Answer:

To find the area of a trapezoid, you need to know the formula: A=(a+b)/2*h. h is the height, a is the small base, and b is the larger base.

Using the formula, you will get

A=(5+13)/8=72

Plot A shows the number of hours ten girls watched television over a one-week period. Plot B shows the number of hours ten boys

stepan [7]

Answer:

Both the mean and median are greater for Plot A than for Plot B.

Step-by-step explanation:

Plot A data set is : 4,4,5,5,6,6,7,7,10

mean(Plot A) = 5.7

median(Plot A) = 5.5

Plot B data set is : 4,4,5,5,5,6,6,6,7

mean(Plot B) = 5.1

median(Plot B) = 5

Both the mean and median are greater for plot A than for plot B.

Factor the polynomial 12c9 + 28c7. Find the GCF of 12c9 and 28c7. 4c7 Write each term as a product, where one factor is the GCF.

Iteru [2.4K]

We have been given a polynomial $12c^9+28c^7$ . We are asked to factor the given polynomial.

First of all, we will find the greatest common factor of both terms.

GCF of $12$ and $28$ is 4 as 3 times 4 is 12 and 7 times 4 is 28.

GCF of $c^9\text{ and }c^7$ is $c^7$ .

So GCF of $12c^9\text{ and }28c^7$ is $4c^7$ .

Now we will rewrite each term as product of GCF and a term as:

$12c^9=4c^7(3c^2)$

$28c^7=4c^7(7)$

$4c^7(3c^2)+4c^7(7)$

Now we will factor out $4c^7$ from both terms as:

$4c^7(3c^2+7)$

Therefore, factored form of our given expression would be $4c^7(3c^2+7)$ .

A cone has a radius of 10 inches and a height of 6 inches. What is the

ivanzaharov [21]

Answer:

Step-by-step explanation:

radius of cone and hemisphere are the same

volume of half sphere=(1/2)*(4/3)*

=(1/2)*(4/3)*3.14* (4*4*4=64)

=133.97333

=133.97

volume of cone= (1/3)h

=(1/3)*3.14**9 (4*4=16)

=150.72

total volume=133.97+150.72

=284.69

=284.7
