Answer:

Step-by-step explanation:

Median = Middle numbers in terms of value

To find the median we are going to want to list the numbers in order from lest to greatest

17, 23, 30, 54, 61, 81

Now we find the middle number

Because there is an even amount of numbers there will be two middle numbers.

When there are two middle numbers we add them together and divide by 2 to get the median

The two middle numbers are 30 and 54

That being said the median = $\frac{30+54}{2}$

30 + 54 = 84

$\frac{84}{2} =42$

So we can conclude that the median of the number set is 42

Answer:

Step-by-step explanation:

(30+54)/2 = 42

30+54 = 84

84/2 = 42

If G is the centroid of triangle ACE, AG = 26, BC = 44, DG = 12, find each missing measure

hram777 [196]

Answer:

Part a) $G.F=13\ units$

Part b) $A.F=39\ units$

Part c) $F.C=22\ units$

Part d) $G.B=24\ units$

Part e) $D.B=36\ units$

Step-by-step explanation:

we know that

The centroid of a triangle is the point where the three median.s coincide.

The centroid is located two thirds of the distance from any vertex of the triangle.

step 1

Find the value of A.F.

we know that

$A.G=\frac{2}{3} A.F$

we have

$A.G=26\ units$

substitute

$26=\frac{2}{3} A.F$

Solve for A.F.

$A.F=26(3)/2$

$A.F=39\ units$

step 2

Find the value of G.F.

$G.F=\frac{1}{3} A.F$

substitute the value of A.F

$G.F=\frac{1}{3} (39)=13\ units$

step 3

Find the value of F.C.

Remember that a median of a triangle is a line segment from one vertex to the mid-point on the opposite side of the triangle

$F.C=\frac{1}{2}B.C$

we have

$B.C=44\ units$

substitute

$F.C=\frac{1}{2}(44)$

$F.C=22\ units$

step 4

Find the value of D.B.

$D.G=\frac{1}{3} D.B$

we have

$D.G=12\ units$

substitute

$12=\frac{1}{3} D.B$

$D.B=12(3)=36\ units$

step 5

Find the value of G.B

$G.B=\frac{2}{3} D.B$

substitute the value of D.B.

$G.B=\frac{2}{3} (36)$

$G.B=24\ units$

Simplify each algebraic expression. 2a +3(a +7)–(3a +3)

erica [24]

Answer:

Step-by-step explanation:

$2a +3(a +7)-(3a +3)\\\\Expand\: 3(a +7) :\\3a+21\\\\=2a+3a+21-\left(3a+3\right)\\\\-(3a+3)=-3a-3\\\\=2a+3a+21-3a-3\\\\Simplify\\\\=2a+18$
