A Circular pool has diameter of 24 feet what's the area of the cover - 452.16 square feet - 75.36 square feet - 150.72 square feet - 1,808.64 square feet

Answers

Answer: 452.16 square feet

Step-by-step explanation:

The formula that is used to calculate the area of a circle is given as:

= πr²

where π = 3.14

r = Diameter/2 = 24/2 = 12

Area = πr²

= 3.14 × 12²

= 3.14 × 144

= 452.16 feet²

Therefore, the answer is 452.16 square feet.

Executives from Six Flags, a well-known amusement park chain, had interest in constructing a Six Flags theme park in a location near Ames city limits. Experts believed that approximately 15% of the surrounding population would be interested in becoming season ticket holders.

What is the distance between two points?

It is the measure of distance between the two points and is known as length. The length is measured in meters generally.

Let one point be (x, y) and another point be (h, k). Then the distance between the points will be given as,

D² = (x - h)² + (y - k)²

From the diagram, the points are M(2, 5) and P(7, 17). Then the distance between the mall and the post office is calculated as,

MP² = (7 - 2)² + (17 - 5)²

MP² = 5² + 12²

MP² = 25 + 144

MP² = 169

MP = 13

A class has $90 to spend on a field trip. The field trip costs $2.50 per person and there will be 5 chaperones on the trip. One student used the inequality 90 greater-than 2.50 (x + 5) to find x, the number of students that the field trip budget could accommodate. Which best describes the error in the student’s inequality?
The expression representing the cost should be 2.50 (5 x).
The expression representing the cost should be 2.50 (x + 5 x).
The inequality symbol should be Greater-than-or-equal-to instead of > since up to and including $90 may be spent.
The inequality symbol should be Less-than-or-equal-to instead of > since less than or equal to $90 may be spent.

Answers

Answer:

The inequality sign is not correct because the > symbol means greater than. However, up to and including $90 can be spent so the inequality sign should be ≥ (greater than or equal to).

The best description of the error in the student's inequality is; The inequality symbol should be Greater-than-or-equal-to instead of > since up to and including $90 may be spent.

What is the representation of the inequality?

We are told that;

Amount for the class to spend = $90

Cost of field trip = $2.5 per person

Number of persons on the trip = 5 persons

Inequality used by a student is;

90 > 2.5(x + 5)

The inequality sign used above is not correct because the they have $90 to spend and so the inequality sign should be ≥ (greater than or equal to).

B. 140 degrees
C. 250 degrees
D. 110 degrees​

Answers

The answer is 70 degrees

The measure of the angle with variable x is 70 degrees.

TangentsTangent which meet at the same point are equal in lengthThe two tangent sides are equal

The two tangents forms an angle x. The angle x is opposite the arc angle 250 degrees.

∠x =  250 - (360 - 250)/ 2

∠x = 250 - 110 / 2

∠x = 140 / 2

∠x = 70°

Therefore, ∠x = 70 degrees.

There is a line that includes the point (3, 3) and has a slope of 4. What is its equation in
slope-intercept form?

Answers

Answer:

         y = 4x - 9  

Step-by-step explanation:

The equation in point-slope form with slpope of m and including point (x₁,y₁) is:

y - y₁ = m(x - x₁)

m = 4

(3, 3)  ⇒  x₁ = 3,  y₁ = 3

So:

y - 3 = 4(x - 3)     ←   the point-slope form

y - 3 = 4x - 12         {add 3 to both sides}

y = 4x - 9           ←  the slope-intercept form

Answer:

a) median=25 interquartile range=19

b) The Braineys as the median is 32 compared to 25.

Step-by-step explanation:

The median and interquartile range for the cleverites are : 25 and 20 respectively.

The slowest club on average is the Braineys

From https://brainly.com/question/14724605?referrer=searchResults :

The median value for the cleverites :

The Median is the time at the midpoint of the frequency curve :

Median frequency = Cummulative frequency / 2

Median frequency = 80 /2 = 40

Tracing to the intersection point on the curve and reading the x - value at the point of intersection ;

Median for the Cleverites is 25

The interquartile range = (upper quartile - lower quartile)

Upper quartile = 3/4(Cummulative frequency) = 3/4(80) = 60

Upper quartile = 35 minutes

Lower quartile = 1/4(80) = 20

Lower quartile = 15 minutes

Interquartile range = (35 - 15) = 20 minutes

To obtain the slowest club on average, we could use the median :

Median for Cleverites = 25

Median for Braineys :

1/2(80) = 40

Time on the x axis corresponding to y = 40 is 32

Comparing the median values :

32 > 25

Braineys > Cleverites ;

The slowest on average at competing is Braineys as they have a higher completion time.

A customer pay 72$ for 18 sandwiches. If each sandwich cost the same amount , what is the cost per sandwich, in dollars?

Answers

Answer:

Each sandwich costs 4$.

Step-by-step explanation:

To find the answer we will divide 72$ by 18 and we get 4$.

The number of sandwiches and the total price of sandwiches are directly proportional.

Cost of 18 sandwiches = $72

Cost of 1 sandwich = $72/18

= $4

Hence the cost of 1 sandwich is $4.
