A block of cheese has a volume of 187 cm3 and a mass of 140 g.
What is the density of the cheese in g/cm3 rounded to 2 decimal places?

Answer:

Part a) The Labeled part of the Can ⇒ 263.76 cm^2

Part b) The Surface Area of the Can is ⇒ 340.69 cm^2

Part c) The Volume of the Can is ⇒  38.465 * 12 = 461.58 cm^2

Step-by-step explanation:

~ If the dimensions of this can is 12 centimeters by 7 centimeters... ~

Part a)

1. Now a can is in the shape of a cylinder, thus the Base would act as a circle. That being said, 7 centimeters acts as the diameter of this circle.

2. If we were to unravel the middle of the can, it would be that this circular portion turns out of be a rectangle, with dimensions of the height of the cylinder, by the circumference of the Base of the cylinder. The circumference can be calculated by πd where d is the diameter ⇒ 3.14 * 7 ⇒ 21.98 cm. Thus the dimensions of this middle part of the can is 21.98 by 12 ⇒ 21.98 * 12 ⇒ 263.76 cm^2.

The Labeled part of the Can ⇒ 263.76 cm^2

Part b)

1. We know previously, that 7 centimeters acts as the diameter of this circle, so the radius must be half of that, which is 7/2 ⇒ 3.5 cm. Now we can apply the area of a circle formula πr^2 where r ⇒ radius, such that: 3.14 * ( 3.5 )^2 ⇒ 3.14 * 12.25 ⇒ 38.465 cm^2.

2. Knowing that the Base of this can is 38.465 cm^2, multiply this value by 2 to get the surface area of the two bases, provided they are equivalent: 38.465 * 2 ⇒ 76.93 cm^2

3. We know that this labeled section of the can is ⇒ 263.76 cm^2. This means that The Surface Area of the Can is ⇒ 263.76 + 76.93 = 340.69 cm^2

Part c )

The volume of the can is calculated by Base * height. We know from the previous questions that the Base ⇒ 38.465, and the height was given to be 12 centimeters. This means that The Volume of the Can is ⇒  38.465 * 12 = 461.58 cm^2

1. You can see there are 36 outcomes when rolling the dice.

2. Then you find that there are 11 possible outcomes with at least one 6. (For example 1-6 2-6 3-6.)

3. The chance of rolling at least one 6 in a pair of dice is 11/36.

4. 11 divided by 36 is 0.3055555.

Answer:

The polynomial is irreducible.

Step-by-step explanation:

The polynomial 3p²-15pq+20q² can be factored as (p-2q)(3p-10q).

Factorization, also known as factoring, is the breakdown of one element into a product of other objects, or factors, which when multiplied together generate the original. For example, the number 21 factors into primes as 3 × 7, and the polynomial x² − 9 factors as (x+3)(x-3).

The polynomial is given as follows:

3p²-15pq+20q²

It is required to find the factorization of the given polynomial.

The greatest common factor (GCF) of the coefficients (3, -15, 20), is 3.

Rewrite the polynomial using the GCF of 3. We get:

3(p²-5pq+6q²)

We need to find two numbers that multiply to 6q² and add to -5pq.

The numbers are -2q and -3p.

Combine the factored quadratic expression with the GCF of 3.

3(p-2q)(p-3q)

Therefore, the correct factorization of the polynomial 3p²-15pq+20q² is 3(p-2q)(p-3q).

Answer:

Mr. Smith should pay the department store $32.00 plus $2.36 in sales tax for a total bill of $34.36.

Step-by-step explanation:

The department store was adding sales tax to the bill. Sales tax is a tax on goods and services purchased and is normally a certain percentage added to the buyer's cost.

Solution: 2.36 ÷ $32.00 = 0.0735. Sales tax was charged by the department store at a rate of 7.375%.

Answer: Mr. Smith should pay the department store $32.00 plus $2.36 in sales tax for a total bill of $34.36.

Sales tax rates vary from state to state. Retail sales tax rates are set by the individual states in the United States and vary from 0 to 9% of the sales price. Sales tax is usually the responsibility of the merchant to collect and submit to the state, and stated separately (or implicitly added at the time of the sale) to consumers.

The additional amount Mr. Smith paid is tax.

The amount was determined by calculating 7.4% of the items bought.

Mr Smith. should pay $34.36.

Tax is an amount of money levied by the government or an agency of the government on certain goods and services. Taxes increases the price of a good or service.

In order to determine the tax paid, divide the additional amount paid by the total cost of items purchased.

(2.36 / $32) x 100 = 7.4%

Answer:

[tex]\theta = 12.16^0.[/tex]

Step-by-step explanation:

Given,

Height = 12.6 m

Object distance from the person = 58.5 m

Angle of depression

[tex]tan \theta = \dfrac{P}{B}[/tex]

[tex]tan \theta = \dfrac{12.6}{58.5}[/tex]

[tex]tan \theta = 0.2154[/tex]

[tex]\theta = 12.16^0[/tex]

Hence, angle of depression is equal to [tex]\theta = 12.16^0.[/tex]

The angle of depression of the person's line of sight to the object on the ground is 12.15°.

The information forms a right angle triangle. The person eyes above the ground is the opposite side of the triangle. The object distance from the building in line of the sight is the adjacent side of the right angle triangle.

Therefore,

using trigonometric ratio,

tan Ф = opposite /adjacent

tan Ф = 12.6 / 58.5

tan Ф = 0.21538461538

Ф = tan⁻¹ 0.21538461538

Ф = 12.1549416972

Ф = 12.15°

angle of depression  ≈ 12.15°

Answer:

B y = 3x^2 + 12x + 19

Step-by-step explanation:

y = 3(x + 2)^2 + 7

To expand the square of the binomial,

either recall that (a + b)^2 = a^2 + 2ab + b^2, or use FOIL.

y = 3(x^2 + 4x + 4) + 7

y = 3x^2 + 12x + 12 + 7

y = 3x^2 + 12x + 19

Answer: B y = 3x^2 + 12x + 19

Final answer:

After expanding and simplifying the given function, we find that the equivalent function is y = 3x^2 + 12x + 19, which corresponds to option B.

Explanation:

The task is to find the equivalent function to y = 3(x + 2)2 + 7. We'll start by expanding the square and then distributing the 3 across the resultant terms.

First, expand the square: (x + 2)2 = x2 + 4x + 4.

Next, distribute the 3: 3(x2 + 4x + 4) = 3x2 + 12x + 12.

Finally, add the 7 to complete the expansion: 3x2 + 12x + 12 + 7 = 3x2 + 12x + 19.

Therefore, the equivalent function is B y = 3x2 + 12x + 19.

The number of different ways ten students can line up for lunch is 3,628,800, which is found by calculating the factorial of 10 (10!).

The question asks how many different ways ten students can line up for lunch. This is a problem of calculating permutations without repetition, as each student is unique and once a student takes a place in line, they cannot be in another position at the same time. The formula to calculate the number of permutations for 'n' unique items is n! (n factorial), which is defined as the product of all positive integers from 1 to n.

In this case, 'n' is 10 because there are 10 students. Therefore, the calculation is 10! =  3,628,800 different ways.

Answer:

70

Step-by-step explanation:

It is made with a combination. Combination of 4 taken from 8, the formula of the combination is as follows:

nCr = n! / (r! * (n-r)!)

In this case 8 is "n" and 4 is "r"

8C4 = 8! / (4! * (8-4))!

8C4 = 8! / (4! * 4!)

8C4 = 40320/576

8C4 = 70

In this way he obtained the answer that is 70

Final answer:

A regular hexagon will coincide with itself when rotated by angles of 60 degrees, or multiples of it like 120, 180, 240, 300, and 360 degrees, because these are the angles of rotational symmetry for a hexagon.

Explanation:

A regular hexagon has six sides of equal length and interior angles that are also equal. When a regular hexagon is rotated about its center, there are specific degree measures for which it will fit exactly onto itself, known as the angles of rotational symmetry. Since a full rotation measures 360 degrees and a hexagon has six sides, we can divide 360 degrees by the number of sides to find the smallest angle of rotation that will carry the regular hexagon onto itself.

The calculation is 360 ÷ 6 = 60 degrees. Therefore, a regular hexagon will coincide with itself every 60-degree turn. Other angles that will carry the hexagon onto itself are multiples of 60 degrees: 120 degrees, 180 degrees, 240 degrees, 300 degrees, and 360 degrees (a full rotation).

Where H is the height of the cube,  W is the width of the cube and L is the length of the cube

We have been that the dimensions of a cube are as:

The length of the cube (L) = 5 cm

The height of the cube (H) = 5 cm

The width of the cube (W) = 5 cm

d = √ (L² + W² + H² )

d = √ (5² + 5² + 5² )
