Answer:

The answer assumes that the density of glass is 3 g/cm^3, not 3 g/cm^2.

The mass of the paperweight is 270 grams.

Step-by-step explanation:

Lets calculate the volume of a sphere having a radius of 3.5cm, and then divide that by 2 to get the volume of the hemisphere (half a sphere).  The sphere has a diameter of 7cm (therefore, a radius of 3.5cm).

Vol (sphere) = (4/3)πr^3

Vol = (4/3)(3.14)(3.5cm)^3

Vol = 180 cm^3

Half of this (the hemisphere) will be 90 cm^3

We know the volume, and we know the density of glass (3 g/cm^3), so multiply the two to obtain the mass of the paperweight.

 (90 cm^3)*(3g/cm^3) = 270 grams

What is percentage ?

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used.

The formula to calculate the future value of an investment is:

FV = PV * (1 + r/n)^(nt)

where:

PV = present value = $1,000

r = annual interest rate = 8.25%

n = number of compounding periods per year = 12 (monthly)

t = number of years = 3

FV = $1,000 * (1 + 0.0825/12)^(12 * 3)

Plugging in the values and using a calculator, we get:

FV = $1,000 * (1 + 0.0825/12)^(12 * 3) = $1,000 * (1.006866)^36 = $1,000 * 1.281216 = $1,281.216

So after 3 years, Beth's investment will be worth $1,281.216.

Answer:

x = -6

Step-by-step explanation:

x/15 + 3/15 = -1/5

x/15 + 1/5 = -1/5

x/15 = -2/5

x = -6

Let's check

-6/15 + 3/15 = -1/5

-3/15 = -1/5

-1/5 = -1/5

So, x = -6 is the correct answer.

The smaller side of the triangle from missing sides is 63cm.

What is a triangle?

In Geometry, triangles are the type of polygons, which have three sides and three vertices. This is a two-dimensional figure with three straight sides. A triangle is considered a 3-sided polygon. The sum of all the three angles of a triangle is equal to 180°. The triangle is contained in a single plane. Based on its sides and angle measurement, the triangle has six types.

Based on the sides of a triangle, a triangle is classified into 3 types, namely:

Scalene Triangle – All the sides are of different measures.

Isosceles Triangle – Two sides of a triangle are of the same measure and the remaining side has a different measure.

Equilateral Triangle – All the 3 sides of a triangle are of the same measure.

Based on the angles of a triangle, a triangle is classified into 3 types, namely:

Acute Angle Triangle – All the angles of a triangle is less than 90°.

Obtuse Angle Triangle – One of the angles of a triangle is greater than 90°.

Right Angle Triangle – One of the angles of a triangle is equal to 90°.

Now,

According to Pythagorean theorem,

H^2=P^2+B^2

Where H=hypotenuse, B=base, P=Perpendicular

Given base=16

let perpendicular=x then hypotenuse=x+2 as  The lengths of the other two sides are consecutive odd integers

Therefore, (x+2)^2=x^2+16^2

x^2+4+4x=256+x^2

x=63 and x+2=65

Hence,

          The smaller side of the triangle from missing sides is 63cm.

The probability that the sum of the numbers on the dice facing up add up to 3 is 1/18 and VAR(A)= 1

Probability is defined as the likeliness of an event to occur. The probability of any event to occur ranges from 0 to 1, and the sum of all the probabilities of all the events happening is 1.

probability = desired outcome / total outcomes

A 6-sided dice has numbers 1, 2, 3, 4, 5, 6 at each of the 6 sides.

The event of rolling two fair 6-sided dice, which the numbers on the dice facing up add up to 3, is by having (1, 2) or (2, 1).

probability = desired outcome / total outcomes

probability = 2 / (6 x 6)

Answer:

If you have one x2-block and 2n x-blocks, you need to add (2n)^2 1-blocks to form a square. The dimensions of the square will be (x2-block + 2n x-blocks) x (x2-block + 2n x-blocks) = (2n+2) x (2n+2) = (2n + 2)^2.

The total sound level at the point is 100 dB (10 dB x 10 speakers).

The formula for calculating the sound level emitted by each speaker is 10 * log (100 / 10) = 10 dB. This means that each speaker emits a sound level of 10 dB.

To calculate this, we first need to understand the principle of the logarithmic addition of sound levels. The logarithmic addition of sound levels states that when two sound waves with different amplitudes overlap, the resulting amplitude is the sum of the logarithms of the individual amplitudes.

For example, let's say we have two sound waves with amplitudes of 10 dB and 20 dB. The resulting amplitude will be 10 * log (10 + 20) = 10 * log (30) = 10 dB + 20 dB = 30 dB.

Therefore, in our example, the 10 speakers each emit a sound level of 10 dB. This means that when all 10 speakers play simultaneously, the total sound level at the point is 100 dB (10 dB x 10 speakers).

Using the exterior angle theorem, [tex]112+x=164 \implies x=52[/tex]

C(x) = 16x – 63, where x is the number of thousands of bottles, gives the cost of producing bottled spring water.

The formula R(x) = - x2 + 326x – 7463 calculates the total amount (revenue) from the sale of these bottles.

Bottles sold will yield the highest profit.

Profit maximization

Profit after selling 245 thousand bottles

C(x) = 16x – 63

R(x) = – x² + 326x – 7463.

Revenue – Cost = Profit

P(x) = R(x) – C (x)

= – x² + 326x – 7463 – (16x – 63) (16x – 63)

= – x² + 310x – 7400

Choice c)

Profit = x2 minus 310x minus 7400

P(x) = – x² + 310x – 7400

P’(x) = -2x + 310

P’(x) = 0 => -2x + 310 = 0 => x = 155

P’’(x) = - 2 < 0

As a result, profit is greatest at x = 155.

The highest profit will be generated if 155 bottles are sold.

Alternative b)

Profit maximization at x = 155

P(x) = – x² + 310x – 7400

The highest possible profit is Rs 16625.
