Answer:

The radius of the circle is √74

Step-by-step explanation:

Radius of a circle is the distance between the centre of a circle and its circumference.

The origin of the circle (0,0) will be its centre.

The point on the edge of the circle is the point on its circumference which is (5,7).

The radius of the circle will be the distance between this two points according to definition.

R = √(x2-x1)²+(y2-y1)²

Given (x1, y1) = (0,0) and (x2, y2) = (5, 7)

x1 = 0, y1 = 0, x2 = 5, y2 = 7

Substituting into the formula we have;

R = √(5-0)²+(7-0)²

R = √5²+7²

R = √25+49

R = √74

Answer:

Step-by-step explanation:

Given that a centre has an origin (0,0) and (5,7) at the edge.

What is the radius of the circle

This is a direct question, we can apply coordinate geometry by finding the distance between two point, .

From co-ordinate geometry, the distance between two points is

d =√[(x2-x1)² + (y2-y1)²]

So, applying this

Point 1 = (x1,y1) = (0,0)

Point 2 = (x2,y2) = (5,7)

The radius of the is

r = √[(x2-x1)² + (y2-y1)²]

r = √[(5-0)² + (7-0)²]

r = √[5² + 7²]

r = √(25 + 49)

r = √74

The correct answer is D

Answer:

1/25

Step-by-step explanation:

The probability is 1/25 because 10 red marbles plus 15 green marbles = 25 marbles in total. Therefore, the probability  of choosing a red marble without looking is 1/25.

Answer:

The probability that Yuki will pull out a red marble is [tex]\( \frac{2}{5} \)[/tex].

Explanation:

To find the probability of selecting a red marble, you divide the number of red marbles by the total number of marbles in the bag.

Given:

- Number of red marbles = 10

- Number of green marbles = 15

Total number of marbles = Number of red marbles + Number of green marbles

Total number of marbles = 10 + 15 = 25

Now, to find the probability of selecting a red marble:

[tex]\[ \text{Probability} = \frac{\text{Number of red marbles}}{\text{Total number of marbles}} \][/tex]

[tex]\[ \text{Probability} = \frac{10}{25} \][/tex]

[tex]\[ \text{Probability} = \frac{2}{5} \][/tex]

Answer:

D

Step-by-step explanation:

We can set up a proportion because the "expected" amount should correspond to the sample amount.

[tex]\frac{24}{80} =\frac{x}{720}[/tex], where x is the number of dinner entrees that are fish

Cross-multiply:

80 * x = 24 * 720

80x = 17280

Divide both sides by 80:

x = 17280/80 = 216

The answer is D.

Hope this helps!

Answer:

D. 216

Step-by-step explanation:

Entrees : fish

80 : 24

720 : X

X/720 = 24/80

X = 720 × 24/80

X = 216

Answer:

616 cm²

Step-by-step explanation:

To find the area of a circle you use the formula A = π · r²

So we know that the diameter is 28 cm, to find the radius we would divide this in half, because d = 2r, giving us 14. Now we can do 14² which is 196, and then times that by pi or in this case 22/7.

196 × (22/7) = 616

Answer:

616 square centimeters

Step-by-step explanation:

Diameter of circle = 28 centimeters

π = 22/7

Area of a circle, A = π [tex]\frac{D^{2} }{4}[/tex]

A =  [tex]\frac{22}{7}[/tex] * [tex]\frac{28^{2} }{4}[/tex]

A =  [tex]\frac{22}{7^{1} }[/tex] * [tex]\frac{(4 * 7)^{2} }{4}[/tex]

A =  [tex]\frac{22}{7^{1} }[/tex] *  [tex]\frac{4^{2} *7^{2} }{4}[/tex]

A = 22 * 28

A = 616 square centimeters

The real square roots of -121 are ±11i, where 'i' represents the imaginary unit.

When dealing with square roots of negative numbers, it's important to recognize that the square root of a negative number is an imaginary number. In this case, the square root of -121 is found by taking the square root of the positive value of 121 and then multiplying the result by 'i'. The square root of 121 is 11, so the square root of -121 becomes ±11i.

In the context of real numbers, square roots of negative values do not exist. However, in the realm of complex numbers, the introduction of the imaginary unit 'i' allows for the representation of square roots of negative numbers. The number 'i' is defined as the square root of -1. When squared, 'i' multiplied by itself yields -1.

Hence, the square root of -121, which is a negative number, results in ±11i, representing two imaginary numbers with opposite signs. These imaginary square roots are crucial in various fields, including mathematics, physics, and engineering, where complex numbers play a significant role in modeling and solving problems involving quantities with both real and imaginary components.

Answer:

5.) Answer choice C (44%)

7.) Answer choice A (47%)

Step-by-step explanation:

to find the percentage, we find the total of all women and divide the total of women from candidate A from the total amount of women voters.

1346+1704 = 3050

1346/3050 ≈ 44%

The same procedure applies for question 7 except we add EVERYONE up. We divide the amount of men for candidate B from all of the voters.

1704+1488+1346+1871 = 6409

1488/6409 ≈ 23%

Answer:146

Step-by-step explanation:

The measure of the arc DEB is equivalent to 146°.

An angle is formed when two rays have the same end point. The common end point is called vertex.

Given is to find the measure of arc DEB.

We can write the measure of angle DBE as half the measure of arc BCD. Mathematically, we can write -

∠DBE = 1/2(arc BCD)

107 = 1/2(arc BCD)

arc BCD = 107 x 2

arc BCD = 214°

Now, we can write -

m(arc DEB) + m(arc BCD) = 360°

m(arc DEB) = 360 - 214

m(arc DEB) = 146°

Therefore, the measure of the arc DEB is equivalent to 146°.

Answer:

Sample response: Volume represents the amount of space an object takes up. Surface area represents the area of the outside surface of the object. If you need to find the amount of space something takes up, or the amount to fill something, find the volume. If you want to find how much is needed to cover something, find the surface area.

Step-by-step explanation:

If they are asking for volume, they are wanting to know how much can go inside the object....If they are asking for surface area.....the are wanting to know about the outside only.

The volume is equal to the product of area and height of shape.

The total area occupied by the surfaces of an object is called its surface area.

"A volume is simply defined as the amount of space occupied by any three-dimensional solid. These solids can be a cube, a cuboid, a cone, a cylinder or a sphere."

"The total area occupied by the surfaces of an object is called its surface area."

Different shapes have different volumes. In 3d geometry, we have studied the various shapes and solids such as cube, cuboid, cylinder, cone, etc., that are defined in three dimensions. For all these shapes, we are going to learn to find the volume.

The formula to calculate the volume of a solid in a three-dimensional space, is to find the product of dimensions. Basically, the volume is equal to the product of area and height of shape.

Volume =  Base Area x Height

For shapes having flat surfaces such as cube and cuboid, it is easy to find the volume. But for curved shapes like cone, cylinder and sphere, we have to consider the dimensions of its curved surface as well, such as radius or diameter.

In geometry, different 3D shapes have different surface areas which can be easily calculated using the formulas that we will be learning in this article. The surface area is classified into two categories:

1. Lateral surface area or Curved surface area

2. Total surface area

There is a different surface area formula for every geometrical shape, but the idea behind all is to get the total area occupied by all the faces of the objects.

The total surface area considers all the faces of the 3D shape including the flat surfaces and the curved surfaces, while the lateral surface area is calculated to find the area occupied by the curved surface of the shape. It does not include the area of the bases. A sphere is one 3D figure which has only one round surface with no flat base.
