A middle school took all of its 6th grade students on a field trip to see a ballet at a theatre that has 2000 seats. The students filled 90% of the seats in the theatre. How many 6th graders went on the trip?

Step 1) Use the area formula to find the length of the radius

A = (3.14 x r^2) / 4

3.14 = (3.14 x r^2) / 4

12.56 = 3.14r^2

r^2 = 4

r = 2 feet

Step 2) Use the perimeter formula to find the perimeter

C = ((pi x 2r) / 4) + 2r

C = ((3.14 x 4) / 4) + 4

C = (12.56 / 4) + 4

C = 3.14 + 4

C = 7.14 feet

Hope this helps! :)

Answer:

AE Measure: 23.36 units

Step-by-step explanation:

BA: 20cm

BC:20cm

BE:10cm  CE: 10cm

a^2 +b^2=c^2

BE^2 +BA^2 = AE^2

√100 + √400 = √500

AE^2 = √500 = 23.36

AE = 23.36 unit

Repeat effort :-)

Step-by-step explanation:

As ABCD is a square , BC = 20 cm

BE = 20/2 = 10 cm

Also , angle B = 90⁰

By pythagoras theorem :

AE² = 20² + 10²

AE² = 400 + 100

AE² = 500

AE = 10√5 cm

Answer:

1/6

Step-by-step explanation:

There are 4 cards, 2 of which are primes

P(prime) =number of primes/total

               = 2/4 = 1/2

Keep the card, now we have 3 cards, 1 of which is a prime

P(prime) =number of primes/total

               = 1/3

P(prime, keep , prime) = 1/2*1/3 = 1/6

A right triangular prism has 3 rectangular faces.

If each of the edges of the triangular base measures 4.5cm,

and the length (the height) of the prism is 22.5cm,

the 3 rectangular faces (sides of the box) are rectangles,

22.5cm long and 4.5cm wide.

Each face has a surface area of (22.5cm)(4.5cm)=101.25 square centimeters.

The total lateral surface area for the 3 rectangular sides of the box is

3(101.2 square centimeters)=303.75 square centimeters.

If the triangular faces of the box are triangles

with a base measuring 4.5cm and a height measuring 4.0cm,

the surface area of each triangular face is

(1/2)(4.5cm)(4.0cm)=9 square centimeters.

The surface area of the two triangular faces adds up to

2(9 square centimeters)=18 square centimeters.

The total surface area for the box is

303.75 square centimeters + 18 18 square centimeters= 321.75 18 square centimeters,

and that rounds up to highlight 322 square centimeters.

NOTE:

The answer above is the one your teacher wants,

but there is a problem with this problem.

An equilateral triangle with sides measuring 4.5cm

would have a height of approximately 3.9cm.

The Pythagorean theorem says so.

However, the 4.0cm value makes the calculations easier.

Answer:

A right triangular prism has 3 rectangular faces.

If each of the edges of the triangular base measures 4.5cm,

and the length (the height) of the prism is 22.5cm,

the 3 rectangular faces (sides of the box) are rectangles,

22.5cm long and 4.5cm wide.

Each face has a surface area of (22.5cm)(4.5cm)=101.25 square centimeters.

The total lateral surface area for the 3 rectangular sides of the box is

3(101.2 square centimeters)=303.75 square centimeters.

If the triangular faces of the box are triangles

with a base measuring 4.5cm and a height measuring 4.0cm,

the surface area of each triangular face is

(1/2)(4.5cm)(4.0cm)=9 square centimeters.

The surface area of the two triangular faces adds up to

2(9 square centimeters)=18 square centimeters.

The total surface area for the box is

303.75 square centimeters + 18 18 square centimeters= 321.75 18 square centimeters,

and that rounds up to highlight 322 square centimeters.

Answer:

The probability of a student to hit any small circle is 4.66 %.

Step-by-step explanation:

In order to determine the probability of the students to hit the small circles, we need to calculate the are of the rectangle and the area of each circle. These are shown below:

area circle = pi*r² = pi*(3)² = 28.26 in²

area rectangle = 35*52 = 1820 in²

Since there are three circles and the students can hit any of those the probablity of hitting them is given by the area of one circle multiplied by 3 and divided by the area of the rectangle.

p = [(3*area circle)/(area rectangle)]*100%

p = [(3*28.26)/1820]*100 = 4.66 %

Answer:

Part B

This statement means that we are 95% confident that our confidence interval and our point estimate of our results from this sample contains the true proportion of national adults who fulfill a certain condition. The margin of error is plus or minus 4 percentage points in our survey, so we are fairly accurate / close to our point estimate.

Part C

Personally, I think that the minimum quota should be different, because nowadays very few people have landlines, and most people have cell phones. I would put it at 80% cell phones, 20% landlines, for the most representative survey possible.

Part D

Unfortunately, there isn't enough information to explain this one, because I can't see the link or view the responses and trends. I would give you the advice that you might want to include all variables and survey conditions: what type of survey was it? how many adults were sampled? what are your hypotheses or preconceived notions? what is the standard error? This should help; if not, please clarify.

Answer: Reasonable

Step by Step:

You add week 1 and week 2

so, 11.9 + 15.05 = 26.95

That's basically it

The total distance travelled is 26.95, and the steps followed are given.

Sum is the output of the mathematical operation, Addition.

Jessica added the two distances in the table to get a sum of 26.95 miles.

The step followed to determine the sum of the distances is

Step 1:

Total distance travelled =  Distance travelled in Week 1 +  Distance travelled in Week 2

Step 2:

Total distance = 11.9 + 15.05

Total distance = 26.95 miles

Step-by-step explanation:

Answer:

I think its 66

Step-by-step explanation:

Since if you draw it out properly F would be opposite of H.

Oppsite angles in a quadrilateral are supplementary(in a circle at least) meaning they add up to 180.

So 180-114= 66

So H=66

As per the question of the triangle, ABC is a rotation triangle and has an origin of the center as the location of rotation. The tringle is on a coordinated plane and the triangle ABC has points as 4, 3, 5, negative.

The A, B, C as a prime number of points (4, 3), (5, 2), (3, 2).  The triangle is formed by the sequences of formations and transformations that will give out.

As the triangle is a right-angled triangle the ABC will be arranged in a series of sequences that shows the reflections from all the sides and hence the reflection is over the y axis and these are all related to the formation of the ABC.
