Answer:

No diagram and no explanation what 9 is.

However, if it is an octagon with each side equal to 9 then

area = (# of sides * side^2) / (4 * tan (180 # of sides))

area = 8 * 9 * 9 / (4* tan (180 / 8)

area = 648 / 4 * 0.41421

area = 391.1059607446

answer is C

Step-by-step explanation:

The area of the considered octagon which has distance from its center to the vertex of 9 m is given by: Option b). 229.1 m²

If the regular octagon has sides of 'a' units, then its area is:

[tex]A = 2(1+\sqrt{2})a^2 \: \rm unit^2[/tex]

Consider the attached figure below (second figure too).

If we find the value of 'a', then we can use the above formula.

Since there are 8 equal sides in a regular octagon, the angle from center to each of the side is full angle / 8 = 360/8 = 45 degrees.

Since the angle OA is perpendicular on BC, due to symmetry, we have the angle BOC divided into 2 parts.

Thus, we get:

m∠AOB = 45/2 degrees = 22.5°

Using the sine ratio from the perspective of angle AOB, we get:

[tex]\sin(m\angle AOB) = \dfrac{|AB|}{|OB|}\\\\\sin(22.5^\circ) = \dfrac{a/2}{9}\\\\a \approx 2 \times 9 \times 0.38268 \approx 6.888[/tex] meters

(since length of AB is half of length of BC, which is 'a' units).

Thus, we get:

[tex]A = 2(1+\sqrt{2})a^2 \approx 2(1+\sqrt{2})(6.888)^2 \approx 229.1\: \rm m^2[/tex]

Thus, the area of the considered octagon which has distance from its center to the vertex of 9 m is given by: Option b). 229.1 m²

Answer:

y=4x+13  or y-5=4(x+2)

Step-by-step explanation:

we know that

The equation of the line into point slope form is equal to

y-y1=m(x-x1)

In this problem we have

m=4

(x1,y1)=(-2,5)

substitute

y-5=4(x+2) ----> equation of the line into point slope form

Convert to slope intercept form

y-5=4x+8

y=4x+8+5

y=4x+13 ----> equation of the line into slope intercept form

Answer:

(A) 180

Step-by-step explanation:

We have to treat those player selections as independent events, since one doesn't influence the other (the fact you chose Joe as a guard, shouldn't have an influence on who'll pick as center, unless there's bad blood between some players... but that's a whole other story).

So, how many ways to pick 2 guards from a selection of 4?  The order doesn't seem to matter here, since they don't specify for example that Joe can only play on the left side).  So, it's a pure combination calculation:

[tex]C(4,2) = \frac{4!}{2! * (4 - 2)!} = \frac{24}{2 * 2} = 6[/tex]

C(4,2) = 6.

How many ways to pick the 2 forwards from a group of 5?  Using the same calculation, we get:

C(5,2) = 10.

And of course, the coach has 3 ways to pick a center player from 3.

Then we multiply the possible ways to pick guards, forwards and center...

6 * 10 * 3 = 180 ways.

190.18 is the average balance

Answer:

The answer is $190.18

Step-by-step explanation:

When we calculate the average daily balance, we total the balance from each day in the billing cycle and divide the total by the number of days in the cycle. Here the billing cycle is given for July that has 31 days.

Lets calculate each days amount.

Opening balance from 1st July to 7th July = $209.53

So, it is a total of 7 days; amount is [tex]209.53\times7=1466.71[/tex]

On 8th July a payment of $50 is made making the amount

[tex]209.53-50=159.53[/tex]

So, from 8th July to 15th July (8 days), the balance was $159.53 making a total of [tex]159.53\times8=1276.24[/tex] dollars

On 16th July a charge of $20 was added, so from 16th July to 23 July (8 days), the amount became = [tex](159.53+20)\times8=1436.24[/tex] dollars

On 24th July additional charge of $35 was added and the period it remained same was till 31st July, making it 8 days.

So, amount is = [tex]214.53\times8=1716.24[/tex] dollars

Now adding all the charges we get;

[tex]1466.71+1276.24+1436.24+1716.24= 5895.43[/tex] dollars

Now we will divide this by 31 days to get the average daily balance.

[tex]\frac{5895.43}{31}=190.175[/tex]  ≈ $190.18

Answer:

The population of 75 hours from now would be 40,000.

Step-by-step explanation:

The reason for this is because your initial number is 10,000 and when 25 hours pass by, your population would be 20,000. Another 25 hours pass by, and then your population would be 40,000. If you multiply 25 by 3, you will notice 75 hours have just passed, so your answer would be 40,000.

The population of a bacterial colony that doubles every 25 hours will increase exponentially. In this case, starting from a population of 10,000 bacteria, after 75 hours, we will have 80,000 bacteria. This demonstrates the concept of exponential growth commonly seen in bacteria.

The population of a bacterial colony that doubles every 25 hours follows an exponential growth model. This process is where the increasing rate is proportional to the current scope, leading to continued growth. If we start with a colony of 10,000, after 25 hours, we will have 20,000 bacteria. After another 25 hours, this will double again to 40,000. And after a final 25 hours, we double the number again to 80,000.

Here are the calculations:

This demonstrates the concept of exponential growth commonly seen in the bacteria populations. The growth rate increases over time due to the characteristic of bacteria to divide and reproduce, leading to a rapid increase in their numbers.

The linear equation -3y=x-6 can be graphed using the slope-intercept form y = -1/3x + 2. By choosing different values for x and solving for y, we can find three points that solve the equation. Plotting these points on a graph and connecting them with a line represents the linear equation.

The linear equation -3y=x-6 can be rewritten in slope-intercept form as y = -1/3x + 2. This form allows us to easily determine the slope and y-intercept of the equation. The slope is -1/3, which means for every increase of 1 in x, y decreases by 1/3. The y-intercept is 2, which indicates that the line crosses the y-axis at the point (0, 2).

To find three points that solve the equation, we can choose different values for x and substitute them into the equation to solve for y. Let's choose x = 0, x = 3, and x = -3. Plugging these values into the equation, we get y = 2, y = 1, and y = 3, respectively.

Therefore, the three points that solve the equation are (0, 2), (3, 1), and (-3, 3). When we plot these points on a graph, we can then connect them with a straight line to represent the linear equation.

Answer:

Can't really show a graph but I'll explain how to:

Answer:

The statement which not true is (A)

Step-by-step explanation:

* At first lets revise the volume of the cone and the cylinder

- The cone has circular base and one vertex

- Its height is the line joining the vertex and the center of the base

- Its volume is 1/3(BH), where B is the area of its base and H is its height

- The cylinder has two circular bases

- Its height the line joining between the centers of the two bases

- Its volume = BH, where B is the area of its base and H is its height

* Now lets solve the problem

- The ice cream cup is shaped cylinder with diameter 3 inches

  and height 3 inches

- The ice ream cone is shaped a cone with diameter 4 inches

  and height 6 inches

* Lets find the volume of the ice cream cup

- The volume of the ice cream cup = BH

∵ B = πr² ⇒ area the circle

∵ Its diameter is 3 inches

∵ The radius = 1/2 the diameter

∴ r = 3 × 1/2 = 1.5 inches

∴ B = π(1.5)² = 2.25π inches²

∵ H = 3 inches

∴ V = 2.25 × 3 = 6.75π inches³

* Lets find the volume of the ice cream cone

- The volume of the ice cream cone =1/3 BH

∵ B = πr² ⇒ area the circle

∵ Its diameter is 4 inches

∵ The radius = 1/2 the diameter

∴ r = 4 × 1/2 = 2 inches

∴ B = π(2)² = 4π inches²

∵ H = 6 inches

∴ V = 1/3 × 4π × 6 = 8π inches³

* Lets find the right answer

# (A)

∵ The volume of 24-pack of ice ream cups = 24 × 6.75π = 162π inches³

∵ The volume of 21-pack of ice ream cones = 21 × 8π = 168π inches³

∵ 162π < 168π

∴ (A) Not true

# (B)

∵ The volume of 12-pack of ice ream cups = 12 × 6.75π = 254.5 inches³

∵ 254.5 inches³ > 250 inches³

∴ (B) is true

# (C)

∵ The volume of 14-pack of ice ream cons = 14 × 8π = 351.9 inches³

∵ 351.9 inches³ > 350 inches³

∴ (C) is true

# (D)

∵ The volume of 12-pack of ice ream cups = 12 × 6.75π = 81π inches³

∵ The cylinder container has height = 8 inches

∵ The cylinder container had diameter = 6 inches

∴ its raduis = 1/2 × 6 = 3

∵ The volume of the cylinder container = BH

∵ B = πr² = π(3)² = 9π

∴ Its volume = 9π × 8 = 72π

∵ 81π > 72π

∴ (D) is true

* The statement which not true is (A)

Answer:

3.71 miles farther.

Step-by-step explanation:

To answer this, subtract 3  5/8 miles from 7  1/3 miles:

22/3 - 29/8 (miles)

Here the LCD is 24.  Thus, we have:

176      87                       89

------ - ------  (miles), or -------  (miles)

24       24                       24

Arun has to walk another 89/24 miles, or 3.71 miles.

Check:  do 3  5/8 miles and 3.71 miles add up to 7  1/3 miles?  Yes, approximately.

Arun has 89/24 miles left to walk to reach his friend's house.

Arun decided to walk 7 1/3 miles to his friend's house. After walking 3 5/8 miles, he stopped to rest. To calculate how much farther Arun has to walk to reach his friend's house, we subtract the distance he has already walked from the total distance he needs to walk.

The total distance to his friend's house: 7 1/3 miles = 7 + 1/3 = (7 × 3 + 1)/3 = 22/3 miles.

Distance already walked: 3 5/8 miles = 3 + 5/8 = (3 × 8 + 5)/8 = 29/8 miles.

To find the remaining distance, we subtract 29/8 miles from 22/3 miles:

First, find a common denominator for the fractions, which is 24. Convert both fractions: 22/3 × 8/8 = 176/24 and 29/8 × 3/3 = 87/24.

Now subtract the distances: 176/24 - 87/24 = 89/24 miles.

Therefore, Arun has 89/24 miles left to walk to reach his friend's house.

Answer:

A

Step-by-step explanation:

1. Line l is cut by line a (let it be named a, because the figure doesn't show its name). Angles 1 and 6 are vertical, so they are congruent.

2.  Line m is cut by line a. Angles 3 and 8 are vertical, so they are congruent.

3. Parallel lines l and m are cut by transversal a. Angles 6 and 3 are congruent as alternate interior angles.

Hence,

[tex]3x+25=4x-17,\\ \\3x-4x=-17-25,\\ \\-x=-42,\\ \\x=42^{\circ}.[/tex]

4. The measure of angle 6 is

[tex]3x+25=3\cdot 42+25=126+25=151^{\circ}.[/tex]

5. Angles 6 and 2 are supplementary angles, so they add up to 180°:

∠2=180°-∠6=180°-151°=29°

Answer:

It should be  B I me

Step-by-step explanation:

To determine which percentage is higher, we need to calculate the percentage of boys who prefer green and the percentage of girls who prefer red.

Percentage of boys who prefer green:

Total number of boys = 2 + 4 + 4 + 5 = 15

Number of boys who prefer green = 5

Percentage of boys who prefer green = (5/15) x 100% = 33.33% (rounded to the nearest whole number, this is 33%)

Percentage of girls who prefer red:

Total number of girls = 4 + 3 + 1 + 3 = 11

Number of girls who prefer red = 4

Percentage of girls who prefer red = (4/11) x 100% = 36.36% (rounded to the nearest whole number, this is 36%)

Therefore, the percentage of girls who prefer red (36%) is higher than the percentage of boys who prefer green (33%).

The answer is B. At 36%, the percentage of girls who prefer red is higher.

Answer:

Snowboard can be purchased for the lowest price from Store C offering 40% discount.

Step-by-step explanation:

We need to compare discounts of 3 stores and find the store selling snowboard lowest of them.

Store A: Sale of 30% off and a successive discount of 10% off.

The formula used for successive discount is = (x+y - xy /100)%

here x= 30 and y =10 so total discount is:

Total discount = ( 30 +10 - (30*10)/100)%

                       = (40 - 300/100) %

                       = (40 -3) % = 37%

Original price = $189.59

Discount offered = 37% of $189.59

                            = 37/100 * 189.59 = $70.15

Selling Price = Original price - Discount offered

                     = $189.59 - $70.15

                     = $ 119.44

Store B: Sale of 20% off and a successive discount of 20% off.

The formula used for successive discount is = (x+y - xy /100)%

here x= 20 and y =20 so total discount is:

Total discount = ( 20 +20 - (20*20)/100)%

                       = (40 - 400/100) %

                       = (40 -4) % = 36%

Original price = $189.59

Discount offered = 36% of $189.59

                            = 36/100 * 189.59 = $68.25

Selling Price = Original price - Discount offered

                     = $189.59 - $68.25

                    = $ 121.34

Store C: Sale of 40% off.

Original price = $189.59

Discount offered = 40% of $189.59

                            = 40/100 * 189.59 = $75.84

Selling Price = Original price - Discount offered

                     = $189.59 - $75.84

                    = $ 113.75

So, Store A Sale price is: $ 119.44

Store B Sale price is: $ 121.34

and Store C Sale price is: $ 113.75

So, Comparing them we found that snowboard can be purchased for the lowest price from Store C offering 40% discount.
