An iron ball has a density of 4 g/cm3.
The volume of the ball is 15 cm3.
What is the mass of the ball?

Answers

Answer 1
Answer:  60 grams

========================================================

Explanation:

m = mass

v = volume

d = density

The formula we use is

d = m/v

Multiplying both sides by v allows us to solve for m

d = m/v

d*v = m

m = d*v

Now plug in the given density (d = 4) and the given volume (v = 15) and simplify:

m = d*v

m = 4*15

m = 60 grams

Note how,

d = m/v

d = 60/15

d = 4

which helps confirm our answer

The solution of this trigonometric identity is [tex]\theta = 56.310^{\circ} \pm 180\cdot i ^{\circ}[/tex], [tex]\forall \,i\in \mathbb{N}_{O}[/tex].

Step-by-step explanation:

Let [tex]7\cdot \tan \theta - 8 = 5\cdot \tan \theta -5[/tex], we proceed to simplify the expression and solve afterwards either by algebraic or by trigonometric means:

[tex]7\cdot \tan \theta -8 = 5\cdot \tan \theta -5[/tex]

[tex]2\cdot \tan \theta = 3[/tex]

[tex]\tan \theta = \frac{3}{2}[/tex]

[tex]\theta = \tan^{-1} \frac{3}{2}[/tex]

The tangent is a trigonometric function with a period of 180°. Hence, we find that the family of angles associated with such value is:

[tex]\theta = 56.310^{\circ} \pm 180\cdot i ^{\circ}[/tex], [tex]\forall \,i\in \mathbb{N}_{O}[/tex]

A park has a triangular sandbox. Todd wants to create a smaller sandbox at his backyard having the same angles as the park sandbox. Drawings of both sandboxes are shown. 18 ft 20 Park Sandbox 8+ Todd's Sandbox What is the perimeter, in feet (ft), of Todd's sandbox?​

Answers

Answer:

the perimeter is

104/5 feet or 20 4/5 ft

Step-by-step explanation:

The perimeter is a loop that surrounds, circumscribes, nor defines a two-dimensional shape and a one length.

Perimeter Calculation:

A park's sandbox measures [tex]20 \ \text ft[/tex] in diameter at its base.

Todd's sandbox has a [tex]4 \ \text ft[/tex] base.

Now [tex]\frac{4}{20}=\frac{1}{5}\\\\[/tex]

As a result, the scale factor for smaller sandboxes is [tex]\ \frac{1}{5}\\\\[/tex]

[tex]\to 14 \times \frac{1}{5} = 2.8\\\\\to 18 \times \frac{1}{5}= 3.6\\\\[/tex]

As a result, in Todd's sandbox, the missing lengths (in feet) are 2.8 and 3.6.

Todd's sandbox has a perimeter of [tex]4 + 2.8 + 3.6 = 10.4[/tex] feet.

Always remember that the sum of all angles is 180°.

PLEASE HELP The diameter D of a sphere is 19 m. Calculate the sphere's surface area A.
Use the value 3.14 for at, and round your answer to the nearest tenth.

Answers

Answer:

A = 1,133.5 m³

Step-by-step explanation:

Surface area of a sphere, A = 4πr²

π = 3.14

Radius, r = diameter / 2

= 19 m / 2

= 9.5 m

Surface area of a sphere, A = 4πr²

A = 4 * 3.14 * (9.5)²

= 4 * 3.14 * 90.25

= 1,133.54

A = 1,133.54 m³

To the nearest tenth

A = 1,133.5 m³

Michelle invests $1000 at a bank offering 3% compounded quarterly.

Answers

Answer:

A = 1000(1 + .03 /4)4t

Explanation:

The money invested is the principal that is $ 1000.

The quarterly interest = 3/4 = 0.75 %

Assuming the number of years the money invested was x, then the interest period (n) will be 4 x (quarters)

Using the formula, A = P (1 + r/100)∧n

Therefore, the growth of the investment will be given by

1000( 1.0075)∧n, where n is the interest period.

Whats the area of the rectangle?

I dont need an explanation just the simplified answer

Answers

Answer:

The area of rectangle is "31 units²".

Step-by-step explanation:

The given values are:

Length of rectangle,

= [tex]\frac{21}{7}[/tex]

Width of rectangle,

= [tex]\frac{31}{3}[/tex]

As we know,

The area of rectangle is:

=  [tex]Length\times width[/tex]

On substituting the values, we get

=  [tex]\frac{21}{7}\times \frac{31}{3}[/tex]

=  [tex]\frac{217}{7}[/tex]

=  [tex]31 \ units^2[/tex]

What is the relationship between the number of sides of the base of a prism and the number of lateral faces? The number of sides of the base of a prism is less than the number of lateral faces. The number of sides of the base of a prism and the number of lateral faces is equal. The number of sides of the base of a prism is greater than the number of lateral faces. There is no consistent relationship between the number of sides of the base of a prism and the number of lateral faces.

Answers

Answer:

Every prism has as many faces, and edges, as its base has sides. Thus, a prism with an octagonal (eight sided) base has eight lateral faces, and eight lateral edges. Each lateral face meets two other lateral faces, as well as the two bases. As a consequence, each lateral face is a four sided polygon.

The number of sides of the base of a prism and the number of lateral faces is equal.

What is a prism?

A prism is a three-dimensional object with two congruent and parallel faces, called the bases and it encloses the space between the bases. Every cross-section parallel to the base of a prism is congruent to its base.

How do we solve the given question?

In the question, we are asked to tell the relationship between the number of sides of the base of a prism and the number of lateral faces.

We let the number of sides of the base of the prism be s, and let the number of lateral faces of the prism be f.

We know that a prism has two parallel and congruent bases and every corresponding side of the base are connected by a pane. These planes are the lateral faces of the prisms. As each corresponding pair of sides is connected by one lateral face, the number of the lateral face is equal to the number of sides of the base.

∴ The number of sides of the base = The number of lateral faces of the prism

or, s = f.

∴ We can say that the number of sides of the base of a prism and the number of lateral faces are equal.
