.

- The center of the circle is at (-2, 3).

- The radius of the circle is 7 units.

Answer:

a

Step-by-step explanation:

Answer:

Step-by-step explanation:

No of sample space , n(s) = 12 + 11 + 17 + 5 = 45

No of favorable cases , n(e) = 17

Probability of getting blue marble ,

P(e) = n(e)/n(s)

        = 17 / 45

NOW

Probability of not getting blue marble,

P'(e) = 1 - p(e)

       = 1 - 17 / 45

      = ( 45 - 17)/45

     = 28 / 45

Hope it helped :)

The required probability of not getting blue marble is 28/45.

Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

Given that bag holds 12 red marbles, 11 green marbles, 17 blue marbles, and 5 yellow marbles.

The total number of outcomes. = 12 + 11 + 17 + 5

So n(S) = 45

Number  of favorable outcomes, n(E) = 17

Probability of getting blue marble,

⇒ P(E) = n(E)/n(S)

⇒ P(E) = 17/45

So the required probability of not getting blue marble as

⇒ P'(E) = 1 - P(E)

⇒ P'(E) = 1 - 17 / 45

⇒ P'(E) = (45 - 17)/45

⇒ P'(E) = 28/45

Hence, the required probability of not getting blue marble is 28/45.

Answer:

Therefore 0.006 inches of rain will have fallen after 2 minutes.

Step-by-step explanation:

Given that,

y = 0.003x

where y is the number of inches of rain after x minutes.

To find the number of inches of rain after 2 minutes, we plug x = 2 minutes in above model equation.

∴ y= 0.003×2

     =0.006

Therefore 0.006 inches of rain will have fallen after 2 minutes.

After 2 minutes, 0.006 inches of rain will have fallen based on the equation y = 0.003x. This calculation involves substituting x with 2 and multiplying by 0.003.

To determine how many inches of rain will fall after 2 minutes using the given equation y=0.003x, we substitute x with 2.

So, the number of inches of rain that will have fallen after 2 minutes is 0.006 inches.

495 students in 7th grade do not ride a car to school

Step-by-step explanation:

Number of students walking or riding a bike = 8

Number of students who ride a car = 15

Number of students who take the bus = 25

Total students in the sample = 48

⇒ Percentage of students who rides a car in the sample = 15/48 × 100 = 31.25%

Total number of students = 720

Number of students who ride a car = 31.25/100 × 720

                                                           = 225

Number of students who do not ride a car to school = 720 - 225 = 495

[tex]log_3_2(5)=\frac{1}{5} k[/tex]

Step-by-step explanation:

Let's start by using change of base property:

[tex]log_b(x)=\frac{log_a(x)}{log_a(b)}[/tex]

So, for [tex]log_2(5)[/tex]

[tex]log_2(5)=k=\frac{log(5)}{log(2)}\hspace{10}(1)[/tex]

Now, using change of base for [tex]log_3_2(5)[/tex]

[tex]log_3_2(5)=\frac{log(5)}{log(32)}[/tex]

You can express [tex]32[/tex] as:

[tex]2^5[/tex]

Using reduction of power property:

[tex]log_z(x^y)=ylog_z(x)[/tex]

[tex]log(32)=log(2^5)=5log(2)[/tex]

Therefore:

[tex]log_3_2(5)=\frac{log(5)}{5*log(2)}=\frac{1}{5} \frac{log(5)}{log(2)}\hspace{10}(2)[/tex]

As you can see the only difference between (1) and (2) is the coefficient [tex]\frac{1}{5}[/tex] :

So:

[tex]\frac{log(5)}{log(2)} =k\\[/tex]

[tex]log_3_2(5)=\frac{1}{5} \frac{log(5)}{log(2)} =\frac{1}{5} k[/tex]

Step-by-step explanation:

The correct answer is C) 68 units². The net to compute the surface area of the three-dimensional figure is C) 68 units².

To compute the surface area of a three-dimensional figure, one must consider all the faces that make up the shape. The net of a three-dimensional figure provides a two-dimensional representation of all these faces. By calculating the area of each face and summing them up, we can find the total surface area.

Let's assume the net provided shows a figure composed of rectangles and triangles. We will calculate the area of each face as follows:

1. For rectangles, the area is given by the formula A = length × width.

2. For triangles, the area is given by the formula A = 1/2  × base × height.

Let's denote the lengths of the sides of the rectangles as l and w, and the base and height of the triangles as b and h, respectively.

Now, let's calculate the area of each face:

- Rectangle 1: A1 = l ×  w

- Rectangle 2: A2 = l ×  w (assuming it has the same dimensions as Rectangle 1)

- Triangle 1: A3 = 1/2 × b × h

- Triangle 2: A4 = 1/2 ×  b ×  h (assuming it has the same dimensions as Triangle 1)

The total surface area (SA) is the sum of the areas of all faces:

SA = A1 + A2 + A3 + A4

SA = (l × w) + (l ×  w) + (1/2 × b ×  h) + (1/2×  b ×  h)

SA = 2lw + bh

SA= 2*5*3+19*2

SA=68

After performing these calculations with the given measurements from the net, we would find that the total surface area is 68 units².

Therefore, the correct answer is C) 68 units²."

Step-by-step explanation:

Please refer to the attached image for explanations

The two angles are 29 degrees and 61 degrees. The steps involve setting up and solving a simple equation based on the definition of complementary angles.

To solve this question we first need to know that complementary angles add up to 90 degrees. Let's assume the measure of one angle is X. Since the other angle is 32 degrees more than the first, we represent it as X + 32.

Following the principle of complementary angles, we can set up an equation: X + (X + 32) = 90, simplifying gives 2X + 32 = 90.

Subtracting 32 from both sides we get: 2X = 58. Finally, if we divide each side by 2 we get X = 29 degrees. Therefore, one angle measures 29 degrees and the other, which is 32 degrees more, measures 61 degrees.

Answer:

Step-by-step explanation:

This is correct for all right angle because Pythagoras theorem has proved that for a right-angle triangle, the square of the hypotenuse length is equal to the sum of the square of the opposite side and square of the adjacent sides

c² = a² + b²

This is true because the squares formed a right angle triangle from their arrangements.

So, let proved with the formula

Let assume one square = 1 unit

A 3 by 3 Square

Length = 3

A 4 by 4 Square

L = 4

A 5 by 5 Square. Hypotenuse

L = 5

a² + b² = c²

3² + 4² = 5²

9 + 16 = 25

25 = 25

Step-by-step explanation:

Final answer:

To find the volume of a cone with specific dimensions, use the formula V = 1/3 π r² h. Substitute the given values for radius and height, then calculate the volume rounded to the nearest tenth.

Explanation:

The volume of a right circular cone can be found using the formula V = 1/3 × π × r² × h, where r is the radius and h is the height of the cone.

Plugging in the values (r = 9.6 cm, h = 19.9 cm) gives V = 1/3 × 3.142 × 9.62 × 19.9 = 200.5 cm³

Answer:

Headband: 15.98 in.

Wristband: 8.63 in.

Step-by-step explanation:

In this problem, we call:

h = the amount of fabric used for each headband

w = the amount of fabric used for each wristband

We are told that:

Sean uses 671.16 in at on headbands for 39 players and three coaches, so the total number of headbands made is 42

Therefore, we can write

[tex]671.16 = 42 h[/tex]

And solving for h, we find

[tex]h=\frac{671.16}{42}=15.98 in.[/tex]

Then we also know that Sean uses 336.57 in the fabric on wristbands just for the players, so he produced 39 wristbands; so we can write:

[tex]336.57 = 39w[/tex]

And solving for w,

[tex]w=\frac{336.57}{39}=8.63 in.[/tex]
