The numbers as a single digit times a power of ten are ; 1. 4x10^-9, 2. 4x10^10, 3. 5x10^7, 4. 2x10^-5

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division. The Numbers constants, variables, operations, brackets can all be represented by mathematical symbol; which can also be used to indicate the logical syntax's order of operations and other features.

Therefore, each number as a single digit times a power of ten.

1. 0.000000043 is [tex]4 \times 10^{-9}[/tex]

2. 43560000.000 is[tex]4 \times 10^{10}[/tex]

3. 56.234567  is [tex]5 \times 10^7[/tex]

4. 0.00002346 is [tex]2 \times 10^{-5}[/tex]

Hence, The numbers as a single digit times a power of ten are ; 1. 4x10^-9, 2. 4x10^10, 3. 5x10^7, 4. 2x10^-5

The given area presented on the coordinate plane has dimensions

given by the lengths of the line joining the vertices.

Response:

The given figure can be taken as a composite figure of wo triangles and

a trapezium.

Area of the triangle at the top, A₁ = 0.5 × 4.5 × 1 = 2.25

Area of the trapezoid, A₂ = 0.5 × (6 + 4.5) × 1 = 5.25

Area of the bottom triangle, A₃ = 0.5 × 2 × 6 = 6

Therefore;

Area of the figure, A = A₁ + A₂ + A₃

Which gives;

A = 2.25 + 5.25 + 6 = 13.5

Answer:

yes i don't know that so.....

Answer:

Step-by-step explanation:

total mass of people = 50× 5 = 250kg

height = 20m

force = mass × g = 250× 10 ( taking g= 10m/s²)

work done = force × distance

Step-by-step explanation:

Given:

Length of a box is 9 inches, width is 2 inches and height is 1.5 inches.

The cost of silver coating is $2.50 per sq. inches.

To find:

The total cost of silver coating for the box.

Solution:

The total surface area of a cuboid is

[tex]A=2(lb+bh+hl)[/tex]

Where, l is length, b is breadth and h is height.

Putting [tex]l=9,b=2,h=1.5[/tex], we get

[tex]A=2(9\times 2+2\times 1.5+1.5\times 9)[/tex]

[tex]A=2(18+3+13.5)[/tex]

[tex]A=2(34.5)[/tex]

[tex]A=69[/tex]

So, the total surface area of the box is 69 square inches.

Cost of silver coating is $2.50 per sq. inches. So, the cost of silver coating for the box is

[tex]Cost=69\times 2.50[/tex]

[tex]Cost=172.50[/tex]

Therefore, the cost of silver coating for the box is $172.50.

Answer:

Perimeter of the dilated rectangle = 23.2 m

Step-by-step explanation:

If a point is dilated by a scale factor = k

Coordinates of the image point after dilation will follow the rule,

(x, y) → (kx, ky)

From the given rule,

(x, y) → (0.4x, 0.4y)

Which reveals that the figure has been dilated by a scale factor = 0.4

Length of the rectangle = 12 m

Width of the rectangle = 17 m

If the given rectangle is dilated by a scale factor of 0.4,

Length of the image rectangle = 12 × 0.4 = 4.8 m

Width of the image rectangle = 17 × 0.4 = 6.8 m

Perimeter of a rectangle = 2(length + width)

Therefore, perimeter of the image rectangle = 2(4.8 + 6.8)

                                                                           = 23.2 m

Answer:

452.16

Step-by-step explanation:

i got it right on test

The surface area of the cylinder is,

⇒ TSA = 452.16 cm²

We have to given that;

Height of cylinder = 6 cm

And, Diameter of cylinder = 12 cm

Hence, We get;

⇒ Radius of cylinder = 12 / 2 = 6 cm

We know that;

The formula for the total surface area of a given cylinder whose radius is r and height is h is,

TSA = 2πr (h + r)

Hence, We get;

TSA = 2πr (h + r)

TSA = 2 × 3.14 × 6 (6 + 6)

TSA = 37.68 × 12

TSA = 452.16 cm²

Thus, The surface area of the cylinder is,

⇒ TSA = 452.16 cm²

Answer:

52% Copper, 28% Zinc, 20% Nickel

Step-by-step explanation:

Copper is 13 out of 13+7+5 = 25

13/25 = 52%

Zinc is 7 out of 25 so 28%

Nickel is 5/25 = 20%

Answer:

6

Step-by-step explanation:

Let x = number of hours.

Let y = cost.

The fixed cost is $11.

The cost per hour is $2.

For x hours, the cost per hour is 2x.

y = 2x + 11

23 = 2x + 11

12 = 2x

x = 6
