Answer:

x = 70

Step-by-step explanation:

180* (n-2)

180*(6-2)

180*(4) = 720

102 + 146 + 120 + 124 + 158 = 650

720 - 650 = 70

A polygon is a planar figure characterized by a limited number of straight-line segments. The value of the x is 70°.

A polygon is a planar figure characterized by a limited number of straight-line segments joined to create a closed polygonal chain in geometry. A polygon is defined as a bounded planar region, a bounding circuit, or both.

The sum of the interior angles of a n-sided polygon is calculated using the formula,

Sum of the interior angles = (n-2) × 180°

For the given polygon, the number of sides is equal to 6. Therefore, the sum of the interior angles of the polygon is,

Sum of the interior angles = (6-2) × 180°

                                            = 4 × 180°

                                            = 720°

Further, the sum of the interior angles for the given polygon can be written as,

Sum of the interior angles = 102° + 146° + 120° + 124° + 158° + x°

720° = 102° + 146° + 120° + 124° + 158° + x°

x = 720° -  (102° + 146° + 120° + 124° + 158°)

x = 720° - 650°

x = 70°

Hence, the value of the x is 70°.

4. The cube of 4 in expanded form is: 4 × 4 × 4 = 64.

5. Four times three is not the same thing as cube of a number, but rather 4 × 3 = 12.

The cube of a number means the number multiplied by itself three times. With the knowledge of this, we can write the cube of any number in expanded form.

For example, given a number y, the cube of y is = y³

This means that y multiplied by itself three times, which can be written in expanded form as: y × y × y = y³

If y is 2, the cube of 2 would mean: 2³ = 2 × 2 × 2 = 8.

Therefore:

4. Four cubed is 4³

In expanded form, it is: 4 × 4 × 4, which is evaluated as = 64.

5. Four times 3 in numbers is: 4 × 3, which is evaluated as = 12.

Answer:

1.096

Step-by-step explanation:

the answer is 1.096

The residual value for the coordinate (4, 6) is 1.096.

The estimated value of a fixed asset at the conclusion of its useful life or lease term is known as the residual value.

Given,

y = 1.416x − 0.76

For (4.6)

As, residual value = Measured value - Predicted value

or, residual value = (actual y-coordinate of the point) - (value of y from the equation)

When x = 4:

So, the value of y from the equation,

y' = 1.416*4-0.76 = 4.904

and, actual y-coordinate of the point, y = 6

Residual value = 6 - 4.904 = 1.096

Hence, The residual value for the coordinate (4, 6) is 1.096.

the acosta family went out to dinner. the price of the meal was $79.85. if the tip was 15%.The Acosta family paid $91.83 for the meal, including the 15% tip.

To calculate the total amount paid, we need to add the original price of the meal to the tip amount. The price of the meal was $79.85, and the tip was 15% of that amount. To find the tip, we multiply $79.85 by 0.15 (or 15% expressed as a decimal), which equals $11.98. Adding the tip of $11.98 to the original price, the total amount paid is $91.83.

In more detail, a 15% tip means that 15% of the meal price is added as an extra amount to the bill. To calculate the tip, we multiply the meal price ($79.85) by 0.15 (or 15% as a decimal), resulting in $11.98. This represents the additional amount the Acosta family paid for the tip. To find the total amount paid, we add the tip amount to the original meal price: $79.85 + $11.98 = $91.83. Therefore, the Acosta family paid $91.83 for the meal, including the tip.

c. No, w is not in the subspace spanned by  {\({v_1, v_2, v_3}\)} since it is not a linear combination of these three vectors.

a. To find if w is in {v₁, v₂, v₃}, we need to check if w is equal to a linear combination of v₁, v₂, and v₃. That is, we have to check if there exist constants c1, c₂, and c₃ such that:

c₁v₁ + c₂v₂ + c₃v₃ = w

Substituting the given values,

Solving this system of equations, we can that there are no values of c₁, c₂, and c₃ that satisfy the equation.

Therefore, w is not in {v₁, v₂, v₃}.

b. The set {v₁, v₂, v₃} has three vectors, and any linear combination of these vectors will be in the span of {v₁, v₂, v₃}. Therefore, to calculate the number of vectors in Span {v₁, v₂, v₃}, we need to find linear combinations of these vectors are possible.

Since Each vector in the span is a linear combination of v₁, v₂, and v₃, so there are infinitely many vectors in Span {v₁, v₂, v₃}.

Step-by-step explanation:

The equation representing the amount earned by the plumber, given the number of hours worked, can be expressed as: y = 30x + 25

To find the total amount earned by the plumber, we multiply the number of hours worked, x, by the hourly rate of $30 and then add the fixed service charge of $25. This equation allows us to calculate the earnings, y, based on the hours worked, x.

The equation representing the amount earned by the plumber, given the number of hours worked, can be expressed as:

y = 30x + 25

In this equation, "y" represents the amount earned by the plumber, "x" represents the number of hours worked, $30 represents the hourly rate, and $25 represents the service charge. The term "30x" calculates the earnings based on the hourly rate, and the constant term of $25 accounts for the service charge added to the total earnings.

The simple interest rate that will ensure that Bob's investment of R6,500 equals Alice's 3% compound interest per year investment is 3.2%.

The difference between simple interest and compound interest is that simple interest computes interest on the principal only for each period.

Compound interest computes interest on both the principal and accumulated interest for each period.

Alice:

Principal investment = R6,500

Compound interest rate per year = 3%

Investment period = 5years

Future value = R7,535.28 (R6,500 x 1.03⁵)

Total Interest R1,035.28 (R7,535.28 - R6,500)

Bob:

Principal invested = R6,500

The simple interest rate = r

Investment period = 5years

The future value of the simple interest investment, A = P(1+rt)

7,535.28 = 6,500(1 + 5r)

Answer:

third number = 4,

equation of y, y = 5x - 11

equation of n, n = 4x

equation of x, n + x + y =19

Step-by-step explanation:

so lets write evertything as a n equation. n + x + y =19. N is the first number, x is the second number, and y is the third number. We will write the equation for y as follows 5x - 11. N will be four times the second number, so 4x. If substitute the values for out equation for x we will find what x equals to. So (4x) + x + (5x - 11) = 19

10x = 30

x = 3.

Then you substiute the answer for x in the equation for y. This will get you 5(3) - 11

It will take them 3 days to paint the building if they work together on it except for 1 day when the painter is ill and the apprentice works alone is the answer.

Given that a painter can paint a building in 4 days and his apprentice can do it in 6 days, the following steps can be taken to find out the time taken to paint the building when they work together on it except for 1 day when the painter is ill and the apprentice works alone.

Step 1: Let's find the painter's work efficiency.

The painter can paint a building in 4 days. It means, in 1 day, the painter can complete 1/4 of the work.(1/4) × (4 days) = 1 work done

Therefore, the painter can complete 1 work in 1 day.

Step 2: Let's find the apprentice's work efficiency.

The apprentice can paint a building in 6 days. It means, in 1 day, the apprentice can complete 1/6 of the work. (1/6) × (6 days) = 1 work done

Therefore, the apprentice can complete 1 work in 1 day.

Step 3: Let's find out their combined work efficiency.

In 1 day, the painter can complete 1 work and the apprentice can complete 1 work.

So, in 1 day, their combined work efficiency = 1 + 1 = 2 works done.

Step 4: Let's find out the time taken to complete the work if they work together on it except for 1 day when the painter is ill and the apprentice works alone. If they work together for x days (except for 1 day when the painter is ill and the apprentice works alone), then, the following equation can be formed: Painter's work done in x days + Apprentice's work done in x days = Total work to be done.

Painter's work done in x days = (1/4) × (x - 1) = (x - 1)/4.

Apprentice's work done in x days = (1/6) × x = x/6.

Total work to be done = 1.

So, the equation becomes:(x - 1)/4 + x/6 = 1.

⇒ 3(x - 1)/12 + 2x/12 = 1.

⇒ (3x - 3 + 2x)/12 = 1.

⇒ 5x - 3 = 12.

⇒ 5x = 15.

⇒ x = 3.

Therefore, it will take them 3 days to paint the building if they work together on it except for 1 day when the painter is ill and the apprentice works alone.

Answer:

⅓ ×½ which will give you ⅙

Step-by-step explanation:

because

The probability that Manu will win the coin flip amongst others is 4/7

To determine the probability that Manu will win, we need to consider the possible outcomes of the coin flips.

Let's break down the scenarios:

Scenario 1: Manu wins on the first flip

- The probability of Manu winning on the first flip is 1/2, as he needs to flip heads right away.

Scenario 2: Manu wins on the second flip

- Juan flips tails (1/2 probability)

- Carlos flips tails (1/2 probability)

- Manu flips heads (1/2 probability)

- The probability of Manu winning on the second flip is (1/2) * (1/2) * (1/2) = 1/8.

Scenario 3: Manu wins on the third flip

- Juan flips tails (1/2 probability)

- Carlos flips tails (1/2 probability)

- Manu flips tails (1/2 probability)

- Juan flips heads (1/2 probability)

- Carlos flips heads (1/2 probability)

- Manu flips heads (1/2 probability)

- The probability of Manu winning on the third flip is (1/2) * (1/2) * (1/2) * (1/2) * (1/2) * (1/2) = 1/64.

The pattern continues, and we can see that Manu's probability of winning decreases exponentially with each subsequent flip.

Therefore, the total probability of Manu winning is the sum of the probabilities from each scenario:

1/2 + 1/8 + 1/64 + ...

This is an infinite geometric series with a first term (a) of 1/2 and a common ratio (r) of 1/8.

Using the formula for the sum of an infinite geometric series:

Sum = a / (1 - r)

Sum = (1/2) / (1 - 1/8)

Sum = (1/2) / (7/8)

Sum = (1/2) * (8/7)

Sum = 4/7

Therefore, the probability that Manu will win is 4/7.

Answer:

The shortest path to take is \(20\sqrt{3}\ cm\) or \(34.64\ cm\)

Step-by-step explanation:

This question requires an attachment (See attachment 1 for question)

Given

Cube Dimension: 20cm * 20cm

Required

Shortest path from A to B

For proper explanation, I'll support my answer with an additional attachment (See attachment 2)

The shortest path from A to B is Line labeled 2

But first, the length of line labeled 1 has to be calculated;

This is done as follows;

Since, the cube is 20 cm by 20 cm

\(Line1^2 = 20^2 + 20^2\) (Pythagoras Theorem)

\(Line1^2 = 2(20^2)\)

Take square root of both sides

\(Line1 = \sqrt{2(20)^2}\)

Split square root

\(Line1 = \sqrt{2} * \sqrt{20^2}\)

\(Line1 = \sqrt{2} * 20\)

\(Line1 = 20\sqrt{20}\)

Next is to calculate the length of Line labeled 2

\(Line2^2 = Line1^2 + 20^2\) (Pythagoras Theorem)

Substitute \(Line1 = 20\sqrt{20}\)

\(Line2^2 = (20\sqrt{2})^2 + 20^2\)

Expand the expression

\(Line2^2 = (20\sqrt{2})*(20\sqrt{2}) + 20 * 20\)

\(Line2^2 = 400*2 + 400\)

Factorize

\(Line2^2 = 400(2+1)\)

\(Line2^2 = 400(3)\)

Take square root of both sides

\(Line2 = \sqrt{400(3)}\)

Split square root

\(Line2 = \sqrt{400} * \sqrt{3}\)

\(Line2 = 20 * \sqrt{3}\)

\(Line2 = 20 \sqrt{3}\)

The answer can be left in this form of solve further as follows;

\(Line2 = 20 * 1.73205080757\)

\(Line2 = 34.6410161514\)

\(Line2 = 34.64 cm\) (Approximated)

Hence, the shortest path to take is \(20\sqrt{3}\ cm\) or \(34.64\ cm\)

Answer:

44.72 cm

Step-by-step explanation:

1. This was marked correct by RSM

2. Unfold the cube, so that points A and B and on points diagonal from each other on a 40 cm x 20 cm rectangle. Now draw a line connecting points A to B. That is the hypotenuse of both triangles. Now according to the pythagorean theorem, the hypotenuse is √2000, which is equal to 5√20.

3. The answer is 44.72 cm

The transformations of the triangle ABC to A'B'C' are (a) and (e)
