Answer:

see below

Step-by-step explanation:

The circumference of a circle is given by

C = 2 * pi * r

176 = 2 * pi * r

Divide each side by 2 pi

176 / 2 pi = r

88/ pi = r

We can find the area by

A = pi r^2

A = pi ( 88/ pi) ^2

A =7744/pi

Letting pi = pi button

A =2464.991759 cm^2

A = 2465 cm^2

Letting pi = 3.14

A =2466.242038 cm^2

A = 2466.2 cm^2

Answer:

2463.01 cm²

Step-by-step explanation:

First, find the radius using the circumference formula:

C = 2[tex]\pi[/tex]r

176 = 2[tex]\pi[/tex]r

Divide each side by 2 pi

28 = r

Then, use the circle area formula:

A = [tex]\pi[/tex]r²

A = [tex]\pi[/tex](28²)

A = 2463.01

So, the area of the circle is 2463.01 cm²

Answer:

4

Step-by-step explanation:

Given that:

Let the two numbers = a and b

H. C. F of the two numbers = 2

L.C.M of the two numbers = 54

If a = 27 ; b =?

The product of a and b = product of their L. C. M and H. C. F ;

HENCE ;

27 * b = 2 * 54

27b = 108

b = 108/27

b = 4

Hence, second number is 4

Answer:

The best time is 56.81 seconds

Average leg time is 58.3825 seconds

Step-by-step explanation:

Here, we want to start by stating the team’s best time for the race

The team’s best time for the race is the smallest time spent on a lap

From the times given, the best time is 56.81 seconds

Now, we want to calculate the average time

We simply add up all these and divide by count

Mathematically, that will be;

(56.81 + 59.22 + 57.39 + 60.11)/4 = 58.3825 seconds

Answer:

65MPH (or 65 miles)

Step-by-step explanation:

I used a proportion:

487.5MI/7.5HR = ?MI/1HR

(mi/hr = mi/hr)

cross multiply:

487.5 x 1 = 487.5

then divide:

487.5 divided by 7.5 =

[tex]-291[/tex]

Step-by-step explanation:

From the three terms, we can conclude that the arithmetic sequence for this sequence is [tex]a_{n}=4+(n-1)(-5)[/tex].

[tex]a_{60}=4+(60-1)(-5)[/tex]

[tex]=-291[/tex]

∴ The 60th term of the arithmetic sequence is [tex]-291[/tex].

Answer:

Maximum daily revenue = $2,249,600

Step-by-step explanation:

If you approach this problem with a trail and error mindset you can quickly calculate that if you take an increase of $6  per ticket or $76 per ticket, then subtract the equivalent loss of visitors which would be 800 * 3 or 2,400 then you get 29,600 visitors. By simply multiplying this number by the cost of the tickets you achive  2,249,600 daily. This could be wrong as I did not use a formula.

Answer:

  see below

Step-by-step explanation:

The given equation is in "slope-intercept" form:

  y = mx + b

where m represents the slope, and b represents the y-intercept.

Your equation has b=2, so one of the points will be on the y-axis at y=2.

__

The slope is m = 3/4. The slope is "rise"/"run" which is the ratio of vertical travel to horizontal travel. The 3/4 means the line will rise 3 units for each 4 units to the right. You can count off the grid squares from (0, 2), the y-intercept, to find another point 4 units right and 3 units up, at (4, 5).

Your line will go through these points.

Answer:

15

Step-by-step explanation:

that is the answer

The next three terms are 15, 26 and 41.

The distance between succeeding terms in an arithmetic series is always the same.

An ordered group of numbers with a shared difference between each succeeding word is known as an arithmetic sequence.

For instance, the common difference in the arithmetic series 3, 9, 15, 21, and 27 is 6. An arithmetic progression is another name for an arithmetic sequence.

Given:

First term, a: 2

Common difference, d: 13

So, second term = a+ d

                            = 2 + 13 = 15

and, third term = a+ 2d

                            = 2 + 2(13) = 28

and, fourth term = a+ 3d

                            = 2 + 3(13) = 41

Hence, the next three terms are 15, 26 and 41.

Answer:

It will take 18 weeks

Step-by-step explanation:

Here, we are told that she owes a total of $81 which decreases at a rate of $4.50 per week

The number of weeks it will take to finish paying the debt will be the amount owed divided by the payment per week

Mathematically that is 81/4.5 = 18

Answer:

$13.50

Step-by-step explanation:

Multiply the price by the discount, then subtract that number from the original price.

15.00 x 10% = $1.50

$15.00-$1.50 = $13.50

Answer:

$13.5

Step-by-step explanation:

Discount is 10%

So 15*10/100=$1.5

$15-$1.5=$13.5

Answer:

3x + 4y = 16  The rule is you can do any valid operation on both sides of an equation and it will still be equal. Subtract 4y.

3x = -4y + 16  Divide by 3.

x = -4y/3 + 16/3  Answer B.

The solution for the equation 3x + 4y = 16 for x is (16 - 4y)/3 or 16/3 - 4y/3. The correct option is D.

The slope-intercept form of the equation of a line is y = mx + b.

To solve for x, we need to isolate x on one side of the equation. To do this, we can follow these steps:

Move the term containing y to the other side of the equation by subtracting 4y from both sides:

3x + 4y - 4y = 16 - 4y

Simplifying the left-hand side gives:

3x = 16 - 4y

Divide both sides by 3 to isolate x:

3x/3 = (16 - 4y)/3

Simplifying the left-hand side gives:

x = (16 - 4y)/3

So the solution for x is:

x = (16 - 4y)/3

Thus, the correct option is D.

The rates for both person are equal.

In general, the term "proportion" refers to a part, share, or amount that is compared to a total.

According to the concept of proportion, two ratios are in proportion when they are equal.

Two ratios or fractions are equal when an equation or a declaration to that effect is utilised.

A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio. "::" or "=" are symbols used to indicate proportions.

Given:

Person 1 run 20 laps in 6 minutes.

Then the ratio = 20/6

                        = 10/ 3

Person 2 run 30 laps in 9 minutes.

Then the ratio = 30/9

                        = 10/ 3

So, the rates are equivalent.
