HELP WITH GEOMETRY ASAPPPPP

Alecsey [184]

Here's the gist and you can then elaborate:

Proof:
BC = EC, AC = DC (this is given)
angle BCA = angle ECD (vertical angles)
Therefore triangle BCA = triangle ECD (by the side-angle-side theorem).
So therefore BA = ED ( by Congruent Parts of Congruent Triangles are Congruent)

This is not a paragraph proof. You will need to add a little bit more of explanation.

Answer:

80%

Step-by-step explanation:

A percentage can also be represented as a fraction with the denominator of 100. If 80 out of 100 (Fraction Form: $\frac{80}{100}$ ), then 80% of the art club members voted.

A data set is summarized in the frequency table below. Using the table, determine the number of values less than or equal to 6.

Nata [24]

Answer:

Step-by-step explanation:

Given the above table of the data set, the number of values less than or equal to 6 would be the sum of the frequencies of all values that is equal to or less than 6.

From the table above, we would add up the frequencies of the values of 6 and below, which is:

2 + 3 + 6 + 4 + 3 = 18

Answer = 18

College A and College B made it to the state championship

The number of students in vans and bus are (8,22)

Step-by-step explanation:

Let the number of students in the van be “x”

Let the number of students in the bus be “y”

It is given that each bus and van have same number of students.

For college A-

8 vans and 8 bus were rented to ferry 240 students

No of students in 8 bus= 8y (since y students were in each bus)

No of students in 8 van= 8x (since x students were in each van)

Hence 8x+8y=240 cancelling the equation with common factor 8, the equation becomes ⇒ x+ y=30

For College B

4 vans and 1 bus were rented to ferry 54 students

No of students in 1 bus= 1y (since y students were in each bus)

No of students in 4 van= 4x (since x students were in each van)

4x+y=54

Comparing the both equation we get and subtracting equation 2 from 1

x+y-30-4x-y-54=0 ∵ Cancelling y

-3x=-24

∴ x=8 putting the value of x in equation 1 we get y as 22

Thus the answer is (8,22)

What is the approximate volume of the cone?

Mnenie [13.5K]

Answer:

A. 1206 cm³

Step-by-step explanation:

We have a cone and are asked to find the approximate volume of it.

Keep in mind we are using π for 3.14

The forumla of a cone is V = πr² $\frac{h}{3}$

We know the radius = 12

and the height = 8

Substitute :

V = π12² $\frac{8}{3}$

Since these are multiplied with each other, we can first start off with multiplying the fraction, including with factoring 12²:

V = $\frac{2^4*3^2*8\pi }{3}$

Cancel the common factor - 3 :

V = $2^4 * 8 * 3\pi$

Multiply 8 and 3π :

V = $2^4 * 24\pi$

Solve the exponent :

V = $16 * 24\pi$

Multiply :

V = $384\pi$

Multiply for the final answer :

1205.76 cm³

which can be rounded up to

A. 1206 cm³
