Answer:
5,18,12 cms are the answer.
Step-by-step explanation:
Given is a triangle ABC. Point D is the centroid.
E,F and G are midpoints of CB, BA and AC respectively.
AE, BF and CG are medians of the triangle.
We know that centroid divides the median in the ratio 2:1
Using this we find that AD:DE = 2:1
Or AD+DE:DE = (2+1):1
AE:DE =3:1
15:DE = 3:1 . Hence DE =5 cm.
On the similar grounds we find that DF = 1/3 BF = 9
Hence BD = DF-BF = 27-9 =18 cm
and also
CG = 3/2 times CD = 12 cm.
Answer:
x= -1/2 = -0.500
x=4
Step-by-step explanation:
2x^2-7x-4=0
2x^2-8x+1x-4=0
2x(x-4)+1(x-4)=0
(2x+1)(x-4)=0
2x+1=0...2x= -1.. x= -1/2 x-4=0 .. x=4
checking the solution
2(-1/2)^2-7(-1/2)=4..... 4=4
2(4)^2-7(4)=4....... 4=4
Answer:
6 %
Step-by-step explana
100 pennies makes a dollar... you just add 5 for the nickel and 1 fo the penny and it makes 6
So for this problem we need to do order of operations so the very first step that we need to do here is (8+2) because that is the smallest enclosed symbols (8+2)=10 next divide by 20 because that is the next step in the equation which 20/10=2, so now we have {[2]^6+6} and due to order of operations the next step here is to take 2 to the power of 6 which is 64 so now we have {64+6} which is 70 so now we have 70/(4^2/2) and due to order of operations we do the parentheses first and that would mean that we do 4^2 because exponents come after parantheses like so,
70/(16/2) now we do 16/2 because its still inside the paranthesess so 16/2=8 so now we have 70/8 and that equals are end answer of 8.75 Enjoy!=)
