The sum of 0.47 and 0.2 is 0.67

From the question, we are to determine the sum of the given decimal numbers.

The numbers are 0.47 and 0.2

In the first model, we have 4 tenths and 7 hundredths

and

In the second model, we have 2 tenths and 0 hundredths

Adding the tenths

4 tenths + 2 tenths = 6 tenths

Adding the hundredths

7 hundredths + 0 hundredths = 7 hundredth

Putting the results together, we get

6 tenths and 7 hundredths

That is,

0.67

Hence, the sum of 0.47 and 0.2 is 0.67

The amount at the end of three years is 1.06 times the initial amount.

Rate = 2%

Time = 3 Years

Let the principal amount be P

Simple interest = P * R * T

SI = ( P * 2 * 3 ) / 100

= 6P/100

= 0.06P

Amount = P + SI

= P + 0.06P

= P(1 + 0.06)

= 1.06P

The amount at the end of three years is 1.06 times the initial amount.

The quadrant in which the angle theta as described in the task content is located is; Quadrant II.

It follows from the task content that the angle theta described has; it's tan value to be negative and it's sine value to be positive.

Hence, since only sine of angles is positive in quadrant II while tan and cosine values are negative, it follows that the quadrant where theta is located is; Quadrant II.

Step-by-step explanation:

The value of V-E+F=2

Euler's polyhedron formula, V−E+F=2

A hexagonal prism has 8 faces, F=8

A hexagonal prism has 12 vertices, V=12

A hexagonal prism has 18 edges, E=18

So, 12−18+8=2

V-E+F=2 is Euler's polyhedron formula.

F=8 for a hexagonal prism with 8 faces

V=12 is the number of vertices in a hexagonal prism.

E=18 is the number of edges on a hexagonal prism.

So, 12−18+8=2

A hexagonal prism is a three-dimensional prism with two parallel ends that have the same size and form. The hexagonal prism has six parallelogram-shaped faces on its six sides. Regular hexagonal prisms and irregular hexagonal prisms are the two types of hexagonal prisms. A hexagonal prism is a polyhedron with 8 faces, 18 edges, and 12 vertices, with 6 faces in the shape of rectangles and 2 faces in the shape of hexagons.

Answer:

  thousands place: 4th one to the left of the decimal point, 1000.

Step-by-step explanation:

You want the number place of a 1 that has a value 100 times that of the 1 in 314.

The digit 1 in the number 314 is in the "tens place." It signifies 1 ten is part of the value of the number 314.

The value of a digit 1 that is 100 times that will be ...

  10 × 100 = 1000

That is, the digit will be found in the "thousands place," two digits to the left of the location in the number 314.

The 1 with a value of 1000 is written in the thousands place, the 4th place to the left of the decimal point.

The area of the original fountain was 16π square yards at the Palace of Versailles due to the radius of the fountain on a scale of 1 : 4.

The area of the circle is equal to the product of the square of the radius of the circle and pi.

A = πr²

where 'r' is the radius of the circle

The radius of the fountain using a scale of 1 : 4 in New York

The area of the fountain in New York is 1,600π square yards.

To determine the area of the original fountain at the Palace of Versailles

We can write this as a ratio as

A₁ : A₂ =  πr² :  π(4r)²

A₁ : 1,600π  =  πr² :  π(4r)²

A₁ / 1,600π  =  πr² /  π(4r)²

A₁  =  (πr²/ π 16r²)(1,600π )

A₁  = 1,600π/16

A₁  = 16π square yards

Therefore, the area of the original fountain was 16π square yards at the Palace of Versailles.

The required value of x would be 13 because the complementary angles are a pairing of angles in addition to 90°.

The complementary angles are defined as when pairing of angles addition to 90° then they are called complementary angles. There are two types of supplementary angles.

We have been given the figure from the right angle.

To determine the value for x

As per the complementary angles property,

⇒ 3x +25 + 2x = 90

Solve for x,

⇒ 5x = 90 - 25

⇒ 5x = 65

⇒ x = 65/5

⇒ x = 13

The area of a triangle with the given base and height is 4 1/6 square inches.

Given that, the base of a triangle is 1 2/3 inches and the height of a triangle is 5 inches.

The area of a triangle is defined as the total space occupied by the three sides of a triangle in a 2-dimensional plane. The basic formula for the area of a triangle is equal to half the product of its base and height, i.e., A = 1/2 × b × h.

Now, the mixed fraction 1 2/3 can be written as 5/3

The area of the triangle=1/2 × 5/3 × 5

To multiply the fractions multiply the numerators of the fraction and write the product in the numerator and multiply the denominators of the fractions and write the product in the denominators.

That is, (1/2 × 5/3) × 5/1

=5/6 × 5/1

=25/6

=4 1/6

So, the area of a triangle with a base of 5/3 inches and height 5 inches is 4 1/6 square inches.

Step-by-step explanation:

from triangle 1:

59+45+∠a = 180

∠a = 180-59-45 = 76

∠a+44+∠b = 180

∠b = 180-∠a-44 =  180-76-44 = 60

[tex]\textsf{d)} \quad \dfrac{5}{6}, \quad \dfrac{25}{6}[/tex]

Step-by-step explanation:

Given:

[tex]12 \cos \left(\dfrac{2 \pi}{5}x\right)+10=16, \quad \textsf{when}\; \left(\dfrac{2 \pi}{5}x\right)\; \textsf{is in radians}.[/tex]

Subtract 10 from both sides of the given equation:

[tex]\implies 12 \cos \left(\dfrac{2 \pi}{5}x\right)=6[/tex]

Divide both sides of the equation by 12:

[tex]\implies \cos \left(\dfrac{2 \pi}{5}x\right)=\dfrac{1}{2}[/tex]

Take the inverse of cosine of both sides:

[tex]\implies \dfrac{2 \pi}{5}x = \cos^{-1}\left(\dfrac{1}{2}\right)[/tex]

[tex]\implies \dfrac{2 \pi}{5}x =\dfrac{\pi}{3}+2 \pi n, \dfrac{5 \pi}{3}+2 \pi n[/tex]

Multiply both sides by 5:

[tex]\implies 2 \pi x=\dfrac{5 \pi}{3}+10 \pi n, \dfrac{25 \pi}{3}+10 \pi n[/tex]

Divide both sides by 2π:

[tex]\implies x=\dfrac{5 \pi}{6 \pi}+\dfrac{10 \pi}{2 \pi}n, \dfrac{25 \pi}{6 \pi}+\dfrac{10 \pi}{2 \pi}[/tex]

Simplify:

[tex]\implies x=\dfrac{5}{6}+5n, \dfrac{25}{6}+5n[/tex]
