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:

her total is $140

Step-by-step explanation:

turn 12% into a decimal (0.12) then multiply that by the amount she paid (125*0.12) that gives you 15. then add 15 to 125 to get the total amount ($140)

hope this helps!

Answer:

$140

Step-by-step explanation:

The total before the 12% tip is $125

To find 12% of $125, we will change 12% to a decimal, 0.12

0.12 * 125=15

15$ is the tip.

125+15=140

$140 is her total

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:

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

[tex]75[/tex] cubic inches

Step-by-step explanation:

Given:

The base of each pyramid is a square with a side length of 5 inches

Height of of pyramid is 9 inches.

To find: volume of the pyramid

Solution:

As the base of each pyramid is a square with a side length of 5 inches,

length of the pyramid (l) = base of the pyramid (b) = 5 inches

Height of of pyramid (h) = 9 inches

Volume of the pyramid [tex](V)=\frac{lbh}{3}[/tex]

On putting values of l, b and h, we get

[tex]V=\frac{5\times 5\times 9}{3}=75[/tex] cubic inches

The TV is 27 inches tall.

Step-by-step explanation:

Given,

The diagonal length of the TV = 45 in

The width of the TV = 36 in

To find the length the the TV.

Formula

By Pythagoras theorem,

h²=l²+b², where h be hypotenuse, b be base and l be height.

Now,

Putting, h=45, b= 36 we get,

45²=l²+36²

or, l²= 45²-36²

or, l²= 729

or, l = √729

or, l = 27

Hence,

The TV is 27 in tall.

To solve for the area, find the area of an entire theoretical parallelogram. Then subtract the difference (the small triangle added).

Area = 1020 centimeters squared

If you need the answer in square feet, you have to convert.

(1 cm)^2 = (0.3937008 inches)^2

1 cm ^2 ≅0.155 in ^ 2 (or square inches)

A = 1020 * 0.155 ≅ 158.1 square inches

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

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.
