Answer:

Step-by-step explanation:

Point G is the centroid of triangle ABC.
C is a vertex of the triangle

D is the midpoint of the side opposite the vertex.

From Centroid Theorems, we know that the distance from the centroid to the vertex is twice as long as the distance from the centroid to the midpoint of the side opposite the vertex.

Therefore:

CG=2DG

Let the length of segment DG =x

The length of segment CG is 6 units greater, therefore: CG=x+6

Substituting into CG=2DG:

x+6=2x

2x-x=6

x=6 Units

Therefore:

CD=CG+GD

=6+6+6

=18 Units

The correct option is C.

I am a decimal

dybincka [34]

0.6<2x<0.65 (because it's closer to 6)
0.3<x<0.325

Since the thousandths digit of 2x is 2, then the thousandths digit of x is 1 or 6, so the decimal could be 0.301, 0.302, 0.311, 0.312, 0.321

Hope this helps :)

Worth 12 Points, i spent 24

Answer:

$\displaystyle m^{\frac{35}{12}}n^{-\frac{28}{15}}=\frac{m^{\frac{35}{12}}}{n^{\frac{28}{15}}}$

Step-by-step explanation:

The relevant rule of exponents is ...

(a^b·c^d)^e = a^(be)·c^(de)

Then ...

(m^(5/4)·n^(-4/5))^(7/3) = m^(5/4·7/3)·n^(-4/5·7/3)

= m^(35/12)·n^(-28/15)

Since you want positive rational exponents, you can write this as ...

= m^(35/12)/n^(28/15)

Hannah is saving money for a car. She earns $160 each week working part time after school and on the weekends at Papa's Pizza. H

Yuliya22 [10]

From the problem we know that Hanna saves one-half of her paycheck each week, so she saves $( \frac{1}{2})(160)= \frac{160}{2} =80$ . Also, we know that her parents put $50 in her savings account each week, so the total amount she and her parents put in her saving's account is $80+50=130$ .
Since we know that Hanna currently has $1,280 in her saving's account and each week she and her parents deposit $130 to the account, with $n$ representing the number of weeks, we can model the situation as follows:
$f(n)=1280+130n$
