Answer:

720°

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 6 ( number of sides of a hexagon ), thus

sum = 180° × 4 = 720°

The sum of the measures of the interior angles of a hexagon is [tex]720^{\circ}[/tex]

A polygon is a plane figure that is described by a finite number of straight line segments connected to form a closed polygonal chain. The bounded plane region, the bounding circuit, or the two together, may be called a polygon. A hexagon is a six-sided polygon or [tex]6-[/tex]gon. Interior angles are those that lie inside a polygon.

The total of the internal angles of any simple hexagon is [tex]\boldsymbol{720^{\circ}}[/tex]

Answer:

I believe that it would just be 20% of the $45 which would mean that you would have to pay $36 a month.

Hope this is helpful!

The cost to you per month, after the landlord's contribution, is $36.

If you buy both Liability and Contents insurance, and take advantage of the landlord's offer to pay 20% of the cost, the cost to you per month can be calculated as follows:

Let's assume the cost of Liability insurance is represented by 'L' and the cost of Contents insurance is represented by 'C'.

According to the information given, if you buy both insurances at the same time, the cost is $45 per month.

This means: L + C = $45

The landlord is willing to pay 20% of the cost, which is equal to 20% of ($45). To calculate this amount:

20% of $45 = (20/100) x $45 = $9

So, the landlord will pay $9 towards the cost of both insurances.

Now, if you subtract the landlord's contribution from the total cost, you'll get the amount you have to pay:

(L + C) - $9 = $45 - $9 = $36

Therefore, the cost to you per month, after the landlord's contribution, is $36.

Sally gave 30 shells to Jason

Solution:

Given that, Sally found 58 seashells on the beach, she gave Jason some of her seashells

She has 28 left

To find: Number of sea shells she gave to Jason

From given,

Total number of shells she found = 58

Remaining shells = 28

Answer:

The number of viruses was 2 times greater than bacteria.

Step-by-step explanation:

The number of viruses was [tex]2*10^9[/tex], and the number of bacteria was [tex]1*10^9[/tex].

To find how many times was the virus number greater than the bacteria number, we just divide the virus number by bacteria number:

[tex]\frac{ virus\:number }{bacteria\:number} =\frac{2*10^9 }{1*10^9} = 2*\frac{10^9}{10^9} =2[/tex]

Viruses are 2 times greater.

Answer:

Viruses are 2 times of the bacteria.

Step-by-step explanation:

Given:

Number of viruses = [tex]2\times 10^9[/tex]

Number of bacteria = [tex]1\times 10^9[/tex]

We have to found how many times viruses are greater than the bacteria.

To find how many times,we can divide both the numbers to compare its values.

Lets

Numerator = Number of viruses

Denominator = Number of bacteria

Dividing both we have,

⇒ [tex]\frac{2\times 10^9}{1\times 10^9}[/tex]

⇒ [tex]2\times 10^(^9^-^9)[/tex] ...[tex]\frac{ab^x}{cb^y}=\frac{ab^x^-^y}{c}[/tex]

⇒ [tex]2\times 10^0[/tex]       ...[tex]a^0=1[/tex]

Answer:

the answer is 4x-3

Step-by-step explanation:

To simplify the expression 3x + 4(x - 6) - 3(x - 7), distribute the multiplication across the parentheses, combine like terms, and simplify to get the final result: 4x - 3.

To simplify the expression 3x + 4(x - 6) - 3(x - 7), follow these steps:

Distribute the 4 into the second parenthesis: 4  imes x - 4  imes 6 which gives 4x - 24.

Distribute the -3 into the third parenthesis: -3  imes x + (-3)  imes (-7) which gives -3x + 21.

Combine like terms with the rest of the expression: 3x + (4x - 24) + (-3x + 21).

Add/subtract the x terms and constant terms: 3x + 4x - 3x (which simplifies to 4x) and -24 + 21 (which simplifies to -3).

The simplified form of the expression is 4x - 3.

Final answer:

Each carrot cost $2.10, found by dividing the total cost of $10.50 by the number of carrots, which is 5.

Explanation:

The student’s question relates to the basic concept of unit price in mathematics. Joe bought 5 carrots for a total of $10.50. To find out how much each carrot cost, we divide the total cost by the number of carrots.

Here’s the calculation step-by-step:

Determine the total cost of the carrots, which is $10.50.

Determine the number of carrots bought, which is 5 carrots.

Divide the total cost by the number of carrots: $10.50 / 5 = $2.10.

So, each carrot costs $2.10 when expressed as a decimal to the nearest hundredth.

1. Geometric Sequence

2. [tex]a_n = a_{n-1} * 3[/tex]

3. [tex]a_n = 6 * (3)^{n-1}[/tex]

Step-by-step explanation:

Given sequence is:

6, 18, 54, 162,....

Here

[tex]a_1 =6\\a_2 = 18\\a_3 = 54[/tex]

(a) Is this an arithmetic or geometric sequence?

We can see that the difference between the terms is not same so it cannot be an arithmetic sequence.

We have to check for common ratio (ratio between consecutive terms of a sequence) denoted by r

[tex]r = \frac{a_2}{a_1} = \frac{18}{6}= 3\\r = \frac{a_3}{a_2} = \frac{54}{18} = 3[/tex]

As the common ratio is same, the given sequence is a geometric sequence.

(b) How can you find the next number in the sequence?

Recursive formulas are used to find the next number in sequence using previous term

Recursive formula for a geometric sequence is given by:

[tex]a_n = a_{n-1} * r[/tex]

In case of given sequence,

[tex]a_n = a_{n-1} * 3[/tex]

So to find the 5th term

[tex]a_5 = a_4*3\\a_5 = 162*3\\a_5 = 486[/tex]

(c) Give the rule you would use to find the 20th week.

In order to find the pushups for 20th week, explicit formul for sequence will be used.

The general form of explicit formula is given by:

[tex]a_n = a_1 * r^{n-1}[/tex]

Putting the values of a_1 and r

[tex]a_n = 6 * (3)^{n-1}[/tex]

Hence,

Answer:

54.

Step-by-step explanation:

Start at 60 and subtract 6. That leaves you with 54.

The 60th term in the arithmetic sequence -6, -3, 0, 3, ... can be determined using the formula of an arithmetic sequence, which results in a value of 171.

An arithmetic sequence, also known as an , is a sequence of numbers in which each term is obtained by adding a fixed constant to the previous term. In simpler terms, it's a sequence where the difference between any two consecutive terms is always the same.

The given sequence is an arithmetic progression where each term differs from the previous term by a constant value. In this case, the common difference[tex](\(d\))[/tex]between consecutive terms is 3.

To find the 60th term of this sequence, we can use the formula for the nth term of an arithmetic sequence:

[tex]\[a_n = a_1 + (n - 1) \cdot d\][/tex]

Here,[tex]\(a_n\)[/tex]represents the nth term, \(a_1\) is the first term, \(n\) is the term number we want to find, and \(d\) is the common difference.

In this sequence:

- The first term [tex](\(a_1\)) is -6.[/tex]

- The common difference [tex](\(d\)) is 3.[/tex]

- We want to find the 60th term, so [tex]\(n = 60\).\\[/tex]

Now, we can substitute these values into the formula:

[tex]\[a_{60} = -6 + (60 - 1) \cdot 3\][/tex]

[tex]\[a_{60} = -6 + 59 \cdot 3\][/tex]

[tex]\[a_{60} = -6 + 177\][/tex]

[tex]\[a_{60} = 171\][/tex]

Therefore, the 60th term in this arithmetic sequence is 171. This means that if you continued the sequence, the 60th term would be 171 units greater than the first term (-6), following the pattern of adding 3 at each step.

To proof

Let us assume that the total diatance travelled into the country be x .

Formula

As given

A cyclist rides into the country at an average speed of 10 miles per hour. When his bicycle gets a flat tire,

he walks it back at an average speed of 3 miles per hour.

If he returns home 6 and a half hours after he starts i.e the total time including the bike time and walk time of the cyclist be 6.5 hours.

Than the equation becomes

L.C.M of (10,3) = 30

Than the equation becomes

3x +10x = 195

solving

13x = 195

x = 15 miles into the country

Hence proved
