A middle school took all of its 6th grade students on a field trip to see a play at a theatre that has 5000 seats. The students filled 4500 of the seats in the theatre. What percentage of the seats in the theatre were filled by the 6th graders on the trip?

Answer:

-The volume of the cone is 100.5[tex]in^3[/tex] .

Step-by-step explanation:

To find the volume of cone, you need the formula:

[tex]V =\frac{1}{3} \pi r^2 h[/tex]

-Use the radius and the height for the formula:

[tex]V =\frac{1}{3} \pi 4^2 6[/tex]

-Then, you solve:

[tex]V =\frac{1}{3} \pi 4^2 6[/tex]

[tex]V = \frac{1}{3}\pi[/tex] × [tex]4^2[/tex] × [tex]6[/tex]

[tex]V = \frac{1}{3}\pi[/tex] × [tex]16[/tex] × [tex]6[/tex]

[tex]V = \frac{1}{3}\pi[/tex] × [tex]96[/tex]

[tex]V = \frac{96}{3} \pi[/tex]

[tex]V = 32\pi \approx 100.53[/tex]

-Round to the nearest tenth:

[tex]V \approx 100.5[/tex]

So, therefore, the volume of the cone is 100.5[tex]in^3[/tex] .

Answer:

No

Step-by-step explanation:

Not all parallelograms are rhombuses, some parallelograms include rectangles, squares, hexagons, etc.

No. Jan is not correct. So, all parallelograms are not rhombuses.

A rhombus is a parallelogram because the opposite sides are parallel but every parallelogram is not a rhombus because all sides may not be equal. Every square is a rectangle because opposite sides are equal but not every rectangle is a square because all sides might not be equal. Every square is rhombus because all sides are equal but not every rhombus is a square because the angles might not be right angles.

here, we have,

We need to identify the properties of the given figure in order to answer why one figure can not be the other one:

A rhombus has all sides equal as well as parallel but all angles might not be right angles.

A square has all four sides equal and has 4 right angles.

A rectangle has equal opposite sides and 4 right angles.

A parallelogram has opposite parallel sides.

Hence, a rhombus can be a parallelogram because the opposite sides are parallel but every parallelogram can not be a rhombus because all sides may not be equal. Every square is a rectangle because opposite sides are equal but not every rectangle is a square because all sides might not be equal. Every square is rhombus because all sides are equal but not every rhombus is a square because the angles might not be right angles.

A parallelogram has opposite sides parallel and equal in length. Also, opposite angles are equal. Squares, rectangles, and rhombuses are all parallelograms. So all parallelograms are not rhombuses.

Not all parallelograms are rhombuses, some parallelograms include rectangles, squares, hexagons, etc.

Answer:

4/8 +6/8 I just verfying the other person's. ok

Step-by-step explanation:

I did it on a calculator ;b

PLEASE MARK FallOutChild brainliest!!

Answer:

4/8 + 6/8 = 10/8 or 1 2/8, 1 1/4

Step-by-step explanation:

When it asks for like units, it's asking for the same denominator value. You can not add fractions together when they do not have a common denominator

if you multiply the denominator and numerator in 2/4 by 2, you get 4/8

Result of 4/8 + 6/8 gives you an improper fraction of 10/8

Answer:

(9,12).

Step-by-step explanation:

If a figure dilated by a scale factor of k and origin is the center of dilation, then the relation between point and its image is defined as

[tex]P(x,y)=P'(kx,ky)[/tex]

It is given that a figure is dilated by a scale factor of 3 and origin is the center of dilation. So,

[tex]P(x,y)=P'(3x,3y)[/tex]

We need to find the image of a vertex located at (3, 4). So, substitute x=3 and y=4 in the above rule of dilation.

[tex]P(3,4)=P'(3(3),3(4))[/tex]

[tex]P(3,4)=P'(9,12)[/tex]

Therefore, the image of a vertex located at (3, 4) is (9,12).

Answer: 9,12

Step-by-step explanation:

Answer:

Given:

Sample size, n = 6965

Sample proportion p' = [tex] \frac{1330}{6965} = 0.19 [/tex]

Let's claim that the return rate is less than​ 20%, ie, P = 0.2

Significance level = 0.01

The null and alternative hypotheses:

H0 : P = 0.2

H1 : P < 0.2

Option A is correct

_____________________________

For the test statistic, Z, let's use the formula:

[tex] Z = \frac{p'- P}{\sqrt{\frac{P(1-P)}{n}}} [/tex]

[tex] = \frac{0.19 - 0.2}{\sqrt{\frac{0.2(1 - 0.2)}{6965}}} = -1.887 [/tex]

Z = -1.887 ≈ -1.89

___________________________

The p-value.

This is a left tailed test.

Using z table,

P-value = P(Z ≤ -1.89) = 0.029

The pvalue is 0.029

Decision:

Because the pvalue, 0.029 is greater than level of significance, 0.01, we fail to reject null hypothesis, H0.

Conclusion:

There is not enough sufficient evidence to conclude that the return rate is less than 20%

Answer:2.5 cups

Step-by-step explanation:

Rosanne runs 6 miles in an hour

If she drinks 0.5 cups of water every  [tex]\frac{1}{3}[/tex]  of an hour

So in 1 hour Rosanne drinks 1.5 cups

So, for 6 miles Rosanne drinks 1.5 cups

i.e. For   [tex]1\ mile \quad \equiv \quad \frac{1}{4}\ \text{cup}[/tex]

for    [tex]10\ mile\quad \equiv \quad \frac{10}{4}\ \text{cup}[/tex]

Step-by-step explanation:

Answer:

$754.05

Step-by-step explanation:

We have to find the volume of one tank and multiply it by the cost of renting the tank per cubic foot.

The volume of a cylinder is:

[tex]V = \pi r^2h[/tex]

where r = radius

h = height

Each tank has a diameter of 8 feet (radius = 4 feet) and a height of 3 feet.

The volume of the tank is therefore:

[tex]V = \pi * 4^2 * 3 = 150.81 ft^3[/tex]

The cost of renting is $5 per cubic foot.

Therefore, the cost of renting a tank is:

150.81 * 5 = $754.05

It costs $754.05 to rent a tank.

Answer:

7t +5

Step-by-step explanation:

6t +7 -2 +t

Combine like terms

6t+t  +7-2

7t +5

Answer:

Relax. The answer is 7t +5

Step-by-step explanation:

Circle the 2 variables (T)

Next re-write the equation and put the varbiles equation 6t+t.

Then you have 7-2 left, you then put it next to the new equation but make sure when you do that it looks like this 6t+t+7-2.

Last you solve and your answer should be 7t+5.

Note: If a variable is alone like the t then make sure you put a one next to it

5. x = 0

6. x = -1

Answer:

49.81

Step-by-step explanation:

the formula I used is distance=[tex]\sqrt{(x_{2}-x_{1})+(y_{2}-y_{1})}[/tex]

Lets say we are finding the distance from c to y

c=(-6,9)

y=(5,9)

cy=[tex]\sqrt{(5-(-6))^{2}+(9-9)^2 }[/tex]

cy=[tex]\sqrt{(11)^2+(0)^2}[/tex]

cy=[tex]\sqrt{121+0}[/tex]

cy=[tex]\sqrt{121}[/tex]

cy=11

And you can find the distance between y and i, i and d, d and o, o and c, using the same formula.

After solving the distance of all I got

yi=16.55294536

id=1

do=9.219544457

oc=12.04159458

After you add them all up you get 49.8140844 which rounded to the nearest hundredth is 48.81.
